Two reports from the European Commission analyze the sustainable use of biomass and biogas beyond 2020

The European Commission has published two reports that analyze the sustainable use of biomass and biogas beyond 2020:

Sustainable and optimal use of biomass for energy in the EU beyond 2020 (2017). This study provides an analysis of biomass supply potentials for energy use in the EU, projections of EU bioenergy demand post-2020, and an impact assessment of possible EU policy options for bioenergy sustainability post-2020, with a focus on biomass for heat and power.

Optimal use of biogas from waste streams. An assessment of the potential of biogas from digestion in the EU beyond 2020. (2016). This study assesses the potential role, cost and benefits of biogas, as well as the key barriers and drivers of biogas deployment in the EU until and beyond 2020.
