The climate cost of 100% renewable energy
At the COP 21 in Paris, the international community agreed on an agenda to cut greenhouse gas emissions to a level that will limit the rise in average global temperatures to 1.5°C. On 5 October 2016, the threshold for entry into force of the Paris Agreement was achieved. For a likely chance to stay below a rise of 1.5C, we have to reach zero emissions by 2050.
