The standard

The CMA Green Claims Code and its guidance.

CMA green-claims and FMCG environmental-claims guidance

The CMA's follow-on work applying the Code — including its guidance for the fashion sector and its 2024 advice for the FMCG (food, drink and household) sector on environmental claims. Used for: the sector framing, the treatment of "sustainable/responsible/conscious" fashion language, and the offsets position. Freshness: FMCG guidance published 2024.

The law

The DMCCA 2024 — enforceable since 6 April 2025.

Digital Markets, Competition and Consumers Act 2024

The Act whose unfair-commercial-practices regime gives the CMA direct enforcement power — deciding a business has broken consumer law and fining up to 10% of global turnover without going to court. Those provisions came into force on 6 April 2025. Used for: the "high-risk / enforceable now" framing and the maximum-fine figure. Freshness: in force 6 April 2025; re-verified as current for this build. Read the Act on legislation.gov.uk:
