Ambitious science-based targets

Becoming the sustainable supplier of choice
As a large company with Global operations, we want to lead by example when working with our suppliers, partners, customers and communities to reduce our impact on the environment.

We have comprehensive, Near-Term and Long-Term Net Zero emissions targets approved by the Science-Based Targets initiative (SBTi). Our Long-Term Net Zero target has been approved in accordance with the SBTi Net Zero Standard.
Why set science-based targets?
We are already in the decade which will define the global response to the ever-increasing threat of climate change. It is important to Colt that we set robust, long-term targets firmly rooted in science to enable us to help mitigate the risk this has to humanity and the planet. The Science-Based Targets Initiative is recognised globally as the best authority in this space.

The long-term nature of science-based targets ensures that we have a clear direction for our business as well as shifting our focus towards the development of innovative solutions and new opportunities to support the transition to a low carbon economy. We also want to build in resilience to our operations by moving beyond current regulation.

This is the future of business, and our customers can rest assured that we will continually work hard to drive down emissions across our entire value chain. We must all act together for the greater good of our planet.
What is the Paris Climate Change Agreement?
Adopted in 2015, the Paris Agreement is the first-ever legally-binding climate change agreement.

It sets out a global framework to avoid dangerous climate change:

- Agree to limit global warming to well below 2 degrees

- Aim to limit the increase to 1.5 degrees since this would significantly reduce the risks and impacts of climate change

Net Zero

Our journey to net zero

Our de-carbonisation strategy focuses on improving energy efficiency, investing in renewable energy, and transforming supply chain practices as we continue to reduce our environmental impact and decrease our GHG emissions. In 2024, we continued to enhance our de-carbonisation strategy by incorporating Lumen EMEA activities and maintaining our ambition in the fight against climate change. This included developing a robust plan to achieve our near- and long-term targets and map out the associated financial impacts.

Following the GHG Protocol best practices and Colt Group’s rebaseline policy, we performed a comprehensive rebaselining exercise to accurately account for our expanded operational footprint due to the acquisition of Lumen EMEA. In 2025, we have engaged with the SBTi to communicate the increase in our emissions following the acquisition and to ensure that our SBTs hereafter will be reflective of our current operation and structural changes.

Our net zero initiatives

100% renewable electricity by 2030 (scope 2)

We're aiming to achieve 100% renewable electricity procurement for all Scope 2 electricity by acquiring Renewable Energy Certificates (RECs) for all sites globally by 2030.

Reducing indirect emissions

We're finding alternatives to travel + encouraging more sustainable options. We have set an internal cost of carbon (€13 per tonne of CO2e) to generate funding for investment in carbon removal initiatives.

Decomissioning old networks

In 2024, we shut down 32 switches and retired over 6,500 SDH devices across Europe, saving 13.2 GWh of grid electricity annually.

Electrifying our fleet

We're committing to a 75% pure electric fleet by 2030, with 38% already achieved by the end of 2024.

Working with our community

Through the Colt Sustainability Schedule we request our suppliers to develop and implement a plan to reduce carbon emissions.

Sustainable fuels + systems

We're transitioning to more sustainable fuels for use in on-site backup generators for data centres. We're reducing emissions from refrigerant leakages by improving detection systems and transitioning to low GWP refridgerants.

Innovating for a sustainable future

Our role as a digital infrastructure provider gives us a platform to accelerate sustainability transformations through innovation and the application of technological solutions, becoming the sustainable supplier of choice and helping customers improve their ESG performance.

We aim to advance our full value chain towards a more sustainable future by driving pioneering solutions and by creating a more agile, energy-efficient and modular digital infrastructure platform. Our innovation efforts steer cutting edge advancements, such as the ability to deliver on-demand solutions, reduce customer hardware requirements, and develop new smart building services, while continuing to lead in high-performance networking technology.

As our ESG strategy evolves, our product and operations teams collaborate with our ESG and marketing teams in a cross-functional forum to ensure the integration of sustainability across all aspects of our business.

Progress so far

Our progress against our 2019 baseline

In 2024, Colt’s Group total market-based carbon footprint was 352,635 tonnes of CO2e, a reduction of 35% in emissions compared to our baseline year 2019.

This is a reduction of 10% compared to the year prior. The emissions figures include the Lumen EMEA business which has been integrated into Colt Group’s carbon footprint through a rebaselining exercise.

As part of our carbon roadmap, we continue to focus on the decarbonisation of our value chain. In 2024, we have increased the percentage of renewable power that we procure by and have worked on increasing the accuracy of emissions related to our supply chain by incorporating more emissions-based data to replace some spend-based data.
