The London Energy and Greenhouse Gas Inventory (LEGGI) is an emission inventory which quantifies pollution releases to the environment. It also quantifies the pollutants removed through Land Use, Land Change and Forestry sector activities.

It is produced on an annual basis to measure progress against the Mayor's CO 2 e reduction targets for London. Since 2020 it is also used to meet the reporting requirements for the Global Covenant of Mayors for Climate and Energy (GCoM).

The 2018 LEGGI groups emissions and removals categories into five main sectors as defined by the Intergovernmental Panel on Climate Change (IPCC). These are:

I. Energy (Stationary energy, Transport energy)

II. Industrial processes and product use (IPPU)

III. Agriculture, forestry, and other land use (AFOLU)

IV. Waste

V. Other. 

The 2018 LEGGI estimates the quantity of the following greenhouse gases (GHGs):

  •  Carbon Dioxide (CO 2 ),
  •  Methane (CH 4 ),
  •  Nitrous Oxide (N 2 O),
  •  Hydrofluorocarbons (HFCs),
  •  Perfluorocarbons (PFCs),
  •  Nitrogen Trifluoride (NF 3 ),
  • Sulphur Hexafluoride (SF 6 ).

 Emission Factors (EFs) used to estimate greenhouse gas (GHG) emissions in London were obtained from BEIS, IPCC and other Emission Factors databases.

Publications of the LEGGI between 2000 and 2019 (reporting on 2017 emissions), reported for the two major emission sectors in London: Stationary Energy (homes and workplaces) and Transport.

The latest LEGGI (reporting 2018 emissions) now provides the emission estimates for the five major IPCC emission sectors in line with the latest international best practice. The results, capturing the five sectors, show that in 2018, London’s CO 2 e emissions were 32.4 million tonnes. This is a 29 per cent reduction on 1990 levels and a 37 per cent reduction since the peak of emissions in 2000. This is despite an ever-increasing population – an increase of nearly 30 per cent since 1990 and significant economic growth over that period. London’s per capita emissions have reduced by 45 per cent, from 6.6 MtCO 2 e in 1990 to 3.6 MtCO 2 e in 2018.

Emissions calculated using just the two major energy emissions sectors (as previously reported by LEGGI) show London’s CO 2 e emissions from stationary energy and transport were 28.84 million tonnes. This is a 35 per cent reduction on 1990 levels for those emissions sectors.
