Homi Kharas, Wolfgang Fengler, and Lukas Vashold at Brookings:
2023 will be the year with the highest emissions ever recorded, according to new projections from the World Emissions Clock put out by the nonprofit arm of World Data Lab. The world is expected to emit almost 59 Gigatons of carbon-equivalent greenhouse gases; about 2,000 tons per second. The global average citizen now emits around 7.4 tons of these emissions, which can be disaggregated into 2.7 tons for energy, 1.8 tons for industry, 1.5 tons for agricultural production and land-use change, 1 ton for transport, and 0.4 tons for heating and cooling buildings (see Figure 1). This trend of growing emissions means that current levels are now about one-third higher than the levels that would have limited global warming to 1.5 degrees had an appropriate global program been put in place in 2021. This means that per capita emissions need to come down to below 5t per capita over the next decade and move towards 2.5t by 2040.
