Citigroup continued with disposals in 2025, selling its retail business in Poland, completing its exit of all operations in Russia and reducing its stake in Banamex of Mexico, a process that subsequently has been all but completed in 2026.
The finance giant's 2025 rose 6 percent tear over year to $84.2 billion but employee numbers, spread across more than 90 countries, fell 10,000 to 219,000.
Emissions resulting from business travel by Citigroup fell from about 75,000 metric tons of carbon dioxide equivalent in 2023 to 69,400 in 2024 and to 55,400 in 2025. Figures for 2023 and 2024 were restated following the separation of Banamex from the rest of Citigroup’s operations.
Rail travel emissions also fell, from 117 metric tons in 2023 to 81 in 2024 and 76 in 2025.
Citigroup prioritizes the use of video- and webconferencing technologies when possible and encourages colleagues to consider rail travel as an alternative to short-haul flights. It also offers electric vehicle rentals and rides shares as a reimbursable expense.
