This dataset includes the locations and species information for over 1,100,000 of London's public realm trees. It also includes additional information such as size and age for some of these trees. These are predominantly street trees and trees in parks and open spaces, but the dataset also includes some trees found in school grounds and on publicly maintained housing land. The...

The London Building Stock Model v2 provides energy efficiency data for all London homes. This includes information on EPC ratings, heating systems, insulation levels and building fabric. This dataset represents an update of the original London Building Stock Model, and it brings together data from Energy Performance Certificates (EPCs), alongside data from other sources such as the London borough councils and...

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 Mayor is committed to cutting fuel poverty and increasing the energy efficiency of buildings across London. To help target where action is most needed, the Mayor has developed a London Building Stock Model with the UCL Energy Institute. The London Building Stock Model is a database of all the energy and carbon data collected through the Mayor’s energy programmes and...

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 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).

This is the first natural capital account for London, and was supported by the Mayor of London, the National Trust and the Heritage Lottery Fund. The natural capital account assesses the economic value of different benefits that London and Londoners gain from the city’s public parks and other green spaces. For more information on the methodology and results of this analysis, please see the London.gov.uk website.

This report contains an introduction to PM2.5­, summarises our current understanding of PM2.5 concentrations and exposure, discusses the findings of research undertaken by the GLA and TfL into the extent of PM2.5 pollution in London, and assesses the potential for meeting World Health Organisation guidelines by 2030. Our analysis found that at present all Londoners are exposed to concentrations higher...

Data for London air quality monitoring sites showing whether annual monitoring objectives were met for different species of pollutant. Data for 2016 includes the first two months of the year only so this is an indicative outlook. This data was accessed using the London Air API. For some species, all monitoring sites taking measurements have met the monitoring objectives over the...
