Why take part?

With the Colt Customer Reference Programme you can accelerate your sustainability progress, showcase tech success and boost your reputation.

Colt will do all the hard work. We’ll put your story in writing and turn your business milestones into steps towards a greener future.

The process is simple. Provide us with a customer reference and get carbon removal credits that you can declare on your sustainability reporting, while tangibly reducing your carbon impact.



Boost your reputation

With Colt’s Customer Reference Programme, your stories won’t slip away unnoticed. We’ll share your story on our social media, which has over 240,000 followers, and on, a site that gets over 100,000 views monthly.

This is a great way to showcase your team’s accomplishments and raise your brand’s profile.

Increase your carbon removal

When you participate in our Reference Programme, you can make a positive impact on the planet.

Share your story and you’ll receive a unique reward: a set of biochar carbon removal credits accompanied by official certification that shows your commitment to sustainability.

Carbon removal credits are an easy way to identify and measure your contributions towards reducing CO2 levels and improving the planet's well-being.

Offset your carbon impact

By receiving biochar carbon removal credits, you are mitigating a portion of your carbon impact and propelling your journey towards sustainability goals.

Biochar is a charcoal-like substance made from organic materials like wood chips, crop residues or other plant matter. It is increasingly recognised as a versatile asset that fosters both environmental well-being and agricultural support.

What's biochar?

Planting trees or using renewable energy can help, but they might not be enough to fully achieve your sustainability targets. To truly get there, businesses need to use efficient, complementary carbon removal techniques.

Biochar provides you with an added avenue. It removes carbon from the atmosphere, while also enhancing soil health and fertility when added to agricultural lands.
