What makes our gas greener?

Radiator Green Gas

10% of the gas that we supply is renewable biogas generated in Britain. The rest we offset by investing in projects that improve access to green energy around the world.

What is biogas and how is it generated?

Biogas – also known as biomethane – is produced when organic matter such as leftover food and agricultural waste is processed in an anaerobic digester (AD). AD tanks let the waste break down in an environment that’s free from oxygen, producing methane gas. This is then extracted from the AD and injected into the gas grid.

Once it’s in the grid, biogas can be used in the same way as natural gas: it’s burnt to heat our homes and cook our food.

We supply 10% biogas because this figure represents the maximum percentage of the UK’s gas demand that can be met from sustainably produced, UK generated biogas.

How do we offset our gas?

We work with B Corp accredited sustainability solutions provider, SkootEco, to balance out the emissions from the gas you use at home.

All of the offseting projects we help fund are Gold Standard certified and support biogas generation globally.

But we chose them because they have a positive social impact too. This is shown in the UN Sustainable Development Goals they are proven to support, from affordable and clean energy to decent work and economic growth, through to improved health, gender equality and zero hunger.

This project in the Indian state of Punjab replaces inefficient wood fired mud stoves with clean and sustainable biogas cookstoves. Households use their cow’s dung to feed a digester, which produces biogas for use in cooking.

In replacing the use of wood it reduces the need to cut down trees, as well as preventing harmful greenhouse gases created by wood burning stoves.

By providing innovative clean cooking technologies including biogas stoves to rural households in Kenya, this project reduces wood used for cooking and water heating. It also reduces CO2 emissions from burning non-renewable biomass as well as capturing methane emissions from cattle manure.


In addition to reducing greenhouse gases, the project reduces deforestation and improves people’s health thanks to improved indoor air quality.

“The home biogas system has changed our lives. Nowadays I cook without any smoke in my kitchen. The growth of my nappier grass has improved so much, it grows faster and the stems are so thick. Now, I never lack feeds for my cows.” Jennifer Njeri, Tinga’nga Kiambu

This project uses manure from farms in the Ganzhou City of Jiangxi province to generate renewable electricity – while treating wastewater and creating fertiliser as a biproduct. With the support of investors like us, 10 new closed anaerobic directors are being installed to prevent methane emissions from being released.


This project improves access to clean, affordable energy, boosts jobs and economic growth and promotes climate action.
