Biogas and Biomethane Supply Chains Contribute Much to Global Methane Emissions


A new Imperial analysis has found that biogas and biomethane, while more climate friendly, leak up to twice as much methane as previously thought.

Although biogas and biomethane remain climate-friendlier than non-renewable alternatives, the researchers call for better monitoring and fixing of leaks to ensure biogas and biomethane continue to live up to their green credentials.

Biomethane and biogas are produced from the breakdown of organic matter including food, animal waste, energy crops, grass, or sewage sludge, making them renewable alternatives to natural gas, coal and oil.

However, researchers at Imperial College London have identified potential pitfalls in energy supply chains for these climate-friendlier gases, concluding that more efforts should be made to reduce methane leakage.
