2030 CLIMATE CHALLENGE

The vast majority of GHG emissions come from a small set of countries and sectors. In fact, only 20 countries produce 75 percent of GHG emissions, and three-fourths of GHG emissions land in four energy sectors: electricity, transportation, buildings, and industry. Within the 20 countries, the United States has historically been the world's largest carbon dioxide emitter and currently has the second highest amount of emissions in the world. If the United States decarbonizes at scale in the next ten years (later for poorer countries, earlier for richer countries)-i.e. by 2030-then we have a chance to land at a decent future. Failure in the United States almost guarantees global failure.
