New paper out: Multiple pathways towards sustainable development goals and climate targets

A new study led by Bjoern Soergel (Potsdam Institute for Climate Impact Research) presents three different sustainable development pathways, all of which avoid dangerous climate change and enable substantial progress towards the UN Sustainable Development Goals (SDGs). The scenarios were quantified by four different modelling teams participating in the SHAPE project, comprising two “full-system” integrated assessment models and two sectoral models specialised on the global buildings sector and the required construction materials. The study shows that different pathways towards the SDGs are possible, but all of them have their respective strengths and weaknesses. For example, one of the scenarios (“Resilient Communities”) envisions strong lifestyle changes and a transition to a post-growth economy for high-income countries. This scenario has the lowest warming and the strongest improvements in biodiversity, but the underlying assumptions on lifestyle change might be challenging to adopt. On the other hand, a scenario envisioning green-tech innovation and continued economic growth has a much lower reliance on lifestyle changes, but features technologies unproven to work at scale, such as carbon capture and storage.
