Sustainability Masterclass | The Power of Green Advertising | 10 September 2025
THE POWER OF GREEN ADVERTISING: NAVIGATING THE FUTURE OF SUSTAINABLE MARKETING
As scrutiny of environmental marketing intensifies, the ability to communicate sustainability claims with clarity, accuracy and credibility has become essential.
This upcoming Masterclass will provide practical guidance on applying the core principles of the ICC Advertising and Marketing Communications Code, alongside the ASA CAP Code and the CMA’s Green Claims Code, to ensure that communications meet the rising expectations of both regulators and consumers.
It will explore how organisations can navigate the twin risks of greenwashing, overstating environmental credentials, and greenhushing, withholding them out of fear of scrutiny, by striking the right balance between transparency and substantiation. With the Digital Markets, Competition and Consumers Act 2024 now in force, and with new powers enabling the CMA to issue fines of up to 10% of global turnover, now is the time to ensure organisations are equipped to make lawful, substantiated, and globally aligned green claims.

Panel 2: Green Hushing: Why Some Brands Are Silent About Their Sustainability Achievements
Overview:
While greenwashing is often discussed, green hushing — the practice of underreporting or failing to communicate sustainability efforts — remains largely unaddressed. This panel will explore why many companies, particularly in complex sectors, hesitate to disclose their environmental progress. Experts will discuss how businesses can find a balance between transparency and caution, ensuring they communicate their sustainability achievements without overstating or underplaying them.
(The CMA plays a central role in ensuring that businesses adhere to the UK’s Green Claims Code, which covers not only misleading claims (greenwashing), but their role is particularly relevant to green hushing because the authority monitors whether businesses are withholding or underreporting environmental achievements, which can mislead consumers and create competitive disadvantages
Key Insights:
- Understanding the regulatory and reputational risks of green hushing and how the CMA’s Green Claims Code ensures companies are accountable for honestly communicating sustainability efforts.
- How to communicate sustainability achievements honestly, without overstating progress.
- Finding a balance between realistic environmental goals and consumer expectations.
