Navigating Greenwashing and Green Claims - 4-Part Mini Series, Part 1 - Cecilia Parker Aranha, Director, Competition and Markets Authority

In our 100th episode of Can Marketing Save the Planet we kick off our ‘4 part mini-series on greenwashing and navigating green claims’ with Cecilia Parker-Aranha, Director of Consumer Protection at the Competition and Markets Authority (CMA).

Cecilia joined us back in 2021, and so it was great to have her join us again to discuss the evolving landscape to provide an up to date understanding of where we are with greenwashing.

Since the publication of the Green Claims Code in 2021 significant progress has been made however, challenges remain. Cecilia tells us that since we last spoke, the CMA has taken action against misleading claims in sectors like fashion and fast-moving consumer goods prompting businesses to reassess their environmental messaging. She highlights how technology can be used to aid businesses in tracking supply chain data, but the human part remains crucial to ensure claims are accurate and not misleading.

We discuss how consumers are increasingly distrustful of green claims and how now is the time for organisations to focus on making sure what they are saying is accurate and evidence-based. Cecilia again explains that the CMA’s role is not to punish but to guide organisations toward compliance through education and support. However, under the Digital Markets, Competition and Consumers Act, everyone needs to be aware that the CMA can now impose fines directly and these can be up to 10% of global turnover for breaches and - breaches including misleading green claims. Cecilia explains, “so from April this year (2025), we'll have the power to reach our own decisions on whether or not a business has breached consumer law. The second thing is that at the moment there aren't any financial penalties for breaches of consumer law, at least those pursued through the civil route. Again, from April this year, it will be possible for the CMA to impose financial penalties on businesses who break the law.”

Cecilia stresses the importance of collaboration between marketing and sustainability teams to ensure there is clear, accurate communication. She recommends that Marketers test claims with consumers to avoid misinterpretation and ensure transparency. Sharing so much knowledge and advice in this episode Cecilia believes Marketers should start by measuring their impact and build claims from solid evidence. And, this isn’t just for those organisations operating in the UK, and as many organisations sell into other countries, she advises ensuring alignment with global standards like the EU Green Claims Directive.

Tune in and listen as we talk to Cecilia about:

• The current green claims landscape as we progress through 2025
• What organisations and Marketers should be thinking about when considering making green claims
• Where to go to stay informed and up to date
• Digital products passports and how they align with green claims
• The use of technology in supporting green claims
• The need for Marketing teams to work cross-functionally
• Why it’s important for organisations to talk about what they are doing
• For resources check out the CMA’s Green Claims Code and on their website you’ll find lots of information, such as - what has happened in cases and what advice and agreements were reached. These real world cases further provide guidance on the changes organisations need to consider to ensure they are being responsible when making green claims.
• More in this mini-series to follow with conversations with the ASA, ClientEarth and Fanclub PR. Stay tuned.
