The report's findings suggest that, in the absence of significant alterations in resource utilization and environmental destruction, it is highly likely that there will be an abrupt and unmanageable decrease in both population and industrial capacity. Although it faced severe criticism and scrutiny upon its release, the report influenced environmental reforms for decades. Subsequent analysis notes that global use of natural resources has been inadequately reformed to alter its expected outcome.{{efn|See section [[#Comparisons and updated models]].}} Yet [[Simon–Ehrlich wager|price predictions based on]] [[Resource depletion|resource scarcity]] failed to materialize in the years since publication.

[[File:Limits to Growth fig. 49.png|thumb|[[World3]] Model Standard Run as shown in ''The Limits to Growth''.]]

==Purpose==
In commissioning the MIT team to undertake the project that resulted in ''LTG'', the [[Club of Rome]] had three objectives:<ref name="Meadows-1972" />{{RP|185}}
# Gain insights into the limits of our world system and the constraints it puts on human numbers and activity.
# Identify and study the dominant elements, and their interactions, that influence the long-term behavior of world systems.
# To warn of the likely outcome of contemporary economic and industrial policies, with a view to influencing changes to a [[sustainable lifestyle]].

==Method==
The World3 model is based on five variables: "[[world population|population]], [[Food industry|food production]], [[Industrialisation|industrialization]], [[pollution]], and [[resource depletion|consumption of nonrenewable natural resources]]".<ref name="Meadows-1972" />{{RP|25}} At the time of the study, all these variables were increasing and were assumed to continue to grow [[exponential growth|exponentially]], while the ability of technology to increase resources grew only [[linear function|linearly]].<ref name="Meadows-1972" /> The authors intended to explore the possibility of a sustainable feedback pattern that would be achieved by altering growth trends among the five variables under three scenarios. They noted that their projections for the values of the variables in each scenario were predictions "only in the most limited sense of the word", and were only indications of the system's behavioral tendencies.<ref name="Peter A. Victor 2008 pp. 92-93">{{Cite book |last=Victor |first=Peter A. |url=https://www.worldcat.org/oclc/247022295 |title=Managing without growth : slower by design, not disaster |date=2008 |publisher=Edward Elgar |isbn=978-1-84844-299-3 |location=Cheltenham, UK |oclc=247022295}}</ref> Two of the scenarios saw "overshoot and collapse" of the global system by the mid- to latter-part of the 21st century, while a third scenario resulted in a "stabilized world".<ref name="CSIRO" />{{RP|11}}

===Exponential reserve index===
A key idea in ''The Limits to Growth'' is the notion that if the rate of resource use is increasing, the number of reserves cannot be calculated by simply taking the current known reserves and dividing them by the current yearly usage, as is typically done to obtain a static index. For example, in 1972, the amount of [[chromium]] reserves was 775 million metric tons, of which 1.85&nbsp;million metric tons were mined annually. The static index is 775/1.85=418 years, but the rate of chromium consumption was growing at 2.6 percent annually, or [[exponential growth|exponentially]].<ref name="Meadows-1972" />{{RP|54–71}} If instead of assuming a constant rate of usage, the assumption of a constant rate of growth of 2.6 percent annually is made, the resource will instead last
:<math>\frac{\ln(1+0.026\times 418)}{0.026} \approx \text{95 years}</math>

In general, the formula for calculating the amount of time left for a resource with constant consumption growth is:<ref>Limits To Growth, pg 60, Derivation: <math> R = \int_0^y C e^{\rho t}\ dt = \frac{C}{\rho} \left(e^{\rho y} - 1\right) </math> reverts to <math>y = \frac{\ln \left( 1 + \rho \frac{R}{C}\right)}{\rho}.</math></ref>
:<math>y = \frac{\ln((rs) + 1)}{r}</math>
where:
:''y'' = years left;
:''r'' = the [[continuous compounding]] growth rate;
:''s'' = R/C or static reserve;
:''R'' = reserve;
:''C'' = (annual) consumption.

==== Commodity reserve extrapolation ====
The chapter contains a large table that spans five pages in total, based on actual geological reserves data for a total of 19 non-renewable resources, and analyzes their reserves at 1972 modeling time of their exhaustion under three scenarios: static (constant growth), exponential, and exponential with reserves multiplied by 5 to account for possible discoveries. A short excerpt from the table is presented below:
:{| class="wikitable"

|}

The chapter also contains a detailed computer model of chromium availability with current (as of 1972) and double the known reserves as well as numerous statements on the current increasing price trends for discussed metals:

{{Blockquote|text=Given present resources consumption rates and the projected increase in the rates, the great majority of the currently important nonrenewable resources will be extremely costly 100 years from now. (...) The prices of those resources with the shortest static reserve indices have already begun to increase. The price of mercury, for example, has gone up 500 percent in the last 20 years; the price of lead has increased 300 percent in the last 30 years.|author=|title=|source=Chapter 2, page 66}}

==== Interpretations of the exhaustion model ====
Due to the detailed nature and use of actual resources and their real-world price trends, the indexes have been interpreted as a prediction of the number of years until the world would "run out" of them, both by environmentalist groups calling for greater conservation and restrictions on use and by skeptics criticizing the accuracy of the predictions.<ref>''[[The Skeptical Environmentalist]]'', p. 121</ref>{{failed verification|date=November 2017}}<ref>{{Cite web |title=Chapter 17: Growth and Productivity-The Long-Run Possibilities<!-- Bot generated title --> |url=http://www.oswego.edu/~edunne/200ch17.html |archive-url=https://web.archive.org/web/20101218063522/http://www.oswego.edu/~edunne/200ch17.html |archive-date=18 December 2010 |url-status=dead}}</ref><ref>{{Cite news |date=19 September 2002 |title=Treading lightly |newspaper=[[The Economist]] |url=https://www.economist.com/finance-and-economics/2002/09/19/treading-lightly |url-status=live |url-access=subscription |archive-url=https://web.archive.org/web/20190515052804/https://www.economist.com/finance-and-economics/2002/09/19/treading-lightly |archive-date=15 May 2019}}</ref><ref>{{Cite news |last=Bailey |first=Ronald |date=4 February 2004 |title=Science and Public Policy |work=Reason |url=http://reason.com/archives/2004/02/04/science-and-public-policy |access-date=26 November 2017}}</ref> This interpretation has been widely propagated by media and environmental organizations, and authors who, apart from a note about the possibility of the future flows being "more complicated", did not clearly constrain or deny this interpretation.<ref>{{Cite book |title=Limits to Growth |year=1972 |pages=63 |quote=Of course, the actual nonrenewable resource availability in the next few decades will be determined by factors much more complicated that can be expressed by either the simple static reserve index or the exponential reserve index.

While environmental organizations used it to support their arguments, a number of economists used it to criticize ''LTG'' as a whole shortly after publication in the 1970s (Peter Passel, Marc Roberts, and Leonard Ross), with similar criticism reoccurring from Ronald Baily, George Goodman and others in the 1990s.<ref name="Bardi-2011" /> In 2011 Ugo Bardi in "The Limits to Growth Revisited" argued that "nowhere in the book was it stated that the numbers were supposed to be read as predictions", nonetheless as they were the only tangible numbers referring to actual resources, they were promptly picked as such by both supporters as well as opponents.<ref name="Bardi-2011" /> 

While Chapter 2 serves as an introduction to the concept of exponential growth modeling, the actual World3 model uses an abstract "non-renewable resources" component based on static coefficients rather than the actual physical commodities described above.

==Conclusions==
After reviewing their computer simulations, the research team came to the following conclusions:<ref name="Meadows-1972" />{{RP|23–24}}
{{blockquote| <!-- note to editors: this is a verbatim quotation, please do not try to change it -->
# If the present growth trends in [[world population]], industrialization, pollution, [[Agriculture|food production]], and resource depletion continue unchanged, the limits to growth on this planet will be reached sometime within the next one hundred years.{{efn|from 1972, so 2072}} The most probable result will be a rather sudden and uncontrollable decline in both population and industrial capacity.
# It is possible to alter these growth trends and to establish a condition of ecological and economic stability that is sustainable far into the future. The state of global equilibrium could be designed so that the basic material needs of each person on earth are satisfied and each person has an equal opportunity to realize his individual human potential.
# If the world's people decide to strive for this second outcome rather than the first, the sooner they begin working to attain it, the greater will be their chances of success.
|source=''Limits to Growth'', Introduction}}

The introduction goes on to say:
{{blockquote|These conclusions are so far-reaching and raise so many questions for further study that we are quite frankly overwhelmed by the enormity of the job that must be done. We hope that this book will serve to interest other people, in many fields of study and in many countries of the world, to raise the space and time horizons of their concerns, and to join us in understanding and preparing for a period of great transition{{snd}} the transition from growth to global equilibrium.}}

==Criticism==
{{See also|Malthusian#Criticism|Club of Rome#Critics}}
''LTG'' provoked a wide range of responses, including immediate criticisms almost as soon as it was published.<ref>{{Cite journal |last=Kaysen |first=Carl |year=1972 |title=The Computer That Printed out W*O*L*F* |journal=Foreign Affairs |volume=50 |issue=4 |pages=660–668 |doi=10.2307/20037939 |jstor=20037939}}</ref><ref>{{Cite journal |last=Solow |first=Robert M. |year=1973 |title=Is the End of the World at Hand? |journal=Challenge |volume=16 |issue=1 |pages=39–50 |doi=10.1080/05775132.1973.11469961 |jstor=40719094}}</ref>

Peter Passell and two co-authors published a 2 April 1972 article in the ''New York Times'' describing ''LTG'' as "an empty and misleading work&nbsp;... best summarized&nbsp;... as a rediscovery of the oldest maxim of computer science: [[Garbage in, garbage out|Garbage In, Garbage Out]]". Passell found the study's simulation to be simplistic while assigning little value to the role of technological progress in solving the problems of [[resource depletion]], pollution, and food production. They charged that all ''LTG'' simulations ended in collapse, predicting the imminent end of irreplaceable resources. Passell also charged that the entire endeavour was motivated by a hidden agenda: to halt growth in its tracks.<ref>{{Cite news |last1=Passell |first1=Peter |last2=Roberts |first2=Marc |last3=Ross |first3=Leonard |author-link3=Leonard Ross |date=2 April 1972 |title=The Limits to Growth |work=The New York Times |url=https://www.nytimes.com/1972/04/02/archives/the-limits-to-growth-a-report-for-the-club-of-romes-project-on-the.html |access-date=2 December 2017}}</ref>

In 1973, a group of researchers at the [[Science Policy Research Unit]] at the [[University of Sussex]] concluded that simulations in ''Limits to Growth'' were very sensitive to a few key assumptions and suggest that the MIT assumptions were unduly pessimistic, and the MIT methodology, data, and projections were faulty.<ref>{{Cite book |url=https://www.worldcat.org/oclc/674851 |title=Models of doom : a critique of The limits to growth |date=1973 |publisher=Universe Publishing |isbn=0-87663-184-7 |editor-last=Cole |editor-first=H.

R.}}</ref>  However, the ''LTG'' team, in a paper entitled "A Response to Sussex", described and analyzed five major areas of disagreement between themselves and the Sussex authors.<ref>{{Cite journal |last1=Meadows |first1=Donella H |last2=Meadows |first2=Dennis L |last3=Randers |first3=Jørgen |last4=Behrens III |first4=William W |date=February 1973 |title=A response to Sussex |journal=Futures |volume=5 |issue=1 |pages=135–152 |doi=10.1016/0016-3287(73)90062-1}}</ref> The team asserted that the Sussex critics applied "micro reasoning to macro problems", and suggested that their own arguments had been either misunderstood or wilfully misrepresented. They pointed out that the critics had failed to suggest any alternative model for the interaction of growth processes and resource availability, and "nor had they described in precise terms the sort of social change and technological advances that they believe would accommodate current growth processes."

During that period, the very idea of any worldwide constraint, as indicated in the study, was met with scepticism and opposition by both businesses and the majority of economists.<ref>{{Cite book |last1=Meyer |first1=N.

Wallich]] agreed that growth could not continue indefinitely, but that a natural end to growth was preferable to intervention. Wallich stated that technology could solve all the problems the report was concerned about, but only if growth continued apace. According to Wallich's cautionary statement, prematurely halting progress would result in the perpetual impoverishment of billions.<ref name="alan201013" />

[[Julian Simon]], a professor at the Universities of [[University of Illinois|Illinois]] and, later, [[University of Maryland|Maryland]], argued that the fundamental underlying concepts of the LTG scenarios were faulty because the very idea of what constitutes a "resource" varies over time. For instance, wood was the primary shipbuilding resource until the 1800s, and there were concerns about prospective wood shortages from the 1500s on. But then boats began to be made of iron, later steel, and the shortage issue disappeared. Simon argued in his book ''[[The Ultimate Resource]]'' that human ingenuity creates new resources as required from the raw materials of the universe.  For instance, copper will never "run out". History demonstrates that as it becomes scarcer its price will rise and more will be found, more will be recycled, new techniques will use less of it, and at some point a better substitute will be found for it altogether.<ref>{{Cite book |last=Simon |first=Julian |url=https://archive.org/details/ultimateresource00juli |title=The Ultimate Resource |date=August 1981 |publisher=Princeton University Press |isbn=069109389X |edition=Hardcover |location=Princeton}}</ref> His book was revised and reissued in 1996 as ''The Ultimate Resource 2''.<ref>{{Cite book |last=Simon |first=Julian L |url=https://archive.org/details/ultimateresource00simo |title=The Ultimate Resource 2 |date=1996 |publisher=Princeton University Press |isbn=0691042691 |edition=Paperback |location=Princeton |access-date=6 December 2017}}</ref>

To the US Congress in 1973,  [[Allen V. Kneese]] and Ronald Riker of [[Resources for the Future]] (RFF) testified that in their view, "The authors load their case by letting some things grow exponentially and others not. Population, capital and pollution grow exponentially in all models, but technologies for expanding resources and controlling pollution are permitted to grow, if at all, only in discrete increments."  However, their testimony also noted the possibility of "relatively firm long-term limits" associated with [[carbon dioxide emissions]], that humanity might "loose upon itself, or the [[ecosystem service]]s on which it depends, a disastrously virulent substance", and (implying that population growth in "developing countries" is problematic) that "we don't know what to do about it".<ref>{{Cite book |last=United States Congress House Committee on Merchant Marine and Fisheries Subcommittee on Fisheries and Wildlife Conservation |url=https://books.google.com/books?id=tBbSAAAAMAAJ&q=%22The+authors+load+their+case+by+letting+some+things+grow+exponentially+and+others+not.+Population%2C+capital+and+pollution+grow+exponentially+in+all+models%2C+but+technologies+for+expanding+resources+and+controlling+pollution+are+permitted+to+grow%2C+if+at+all%2C+only+in+discrete+increments.%22&pg=PA203 |title=Growth and Its Implications for the Future: Hearing with Appendix, Ninety-third Congress, First[-second] Session .... |date=1973 |publisher=U.S. Government Printing Office |language=en}}, pp 203–205</ref>

In 1997, the Italian economist Giorgio Nebbia observed that the negative reaction to the ''LTG'' study came from at least four sources: those who saw the book as a threat to their business or industry; professional economists, who saw ''LTG'' as an [[credentialism|uncredentialed]] encroachment on their professional [[wikt:perquisite|perquisites]]; the Catholic church, which bridled at the suggestion that overpopulation was one of mankind's major problems; finally, the political left, which saw the ''LTG'' study as a scam by the elites designed to trick workers into believing that a proletarian paradise was a [[wikt:pipe dream|pipe dream]].<ref name="Bardi-2008" /> A [[UK]] government report found that "In the 1990s, criticism tended to focus on the misconception that ''Limits to Growth'' predicted global resource depletion and social collapse by the end of the year 2000".<ref name="Jackon-2016" />

Peter Taylor and [[Frederick H. Buttel|Frederick Buttle]]’s interpretation of the ''LTG'' study and the associated [[system dynamics]] (SD) models found that the original SD was created for firms and set the pattern for urban, global, and other SD models. These firm-based SDs relied on superintending managers to prevent undesirable cycling and feedback loops caused by separate common-sense decisions made by individual sectors. However, the later global model lacked superintending managers that enforce interrelated world-level changes, making undesirable cycles and [[exponential growth]] and collapse happen in nearly all models no matter the parameter settings. There was no way for a few individuals in the model to override the structure of the system even if they understood the system as a whole. This meant there were only two solutions: convincing everyone in the system to change the basic structure of population growth and collapse (moral response) and/or having a superintending agency analyzing the system as a whole and directing changes (technocratic response). The ''LTG'' report combined these two approaches multiple times. System dynamists constructed interventions into the world model to demonstrate how their proposed interventions improved the system to prevent collapse. The SD model also aggregated the world’s population and resources which meant that it did not demonstrate how crises emerge at different times and in different ways without any strictly global logic or form because of the unequal distributions of populations and resources. These issues indicate that the local, national, and regional differentiation in politics and economics surrounding [[Environmental sociology|socioenvironmental]] change was excluded from the SD used by ''LTG'', making it unable to accurately demonstrate real-world dynamics.<ref>{{Cite journal |last1=Taylor |first1=Peter J. |last2=Buttel |first2=Frederick H. |date=1992 |title=How do we know we have global environmental problems?

==Positive reviews==
{{quote box
| quote = With few exceptions, economics as a discipline has been dominated by a perception of living in an unlimited world, where resource and pollution problems in one area were solved by moving resources or people to other parts. The very hint of any global limitation as suggested in the report ''The Limits to Growth'' was met with disbelief and rejection by businesses and most economists. However, this conclusion was mostly based on false premises.

In 1980, the [[The Global 2000 Report to the President|Global 2000 Report to the President]] arrived at similar conclusions regarding expected global resource scarcity, and the need for multilateral coordination to prepare for this situation.<ref>{{Cite journal |last=Pierre |first=Andrew J. |date=Spring 1981 |title=Capsule Review – The Global 2000 Report to the President.

In a 2008 blog post, [[Ugo Bardi]] commented that "Although, by the 1990s ''LTG'' had become everyone's laughing stock, among some the ''LTG'' ideas are becoming again popular".<ref name="Bardi-2008">{{Cite web |last=Bardi |first=Ugo |date=9 March 2008 |title=Cassandra's Curse: How ''The Limits to Growth'' was demonized |url=http://www.sustainable.soltechdesigns.com/cassandra.html |access-date=1 December 2017 |website=The Oil Drum: Europe}}</ref> Reading ''LTG'' for the first time in 2000, [[Matthew Simmons]] concluded his views on the report by saying, "In hindsight, The [[Club of Rome]] turned out to be right. We simply wasted 30 important years ignoring this work."<ref>{{Cite web |last=Simmons |first=Matthew R. |date=October 2000 |title=Revisiting The Limits to Growth: Could the Club of Rome Have Been Correct After All? |url=http://www.mudcitypress.com/PDF/clubofrome.pdf |access-date=29 November 2017 |website=Mud City Press}}</ref>

[[Robert Solow]], who had been a vocal critic of LTG, said in 2009 that "thirty years later, the situation may have changed... it will probably be more important in the future to deal intellectually, quantitatively, as well as practically, with the mutual interdependence of economic growth, natural resource availability, and environmental constraints".<ref>{{Cite journal |last=Solow |first=Robert M. |date=2009-12-01 |title=Does Growth Have a Future?

In a study conducted in 2008, Graham Turner from CSIRO discovered a significant correlation between the observed historical data spanning from 1970 to 2000 and the simulated outcomes derived from the "standard run" limits of the growth model. This correlation was apparent across nearly all the reported outputs. The comparison falls comfortably within the range of uncertainty for almost all the available data, both in terms of magnitude and the patterns observed over time. Turner conducted an analysis of many studies, with a special focus on those authored by economists, that have consistently aimed to discredit the limits-to-growth concept over the course of several years. According to Turner, the aforementioned studies exhibit flaws and demonstrate a lack of comprehension regarding the model.<ref name="CSIRO" />{{RP|37}}

Turner reprised these observations in another opinion piece in ''[[The Guardian]]'' on 2 September 2014. Turner used data from the UN to claim that the graphs almost exactly matched the 'Standard Run' from 1972 (i.e. the worst-case scenario, assuming that a 'business as usual' attitude was adopted, and there were no modifications of human behaviour in response to the warnings in the report). Birth rates and death rates were both slightly lower than projected, but these two effects cancelled each other out, leaving the growth in world population almost exactly as forecast.<ref>{{Cite news |last1=Turner |first1=Graham |last2=Alexander |first2=Cathy |date=2 September 2014 |title=Limits to Growth was right.

In 2010, Nørgård, Peet and Ragnarsdóttir called the book a "pioneering report", and said that it "has withstood the test of time and, indeed, has only become more relevant."<ref name="Nørgård-2010">{{Cite journal |last1=Nørgård |first1=Jørgen Stig |last2=Peet |first2=John |last3=Ragnarsdóttir |first3=Kristín Vala |date=March 2010 |title=The History of The Limits to Growth |url=http://www.thesolutionsjournal.com/node/569 |url-status=dead |journal=The Solutions Journal |volume=1 |issue=2 |pages=59–63 |archive-url=https://web.archive.org/web/20140720093436/http://thesolutionsjournal.com/node/569 |archive-date=20 July 2014 |access-date=1 July 2014}}</ref>

In 2012, [[Christian Parenti]] drew comparisons between the reception of ''The Limits to Growth'' and the ongoing [[global warming controversy]]. Parenti further remarked that despite its scientific rigour and credibility, the intellectual guardians of influential economic interests actively dismissed LTG as a warning. A parallel narrative is currently unfolding within the realm of climate research.<ref>{{Cite journal |last=Parenti |first=Christian |date=5 December 2012 |title='The Limits to Growth': A Book That Launched a Movement |url=https://www.thenation.com/article/limits-growth-book-launched-movement/ |journal=[[The Nation]] |issue=24–31 December 2012 issue |access-date=30 November 2017 |archive-date=1 December 2017 |archive-url=https://web.archive.org/web/20171201050432/https://www.thenation.com/article/limits-growth-book-launched-movement/ |url-status=dead }}</ref>

In 2012, [[John Scales Avery]], a member of the Nobel Prize (1995) winning group associated with the [[Pugwash Conferences]] on Science and World Affairs, supported the basic thesis of ''LTG'' by stating, <blockquote>Although the specific predictions of resource availability in ''Limits to Growth'' lacked accuracy, its basic thesis&nbsp;– that unlimited economic growth on a finite planet is impossible – was indisputably correct.<ref>{{Cite book |last=Avery |first=John Scales |title=Information Theory and Evolution |publisher=[[World Scientific]] |year=2012 |isbn=978-981-4401-22-7 |location=Singapore |pages=233}}</ref></blockquote>

The [[Club of Rome]] has persisted after ''The Limits to Growth'' and has generally provided comprehensive updates to the book every five years.

An independent retrospective on the public debate over ''The Limits to Growth'' concluded in 1978 that optimistic attitudes had won out, causing a general loss of momentum in the environmental movement. While summarizing a large number of opposing arguments, the article concluded that "scientific arguments for and against each position&nbsp;... have, it would seem, played only a small part in the general acceptance of alternative perspectives."<ref>{{Cite journal |last=Sandbach |first=Francis |date=1 November 1978 |title=The Rise and Fall of the Limits to Growth Debate |journal=Social Studies of Science |volume=8 |issue=4 |pages=495–520 |doi=10.1177/030631277800800404 |pmid=11610433 |s2cid=1564426}}</ref>

In 1989, a symposium was held in [[Hanover]], entitled "Beyond the Limits to Growth: Global Industrial Society, Vision or Nightmare?" and in 1992, ''[[Beyond the Limits]]'' (BTL) was published as a 20-year update on the original material. It "concluded that two decades of history mainly supported the conclusions we had advanced 20 years earlier. But the 1992 book did offer one major new finding. We suggested in BTL that humanity had already overshot the limits of Earth's support capacity."<ref name="Meadows2004">{{Cite book |last1=Meadows |first1=Donella |title=Limits to Growth: The 30-Year Update |last2=Randers |first2=Jurgen |last3=Meadows |first3=Dennis |date=2004 |publisher=Chelsea Green Publishing Co |location=Vermont, USA |page=xii}}</ref>

''Limits to Growth: The 30-Year Update'' was published in 2004. The authors observed that "It is a sad fact that humanity has largely squandered the past 30 years in futile debates and well-intentioned, but halfhearted, responses to the global ecological challenge. We do not have another 30 years to dither. Much will have to change if the ongoing overshoot is not to be followed by collapse during the twenty-first century."<ref name="Meadows2004" />

In 2012, the [[Smithsonian Institution]] held a symposium entitled "Perspectives on ''Limits to Growth''".<ref>{{Cite web |date=1 March 2012 |title=Perspectives on Limits to Growth: Challenges to Building a Sustainable Planet |url=https://www.si.edu/Content/consortia/limits-to-growth.pdf |access-date=28 November 2017 |website=Smithsonian Institution |publisher=Smithsonian Institution—Club of Rome}}</ref> Another symposium was held in the same year by the [[Volkswagen Foundation]], entitled "Already Beyond?"<ref>{{Cite web |title=Documentation: "Already Beyond? – 40 Years Limits to Growth" |url=https://www.volkswagenstiftung.de/en/events/event-reports/berichte/documentation-limits-to-growth.html |access-date=28 November 2017 |website=Volkswagen Stiftung}}</ref>

''Limits to Growth'' did not receive an official update in 2012, but one of its coauthors, [[Jørgen Randers]], published a book, ''[[2052: A Global Forecast for the Next Forty Years]]''.<ref>{{Cite book |last=Randers |first=Jorgen |title=2052.

===Comparisons and updated models <span class="anchor" id="Validation"></span>===
In 2008, physicist Graham Turner{{efn|Dr Turner is an Honorary Senior Fellow with the Melbourne Sustainable Society Institute at the University of Melbourne.}} at the [[Commonwealth Scientific and Industrial Research Organisation]] (CSIRO) in Australia published a paper called "A Comparison of 'The Limits to Growth' with Thirty Years of Reality".<ref name="CSIRO">{{Cite journal |last=Turner |first=Graham |date=2008 |title=A Comparison of 'The Limits to Growth' with Thirty Years of Reality |url=https://publications.csiro.au/rpr/pub?list=BRO&pid=csiro:EP111264 |journal=Socio-Economics and the Environment in Discussion (SEED). CSIRO Working Paper Series |publisher=Commonwealth Scientific and Industrial Research Organisation ([[CSIRO]]) |volume=2008–09 |page=52 |doi=10.1016/j.gloenvcha.2008.05.001 |issn=1834-5638 |access-date=25 July 2021}}</ref> It compared the past thirty years of data with the eleven scenarios laid out in the 1972 book and found that changes in industrial production, food production, and pollution are all congruent with one of the book's eleven scenarios—that of "business as usual". This scenario in ''Limits'' points to [[economic collapse|economic]] and [[societal collapse]] in the 21st century.<ref>[https://www.newscientist.com/article/dn16058-prophesy-of-economic-collapse-coming-true.html "Prophesy of economic collapse 'coming true'"], by Jeff Hecht, ''[[New Scientist]]'', 17 November 2008</ref> In 2010, Nørgård, Peet, and Ragnarsdóttir called the book a "pioneering report". They said that, "its approach remains useful and that its conclusions are still surprisingly valid ... unfortunately the report has been largely dismissed by critics as a doomsday prophecy that has not held up to scrutiny."<ref name="Nørgård-2010" />

Also in 2008, researcher Peter A. Victor wrote that even though the ''Limits'' team probably underestimated [[price mechanism]]'s role in adjusting outcomes, their critics have overestimated it. He states that ''Limits to Growth'' has had a significant impact on the conception of environmental issues and notes that (in his view) the models in the book were meant to be taken as predictions "only in the most limited sense of the word".<ref name="Peter A. Victor 2008 pp. 92-93" />

In a 2009 article published in ''[[American Scientist]]'' entitled ''Revisiting the Limits to Growth After Peak Oil,'' Hall and Day noted that "the values predicted by the limits-to-growth model and actual data for 2008 are very close."<ref>{{Cite journal |last1=Hall |first1=Charles A. S. |author-link=Charles A. S. Hall |last2=John W.

[of the ''Limits to Growth''] "standard run" scenario, which results in collapse of the global system midway through the 21st Century."<ref name="CSIRO" />

In 2011, [[Ugo Bardi]] published a book-length academic study of ''The Limits to Growth'', its methods, and historical reception and concluded that "The warnings that we received in 1972 ... are becoming increasingly more worrisome as reality seems to be following closely the curves that the ... scenario had generated."<ref name="Bardi-2011">{{Cite book |last=Bardi |first=Ugo |url=https://books.google.com/books?id=Gj0RmQWGfXcC&q=the+limits+to+growth+revisited&pg=PP1 |title=The Limits to Growth Revisited |date=2011 |publisher=Springer |isbn=9781441994158 |location=New York |access-date=27 November 2017}}</ref>{{RP|3}} A popular analysis of the accuracy of the report by science writer [[Richard Heinberg]] was also published.<ref>{{Cite book |last=Heinberg |first=Richard |title=The End of Growth: Adapting to Our New Economic Reality |date=2011 |publisher=New Society Publishers |isbn=978-0865716957 |edition=3rd printing |location=Gabriola Island, BC}}</ref>

In 2012, writing in ''[[American Scientist]]'', Brian Hayes stated that the model is "more a polemical tool than a scientific instrument". He went on to say that the graphs generated by the computer program should not, as the authors note, be used as predictions.<ref>{{Cite journal |last=Brian Hayes |date=May–June 2012 |title=Computation and the Human Predicament – The Limits to Growth and the Limits to Computer Modeling |url=https://www.americanscientist.org/article/computation-and-the-human-predicament |journal=American Scientist |doi=10.1511/2012.96.186}}</ref>

In 2014, Turner concluded that "preparing for a collapsing global system could be even more important than trying to avoid collapse."<ref>{{Cite book |last=Turner |first=Graham |url=http://sustainable.unimelb.edu.au/sites/default/files/docs/MSSI-ResearchPaper-4_Turner_2014.pdf |title=Is Global Collapse Imminent? |date=August 2014 |publisher=Melbourne Sustainable Society Institute, The University of Melbourne |isbn=978-0-7340-4940-7 |editor-last=Rickards |editor-first=Lauren |series=MSSI Research Papers |location=Melbourne, Australia |page=16 |type=Research Paper No. 4 |quote=Regrettably, the alignment of data trends with the LTG dynamics indicates that the early stages of collapse could occur within a decade, or might even be underway.

In 2015, a calibration of the updated World3-03 model using historical data from 1995 to 2012 to better understand the dynamics of today's economic and resource system was undertaken. The results showed that human society has invested more to abate persistent pollution, increase food productivity and have a more productive service sector however the broad trends within ''Limits to Growth'' still held true.<ref>{{Cite journal |last1=Pasqualino |first1=Roberto |last2=Jones |first2=Aled |last3=Monasterolo |first3=Irene |last4=Phillips |first4=Alex |date=2015 |title=Understanding Global Systems Today—A Calibration of the World3-03 Model between 1995 and 2012 |journal=Sustainability |publisher=MDPI |volume=7 |issue=8 |pages=9864–9889 |doi=10.3390/su7089864 |doi-access=free|bibcode=2015Sust....7.9864P }}</ref>

In 2016, a group of MPs in the [[UK]] established an [[All-party parliamentary group]] on Limits to Growth. Its initial report concluded that "there is unsettling evidence that society is still following the 'standard run' of the original study – in which overshoot leads to an eventual collapse of production and living standards".<ref name="Jackon-2016">{{Cite report |url=http://limits2growth.org.uk/wp-content/uploads/2016/04/Jackson-and-Webster-2016-Limits-Revisited.pdf |title=Limits Revisited: A Review of the Limits to Growth Debate |last1=Jackon |first1=Tim |last2=Webster |first2=Robin |date=April 2016 |publisher=All-Party Parliamentary Group on Limits to Growth |location=London |access-date=23 October 2016}}</ref> The report also points out that some issues not fully addressed in the original 1972 report, such as [[climate change]], present additional challenges for human development.

In 2020, an analysis by [[Gaya Herrington]], then Director of Sustainability Services of [[KPMG|KPMG US]],<ref name="Szymańska-2015">{{Cite web |last=Szymańska |first=Julka |date=21 July 2015 |title=The Netherlands: An Interview with Gaya Branderhorst of Straatintimidatie |url=https://stopstreetharassment.org/2015/07/branderhorst-of-straatintimidatie/ |archive-url=https://web.archive.org/web/20220628155936/https://stopstreetharassment.org/2015/07/branderhorst-of-straatintimidatie/ |archive-date=28 June 2022 |access-date=28 June 2022 |website=Stop Street Harassment}}</ref> was published in [[Yale University]]'s ''[[Journal of Industrial Ecology]]''.<ref name="Herrington">{{Cite journal |last=Herrington |first=Gaya |author-link=Gaya Herrington |date=June 2021 |title=Update to limits to growth: Comparing the World3 model with empirical data |url=https://onlinelibrary.wiley.com/doi/10.1111/jiec.13084 |journal=Journal of Industrial Ecology |language=en |volume=25 |issue=3 |pages=614–626 |doi=10.1111/jiec.13084 |bibcode=2021JInEc..25..614H |issn=1088-1980 |s2cid=226019712}}, published online 03 Nov 2020</ref> The study assessed whether, given key data known in 2020 about factors important for the "Limits to Growth" report, the original report's conclusions are supported. In particular, the 2020 study examined updated quantitative information about ten factors, namely population, fertility rates, mortality rates, industrial output, food production, services, non-renewable resources, persistent pollution, human welfare, and ecological footprint, and concluded that the "Limits to Growth" prediction is essentially correct in that continued economic growth is unsustainable under a "business as usual" model.<ref name="Herrington" /> The study found that current empirical data is broadly consistent with the 1972 projections and that if major changes to the consumption of resources are not undertaken, economic growth will peak and then rapidly decline by around 2040.<ref>{{Cite news |last=Ahmed |first=Nafeez |date=14 July 2021 |title=MIT Predicted in 1972 That Society Will Collapse This Century.
