Marginal Abatement Cost Curve 2023 - Executive Summary

The Teagasc Marginal Abatement Cost Curve (MACC) identifies the most cost-effective pathway to reduce greenhouse gas (GHG) emissions and enhance carbon sequestration in the Agricultural, Land-Use, Land-Use Change and Forestry sectors plus (Bio) energy. This is the third iteration of the Teagasc GHG MACC; previous iterations were published in 2012 and 2018.

In this version of the MACC the FAPRI Ireland was used to model three potential agricultural activity scenarios on
how animal numbers will evolve in 2030; Scenario 1 (S1) is the most likely base case, while Scenario 2 (S2) and Scenario 3 (S3) project lower and higher numbers respectively. Additionally, two assumed adoption rates for each mitigation measure were assumed; Pathway 1 (P1) had an adoption rate similar to the last MACC, while Pathway 2 (P2) assumed a higher adoption rate that represented the maximum technically feasible.

The new Teagasc Marginal Abatement Cost Curve (MACC) to assist farmers and the Agriculture industry to reduce Greenhouse gas emissions, was launched on Wednesday, 12 July by the Minister for Agriculture, Food and the Marine Charlie McConalogue TD, in Teagasc Ashtown, Dublin.
