Both scenarios envisage a 23% reduction in greenhouse gas emissions by 2050 in the WEM scenario and a 72% reduction in the WAM scenario compared to 1990 levels. The largest percentage of emissions come from the energy sector, a 72% reduction could occur if in this sector achieve a reduction of 64% in 2050, compared to 1990. These projections do not propose measures to reduce greenhouse gas emissions in the IPPU sector, so the forecasts are taken according to the basic regression model, which by 2050 compared to 1990 is expected to increase of greenhouse gases by 153%.
