In December 2015 in Paris, leaders of 195 countries agreed to reduce carbon emissions by developing voluntary national emission-reduction plans by 2020. Global leaders signed the agreements at the UN in April 2016. The Paris agreement becomes effective when 55 countries representing 55 percent of global greenhouse gas emissions ratify it.
Country plans are expected to reduce emissions as clean technology improves, so that after 2050 there will be fewer carbon-emitting activities than in 2015. Wind turbines and solar panels supplied about 10 percent of the world's electricity in 2015.
