Helping you track your carbon emissions
Karai is your new eco-driving companion calculating your carbon footprint every time you drive. Karai gives you an eco-score to help you to drive more sensitively, and gives you the ability to offset your carbon footprint. Keep Karai with you on every journey to create a cleaner and more sustainable environment.

Driving your awareness
Karai learns your driving style and gives you scores for braking, acceleration and cornering smoothness. The way you accelerate, brake and navigate bends has a significant impact on your car’s fuel efficiency. Driving more eco-sensitively can help you to save on petrol and diesel long-term and will also reduce your vehicle’s impact on the environment.

Offset your emissions to help fund innovative projects
Rewilding more of our planet, planting more trees, protecting our existing wilderness areas and switching to more renewable energy sources, we can reduce our emissions and effectively offset the CO2 from your vehicle. These are exactly the innovative and essential projects that are supported by Karai to help build a better future for our world.

Choose what you want to pay
Karai is free to download and use, and you can pay to offset your emissions when you want to. You can even over offset your carbon footprint to stay carbon positive.

When you pay to offset your carbon footprint through Karai, your money is invested in projects including renewable energy schemes and afforestation programmes. These projects are verified and accredited by world leading carbon registries such as The Gold Standard (WWF), Verified Carbon Standard (VCS), and The United Nations.
Among the projects we support are UK based charities such as Plant a Tree Foundation and Ribble Rivers Trust, as well as international projects such as Eden Reforestation, Madre de Dios REDD+, and Brazilian Amazon REDD.

All suggestions and feedback are most welcome! Please visit our Karai website to get in touch: https://www.kar.ai/ or use the Settings menu in the app.
