The reader might thus believe that this is an absolute increase over the baseline, i.e. the situation where no policy of any kind would be enacted. When the emission constraint is imposed, power production by lignite power (the "dirtiest technolog/') decreases by 41% if no additional green quota is in place. When a green quota is introduced at 23% of total electricity, output from lignite power plants also decreases, but by only 31%.
