Remove carbon from the atmosphere with Colt’s Customer Reference Programme.

When you share your experience with Colt, you will receive a sustainability reward in the form of carbon removal.

“We are constantly in contact with our partners to make the purchase of our products and solutions as sustainable as possible, both in production but also in IT. With Colt, we work with a company that pursues ambitious ESG goals on its own initiative and implements corresponding measures. This helps us in our sustainability efforts”

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 we'll present you with a quantity of biochar for carbon footprint reduction, accompanied by official certification.



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 1 million views a year.

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: we'll invest in biochar - a permanent carbon removal solution - and provide you with a certificate representing the quantity of carbon removed permanently from the atmosphere on your behalf.

Permanent carbon removals 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 permanent carbon removal certificate, 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.

Did you know?

1 tonne of CO2e emissions is an equivalent of:

  • 51 beef steak meals (each meal with 150g of beef steak) (equivalent of the production of 7.75 kg of beef steak)
  • One-way trip from Paris to New York (for 1 passenger in an economy class, distance: ca. 5,800 km)
  • CO2 emissions that an average person in the European Union emits during less than 2 months.

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.
