National Emissions Inventories

The United Nations Framework Convention on Climate Change (UNFCCC) and its Kyoto Protocol provide the basis for international action to address climate change. Parties to the convention and its Kyoto Protocol are committed to developing and publishing the national emission inventories of greenhouse gases (GHGs) which is a key element of assessing progress towards meeting commitments and targets.  View further information on the international climate change processes.


The EPA compiles Ireland's national greenhouse gas emission inventory on an annual basis. This inventory is submitted to the European Commission and UNFCCC each year by 15 January and 15 April respectively.

Emissions data for the following gases is reported on an annual basis: Carbon Dioxide (CO2,) Methane (CH4), Nitrous oxide (N2O), Hydrofluorocarbons (HFCs), Perflurocarbons (PFCs), Sulphur Hexafluoride (SF6), and Nitrogen Trifluoride (NF3).

Emissions are classified into the ten following sectors; Agriculture, Transport, Energy Industries, Residential, Manufacturing Combustion, Industrial Processes, F Gases, Waste, Commercial Services and Public Services.

The latest greenhouse gas inventory covers the time period 1990-2015. A graph of the latest time series is shown below.
