This is a new tool to help decision-makers choose which locations within London might be prioritised for tree planting. This tool presents the Curio Canopy – London Tree Canopy Cover map at ward scale[1], alongside several other environmental and social datasets. There are multiple factors that influence both the existing variation in tree canopy cover across the capital, and the potential...

This study estimates the long-term health impacts of exposure to air pollution in London from 2016 to 2050. The study finds that by 2050 policies in the London Environment Strategy (including the central London Ultra Low Emission Zone and expansion to the North and South circular roads) will result in: almost 300,000 Londoners avoiding new diseases attributable to air pollution,...

Two Google Street View cars, equipped with reference-type air quality monitors, are measuring air pollution over approximately 600 eight-hour shifts between autumn 2018 and autumn 2019. The cars use fast-response, research-grade instruments to precisely measure pollution concentrations approximately every 1-10 seconds. Pollutants measured include black carbon (BC), CO₂, NO, NO₂, O3, PM2.5 (and other PM size ranges) on a variety...

The Breathe London stationary network is made up of 100 AQMesh pods, each containing a collection of small sensor-based air quality monitors that offer near real-time localised air quality information. They measure nitrogen dioxide (NO₂) and nitric oxide (NO) using electrochemical sensors; particulate matter (PM) in various size cuts (PM₂.₅ and PM10 are reported) using a light-scattering optical particle counter; and carbon dioxide...

These ward level well being scores present a combined measure of well-being indicators of the resident population based on 12 different indicators. Where possible each indicator score is compared with the England and Wales average, which is zero. Scores over 0 indicate a higher probability that the population on average will experience better well-being according to these measures. Users can adjust...

The Green Infrastructure Focus Map is a new tool and evidence base to help London’s decision-makers identify where green infrastructure improvements and investments might be best targeted, and what kind of interventions might be most useful for the needs of a specific area. The Green Infrastructure Focus Map can help: identify where there is more need or less...

These datasets accompany the London Secondary Heat Study (2013) and provides an understanding of the technical potential (available heat) and deployment potential (delivered heat) of eleven key secondary heat sources in London. The accompanying reports are available on the GLA website. Data available for Middle Super Output Areas (MSOA).

Focus on London 2009 Packed with interesting information about our capital city, the Focus on London (FoL) report offers a unique snapshot of life in London. The report is produced by the GLA's statistical department, Data Management Analysis Group (DMAG) in partnership with the London Development Agency, Office for National Statistics, London Health Observatory, Met Police, London Ambulance Service and London Fire...

The Mayor has a role to play in leading, shaping and responding to changes in London through the work of the GLA group. Inclusive London: the Mayor's equality, diversity and inclusion strategy sets out how he will help address the inequalities, barriers and discrimination experienced by groups protected by the Equality Act 2010, as well as wider issues. These include...

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...
