“Simplified ESRS” is triggering a big question in the market: does this mean less double materiality?

Short answer: no. The real story is more important. The draft Simplified ESRS doesn’t weaken the double materiality assessment (DMA), it re-centres it. The shift is away from exhaustive, time-heavy scoring across everything, and toward clearer, faster, more defensible judgement that can stand up to assurance.

That’s exactly what we’ll unpack in this 30-minute session: Learn how Simplified ESRS shifts double materiality from exhaustive scoring to defensible judgement.

Join Tim (Chief Impact Officer at Socialsuite) and Michael Littenberg (Partner at Ropes & Gray) for a practical conversation on what’s changed and what that means for your next DMA cycle.

We’ll cover:

  • How the top-down approach is now explicitly supported
  • How to separate clearly material, clearly immaterial, and the grey zone
  • What still requires deeper assessment and targeted engagement
  • The minimum evidence likely to satisfy assurance
  • How to document DMA decisions with less boilerplate and more clarity

If you’re running, advising on, or preparing for an ESRS-aligned DMA, you’ll leave with a sharper way to simplify without increasing risk; and a clear sense of what to prioritise in 2026 planning.
