Climate Action for PE Portfolios: A Swiss Case Study

Published on Oct 24, 2025

Challenge

Investor expectations were rising, with an anchor Limited Partner (LP) calling for credible evidence of portfolio climate action and alignment with the Paris Agreement. Yet portfolio companies were at very different stages of maturity, making a prescriptive “net zero” pledge unrealistic and risking inconsistent progress.

Solution & methodology

dss+ worked with the client to design a practical, scalable approach tailored to its portfolio profile:

  • Developed a Climate Transition Framework aligned with Net Zero Investment Framework (NZIF) principles and embedded across the investment lifecycle.
  • Assessed 100% of portfolio companies against transition preparedness criteria to identify gaps and priorities.
  • Designed tailored Climate Action Roadmaps for each portfolio company, proportionate to maturity and sector context.
  • rained the investment team to apply the framework consistently in sourcing, due diligence, and engagement.
