Transport is the largest source of our city’s total emissions (56%) followed by stationary energy such as electricity and natural gas use in buildings (28%). To achieve our city’s 2030 emissions reduction target, we need to make significant reductions in these two key emissions sources over the next 7 years by changing how we live and move around the city.
