rezonanz Joins the Institutional Investors Group on Climate Change

rezonanz is now a proud member of the Institutional Investors Group on Climate Change (IIGCC)! As we join this leading network of investors working to drive climate action, we take another meaningful step toward empowering responsible investors to address the climate crisis through informed, impactful stewardship. As one of the five organizations coordinating Climate Action 100+, we've already benefitted from the IIGCC's work in establishing our global benchmark of sustainability-relevant votes for our global Voting for Sustainability ranking coming out November 27th.

The IIGCC's mission focuses on bringing the investment community together to make significant progress towards a net zero and climate resilient future by 2030. It was established in 2001 as a collaborative forum for pension funds and asset managers to address climate risks. Over its 20+ year history, IIGCC has grown into a pan-European network driving investor-led initiatives, such as the Paris Aligned Asset Owners and the Net Zero Asset Managers initiative, to support net zero ambitions. It provides tools, frameworks, and advocacy to help investors integrate climate strategies into their portfolios while advancing global climate policy and corporate engagement.

A Commitment to a Connected, Climate-Focused Investment Community

Becoming an IIGCC member underscores our commitment to integrating climate considerations into our work. The IIGCC provides a powerful platform for investors committed to:

• Supporting a net-zero economy by reducing carbon emissions across portfolios.
• Advocating for stronger climate policies at national and international levels.
• Engaging with companies on climate action and disclosure.

Empowering Our Mission

Joining IIGCC empowers rezonanz to enrich our services and tools for institutional investors on their climate journeys. Our membership strengthens our ability to advance climate-conscious investment practices through our stewardship software and advanced analysis tools, in support of IIGCC’s Climate Action 100+ and Net Zero Investment Framework initiatives.

With IIGCC’s objectives deeply embedded into our work, we aim to equip asset owners and managers with insights directly addressing climate risks and opportunities.

Expanding on our pilot projects in 2025

In Q4, we've launched two pioneering pilot projects focusing on voting and engagement to support all responsible investors:

1. Pension Funds Voting for Sustainability: We've empowered pension funds to benchmark their private voting records against the broader universe of over asset managers' and pension funds' voting records compiled as part of our global Voting for Sustainability ranking coming out on November 27th.
2. Collective Insight Engagement Pilot Initiative: We're advancing investor goals through anonymized collaboration. By enabling confidential disclosure of engagement records in exchange for mapping of those efforts across our database of over 40 other investors' public and proprietary engagements, we're unlocking by overcoming information asymmetries. Registration for participation in this first-of-its-kind pilot closes December 6th.

Both pilots are targeting streamlined information exchange for greater impact and alignment between asset owners and asset managers, a fundamental aspect of the IIGCC's external fund manager workstream. For more information on the IIGCC's important work addressing externally managed investments, see their guide on Net-Zero Strategies for Externally Managed Investments.

We look forward to contributing to and learning from the IIGCC and its over 400 members from 27 countries in our future initiatives. Together, we can drive meaningful change by unlocking investor action on climate change.
