An industry-wide signal of environmental performance

GreenMark evaluates how digital and AI services actually behave in practice — how efficiently they are designed, configured, released, and operated — and identifies opportunities to reduce environmental impact while maintaining performance, resilience, and security.

GreenMark is governed by the GreenMark Alliance and delivered only by licensed certification bodies operating under defined scheme rules and oversight.

GreenMark delivers value in three connected ways:

Independent certification demonstrating credible digital sustainability performance
Structured insight into product-level efficiency and improvement opportunities
Education and capability-building to support sustained improvement

Together, these ensure GreenMark is not a one-off assessment, but a mechanism for embedding sustainability into digital product management.

GreenMark is aligned to supporting UK government technology procurement requirements and provides data for all purchasing teams to support their management of supply chain and Scope 3 emissions.

Trust and Sustained Improvement

GreenMark is owned and governed by The GreenMark Alliance.

Certification is delivered only by licensed organisations operating under defined scheme rules, licence conditions, and oversight.

GreenMark supports a pathway approach that can be embedded into an organisation's technology delivery methods and approaches.

Certification reflects current performance while highlighting opportunities for improvement during the certification period. Re-certification enables progress to be demonstrated over time.

The GreenMark is a signal of sustained environmental management and performance.
