Gumtree’s Carbon Calculator

Buying second-hand rather than new is an easy way to be more sustainable. However, measuring the environmental impact of choosing preloved can be difficult. So, to help you better understand your carbon footprint, Gumtree has partnered with the University of Leeds and developed a carbon calculator for thousands of items you will commonly find on our platform.

Gumtree research found that 1 in 2 people want to be more sustainable this year. Looking second-hand first for what you need rather than defaulting to buying new is an easy way to reduce your carbon footprint.

Our platform has hundreds of thousands of items for sale in your local area – from washing machines to clothes, garden furniture to sports equipment. And to boost that Good Find feeling when you have what you want, our carbon calculator will tell you how much CO2e would be created to produce the item new.

How does Gumtree’s carbon calculator work?

Our carbon emission saving calculator gives an estimated equivalent figure of the carbon footprint that would be generated if you bought an item new versus buying it preloved.

The data for the calculator is taken from the official UK Government analysis of the carbon footprint of UK residents, available to view here.

The statistics are provided using a model, developed at the University of Leeds, that calculates the embodied Greenhouse Gas Emissions (GHG) associated with the production of all goods and services consumed in the UK. The model provides a conversion factor that provides an understanding of embodied GHG emissions of spending £1 of a given product.

The factors are for products supplied for consumption in the UK, but do not take account of the emissions relating to the production of products imported for intermediate consumption, ie. those products that are used by UK industries in the process of supplying products for consumption in the UK). The estimates do not incorporate any allowance for emissions relating to the formation of capital assets, whether in the UK or overseas.

Individual product prices have been calculated according to research on approximate estimates of average spend on each item in the UK.

What is the carbon footprint of my item?

Our model uses the Government’s conversion factors to find the equivalent carbon footprint of common items. It is often easier to think about emissions in terms of daily activities such as having a hot shower, heating a house or taking a flight. The images on this page highlight the environmental impact you could have by swapping from buying new to preloved.

*Disclaimer – The data provides an average carbon footprint for the product and does take into account that there could be any variation within the sector dependent on the specific product or brand. It is a rough indication of the carbon footprint associated with a product.
