GHG emission reduction in the non-ETS (emission trading system) sector is a relevant component of environmental policies for the next programming period. Specific policy matters of the next programming period are unclear, yet in general, it is clear that the reduction of emissions or at least the introduction of emission abatement measures are binding on agriculture. 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. Such a research study has been done and the measures have been analysed in Latvia. A MACC, however, gives a relative notion of the effects of GHG emission abatement measures on sustainable development in Latvia. The research aim is to analyse the effects of GHG emission abatement measures on sustainable development in Latvia. The key instrument of the present research is Integrated Impact Assessment; according to it, experts from various fields identify the effects of GHG emission abatement measures on the economy, the environment and social development, determining its vector (positive/negative) as well as effect intensity (on a scale from 1 to 3). The results showed that some measures, e.g. promotion of biogas production, could have a negative effect in some sustainability sub-dimensions, yet overall the GHG emission abatement measures make positive and significant effects not only on the environment but also on sustainability at large. At the same time, it has to be taken into consideration that the effects identified by the experts are indicative and more research has to be done to make a more accurate assessment.
