L'Unione europea ha ridotto i gas a effetto serra del 23 per cento a partire dal 1990, la seconda più grande riduzione di emissioni dopo quella della Russia. È quanto emerge dal rapporto Eurostat secondo cui Mosca avrebbe tagliato del 29% le proprie emissioni in base ai dati riferiti al 2014. Secondo il rapporto dal titolo “Lo sviluppo sostenibile: uno sguardo all'Unione europea”, l'Ue è riuscita a ridurre le emissioni di gas serra in gran parte riducendo la fornitura e l'uso di energia. Altri paesi industrializzati come l'Australia, la Nuova Zelanda, il Canada, il Giappone e gli Stati Uniti hanno aumentato le loro emissioni di gas serra nello stesso periodo.

The European Union has reduced its greenhouse gas (GHG) emissions by 23 percent since 1990, which is the second largest GSG reduction after Russia, according to a report issued by the EU statistics agency Eurostat on Tuesday. "The EU has the second largest GHG emission reduction achieved so far after the Russian Federation (– 29 % in 2014 compared to 1990)," the report titled "Sustainable development: a glance at where the European Union stands" said. According to the report, the European Union managed to reduce the GHG emissions mostly by reducing the supply and the use of energy. Other industrialized countries such as Australia, New Zealand, Canada, Japan and the United States have increased their greenhouse gas emissions over the same period, the report said. The report also provides an overview of the current situation on sustainable development in the bloc, comprising the issues of safeguarding the natural environment, social matters and economic progress. Greenhouse gases are capable of a trapping and holding heat in the atmosphere, while the increase of them provokes a greenhouse effect, which accelerates global warming.
