It's happening throughout Europe and North America. The United States has had declining per-capita carbon consumption since around 1970. Absolute levels, which include population growth, have been going down since around 2000. We're replacing high-carbon power sources (i.e. coal) with lower carbon power sources (i.e. nat gas) and carbon-based sources with renewable sources, with wind and solar now producing some 13% of the total energy consumption and 20% of domestic energy production, more than double the percentages from 2015.
