According to the U.N.’s 1.5°C report, the world’s countries emitting the largest amounts of carbon dioxide have to turn things around soon: To limit warming to 1.5°C, global net greenhouse gas emissions from human activity must decline by about 45 percent from 2010 levels by 2030, and reach net zero by 2050. To limit warming to 2°C, emissions must decline by about 25 percent by 2030 and reach net zero by about 2070. Despite the great challenge ahead, IEA chief Fatih Birol remarked recently that clean energy investments can still “shift the world on to a pathway to net-zero emissions by 2050.” The path “is narrow but still achievable,” he said, “if we act now.” This story originally appeared in Yale Climate Connections.
