6 Difference in Emissions Projections MtC SHCS NAEI /06

7 Residential Sector Emission change from 1990 SHCS 20% reduction in total emissions NAEI 11% reduction in total emissions NAEI 4% reduction in direct emissions

8 Change at dwelling level Mean total emissions per dwelling has reduced from to 6.6 (40% reduction since 1990) True across all dwelling types However residential stock has increased by 25% (1.88 to 2.34 million dwellings) New buildings have lower emissions but they still have a carbon impact.

10 Where are we now - Impact of SHQS If all social housing stock is upgraded to meet the SHQS energy criteria then SHCS estimates: Energy reduced (GJ) by 14% C02 reduced by 13% Corresponding energy efficiency ratings would be 7 now, 8 if brought up to SHQS Once these upgrades are in place the mean CO2 emissions will be 3.9t which reflects a 53% decrease in emissions since 1990 (using the mean as baseline)
