Statement of the Problem: Environmental preservation is one of the EU multifaceted policy priorities that influences
all the other policies, among them agricultural (European Commission, 2011). Agriculture plays an essential role
in environmental preservation and in shaping climate policies. The agriculture of Latvia is the second largest source
of greenhouse gas (GHG) emissions, accounting for 24.2% of the total emissions produced in the country (Latvia’s
National Inventory Report, 2017). All the sectors of the economy have to contribute to the reduction of GHG
emissions.
Methodology & Theoretical Orientation: A popular way how to analyse GHG emission abatement measures is
to use a marginal abatement cost curve (MACC) that ranges the measures according to their costs and emission
reduction potential. The present research focuses on the MACCs designed for Latvia in relation to agricultural
emission reduction measures, which were complemented by two new measures, i.e. “paludi culture crops (reed
(for construction)) on arable land with organic soils” and “establishment of permanent crops (highbush blueberry)
in organic arable land”, that are associated with land use and land use change. Besides, the research analysed 23
measures, revealing their effects on both the agricultural and the LULUCF sectors.
Findings: The overall conclusion was that the interaction of most of the measures was neutral (12 measures). Only
three measures made positive effects on both sectors, meaning GHG emission reductions in both sectors. The effects
of two measures were unclear, as there was a lack of relevant research investigations. However, a negative interaction
was found for six measures, which was mainly due to the fact that an increase in green biomass produced by the
agricultural sector would result in additional emissions, while the LULUCF sector would increase CO2 sequestration
because of the increase in green biomass.
Conclusion & Significance: The research found that some of the measures incorporated in the complemented
MACCs had potential for CO2 sequestration and C accumulation along with the potential for GHG emission
reduction
