Coalition launches standards for greener AI data centres

Nine building and climate organisations have launched the Greening AI Data Centres Coalition to set sustainability benchmarks for data centre development.

The coalition includes the Building Research Establishment, Climate Bonds Initiative, German Sustainable Building Council, Global Real Estate Sustainability Benchmark, Green Building Council of Australia, Green Building Council South Africa, Indian Green Building Council, U.S. Green Building Council and World Green Building Council.

Its initial work will focus on two areas: an internationally aligned framework for environmental and social performance standards for data centres, covering energy, carbon, water, waste, biodiversity and community impact; and support for green finance instruments, including green bonds and sustainability-linked loans, for projects that meet those standards.

The launch comes as demand for computing infrastructure rises alongside the spread of artificial intelligence. The organisations behind the initiative say cities are under growing pressure from data centre expansion because of concerns over electricity and water use, effects on local utility costs, noise, and the limited number of long-term jobs such facilities typically create.

Data centres account for about 1.5% to 2% of global electricity consumption, according to figures cited by the coalition. The International Energy Agency expects that demand to more than double by 2030.

Water use is also coming under greater scrutiny. In some regions, the organisations say, certain facilities consume as much water as a small city, adding pressure to already stretched local supplies.

Standards Push

The coalition wants to establish a clearer definition of what qualifies as a green data centre as investor interest in the sector grows. That includes creating benchmarks to help investors, operators, communities and policymakers distinguish between projects with lower environmental impacts and those that risk overstating their sustainability credentials.

By setting common criteria, the group also aims to address a fragmented landscape in which data centre developers and financiers face different standards across markets. A more consistent framework could influence both capital allocation and project design, especially in regions where power constraints and water stress are becoming more pronounced.

The launch reflects a broader debate over the environmental cost of the AI boom. New data centres are being proposed and built rapidly to meet demand for cloud services and AI workloads, but they also require large amounts of energy for computing and cooling.

If those facilities rely heavily on fossil fuel-based grids or draw from scarce water resources, they could complicate wider decarbonisation efforts. That tension has made data centres a growing focus for urban planners, utilities, investors and sustainability assessors.

Finance Angle

The coalition's emphasis on financial tools is notable because green bonds and sustainability-linked loans are becoming more common in property and infrastructure funding. A recognised set of criteria for data centres could give lenders and investors a clearer basis for deciding which projects qualify for such funding.

That may matter as operators seek large sums to expand server capacity and related infrastructure. It could also shape how developers approach site selection, energy sourcing, cooling systems and community impact if access to finance becomes tied to measurable environmental and social standards.

The founding members span building certification, sustainability benchmarking and green finance. Together, they give the initiative reach across property markets, institutional investors and standards bodies in several regions.

Peter Templeton, president and chief executive officer of the U.S. Green Building Council, outlined the rationale for the group's formation.

"We are proud to be a founding member of this coalition to accelerate sustainable design and operations in data centers worldwide. As a strategic asset class, data centers are central to technological innovation and economic growth. Through this coalition, we are committing our collective expertise to balancing this growth with responsible development that protects energy affordability, local resources, and quality of life," Templeton said.
