Understanding Carbon

• We really mean Greenhouse Gases

• ‘Direct’ carbon dioxide emissions - 8.8 t/person/yr

• Greenhouse gas footprint – 16.3 t/person/yr

Understanding Carbon

• We usually place too much importance on ‘buildings’, by as much as 86%

• A lot of what we attribute to buildings are not really building emissions, eg

- the appliances people put in buildings- infrastructure between buildings
