The US catapulted itself to the top of countries with the most ambitious climate targets this week after President Joe Biden announced the US will cut its economy-wide greenhouse gas emissions (GHG) at least 50% below 2005 levels by 2030.

To compare countriesโ€™ ambitions on an apples-to-apples basis, Victoria Cuming, head of global policy at BloombergNEF, crunched the numbers on climate pledges by G20 countries. She found the US goal ranks among most ambitious targets relative to the countryโ€™s โ€œbusiness as usualโ€ emissions trajectory.ย  US emissions are about 20% below 2005 levels today, a figure likely to inch up during the economic recovery after the pandemic. That means the US will likely experience the most rapid economic and social change among major GHG emitters as a result of decarbonization over the next decade.

But other countries are setting the bar even higher when assessing their progress toward net-zero, Cuming concluded. In terms of absolute and per-capita emissions, the UK steals the show. In this sense, the US has plenty of catching up to do. GHG emissions per capita in the US remain among the highest in the world and will likely remain high even if the 2030 target is met.
