My research focuses on modelling production and greenhouse gas emissions at the farm scale, including carbon sequestration offsetting. In addition, I have specialised in the estimation of ammonia emissions from manure management and soils, particularly in connection with emission inventories. I am co-chair of the Agriculture and Nature Expert Panel of the UN Task Force on Emissions, Inventories and Projections.
Here is a link to my presentation on the topic of how to calculate the extent to which carbon sequestration offsets the global warming effect of methane and nitrous oxide emissions, when using a carbon dioxide equivalent approach:
