As the world strives to cut greenhouse gas emissions and limit climate change, it is crucial to track progress towards globally agreed climate goals. For a decade, UNEP’s Emissions Gap Report has compared where greenhouse gas emissions are heading against where they need to be, and highlighted the best ways to close the gap. 1. Introduction -- 2. Global emissions trends and G20 status and outlook -- 3. The emissions gap -- 4. Bridging the gap: Enhancing mitigation ambition and action at G20 level and globally -- 5. Bridging the gap: Transformations towards zero-carbon development pathways -- 6. Bridging the gap: Global transformation of the energy system -- 7. Bridging the gap: Enhancing material efficiency in residential buildings and cars
