Your carbon footprint
At Heathrow, we believe we can all work together to protect the environment when we fly. With commercial aviation contributing at least 2% of global carbon emissions, it’s important that we all do our bit to build a low carbon future by travelling more thoughtfully and offsetting the journeys that we do make.
Heathrow is working with the carbon company, CHOOOSE™, to make offsetting your journey simple. With a mission to create a more positive and action-oriented conversation around climate change, CHOOOSE™ makes it easy to act by connecting you with some of the most impactful carbon reducing projects around the world.
Calculate and offset your flight's footprint
By using our Flight Footprint Calculator you can calculate and offset the carbon emissions of your journey. CHOOOSE™ will guarantee that your payment supports third-party verified projects that avoid or reduce carbon emissions and help to combat climate change. You'll then receive a certificate recognising that the carbon footprint of your journey has been offset.
How it works
We all leave an unavoidable carbon footprint simply by the way we live, work and travel. When offsetting the carbon emissions from your flight, you balance the impact of your journey by actively supporting carbon reduction projects around the world.
1. Calculate your emissions
Use the Flight Footprint Calculator to calculate and understand your flight's emissions.
2. Offset your emissions
Make a payment to support a carbon reducing or avoiding project, which is certified to strict standards, like the Gold Standard or the Verified Carbon Standard.
3. Become a climate conscious traveller
You'll receive a certificate recognising that the carbon footprint of your journey has been accounted for.
We're on a journey of sustainable growth. Working with our passengers and partners, we aim to lead the way in protecting the environment when we fly. So as well as helping our passengers to make their own contribution and offset their journeys, we’re investing in natural carbon removal projects in the UK ourselves.
