A Union of Concerned Scientists letter, citing Banking on Climate Chaos, calls Citi the second-largest fossil-fuel financier since the Paris Agreement. Citi publishes financed emissions for ten sectors but no portfolio-wide total, and has set no facilitated-emissions targets. Its operational emissions fell on a location basis but rose on a market basis, and it left the Net-Zero Banking Alliance at the end of 2024 while saying it remains committed to net zero.
