“A report commissioned on behalf of a cross-party group of British MPs authored by a former UK government advisor, the first of its kind, says that industrial civilisation is currently on track to experience “an eventual collapse of production and living standards” in the next few decades if business-as-usual continues.

The report published by the new All-Party Parliamentary Group (APPG) on Limits to Growth, which launched in the House of Commons on Tuesday evening, reviews the scientific merits of a controversial 1972 model by a team of MIT scientists, which forecasted a possible collapse of civilisation due to resource depletion.

The report launch at the House of Commons was addressed by Anders Wijkman, co-chair of the Club of Rome, which originally commissioned the MIT study.

At the time, the MIT team’s findings had been widely criticised in the media for being alarmist. To this day, it is often believed that the ‘limits to growth’ forecasts were dramatically wrong.

But the new report by the APPG on Limits to Growth, whose members consist of Conservative, Labour, Green and Scottish National Party members of parliament, reviews the scientific literature and finds that the original model remains surprisingly robust.

Authored by Professor Tim Jackson of the University of Surrey, who was Economics Commissioner on the UK government’s Sustainable Development Commission, and former Carbon Brief policy analyst Robin Webster, the report concludes that:

“There is unsettling evidence that society is tracking the ‘standard run’ of the original study — which leads ultimately to collapse. Detailed and recent analyses suggest that production peaks for some key resources may only be decades away.”

The 1972 team used their system dynamics model of the consumption of key planetary resources to explore a range of different scenarios.

As Professor Jackson and Webster explain in the new APPG report:

“In the standard run scenario, natural resources (for example oil, iron and chromium) become harder and harder to obtain. The diversion of more and more capital to extracting them leaves less for investment in industry, leading to industrial decline starting in about 2015. Around 2030, the world population peaks and begins to decrease as the death rate is driven upwards by lack of food and health services.”

Not all the model’s scenarios result in this outcome, but the majority of them “show industrial output declining in the 2020s and population declining in the 2030s. The researchers didn’t put precise dates on their projections. In fact, they deliberately left the timeline somewhat vague.”
