The global IEA Efficiency Policy Progress Index (EPPI) score in 2016 was 6.3 following strong progress from 2011 to 2015 - two-and-a-half times greater than during the previous decade. But the incremental EPPI score for 2016 was 0.6, a decline from the average increment of the previous five years of 0.7-1.0. This decline is the result of the slowdowns in policy coverage and strength discussed above.
The IEA EPPI combines coverage and strength of codes and standards into a single index for measuring overall policy progress. The EPPI covers seven energy end-uses: space cooling, space heating, appliances, water heating, industrial motors, lighting, LDVs and HDVs. The countries included in the EPPI account for two-thirds of global energy use.
