Légère augmentation des émissions de gaz fluorés en 2013 au Royaume-Uni (en anglais)

Un nouveau rapport fournit les dernières estimations provisoires de 2013 des émissions de gaz à effet de serre par source et les estimations finales de 2012 des émissions de gaz à effet de serre par type de carburant et d'utilisateur final au Royaume-Uni .
The latest report of the UK Department of Energy & Climate Change provides the latest provisional estimates of 2013 UK greenhouse gas emissions by source, and final estimates of 2012 UK greenhouse gas emissions by fuel type and end-user.

In 2013, UK emissions of the basket of six greenhouse gases covered by the Kyoto Protocol were provisionally estimated to be 569.9 million tonnes carbon dioxide equivalent (MtCO2e). This was 1.9% lower than the 2012 figure of 581.1 million tonnes.

In 2013, UK net emissions of carbon dioxide, including removals from the atmosphere by carbon sinks, were provisionally estimated to be 464.3 million tonnes (Mt). This was 2.1% lower than the 2012 figure of 474.1Mt. CO2 is the main greenhouse gas, accounting for 82% of total UK greenhouse gas emissions in 2012. Since 1990, UK carbon dioxide emissions have decreased by around 21%. This fall in emissions has coincided with a decrease in overall energy consumption over the period.

HFC emissions accounted for 14.1 MtCO2e, or 2.4% of total greenhouse gas emissions (577.5 MtCO2e) in 2012.

The largest decrease between 2012 emissions and provisional 2013 emissions was a 7.5% (14.5 MtCO2e) decrease in the energy supply sector, due to a decrease in fossil fuel use for electricity generation.

The business sector was responsible for the majority of emissions from F-gases. While there was an overall 31% decrease in greenhouse gas end-user emissions from the business sector between 1990 and 2011 emissions from F-gases increased significantly.

Mainly due to air conditioning and refrigeration, emissions grew from 0.6 MtCO2e in 1990 to 12.4 MtCO2e in 2012. However, the main rise was between 1990 and 2010. Since 2010, emissions have risen by just 0.4 MtCO2e.
