Why move to green business energy?

Renewable business electricity – wind turbines

Renewable business electricity

  • 100% of the electricity supplied is renewable, each MWh is backed by Guarantee of Origin (GoO) certificates [1]
  • Guarantee of Origin certificates are traded documentation for the buying of electricity from renewable sources. The certificates are electronic and evidence the origin of the electricity generated
  • Our renewable electricity product is independently certified by the Carbon Trust, giving you confidence in our renewable supply
Renewable and Carbon offset business gas – biomethane gas

Renewable and Carbon offset business gas

  • 10% biomethane gas, each KWh of biomethane gas is backed by Renewable Gas Guarantee of Origin (RGGO) certificates [2]
  • Biomethane is a renewable gas, produced from biodegradable matter such as food waste, sewage or energy crops. As well as being used to produce heat, biomethane is increasingly being used as a road fuel
  • 90% offset with independently verified carbon reduction projects. We buy our carbon offsets from a Gold Standard Foundation landfill gas extraction and electricity generation site in Turkey


Landfill Gas Extraction and Electricity Generation

Cutting carbon emissions around the world

We buy independently verified carbon credits from a landfill gas extraction site in Turkey, verified by the Gold Standard foundation. The project involves the building, operating and maintaining of the two landfill waste-to-energy systems consisting of landfill gas collection systems, flaring stations and gas engines, coupled with generators to produce electricity.

The gas engines combust the landfill gas to produce electricity, and any excess gas is flared to avoid release into the atmosphere. The generated electricity is sold to the National Grid. Landfill gas consists mainly of methane, therefore the extraction of this gas by the project saves the environment from large amounts of gas emissions that would have otherwise been emitted from the landfills and contributed to global warming. Generation of the electricity from the landfill gas replaces electricity otherwise generated by fossil fuel-based power plants.

What is renewable energy?

Solar, tidal, wind, geothermal and biomass are all examples of renewable energy because they all come from natural sources which replenish and don’t run out – unlike fossil fuels which are running out and contribute to global warming.  Renewable energy is also known as green energy, sustainable energy, alternative energy and clean energy.

Renewable energy comes from these natural resources:

Depiction of the sun which is a source of renewable energy


Depiction of tidal waves which are a source of renewable energy


Depiction of a wind farm turning blade which is a source of renewable energy


Depiction of biomass fuel which is a source of renewable energy


They’re called sustainable because these resources shouldn’t run out. They’re also often referred to as alternative energy because they can replace the use of traditional, reliable energy sources like coal and oil which will eventually run out.

Our fuel mix

Renewable energy is the fastest-growing energy source. It's is set to grow by 1,200 gigawatts (GW) in the next 5 years. This is line with government targets where energy suppliers need to have less reliance on fossil fuels. In fact, by 2025 the government wants all coal-fired power generation to end [3].

For all our non-green plans, British Gas currently uses 76% renewable energy sources and this is much higher than the industry average at 38%.

You can see the breakdown of the fuel we use in our fuel mix.

FAQs on green business energy

What makes this tariff green?

A: Some tariffs offer additional benefits to the environment on top of any legal obligations the energy supplier may have, this is called 'additionality’. Our Green Future tariffs provide additionality. That’s because the 100% renewable electricity and 10% green gas that is matched to your use is over and above our existing environmental commitments. We also offset the carbon footprint created from 90% of the gas that you use on this tariff by supporting emission reduction projects.

What is renewable electricity?

A: Renewable electricity, also known as green or clean electricity, is made from renewable sources, such as the sun, wind, or biomass. Unlike electricity produced from fossil fuels, renewable electricity is a cleaner, more sustainable alternative, and helps reduce your carbon footprint.

Why should my business use green energy?

A: Renewable electricity technologies have a much lower environmental impact than electricity generated with fossil fuels and can play a role in slowing global warming by cutting the amount of carbon dioxide released into the atmosphere. Because renewable electricity is produced from sustainable sources, it won’t run out any time soon. And eventually it could replace fossil fuels altogether.

How is renewable electricity generated?

A: Renewable electricity can be created from sources such as the sun, wind, tidal and biomass, with different technologies and processes used for each one.

How does renewable electricity get to my business?

A: We match 100% of the electricity you use on renewable contract with electricity from renewable sources. This means that for 100% of the electricity you use, the same amount of electricity from renewable sources will be fed into the national grid.

It isn't possible to trace the electricity from a particular source right through to your business because it all gets mixed up in the grid. But we can show that 100% of the electricity you use has been matched with renewable sources and fed into the grid. We do this by buying Guarantees of Origin certificates (GoOs) each time we buy electricity from renewable generators through agreements called Power Purchase Agreements (PPAs). Ofgem issues one GoO certificate per megawatt-hour of renewable electricity to eligible generators in the UK. 

What’s green gas?

A: Green gas (also known as biomethane) is made from renewable sources such as leftover food and farm waste. It’s just like normal gas made from fossil-fuels, but it’s produced differently and is virtually carbon neutral when burned, making it a greener, more sustainable option for the future.

How is green gas better for the environment?

A: When fossil fuels are burned, they release carbon dioxide that was created and stored millions of years ago into the atmosphere. But because green gas is made from organic waste, the carbon it releases is balanced by the carbon dioxide that the plants absorbed whilst they were growing. That's why we describe it as carbon neutral.

Organic matter naturally releases CO2 when it decomposes, and by capturing it and converting it into useful green gas, it can then be used to power your business. Unlike regular gas, it doesn’t come from fossil-fuels which are a finite resource that will eventually run out. Because organic matter grows using the sun's energy, it's a continually-renewable source of energy, making it a greener, more sustainable option for the future.

How can businesses use renewable energy

A: Businesses can use renewable energy by signing up to our renewable contract option where we match 100% of the electricity you use with electricity from renewable sources. If you're a gas customer, we match 10% of the gas you use with Renewable Gas Guarantee of Origin certificates and we offset 90% of your carbon footprint by supporting carbon emission reduction projects in the developing world. We do this by purchasing Certified Emissions Reduction certificates or CERs.

[1] Every unit of electricity and/or gas used will be supplied by British Gas matched to renewable certificates or renewable certificates and carbon off-setting projects to ensure that your business electricity and/or gas supply is backed by 100% renewable certificates or a mix of renewable certificates and carbon off-setting for the term of your contract. British Gas will hold the necessary number of Guarantee of Origin/ Renewable Gas Guarantee of Origin certificates as evidence of this supply and Emission Reduction certificates. In the event something changes and British Gas can no longer guarantee a renewable supply they will write and let you know.

[2] Business gas only we buy independently-verified carbon credits from qualified and registered projects. Our current Landfill Gas extraction project is verified by the Gold Standard Foundation. Depending on the popularity of the tariff or for other reasons beyond our reasonable control, we might purchase carbon credits from other emission-reduction projects not advertised at sale. We’ll always do our best to ensure that the carbon credits we buy are of a comparable quality and standard and we will use our best endeavours to purchase enough carbon credits to offset the carbon footprint created from 90% of the gas you use on this tariff. However, failure to do so will not constitute a breach of contract by us or give rise you having the right to terminate the supply contract.
