SSI 2026

2025 reshaped the sustainability landscape. After a year of global shocks, economic pressure and the rise of GenAI, people have entered 2026 feeling overloaded and unsure what to trust. They still care, but many are struggling to see which actions genuinely matter. For brands, this creates a choice: step back, or cut through with clarity, evidence and empathy.

Join us for Building effective sustainability marketing in 2026 webinar. This session explores what the new 2026 edition of Kantar’s Sustainability Sector Index reveals about where sustainability stands for people today and what that means for brands aiming to communicate credibly and effectively. We’ll focus on the “how”, using both landscape and sector learnings to show what good looks like and which levers matter most.

You’ll learn:

  • Where sustainability stands for consumers in 2026. What has shifted, what hasn’t, and how global uncertainty is shaping expectations, emotions and behaviours.
  • How sector dynamics shape opportunity. The issues that matter most in your category and Market Sophistication, helping you pick the right topics and build credible, relevant messages.
  • How to turn insight into action. A practical, insight led view of what brands should focus on in 2026 to build clear, confident and effective sustainability marketing.
