Our gas keeps getting greener
It’s completely carbon neutral too
6% of our Green Gas comes from
And to make our Green Gas totally carbon neutral, emissions from the gas our customers use is balanced through verified carbon-reduction schemes that support local communities in Malawi, Vietnam and Nepal.
What is biomethane?
Biomethane is produced when organic matter – everything from the leftovers of your dinner to agricultural waste – is processed in an anaerobic digester (AD).
These big AD tanks act like a massive stomach, ‘digesting’ the waste. What’s essential is that there’s no oxygen present when the digestion happens.
As it breaks down, the waste releases methane gas. The same gas produced when plants, dinosaurs and other organic material rotted away in the ground millions of years ago – resulting in the pockets of natural gas that are drilled for today.
Gas we use to cook and heat our homes across the country, coming from the waste we don’t want.
So what’s the difference between biomethane and natural gas?
Burning anything creates emissions. But Green Gas comes from burning organic matter that has already absorbed carbon dioxide from the atmosphere while it grew. Burning it only releases that same amount of carbon dioxide, so doesn’t break what we call ‘the carbon balance’.
However, when we extract and burn fossil gas, we’re reintroducing carbon that has been locked away for millions of years, from a time with a very different climate. When we burn fossil gas we break the carbon balance, introducing more emissions to our atmosphere. It’s these emissions that add to man-made climate change.
Preventing methane emissions
Capturing biomethane and injecting it into our gas network or using it to generate electricity can help avoid harmful emissions. Some processes that create biomethane as a by-product, such as sewerage treatment, could be left to escape into the atmosphere.
Methane is a far more harmful gas to emit into the atmosphere than CO2, so capturing it to heat and power our homes is better for the planet than letting it go untapped.
Green Gas carbon reduction schemes
Our experts carefully selected a shortlist of carbon reduction projects and the finalists were chosen by our customers and staff.
They’re not only reducing emissions on a massive scale – they’re also bringing economic, social and health benefits to communities across the world.
In its quest to turn Vietnam’s waste problem into a clean source of energy for rural farmers and their families, the Vietnam Biogas Program has installed over 110,000 biogas plants across the country.
This sustainable technology uses animal waste (like pig poo) to replace traditional firewood. The energy produced helps over half a million people safely heat and light their homes, saving around 240,000 tonnes of CO2 a year while bringing employment and other economic benefits to Vietnam.

Kulera Landscape Program
This project in Malawi was founded to reduce deforestation by supporting Malawi’s rural communities with sustainable tools and skills.
45,000 families in the local area are now using more efficient cook stoves, cutting the use of firewood by 50% – helping protect the forests that are their home. The project’s carbon reduction is around 210,000 tonnes a year.
Improved cooking stoves in Nepal
The aim of these improved cooking stoves in Nepal is to reduce CO2 emissions by 65,000 tonnes a year while improving the everyday lives of families across the country.
