More than 40 companies and trade organizations tied to the cloud and data center industry have formed the European-based Climate Neutral Data Centre Pact in a self-regulatory move to make data centers across that continent climate neutral by 2030.

The agreement establishes measurable targets signees must meet in order to drive their respective data centers toward climate neutral footing. Targets include the purchasing of carbon-free energy, water conservation, reuse and repair of servers, and heat recycling.

The targets were developed in cooperation with the European Commission (EC) to support the European Green Deal, which is focused on making Europe climate neutral by 2050, and the European Data Strategy that is focused on making data centers climate neutral by 2030. The Data Centre Pact goals will be monitored by the EC twice per year.

Signees to the agreement include Amazon Web Services (AWS), Equinix, Google, NTT, Aruba, and Scaleway.

The move continues what has been an increased push by data center and cloud providers to clean the significant carbon footprint of their operations. This includes a number of hyperscalers pledging to hit carbon-neutral goals by the 2030 timeframe.

Google, for instance, last year pledged to run all of its worldwide data centers and corporate campuses on 100% carbon-free power by 2030. The new pledge builds on the cloud giant’s previous achievement of matching its energy use with 100% renewable energy by 2017.

And Microsoft, which was notable absent from the latest news, has been exploring underwater data centers that take advantage of the ocean’s natural cooling capabilities.
