In my previous post, I discussed the challenges of reducing non-CO2 greenhouse gas (GHG) emissions from agriculture and identified some of the strategies that are available or under development to allow farmers to reduce these emissions. But by how much would these strategies reduce projected emissions? What is the potential magnitude of the emissions reduction we should expect from agriculture in the coming decade? As in the previous post, I deliberately exclude a discussion of the potential to offset these emissions through land management and land use change although, as we will see, some insights into the potential to reduce emissions in the LULUCF sector will be covered in this post.… Read the rest
Mitigating agricultural emissions
Greenhouse gas emissions from agriculture (almost entirely non-CO2 emissions as defined in IPCC Sector 3) fell slightly in the EU-27 in 2018 but are still above their lowest level in 2012. Net emissions from cropland and grassland reported in the LULUCF sector also appear to have stabilised after some years of decline (EEA GHG Data Viewer). Further, projections of agricultural emissions by Member States, as I reported in this post, indicate that no significant reduction in emissions from agriculture is projected in the period up to 2030 even with additional measures in place.
Agricultural non-CO2 emissions are driven mainly by livestock numbers (particularly ruminants such as cattle and sheep) and nitrogen (N) fertiliser use.… Read the rest
