Good stats on carbon saving

We know that ‘carbon footprint’ is a simple phrase for a complicated idea.

That’s why we use stats to compare your energy usage to scenarios that make a bit more sense. Below we’ve included more detailed explanations along with source information for some of our most popular stats.

Carbon savings

We supply you through the National Grid, which is like a dirty pond of electricity. When you switch to us, we match all the electricity you use over a year with electricity sourced purely from renewables. It’s like pouring fresh water into that pond. Slowly but surely we’ll clean things up.

What’s the impact on climate change? Well, the energy you use at home accounts for around half of your personal carbon footprint.

This is approximately 1.25 tonne of CO2 from electricity and 2.5 tonne of CO2 from gas, per year. The other half of your personal carbon footprint comes from transport, which accounts for around 2 tonnes of CO2 per year. This means that by switching to Good Energy’s 100% renewable electricity and carbon neutral gas you are reducing your carbon footprint from your energy at home to 0, effectively cutting it in half. 

What's more - if you drive an electric vehicle and switch to Good Energy from a competitor's brown tariff you can could reduce your carbon footprint by 75%.

To calculate the contribution domestic electricity and gas consumption makes to your annual carbon footprint, we first looked at the national breakdown of per capita emissions. We then tallied the total of Domestic and Transport emissions and calculated the reduction that would occur if ‘Domestic Electricity’ and ‘Domestic Gas’ resulted in zero carbon emissions.


Regional carbon savings in Bristol

If 1 in 10 Bristol residents switched to Good Energy, their whole carbon footprint would reduce by 27,000 tonnes of CO2 every year. That’s the annual emissions of 17,000 cars! To calculate CO2 reduced, we first looked at the average household electricity consumption of each area in Bristol.



We then combined this with the number of households in these areas and added them all up to calculate the total domestic electricity consumption of Bristol. We multiplied this by the average carbon content of UK electricity to arrive at a total carbon footprint.

How can you calculate the carbon footprint of a car?

To calculate the carbon footprint of a car, we multiplied the average annual mileage by the CO2 emissions of a new car. We then divided our Bristol carbon figure by this, to calculate how many cars we could hypothetically take off the road in Bristol. 

The average Good Energy electricity customer reduced their emissions by 1.34 tonnes of carbon last year by being 100% renewable. That’s the equivalent of not driving 6,500 miles!

The average emissions are based on calculating the UK’s grid average electricity emissions of 420g CO2 per kWh and Good Energy’s zero carbon electricity. The typical domestic consumption value was sourced from Ofgem.

When 1.34 tonnes of carbon is compared to The Society of Motor Manufacturers and Traders (SMMT) average emissions of a new car (0.206 kilograms of CO2 per mile), switching to Good Energy for a year is equivalent to avoiding 6,500 miles of road travel in a car.

This doesn't relate to electric vehicles, as they can be charged off 100% renewable electricity so that driving can be effectively zero carbon.  

The carbon footprint of a piece of paper

Did you know that producing 100,000 sheets of paper from new sources requires over 8 trees and almost 2,000kWh of energy?

It has a carbon footprint of 6,000kg (from energy required to create the paper and dispose of it in landfill eight times). Paper can, on average, be recycled seven times. It’s much more energy efficient to create new paper from recycled sources than to create it from scratch. A ‘life-cycle carbon footprint’ looks at the total amount of energy required to produce, recycle and dispose of paper throughout its useable life.

The same amount of paper recycled seven times, has a life-cycle carbon footprint of 3,200kg (from the amount of energy required to create the paper, recycle it seven times and then dispose of it in landfill). 

That’s a 47% saving by using recycled paper. 

Read about the emissions factors. An A4 sheet measures 0.21m by 0.297m. Therefore, a sheet of 80gsm A4 weighs 5 grams and 100,000 sheets weigh 499kg.

Your energy usage

If you turn down your room thermostat by one degree, you could save up to £90 and 360kg CO2 a year. Energy Saving Trust
