Emissions Calculator

EGO and Challenge 2025 have created a simple carbon footprint calculator to find out how much emissions your petrol garden tools produce. Simply enter information on the tools you use most often and we’ll do the rest before offering suggestions on how to reduce your carbon footprint.

Whether you’re a user of garden tools at home, as a trade professional or work for a local council maintaining parks and green spaces, you will use one or many petrol garden tools. Most users aren’t aware of the damage those tools are doing not only to themselves but those around them and the whole of planet Earth.

How to use the Challenge 2025 emissions calculator

Simply select the tools you use on a regular basis – the calculator allows for the selection of more than one tool. Next, fill out how many hours and minutes you use that specific tool a week. Be as precise as possible to generate an accurate result. After that, click “Get Results” to see your emissions impact spelled out in easy to understand terms.

Once you have your results, you will see how much carbon monoxide and carbon dioxide (CO2) your tools create weekly, monthly and yearly (based on 7 months of gardening). You will also see a breakdown of how far you could travel with how much carbon is produced from your gardening activity. 

Finally, you will see a calculation of how much particulate is produced which can be inhaled and pose a great risk to our health. Alongside this is how much fuel in litres you have used on a weekly, monthly and yearly basis. 

Next Steps

After understanding the carbon footprint your petrol tools are having on the planet, we will present you with options to switch to battery powered tools to help bring your emissions down. You will also learn how many trees need to be planted to offset your current environmental impact.

This tool along with our Education Pack can also be used in schools to help understand the impact of actions on our planet. You can find out more about our mission to switch from petrol power to battery powered tools by reading our manifesto and downloading our report – a detailed investigation into the significant negative impact of petrol power tools.
