On 24th June, Brand Finance and Ad Net Zero hosted an exclusive panel discussion during London Climate Action Week, exploring how brands can build and maintain strong sustainability perceptions in an era of increasing scrutiny and greenhushing.
The event featured the latest findings from the Brand Finance Sustainability Perceptions Index 2026, revealing the brands perceived to have the strongest commitment to sustainability globally, the evolving role of sustainability in driving consumer demand, and the significant value that sustainability perceptions create for the world's biggest brands.
This year's research highlighted a growing gap between sustainability performance and perception. As organisations continue to advance their ESG strategies, many are becoming more cautious about communicating their progress publicly—a trend often described as greenhushing.
Following the presentation of the findings, an expert panel discussed how brands can navigate increasing scrutiny, communicate their sustainability efforts with credibility, and ensure meaningful action translates into stronger reputation and lasting trust.
