A new marginal abatement cost curve (MACC) for ammonia emissions has been published by Teagasc. The publication is titled "An Analysis of the Cost of the Abatement of Ammonia Emissions in Irish Agriculture to 2030," and outlines the steps that can be taken to reduce ammonia emissions from Irish agriculture and the costs of achieving this. The document was prepared by the Teagasc Gaseous Emission Working Group.
