National Emission Projections

Greenhouse gas emission projections provide a forecast of future emissions and are a valuable analytical tool to inform how Ireland will comply with 2020 targets under the EU Effort Sharing Decision (Decision 406/2009/EC). The EPA develops national emission projections on an annual basis, in collaboration with relevant State and other bodies. This collaboration ensures consistency with economic forecasts and with projected activity in sectors including energy, agriculture, and industry.


The National Climate Change Strategy (2007) designated the EPA with responsibility for developing national emission projections for greenhouse gases for all key sectors of the economy. Emission projections serve to inform national policy initiatives and allow Ireland to comply with EU reporting obligations on projections (Monitoring Mechanism Regulation 525/2013). 

Two scenarios are produced showing a different outlook for emission levels depending on the level of policy implementation:

  • With Existing Measures (WEM) scenario assumes that no additional policies and measures, beyond those already in place by the end of 2015, are implemented.
  • The With Additional Measures scenario assumes implementation of the With Measures scenario in addition to, based on current progress, further implementation of Government renewable and energy efficiency targets for 2020, as set out in the National Renewable Energy Action Plan (NREAP) and the National Energy Efficiency Action Plan (NEEAP).  For 2017 projections, the With Additional Measures scenario takes into account an expected shortfall in achieving full energy efficiency targets and renewable energy targets for electricity, transport and heat as set out in the NEEAP and NREAP.

Under the EU Commission’s Climate and Energy Package, Ireland is required to deliver a 20% reduction in non-ETS greenhouse gas emissions by 2020 (relative to 2005 levels). In addition, Ireland also has binding annual emission limits for the period 2013-2020 to ensure a gradual move towards the 2020 target. The non-ETS sectors cover those that are outside the EU Emissions Trading Scheme and includes the agriculture, transport, residential, commercial, waste and non-energy intensive industry.

As part of the 2017 projections reporting the EPA has produced a summary report which provides an updated assessment of Ireland's progress towards achieving its emission reduction targets set under the EU Effort Sharing Decision for the years 2013-2020.  The report also provides information on the EU and national policy position context and emission projections beyond 2020.
