Air and climate

English
Hide / Show Abstract

Emissions of pollutants and gases from human activities have many negative effects on the local, regional and global environment. Greenhouse gas (GHG) emissions exacerbate the natural greenhouse effect, leading to temperature changes and other consequences for the earth's climate. Air pollutants such as sulphur oxides (SOx), nitrogen oxides (NOx), carbon monoxide (CO), and volatile organic compounds (VOC) contribute to regional and local air pollution, and affect human health and ecosystems.

Hide / Show Abstract

Greenhouse gases refer to the sum of seven gases that have direct effects on climate change : carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3). The data are expressed in CO2 equivalents and refer to gross direct emissions from human activities. CO2 refers to gross direct emissions from fuel combustion only and data are provided by the International Energy Agency. Other air emissions include emissions of sulphur oxides (SOx) and nitrogen oxides (NOx) given as quantities of SO2 and NO2, emissions of carbon monoxide (CO), and emissions of volatile organic compounds (VOC), excluding methane. Air and greenhouse gas emissions are measured in thousand tonnes, tonnes per capita or kilogrammes per capita except for CO2, which is measured in million tonnes and tonnes per capita.
