London Energy and Greenhouse Gas Inventory (LEGGI)
Greater London Authority (GLA)
Updated 6 months ago
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...
Ultra Low Emissions Zone 2019
Greater London Authority (GLA)
Updated over 2 years ago
The central London Ultra Low Emission Zone (ULEZ) was introduced to clean up London’s most polluted air. It started on 8 April 2019, operates in the existing central London Congestion Charge Zone, 24 hours a day, every day of the year. Vehicles must meet strict emission standards to drive in the central London ULEZ area, or pay a charge. It...

Greater London Authority (GLA)
Updated over 2 years ago
The Ultra Low Emission Zone will be expanded from the 25 October 2021 to include the area up to the North and South circular roads (from the Congestion Zone). ULEZ was introduced to clean up London’s most polluted air. It started on 8 April 2019, operates in the existing central London Congestion Charge Zone, 24 hours a day, every day...
Low Emission Zone
Greater London Authority (GLA)
Updated almost 7 years ago
The Londonwide Low Emission Zone (LEZ) was launched in February 2008. The LEZ operates to encourage the most polluting heavy (including buses, coaches, lorries and other specialist vehicles) diesel vehicles driving in London to become cleaner. The LEZ covers most of Greater London and is in operation 24 hours a day, every day of the year. Heavy vehicles must meet...

London Atmospheric Emissions Inventory (LAEI) 2010 Air Quality Focus Areas
Greater London Authority (GLA)
Updated about 8 years ago
The LAEI 2010 has since been superseded. Click here for the full list of releases. There are 187 Air Quality Focus Areas in the Capital. These are locations that not only exceed the EU annual mean limit value for NO2 but are also locations with high human exposure. The Focus Areas were defined to address concerns raised by boroughs within...
Analysing Air Pollution Exposure in London
Greater London Authority (GLA)
Updated about 9 years ago
Updated in Februrary 2017.Air quality in London has improved in recent years as a result of policies to reduce emissions, primarily from road transport. However, recently updated maps of pollution concentrations for 2013 (LAEI 2013) still show significant areas of exceedances of the annual mean NO2 EU Limit Values. Improvements are planned to address these, as recently announced in the...
