While there’s been a lot of discussion around climate change and just how much of climate change is a result of emissions, a new study shows that CO2 emissions fell in a number of countries that had policies in place for moving away from fossil fuel dependence. Though globally, emissions are on the rise, the study showed that there were 18 countries that saw a decline. Where there was stronger policy, there were sharper declines.

According to the CBC, “In a new study published in the journal Nature Climate Change, researchers suggest that countries that are turning to renewable energy sources and moving away from fossil fuels are making progress in reducing CO2 emissions.” As the CBC continues:

The study looked at emissions from between 2005 and 2015. Globally, CO2 was on the rise — about 2.2 per cent annually — but in 18 countries, their emissions saw a decline. These 18 account for 28 per cent of global emissions.

“We went in these 18 countries and looked at what policies they had in place … and we found that, in the countries where there’s more policy in place, the decreases in emissions were larger,” said Corinne Le Quéré, a Canadian professor of climate change science at the University of East Anglia in the U.K. “That suggests that the policies do work.”

But another contributing factor, they found, was that these countries were also using less energy overall. They might have more efficient heating systems, or more electric cars on the roads, for example.
