A research study entitled "Technical assessment study for biogas optimal use post 2020", commissioned by the European Union, identifies the main strengths and weaknesses of the biogas and biomethane markets in the Union's 28 member states. Factors favouring the market’s development are a stable political environment and sustainability targets set at the European level. The lack of the same factors, on the other hand, together with an absence of incentives, are among the main barriers.
