The London Energy and Greenhouse Gas Inventory (LEGGI) is updated on an annual basis. The data sources used for estimating London’s emissions are based on government statistics which are published with a two-year lag.

The latest available data for London’s emissions is 2017. This estimates that London’s emissions were 30.32 million tonnes of CO2e. The breakdown was as follows:

  • Domestic: 38%
  • Commercial & Industrial: 37%
  • Transport: 26%

The next LEGGI update will be published in the autumn of 2020 and will provide estimates for 2018.

The London Environment Strategy estimated that 0.5% of London’s emissions were attributable to the GLA group and we will be providing an update on GLA group emissions when we publish the LEGGI later this year.
