We currently supply our customers with natural gas, a fossil energy source formed deep beneath the earth’s surface. Renewable gas (also known as biogas or green gas) is an environmentally friendly, renewable energy source produced when organic matter, such as food or animal waste, is broken down by microorganisms in the absence of oxygen. 

Unlike renewable electricity, there is currently very little renewable gas available here in the UK.  

We're exploring alternatives to natural gas, such as heat pumps or hydrogen, for household heating. But, for now, most homes have little alternative to natural gas. Nature can help curb the carbon-dioxide emissions from the full lifecycle of this gas, so one way we offset our carbon emissions is by supporting nature-based projects around the globe.
