Biogases play an important and growing role in energy systems. Produced locally using organic waste, biogas and biomethane can contribute to energy security, waste management, emissions reductions and agricultural development.

This report presents a global geographical analysis of the untapped potential of biogas and biomethane from agriculture, municipal waste and forestry residues. Using detailed geospatial and production cost data, it assesses the potential, costs and suitability of over 30 types of sustainable feedstocks in more than 5 million locations worldwide.

The report also analyses:

• the current state of play of the biogas and biomethane sector, reviewing today’s policies, business models, consumption patterns and supply trends
• the environmental impacts of biogas projects, highlighting the importance of minimising associated methane emissions and responsibly managing organic waste streams
• the latest technologies and innovations in the sector, plus the scope for reducing costs through higher yields or economies of scale. 

The report is accompanied by an interactive map showing the sustainable technical potential of biogas and biomethane supply globally.

Key findings

• A relatively small share of the untapped potential for biogases is cost-competitive, but more can be unlocked if co-benefits are valued.
• The barriers facing biogases are significant, but not insurmountable.
• The environmental upside for biogases depends on how they are produced.
• Emerging market and developing economies lead in the potential for growth.
• Consistent and robust policy support is essential.
