Earth Day 2025 offers an opportunity to reflect on the environmental responsibility shared by the technology sector. As digital infrastructure continues to expand, so does the importance of building and operating in efficient, resilient and environmentally conscious ways.
At Cologix, sustainability is a core focus across our operations. Through our Environmental, Social and Governance (ESG) strategy, we are committed to reducing emissions, improving efficiency and supporting long-term environmental goals — for both ourselves and our customers — across our data center footprint.
Reducing Greenhouse Gas Emissions at Scale
Cologix has committed to achieving carbon neutrality for Scope 1 and Scope 2 emissions. We are reducing greenhouse gas emissions across our footprint through targeted facility upgrades, smarter power management and sustainable design.
This includes installing high-efficiency UPS systems, replacing outdated cooling equipment and implementing energy monitoring tools to identify inefficiencies and optimize usage. These improvements are driving real results in greenhouse gas reduction in tech, helping both Cologix and our customers lower their carbon footprints.
Driving Energy Efficiency Across North American Facilities
Efficiency is essential to scalability. Cologix continues to optimize Power Usage Effectiveness (PUE) across North America through advanced cooling strategies and intelligent infrastructure.
We use free-air and natural environmental cooling wherever conditions allow, along with real-time airflow controls that reduce overcooling. In high-density environments, we implement liquid-to-chip cooling systems, which can improve cooling efficiency by over 25% compared to traditional air-based methods, depending on design and workload. These solutions enable energy-efficient colocation that balances performance with sustainability.
Powering Progress with Renewable Energy
Our sustainability efforts extend beyond design and operations to include the energy sources that power our facilities. Cologix continues to expand its use of renewable energy to help decarbonize data center operations and support customer ESG goals.
In Montréal, our data centers use hydroelectric energy, helping us offer cleaner, more sustainable infrastructure. We also actively pursue renewable sourcing in other markets, using flexible procurement strategies to grow responsibly and sustainably. As more customers prioritize clean energy, we’re building an ecosystem that supports them every step of the way.
Conserving Natural Resources Through Smart Operations
Cologix applies a holistic approach to sustainability, including careful management of water, materials and waste across our facilities.
In environments where liquid cooling is deployed, we use closed-loop systems that circulate coolant internally without relying on evaporative methods. This helps us significantly limit water consumption while maintaining reliable thermal performance. Additionally, we prioritize responsible sourcing of construction materials and continuously improve waste diversion through recycling and reuse programs.
Building a More Sustainable Digital Future
Cologix’s mission is to deliver infrastructure that supports both digital growth and environmental responsibility. Through efficient operations, renewable energy use and sustainable design, we help customers reduce their environmental footprint as they scale.
Looking ahead, we remain focused on supporting organizations that prioritize sustainability in their digital strategies. We invite businesses and technology leaders to partner with Cologix in choosing infrastructure solutions that contribute to a more sustainable future.
