The London Energy and Greenhouse Gas Inventory (LEGGI) is an emissions inventory which quantifies greenhouse gas emissions released to the environment from activities in London. It also quantifies emissions removed through Land Use, Land Change and Forestry sector activities. It is produced on an annual basis to measure progress against the Mayor's emissions reduction targets for London. The inventory provides emissions in...

The LAEI 2019 is the latest version of the London Atmospheric Emissions Inventory and replaces previous versions of the inventory. Emissions estimates of key pollutants (NOx, PM10, PM2.5 and CO2) by source type are included for the base year 2019 and forecast years 2025 and 2030. Emissions for previous years 2013 and 2016 have also been revised, using the latest data...

The LAEI 2016 has been superseded. Click here for the full list of releases. Emissions estimates of key pollutants (NOx, PM10, PM2.5 and CO2) by source type are included for the base year 2016. Emissions for previous years 2010 and 2013 have also been recalculated, using the latest data sources (emission factors, activity data, ...) and methodology. Emissions projected...

The Climate Change Mitigation and Energy Annual Report 2013-14 data provides levels of CO2 emissions reductions achieved through direct Mayoral programmes, including RE:NEW, RE:FIT, new development and decentralised energy programmes. It is produced by the Greater London Authority, and it is intended that data is produced annually.

The Business Plan 2013/14 established for the first time a suite of GLA Key Performance Indicators (KPI) closely linked to Mayoral priorities. These statistics show KPI performance, together with targets, forecasts and traffic light ratings. There are two traffic light ratings for each KPI: First, a backward looking traffic light assessing performance to date. Green indicates that performance is meeting or...
