Together, Masternaut customers save 230,000 tonnes of CO2 each year.

How do you compare to your peers?

How did you do compared to last year?

With Masternaut’s Fleet CO2 Certification programme, our customers are automatically recognised.

How it works

Our patented CAN bus clip technology allows us to measure mileage and CO2 emissions accurately from each vehicle.

Our Catalytix Data Science team then compares emissions vehicle by vehicle (anonymised of course).

We are rewarding fleets with exceptional performance in:

  • Improvement year-over-year or
  • Better emissions than the benchmark across all Masternaut fleets (by fleet make-up)

How to participate

Our algorithms have identified the most efficient fleets among our customers based on their fleet make-up and performance. This certification is currently offered to Masternaut customers free of charge.

All certified customers will be informed via email in August 2018 and also will receive a mailing with vehicle stickers and a paper certificate in early September 2018.

We will be certify customers for their 2018 performance in Q1 2019.

I’m certified! What next?

You should have received an email and letter with instructions. If you have any questions or would like to order additional vehicle stickers or digital certificates, please contact us.

We can also send you a press pack to help you inform your customers. We’d be happy to put your logo on this page or discuss other joint marketing efforts.
