In 2020 Ireland missed its EU climate emissions target and without additional measures
will not be on the right trajectory towards decarbonisation in the longer 2030 and 2050 challenges.
Agriculture remains the single most significant contributor to overall emissions in Ireland. In the
absence of effective mitigating strategies, agricultural emissions have continued to rise. The purpose
of the review is to explore current research conducted in Ireland regarding environmental modelling
within agriculture to identify research gap areas for further research. 10 models were selected and
reviewed regarding modelling carbon emissions from agriculture in Ireland, the GAINS (Air pollution
Interactions and Synergies) model used for air pollutants, the JRC-EU-TIMES, (Joint Research Council European Union-The Integrated MARKAL-EFOM System) and the Irish TIMES model used for
energy, the integrated modelling project Ireland (GAINS & TIMES), the environmental, economic
model ENV-Linkages and ENV-Growth along with the IE3 and AGRI-I models. The review found
that data on greenhouse gas emissions for 2019 reveals that emissions can be efficiently lowered if
the right initiatives are taken. More precise emission factors and adaptable inventories are urgently
needed to improve national CO2 reporting and minimise the agricultural sector’s emissions profile
in Ireland. The Climate Action Delivery Act is a centrally driven monitoring and reporting system
for climate action delivery that will help in determining optimal decarbonisation from agriculture in
Ireland. Multi-modelling approaches will give a better understanding of the technology pathways
that will be required to meet decarbonisation ambitions.
