As growing climate change impacts are experienced across the globe, the message that greenhouse gas emissions must fall is unambiguous. Yet the Emissions Gap Report 2022: The Closing Window – Climate crisis calls for rapid transformation of societies finds that the international community is falling far short of the Paris goals, with no credible pathway to 1.5°C in place. Only an urgent system-wide transformation can avoid climate disaster.
The report shows that updated national pledges since COP26 – held in 2021 in Glasgow, UK – make a negligible difference to predicted 2030 emissions and that we are far from the Paris Agreement goal of limiting global warming to well below 2°C, preferably 1.5°C. Policies currently in place point to a 2.8°C temperature rise by the end of the century. Implementation of the current pledges will only reduce this to a 2.4-2.6°C temperature rise by the end of the century, for conditional and unconditional pledges respectively.
The report finds that only an urgent system-wide transformation can deliver the enormous cuts needed to limit greenhouse gas emissions by 2030: 45 per cent compared with projections based on policies currently in place to get on track to 1.5°C and 30 per cent for 2°C. This report provides an in-depth exploration of how to deliver this transformation, looking at the required actions in the electricity supply, industry, transport and buildings sectors, and the food and financial systems.
