The sky’s the limit!

The aviation industry needs a fuel that will cut pollution and fight climate change. Can you supply it? We need the jet fuel of the future now!


Canadians love to fly.

We’ve got a big country and we need to cover long distances.

For work

For family

And for fun

But to fight climate change, we need to find cleaner fuel for our airplanes.

That’s why we’ve launched the Sky’s the Limit Challenge

We’re challenging Canadians to develop an affordable, cleaner jet fuel for our planet.

The Cross-Canada Flight Competition is taking off!


3,000 km flight

$1 million will be awarded to the first producer with a made-in-Canada biojet fuel that meets the criteria for a major Canadian airline to purchase and use for a flight across Canada (10 percent minimum blend).

Submit your fuel now!

Check out the applicant guide for more details about the flight challenge and its terms and conditions.
