He works amongst others on charting and projecting international trade in biomass and biofuels (with a special focus on wood pellets), and identifying limitations and opportunities for bioenergy trade. His expertise includes solid biomass logistic supply chains and GHG balances including forest carbon accounting. The topics mentioned above are also covered by past and ongoing projects, e.g. the EC-funded projects Biotrade2020+, BioSustain and the TKI-BBE funded project BioLogikN, which is also lead by Martin. Past EU- projects also include Pellets@las, EUBIONETIII, Re-shaping, DiaCore, and SolidStandards. Within the frame of these projects, Martin has organized several workshops (in the Netherlands and abroad) and given numerous presentations and lectures, amongst others in Brazil, Canada, the USA, Malaysia and more than 10 European countries. He also was contributing author to the bioenergy chapter of the IPCC Special Report on Renewable Energy Sources (SRRES). He is editor of two books, on internaiotnal bioenergy trade and mobilisation of woody biomass from boreal and temperate forests.
