Our global carbon budget to stay below 1.5°C global warming (from pre-industrial levels) ran out about 10 to 20 years ago, if we use the latest climate data and a reasonable likelihood of success to derive our climate targets.

To achieve a high likelihood of limiting warming to 1.5°C, this report recommends government decision makers revisit mitigation timelines, address barriers to an accelerated mitigation timeline, develop/implement a comprehensive carbon dioxide removal (CDR) strategy, and incorporate consumption-based GHG emissions in climate planning.
