After the release of the latest Intergovernmental Panel on Climate Change (IPCC) report released in April 2022, scientists say the “time for climate action is now” whereby there is still opportunity to halve emissions by 2030. In 2010-2019 average annual global greenhouse gas emissions were at their highest levels in human history, but the rate of growth has slowed. Without immediate and deep emissions reductions across all sectors, limiting global warming to 1.5°C is beyond reach. However, there is increasing evidence of climate action, since 2010, there have been sustained decreases of up to 85% in the costs of solar and wind energy, and batteries. An increasing range of policies and laws have enhanced energy efficiency, reduced rates of deforestation and accelerated the deployment of renewable energy.
We are at a crossroads. The decisions we make now can secure a liveable future. We have the tools and know-how required to limit warming
I am encouraged by climate action being taken in many countries. There are policies, regulations and market instruments that are proving effective. If these are scaled up and applied more widely and equitably, they can support deep emissions reductions and stimulate innovation. – IPCC Chair Hoesung Lee
