Climate Change, Energy Policy and Sustainability event series: Green growth, degrowth or agrowth?

Date 5 October 2026
Time 1 - 2pm
Location 309 Regent Street

The Climate Change, Energy Policy and Sustainability Research Group brings together colleagues and external speakers to discuss current research and developments in climate, energy and sustainability. This semester’s event series addresses a range of contemporary challenges, including energy insecurity, debates over economic growth and sustainability, international climate negotiations, and the geopolitics of critical mineral supply chains.

Should we ‘degrow’ the economy? I argue that this would not be a sensible approach for addressing ecological problems. Measures such as GDP or material throughput are not good indicators for environmental impact. Instead, we should use a constrained optimisation approach. Production output is to be maximised, but within ecological constraints such as a cap on carbon emissions. I also consider whether sufficiently stringent constraints would inevitably lead to some form of degrowth. Here we should carefully differentiate between different outputs. While some, such as local cultural performances or rail travel, can be scaled within ecological constraints, for others, such as air travel, this is more difficult or impossible. Technological possibilities can also change over time. While degrowth is often seen as a path towards a steady-state economy, I argue that production within ecological constraints can be expanded with the availability of new technologies. I conclude that we should adopt an agrowth approach, which constrains environmental impact irrespective of whether other economic measures grow.
