Colt DCS reported a 27% reduction in Scope 1, 2, and 3 greenhouse gas emissions since 2019, according to its 2025 Sustainability Report. The company achieved 100% renewable electricity for Scope 2 and a 90% renewable share across all scopes. It is targeting net zero by 2045 with SBTi-aligned goals. The improvements come from an updated Global Reference Design that uses lower-carbon materials, energy-efficient systems, and near-zero wastewater cooling. Colt aims for annualized PUE below 1.2 and waste diversion rates of 75% in construction and 90% in operations. Three sites have already achieved TRUE Zero Waste certification. The article notes broader pressure on data center sustainability. A UN report projects AI-related data centers could use 945 TWh of electricity and emit 399 million tons of CO2 by 2030. The IEA warns most new US data center demand through 2030 will be met by natural gas, slowing grid decarbonization.
