There are an increasing number of initiatives for sustainable biomass and sustainable biomass for bio-energy in particular. Most parties agree that a harmonized system in the EU, and eventually the world, is superior to many different (country) initiatives. Ecofys carried out a piece of work for WWF International which considered the developments in terms of biofuels sustainability in the UK, the Netherlands and Germany to open the discussion with the EC and interested member states on the development of a harmonised reporting scheme.
