CO2 emissions decreased by 28% in 2018, falling back toward the 2015 level. Increases in nuclear and hydropower generation reduced reliance on fossil-fired thermal plants during the year. Total CO2 emissions resulting from own consumption were estimated at 3.47 million tonnes (-5.2% relative to 2017). These emissions are included in the carbon footprint assessments of the industrial sites in question.
