World must cut 37gt CO₂ by 2050 – Irena

Agency report identifies key technologies and actions needed to be consistent with 1.5°C pathway

The world must cut 37gt of annual CO₂ emissions by 2050 to keep to a pathway that would limit global warming to 1.5°C this century, according to the International Renewable Energy Agency (Irena). Around 9.25gt of these cuts must come from energy efficiency, 9.25gt from renewables, 7.4gt from electrification, 3.7gt from hydrogen, 2.2gt from carbon capture and storage (CCS), and 5.2gt from biomass equipped with CCS, according to the body’s World Energy Transitions Outlook, published today. “[The report] charts the fastest path to emissions reduction consistent with the 1.5°C goal. It prioritises existing solutions and those with the most chance of becoming viable in the coming years,” says Ire
