Understanding what carbon footprint is and the impact of different greenhouse gas emissions on our environment is crucial for effective climate change mitigation. This detailed analysis focuses on the carbon footprint comparison of UK greenhouse gas (GHG) emissions, providing insights into various metrics used to measure and reduce emissions.
Greenhouse Gas Emissions: Three Primary Measures
The UK monitors greenhouse gas emissions through three primary measures: territorial, residence (production), and footprint (consumption). Each measure measured here provides a unique perspective on the UK’s carbon footprint and helps formulate strategies to mitigate global warming.
Territorial Emissions
Territorial emissions account for GHGs produced within the UK’s geographical borders. These include:
- Industrial Emissions: From Manufacturing and Energy Production within the UK.
- Domestic Emissions: From Residential Heating and T<Fransport within the country.
In 2023, average territorial emissions were estimated at an average of 384 million tonnes of carbon dioxide equivalents (Mt CO₂e).
Residence (Production) Emissions
Residence-based emissions cover GHGs produced by UK residents and businesses, both domestically and abroad. These include:
- Aviation and Shipping: Emissions from UK-operated flights and shipping activities.
- Tourism: Emissions generated by UK tourists abroad.
In 2022, these emissions were 512 Mt CO₂e.
Footprint (Consumption) Emissions
Footprint emissions encompass all GHGs from goods and services consumed in the UK, including imports. These include:
- Imported Goods: Emissions embedded in products imported into the UK.
- Domestic Consumption: Emissions from the use of these products by UK residents.
In 2020, estimates of the carbon footprinting from emissions were estimated at 582 Mt CO₂e.
How the UK Measures Greenhouse Gas Emissions
Territorial Emissions
Territorial emissions are used to monitor UK-wide emissions targets and are published by the Department for Energy Security and Net Zero (DESNZ). These emissions include those produced within the UK’s geographical boundaries from businesses, residents, and visitors, but exclude international aviation and shipping, some domestic flights, and UK residents and businesses abroad.
Key Targets:
- Achieving net-zero GHG emissions by 2050.
- Reducing emissions to 965 million tonnes of CO₂e between 2033-2037 under the sixth Carbon Budget.
Territorial emissions data are produced by countries following international guidelines from the Intergovernmental Panel on Climate Change (IPCC) and are reported annually to the United Nations Framework Convention on Climate Change (UNFCCC).
Residence (Production) Emissions
Residence-based emissions data, published by the Office for National Statistics (ONS), cover emissions from UK residents and businesses, both within the UK and overseas. They exclude emissions from foreign tourists and businesses operating within the UK.
Key Uses:
- Comparing emissions by sector of UK industry and households with economic indicators like Gross Value Added (GVA).
- Aligning with the UN System of Environmental-Economic Accounting (SEEA) for international comparisons.
Residence-based gasoline emissions are categorized as Scope 1 emissions, which include direct emissions from owned or controlled fuel sources.
Footprint (Consumption) Emissions
Footprint emissions, published by the Department for Environment, Food and Rural Affairs (Defra), encompass all GHG emissions throughout the supply chain of goods and services consumed in the UK, regardless of their production location.
Key Points:
- Include emissions from imported goods and exclude emissions from UK exports.
- Provide insights into the UK’s global contribution to GHG emissions through consumption.
Footprint emissions cover Scopes 1, 2, and 3, which include direct emissions, indirect emissions from purchased and energy use, other gases and all other indirect emissions from the production and transport of goods and services.
Comparing the Three Emissions Measures
In 2020, the emissions measures were:
- Territorial: 404 Mt CO₂e
- Residence: 489 Mt CO₂e
- Footprint: 582 Mt CO₂e
All three measures have shown a decline since 1990, with one quarter the most significant reductions observed in territorial emissions due to the UK’s transition from a manufacturing-based economy to a service-oriented one, increasing dependence on imports.
