Welcome to the CAfS guide to sustainable living and reducing your carbon footprint.

In this section, you’ll find lots of information and resources to help you green up your lifestyle. Much of the guide is also relevant to businesses, but for more specific information please visit our business section.

Living sustainably means meeting our needs without compromising the ability of future generations to meet their needs.

To do that we need to protect our environment. But we also need to ensure that we all have food, water, shelter, healthcare, education and a decent income. Otherwise we’ll go back to plundering the Earth’s resources to survive.

You can find out more by looking at the United Nations Sustainable Development Goals or this video on Doughnut Economics by Kate Raworth.

As the UN’s 17 goals show, living more sustainably isn’t just about your carbon footprint. Within this bigger picture, CAfS focuses on action to combat climate change, and the guides in this section look mainly at reducing your greenhouse gas emissions, which are the main cause of climate change.

Where do greenhouse gases come from?

Carbon dioxide is the most prevalent greenhouse gas. It is emitted from natural processes, such as breathing, but the huge increase of this gas in our atmosphere since the industrial revolution has mainly come from burning fossil fuels to power our homes, our transport and our industries.

However, it is not the only greenhouse gas. Methane, for example, has twenty times as much global warming potential, and comes from livestock and landfill, as well as from fossil fuels.

Make the change!

Some aspects of your life will have a bigger impact than others on your carbon footprint. If you’re like most people, food and drink, household energy and transport will be causing the biggest chunks of your carbon emissions.

Food and drink account for a quarter.

Household energy is around 16%.

A car adds about 14%.

Other ways you’ll add to your carbon footprint include shopping and waste, for example.

If you want to lower your carbon footprint and tread a little more lightly on the world, explore our guides below. They offer practical advice to help you make changes.

Lines v circles

At the heart of these guides is the idea of a ‘circular economy’, recognising that many of our resources are finite and we should be reusing them, instead of the ‘linear economy’, where they’re thrown away. Find out more about this in the circular economy box on this page.
