One of the most promising areas of potential progress is on electrification, which is needed to reduce global greenhouse gas emissions. Despite the strong growth in renewable energy around the world, nearly 80% of primary energy still comes from fossil fuels, used for transport, heating and industrial purposes. Adopting electric vehicles, heat pumps, batteries and other low-carbon electric technologies could halve global primary energy needs, because they are so much more efficient than using fossil fuels. Thornier issues of equity and climate justice will also come to the fore, including work on a “just transition” mechanism to help workers in high-carbon industries adjust to low-carbon jobs, and the vexed issue of climate finance for developing countries from the rich. Poor countries are angry that many developed nations are slashing their aid budgets, including money for climate finance, and a promise to triple the funds available for helping them adapt to extreme weather has yet to
