Do you think nobody has thought to compare? "" n 2020, an analysis by Gaya Herrington, then Director of Sustainability Services of KPMG US,[52] was published in Yale University's Journal of Industrial Ecology.[53] 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.[53] 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.[54][55] In 2023, the parameters of the World3 model were recalibrated using empirical data up to 2022. [56] This improved parameter set results in a World3 simulation that shows the same overshoot and collapse mode in the coming decade as the original business-as-usual scenario of the Limits to Growth standard run. The main effect of the recalibration update is to raise the peaks of most variables and move them a few years into the future. ""
