Let’s talk about your carbon footprint

Your carbon footprint is the impact we have on the environment.

Most of our activity and lifestyle choices – directly or indirectly - leaves an impact on the environment that can be measured as carbon dioxide (CO2) equivalent.

Understanding your carbon footprint

Doing your bit to combat climate change can be a daunting task but it doesn’t need to be complicated, and could save you money. The easiest way to start is by taking a look at your carbon footprint.

How is my carbon footprint calculated?

Your carbon footprint is calculated by working out the total greenhouse gases released as we go about our everyday lives.

It is often expressed as kilograms of carbon dioxide equivalent (CO2e) to help show the impact that we create on the environment. CO2e includes carbon dioxide and other greenhouse gases.

From the type of car you drive to the construction materials of your new wardrobe – it all leaves a footprint. 

How can I work out my carbon footprint?

The simplest way to work out your impact on the environment is by using a carbon footprint calculator. These could help you to understand how much carbon you are creating.

Once you have a starting point, you can then start thinking about what you could change to help reduce it.

From energy saving light bulbs, walking instead of driving or installing solar panels - there are options for every budget.

How can I reduce my carbon footprint?

Getting started is the hardest part. But once you begin making sustainable choices, you’ll find new ways to live a more sustainable life. And you could save money too.
