The Intergovernmental Panel on Climate Change (IPCC) has made it clear: the time for action is now. In its 2022 report on mitigation of climate change, scientists warn that unless the world takes immediate and deep cuts in emissions, the goal of limiting global warming to 1.5°C will slip permanently out of reach.

Average annual greenhouse gas emissions from 2010–2019 were the highest in human history. Yet, there is hope: climate action is expanding, technologies are advancing, and costs of clean energy are plummeting.
