Methane Emissions

Methane (CH4) is a greenhouse gas that contributes to climate change by trapping heat in the Earth's atmosphere. It is estimated to be 28-36 times more potent at trapping heat than carbon dioxide (CO2) over a 100-year time frame. Methane is produced through both natural processes, such as wetlands and wild animal digestion, and human activities, such as the extraction and transport of coal, oil, and natural gas, and from the raising of livestock. Reducing methane emissions is considered a key strategy in the global ambition for limiting climate change to 1.5℃ by 2050.

Existing natural gas supply chains have long been a source of methane. Our work examines the scale and sources of methane throughout the natural gas supply chain. 

In response to demands for resource efficiency and the need to move away from fossil fuels, the biogas supply chain has expanded in recent years. Whilst bioenergy is perceived as a clean energy solution, there remains potential for GHG emissions.  The main commodity produced – biomethane – has the same GHG properties as methane from natural gas. As the supply chain expands, we need to be just as vigilant in understanding and tackling emissions.
