To meet that goal, countries and companies have committed to reaching net-zero emissions of CO2 and reducing emissions of other greenhouse gases. But there has not been enough progress. The share of primary energy produced by renewable sources, for example, has risen slowly, from 8 percent in 2010 to 12 percent in 2021. If emissions stay on their current trajectory, estimates from various sources suggest, net zero would not arrive even by the end of the century. — A successful net-zero transition wil...
