Teagasc Climate Action Strategy - The Road Map for Agriculture

Teagasc Climate Action Strategy - The Road Map for Agriculture

Ireland has set out its commitment to reduce overall greenhouse gas (GHG) emissions by 51% by 2030 and achieve climate neutrality by 2050.

This meets Ireland’s commitment to the Paris Agreement to keep temperature rise to 1.5°C and is in line with EU policy, and it is supported in law by the 2021 Climate Action and Low Carbon Development (Amendment) Act.

The target for “Agriculture” is a 25% reduction (5.75 Mt CO2eq).

Delivering the reduction in Greenhouse Gas emissions required to meet the new targets for Agriculture will require a significant transformation in Ireland’s agriculture and food production system. Ensuring that Irish farmers and food producers are environmentally, socially and economically sustainable throughout the period of transformation and beyond will be critical.

Supporting farmers in this transformation of the Irish agri-food production system will require significant additional research, advisory and education resources and a whole of industry effort across the Agricultural Knowledge Innovation System (AKIS).

The Road Map for Agriculture

Teagasc has set out opportunities to reduce GHG emissions in three phases. In Phase I, initial implementation of the technical measures in the current Marginal Abatement Cost Curve (MACC) for Agriculture, 2019 can bring the sector about one third of the way to the 2030 target, almost-ready technologies (Phase II) and early stage technologies (Phase III) are required for the remaining two thirds.

While the pathway shown below is linear, it is unlikely that this will be the case in reality as, for example, not all of the Phase I measures will be implemented on farm at an early stage, while some of the Phase II and Phase III measures may emerge more quickly or slowly than currently anticipated.

The updated Teagasc GHG MACC, to be published in 2023, will give a more accurate assessment of the scale and timeline of the mitigation options available to Irish agriculture. The National Climate Action Plan 2023 will provide clarity of policy actions that will support the decarbonisation of Irish agriculture, and it will be informed by the reports of the Food Vision Dairy and Food Vision Beef and Sheep Groups.

In addition, the science behind how methane contributes to global warming is constantly evolving. For example, changing the metric for assessing its contribution from the current GWP100 to GWP* would be very significant in the assessment of the impact of methane. GWP100, accounts for methane emissions evenly across a 100 year time-horizon, while GWP* reflects methane existence as a short- lived gas that causes warming for about a 12 year period. This means that using GWP* in a herd with stable methane emissions will show a much lower warming effect coming from livestock. While the concept of GWP* is discussed in the IPCC’s AR6, it is not yet used in the international accounting system for greenhouse gas emissions.
