UK carbon dioxide emissions

In 2020 the coronavirus (COVID-19) pandemic and the resulting restrictions brought in across the UK had a major impact on various aspects of society and the economy and this has had a significant impact on greenhouse gas emissions in the UK over this period.

  • Carbon dioxide (CO2) emissions in the UK are provisionally estimated to have fallen by 10.7% in 2020 from 2019, to 326.1 million tons (Mt), and total greenhouse gas emissions by 8.9% to 414.1 million tons carbon dioxide equivalent (MtCO2e). Total greenhouse gas emissions were 48.8% lower than they were in 1990.

  • This large fall in 2020 is primarily due to the large reduction in the use of road transport during the nationwide lockdowns and the reduction in business activity.

CO2 emissions from transport fell 19.6% in 2020, accounting for over half of the overall fall from 2019, and in the business sector they fell by 8.7%. Conversely, CO2 emissions from the residential sector increased by 1.8% as more people stayed at home. CO2 emissions from the energy supply sector fell by 11.9% following lower demand during the pandemic and the continued reduction in fossil fuel use in power stations. UK territorial greenhouse gas emissions, 1990-2020

What you need to know about these statistics:

This publication provides provisional estimates of 2020 UK territorial greenhouse gas emissions, meaning emissions that occur within the UK’s borders. Emissions are presented in carbon dioxide equivalent units (CO2e) throughout this statistical release. These estimates give an early indication of emissions in 2020 and are subject to revision when final estimates are published in February 2022. They also include estimates of quarterly emissions and the impact on emissions of external temperature changes.

These high-level sectors are made up of several more detailed sectors, which follow the definitions set out by the Intergovernmental Panel on Climate Change (IPCC) and which are used in international reporting tables which are submitted to the United Nations Framework Convention on Climate Change (UNFCCC) every year. It is important to note that these figures are based on provisional energy data and are subject to change. The sectorial breakdown is given mainly for information, and is included in the publication for completeness, but sectorial estimates are more uncertain than the overall total. These estimates cover the Kyoto “basket” of seven gases: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydro fluorocarbons (HFC), per fluorocarbons (PFC), sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3). The last four gases are collectively referred to as fluorinated gases or F gases. In accordance with international reporting and carbon trading protocols, emissions from each of the gases is weighted by its global warming potential (GWP), so that total greenhouse gas emissions can be reported on a consistent basis. The GWP for each gas is defined as its warming influence relation to that of carbon dioxide over a 100-year period. Greenhouse gas emissions are then presented in carbon dioxide equivalent units (CO2e). Carbon dioxide is reported in terms of net emissions, which means total emissions minus total removals of carbon dioxide from the atmosphere by carbon sinks. Carbon sinks are defined by the UNFCCC as “any process, activity or mechanism which removes a greenhouse gas, an aerosol or a precursor of a greenhouse gas from the atmosphere”. The provisional estimates are not used for any formal reporting of how the UK is performing against its emissions reduction targets, as this requires final estimates based on the UK’s greenhouse gas inventory. However, these statistics give policy makers and other users an initial steer as to the trend in emissions between 2019 and 2020, which helps them to form an initial assessment of the extent to which the UK is on track to meet targets.

In 2020, the coronavirus (COVID-19) pandemic and the resulting restrictions brought in across the UK had a major impact on various aspects of UK society and the economy. There are a range of statistics available from across the UK government and the devolved administrations showing the impact it has had, including profound changes to travel and economic activity4,5. As a result, COVID-19 will have had a significant impact on greenhouse gas emissions in the UK in 2020, in particular from transport and from businesses, although it is not possible to identify the exact size of this effect as other factors will have also played a part in the changes seen during 2020. Territorial carbon dioxide emissions are provisionally estimated to have fallen by 10.7% (39.0 Mt) in 2020 from 2019, and total greenhouse gas emissions by 8.9% (40.7 MtCO2e). This is the largest proportional fall in UK greenhouse gas emissions in a single year since the start of the data series in 1990, slightly larger than the 8.6% fall seen in 2009 during the recession, although in absolute terms there were larger emission reductions in 2009 (of 56.1 MtCO2e) and 2011 (of 45.5 MtCO2e). At 414.1 MtCO2e, greenhouse gas emissions in the UK in 2020 were 48.8% lower than in 1990. Because these provisional estimates are based on energy data it is only possible to make estimates of carbon dioxide emissions from different source sectors and not estimates of other gases, so the rest of this section presents the trends in carbon dioxide emissions. Emissions were particularly reduced during the second quarter of 2020, from April to June, when carbon dioxide emissions fell by 24.6% from the same period the year before. This followed the nationwide lockdown that began on 23 March 2020, when many businesses were closed and people were instructed to stay at home as much as possible. Transport was particularly affected, with emissions falling by 43.9% compared to the same quarter the previous year, largely as a result of the large fall in the use of road transport6. During the second half of the year when there were fewer restrictions in place emissions did not fall to the same extent, with carbon dioxide emissions 8.0% lower than in the second half of 2019.

The combustion of fuel releases both energy and carbon dioxide. The amount of carbon dioxide released by the production of one unit of power depends on the type of fuel that is burned. For example, since coal has a higher carbon content than gas, more carbon dioxide emissions result from burning one ton of coal to generate a unit of power than from one ton of gas. Emissions per unit of electricity supplied from fossil fuels are estimated to have been around 400 tons of carbon dioxide per gigawatt hour (GWh) overall in 2020 in the UK. Within this, emissions from electricity generated from coal (1,010 tons of carbon dioxide per GWh electricity supplied) were over twice as high as for electricity supplied by gas (370 tons of carbon dioxide per GWh). For all sources of electricity (including nuclear, renewables and auto generation), the average amount of carbon dioxide emitted in 2020 amounted to 180 tons per GWh of electricity supplied. In 2020, total territorial carbon dioxide emissions from the use of fossil fuels, including fuel used for generating electricity, were estimated at 301.5 Mt. This was 11.3% lower than the 2019 figure of 339.8 Mt. The biggest change in emissions was from the use of petroleum, down 25.3 Mt (17.2%) from 146.7 Mt in 2019 to 121.4 Mt in 2020. This largely resulted from the reduction in road transport in the UK during the nationwide lockdown periods. Coal use also decreased, down 1.8 Mt (15.0%) in 2020, mostly due to the reduced use of coal for electricity generation. Over the period 1990 to 2020, carbon dioxide emissions from fossil fuels decreased by 46.4%. Over the same period, primary consumption of fossil fuels dropped by 36.2%. This relatively large decrease in emissions can be attributed to a large decrease in the use of coal accompanied by an increase in the use of gas. Territorial carbon dioxide emissions from gas as a proportion of all carbon dioxide emissions from fossil fuels has increased from 26.0% in 1990 to 56.4% in 2020, whilst emissions from coal as a proportion of all fossil fuel carbon dioxide emissions has decreased from 38.9% to 3.3% over the same period. Oil was responsible for 35.2% of carbon dioxide emissions from fossil fuels in 1990 and this has increased to 40.3% in 2020.
