Emissions of the powerful greenhouse gas insulating gas are rising

A recent study suggests that the UK’s use of Sulfr hexafluoride has risen in recent years, and leakage levels are over 1%. It is estimated that, by 2100, appropriate controls could limit the contribution of insulating gas to global warming to 0.2%. In the UK, the gas already contributes this much to its annual global warming potential.

Net zero and the different official measures of the UK's

Background. The UK government announced a target of net zero for UK greenhouse gas (GHG) emissions by 2050 following recommendations made by the Committee on Climate Change. Net zero can be achieved by emission reduction and removal. Net zero means that the UK’s total greenhouse gas (GHG) emissions would be equal to or less than the emissions the UK removed from the environment1. Measuring the UK’s progress to net zero. Estimates of the UK’s greenhouse gas (GHG) emissions, published by the Department for Business, Energy and Industrial Strategy (BEIS), are used as the baseline for monitoring the Climate Change Act net zero target. Other official measures of the UK’s greenhouse gas emissions. The UK is required to report its estimated greenhouse gas (GHG) emissions on a range of different bases in order to fulfil a wide range of international agreements.

Net Zero - The UKcontribution to stopping global warming

The Committee on Climate Change recommends a new emissions target for the UK: net-zero greenhouse gases by 2050. In Scotland, we recommend a net-zero date of 2045, reflecting Scotland’s greater relative capacity to remove emissions than the UK as a whole. In Wales, we recommend a 95% reduction in greenhouse gases by 2050.

Analysis: Why the UK’s CO2 emissions have fallen 38% since

The Big PictureAnalysing Emission ReductionsElectricity GenerationTransportationBusiness, Residential and Other CO2 SourcesEmissions Embodied in TradeConclusionsMethodologyUK emissions have declined from around 600m tonnes of CO2 (MtCO2) in 1990 to 367MtCO2 in 2017. If underlying factors driving emissions had not changed, Carbon Brief’s analysis shows that a growing population and a constant electricity generation mix would have led to emissions increasing by around 25% compared to 1990 levels. Instead, emissions actually fell by 38% to 367MtCO2, as shown in the black area in the figure below. Each coloured wedge in the figure shows one factor contributing to this decline. As the chart shows, no single factor was responsible for more than around a third of the total reduction in the UK’s CO2. Overall, emissions in 2017 were 51% lower than they would have been without these changes Decreases in CO2 emissions from electricity production is one of the main drivers economy-wide (dark blue wedge), accounting for around 36% of the total emissions reduction in 2017.
