Based on a comprehensive study of 403 tree species and more than 600.000 individual trees from all over the world the scientists question the time-honoured paradigm that old trees grow less than the younger trees.

With a new report on “LCA screening of biofuels & iLUC, biomass manipulation and soil carbon” 2.-0 LCA consultants have contributed to the ongoing discussions in Denmark on the effects of biomass and other energy sources on climate change. Our report (in English) is an appendix to a Danish report published by the green think tank CONCITO on the climate effects from bio-fuels: ‘Klimapåvirkningen fra biomasse og andre energikilder, Hovedrapport’. The main report concludes that virtually no energy is completely…
