Review of the evidence about carbon impacts of biomass energy. It concludes that the experience with bioenergy production and the pressure it places on land, water, biodiversity, and other natural resources has raised questions about its merits. Bioenergy must be evaluated by addressing both the stocks and flows of the carbon cycle.
Report from the experts who advised the European Commission, outlining that the sustainability criteria in the new EU renewable energy directive are grossly inadequate and that EU Member States will need to implement measures at national level to ensure that bioenergy delivers GHG savings over fossil fuels.
Analysis of land-use changes to tackle emissions. It concludes that carbon removed from the atmosphere through BECCS could easily be offset by losses due to land-use change. If BECCS involves replacing high-carbon content ecosystems with crops, then forest-based mitigation could be more efficient for atmospheric CO2 removal than BECCS.
Analysis of the results of a project looking at the carbon impacts of biomass which reach the conclusion that bioenergy, and forest bioenergy in particular, can be a potential contributor to increased GHG emissions unless there is a very strong policy framework that ensures effective management.

Analysis of the climate impact of replacing wood for coal in power generation, which suggests that biofuels are not carbon neutral and would increase atmospheric CO2 and worsen irreversible impacts of climate change.
