Greenhouse gas emissions

Real-time Air Quality information is available for than 15,000 stations in 2000 major cities from 132 countries, thanks to the huge effort from the world EPAs (Environmental Protection Agencies). It provides historical daily air quality data (e.g. PM2.5, PM10, O3, NO2) for different cities world-wide, and real-time monitoring via API.

The Greenhouse Gas (GHG) Inventory Data contains data on greenhouse gas emissions covering the period from 1990 to the latest available year, to the extent the data have been provided. The GHG data contain information on anthropogenic emissions by sources and removals by sinks of the following GHGs (carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), unspecified mix of HFCs and PFCs, sulphur hexafluoride (SF6) and nitrogen triflouride (NF3)) that are not controlled by the Montreal Protocol.

The IMF's Climate Change Dashboard has multiple cross-border indicators that explore CO2 emissions related to production in one country and determine how much CO2 emissions are used to satisfy demand at home and abroad. It takes into account decisions made by multinational companies on where they locate their operations. These indicators include 1) CO2 emissions embodied in trade, 2) trade in environmental goods, 3) trade in low carbon technology products, and 4) several factors related to emissions resulting from direct investment.
