The Climate Change Mitigation and Energy Annual Report 2009-2012 data provides levels of CO2 emissions reductions achieved through direct Mayoral programmes, including RE:NEW, RE:FIT, and the Decentralised Energy Programme. It is produced by the Greater London Authority and this forms the first set of data. It is intended that data is produced annually.

Listing of low carbon energy generators installed on GLA group properties as requested in question 2816/2010 to the Mayor during the September 2010 Mayor's Question Time. To date information has been provided by the London Fire and Emergency Planning Authority, the GLA and the Metropolitan Police Service (MPS). Transport for London has provided interim data, and further data will follow. GLA csv LFEPA csv MPS csv TfL csv LFEPA DataDetails of low carbon energy generators located at fire stations in London operated by the London Fire Brigade (London Fire and Emergency Planning Authority). The data provides the location of the fire stations (including post code) and the type of generators at those premises including photovoltaic (PV) array, combined heat and power (CHP), wind turbines (WT) and solar thermal panels (STU). Data correct as of June 2016. The previous LFEPA data from October 2010 is available in csv, tab and shp formats. Previous LFEPA data from May 2011, April 2014 and April 2015 is available. For further information please contact david.wyatt@london-fire.gov.uk GLA Data Details of the photovoltaic (PV) installation at City Hall. Data correct as of 4th May 2011. MPS Data The table provides details of low carbon energy generation installations on MPS buildings in London. The data provides the site locations (including post code, grid reference and latitude/longitude) and the type of generators at those premises which includes Photovoltaic (PV) arrays, Combined Heat and Power (CHP), Ground Source Heat Pumps (GSHP) and Solar Thermal panels (STU). This data is correct as at the 20th May 2011. TfL Data Details of low carbon energy generators located at Transport for London’s buildings such as stations, depots, crew accommodation and head offices are provided. The data includes the postcode of the buildings and the type of generators at those premises including photovoltaic (PV) array, combined heat and power (CHP), wind turbines (WT) and solar thermal panels (STU). Data correct as of 24th May 2011. For further information please contact helenwoolston@tfl.gov.uk

Data analysis to support the London Decentralised Energy Capacity Study The London Decentralised Energy Capacity Study presents the findings of a regional assessment of the potential for renewable and low carbon energy in Greater London and has been conducted by the Greater London Authority (GLA), with funding from the Department for Energy and Climate Change (DECC). The overall approach is based on a standardised methodology developed for DECC (referred to as the 'DECC methodology') which has been modified to reflect Greater London's urban nature (the tailored methodology). An assessment of the technical potential and deployment potential is made in Phases 1 and 2 of the study respectively, whilst Phase 3 considers a roadmap to deployment. The accompanying reports are available on the GLA website _Data Download_ The datasets consist of a series of Excel 2003 spreadsheets which outline the methodology and parameters used, along with detailed and summary results. The datasets for each phase are contained in a compressed file and should be used in conjunction with the reports. Note that some workbooks contain macros but these are not required for them to work so can be disabled on opening. Phase 1 zip (31mb) Phase 2 zip (19mb) Phase 3 zip (17kb)

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 following five categories: I. Stationary Energy II. Transport III. Waste IV. Industrial processes and product use (IPPU) V. Agriculture, forestry, and other land use (AFOLU) Publications earlier than the 2018 LEGGI only included emissions in the first two of these categories. However, LEGGI now provides estimates of these additional sectors for earlier years. The coronavirus (COVID-19) pandemic and the resulting restrictions introduced in 2020 across London and the UK had major impacts on various aspects of society and the economy, which had a significant impact on greenhouse gas emissions. 2020 statistics should therefore be cited with caution. In 2022, London’s emissions were 28.40 million tonnes (MtCO 2 e). Over the short-term, emissions went down from 31.94 MtCO 2 e in 2019 (pre-pandemic), to 28.37MtCO 2 e in 2021 and then in 2022 there was a very small ‘pandemic rebound effect’ as emissions increased to 28.40 MtCO 2 e. Over the longer term, emissions are 37 per cent lower than 1990 levels and 44 per cent below the peak of emissions in 2000. Despite a 30 per cent increase in population since 1990 and significant economic growth over that period, London’s per capita emissions have reduced by 52 per cent, from 6.7 tCO 2 e in 1990 to 3.2 tCO 2 e in 2022. Compared to the rest of the UK, London has the lowest per capita emissions of any region.

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).
