Past emissions are taken from the The UK National Atmospheric Emissions Inventory (NAEI). Projections are based on Department of Agriculture, Environment and Rural Affairs (DAERA, Northern Ireland) analysis to support the draft Climate Action Plan 2023-2027. These were calculated by DAERA following assumptions of mitigation efficiency and rollout potential, covering 4 scenarios from most to least conservative: headwinds, central, tailwinds and tailwinds + additional adoption of emission suppressing feed additives. Gases are reported in quantities of methane, nitrous oxide and carbon dioxide, then aggregated under a range of 'carbon dioxide equivalent' reporting metric approaches (the 100-year Global Warming Potential, the 20-year Global Warming Potential, the 100-year Global Temperature change Potential and two applications of 'GWP*') based on standard practice and recent carbon reporting literature to illustrate different ways of weighting gases and inferring mitigation value. The weighting factors and calculations used to report emissions under these multiple metrics are supplied in an accompanying xlsx calculator tool.\n\nThe work was supported by the Natural Environment Research Council (NE/W004976/1).","distributionFormats":[{"name":"Comma-separated values (CSV)","type":"text/csv","version":"unknown"}],"distributorContacts":[{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"distributor","email":"info@eidc.ac.uk"}],"funding":[{"funderName":"Natural Environment Research Council","funderIdentifier":"https://ror.org/02b5d8509","awardTitle":"AGILE: Providing rapid evidence-based solutions to the needs of environmental policy-makers.","awardNumber":"NE/W004976/1","awardURI":"https://gtr.ukri.org/projects?ref=NE%2FW004976%2F1","orcid":false,"ror":true}],"hasOnlineServiceAgreement":true,"id":"425ba61b-0dbf-4e51-8158-f226ad1427cb","incomingCitationCount":0,"infoLinks":[{"url":"https://data-package.ceh.ac.uk/sd/425ba61b-0dbf-4e51-8158-f226ad1427cb.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"inspireThemes":[{"theme":"Agricultural and Aquaculture Facilities","uri":"http://inspire.ec.europa.eu/theme/af"}],"keywordsOther":[{"value":"greenhouse gas emissions","uri":"http://www.eionet.europa.eu/gemet/concept/15192"}],"keywordsPlace":[{"value":"Northern Ireland"}],"keywordsTheme":[{"value":"Agriculture","uri":"http://onto.nerc.ac.uk/CEHMD/topic/1"},{"value":"Climate and climate change","uri":"http://onto.nerc.ac.uk/CEHMD/topic/4"}],"licences":[{"value":"This resource is available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/OGL/plain"}],"lineage":"Agricultural greenhouse gas emissions for Northern Ireland under four different scenarios and multiple CO2-equivalence metrics were calculated.
