The global economy is relying less on carbon to power it.
And the numbers look promising for the environment. In 2015, global carbon intensity fell by 2.8 percent — a record drop and more than double how much it fell between 2000 and 2014 on average.
But that's not nearly enough to keep global warming below 2 degrees Celsius — the number agreed upon in the Paris climate agreement.
One of the biggest reasons for the decline is China — the country that consumes half of all the coal produced. In 2015, it cut coal use dramatically.
The U.K. and the U.S. round out the top three countries that managed to lower their carbon intensity.
While the reduction in coal is good news for carbon emissions, the director of sustainability and climate change at PwC told Climate Home that coal is "low-hanging fruit" in the fight to reduce carbon emissions. It will likely be tougher to push other industries to reduce emissions.
