The share of world final energy use covered by policies that mandate energy efficiency improvements grew to nearly 32% in 2016 – an increase of 1.4 percentage points on 2015, but still leaving 68% of global energy use uncovered.
In stark contrast with previous years, nearly all the 2016 increase in coverage was due to the continuing impact of existing policies, as old energy-using equipment was replaced. Just 1% of the increase was due to new policies, an historic low. This is the slowest policy progress since 2009.
