About Fugitive Emissions
Fugitive emissions are accidental emissions from human activities
In the UK, methane, nitrous oxide and flourinated gases are the largest contributors to global warming after CO2. Methane is a powerful greenhouse gas, with a global warming potential 27 times that of CO2. The importance of reducing methane emissions to mitigate climate change was recognised at COP26 where the Global Methane Pledge was launched, 150 countries have since committed to reducing methane emissions by 30% by 2030. Methane’s short life in the atmosphere means that efforts to reduce emissions can bring much needed rapid benefits for climate change.
After CO2, methane, nitrous oxide and fluorinated gas emissions have the largest share of UK GHG emissions.
The largest sources of fugitive methane are now waste and agriculture
Fugitive methane emissions in the oil and gas sector are widely publicised, but methane is also emitted from a range of other man made processes: Agriculture and waste are now the largest sources in the UK. Key emitters in these sectors are livestock farming, manure management and enteric fermentation, landfill and waste water treatment.
Nitrous Oxide has a global warming potential 273 times larger than CO2
Nitrous Oxide (N2O) is mainly emitted from agricultural soil management activities, where emissions are closely related to fertiliser application and soil management practices. N2O is also emitted from waste water processing, manure management, fossil fuel combustion and land management. Fluorinated gases are man made substances used in industry, for example refrigerants and chemicals used in semiconductor production
