Vauban Infrastructure Partners and Carbone 4 Announce a Joint Initiative
Vauban Infrastructure Partners ("Vauban "), a long-term investor in critical infrastructure, and Carbone 4, a consulting firm specializing in decarbonization strategies and climate change adaptation, are pleased to announce a new partnership.
In a world transitioning toward a resilient, low-carbon economy, it is crucial that infrastructure financing stakeholders have access to shared, operational tools to help achieve carbon neutrality and manage climate risks. In light of this, Vauban and Carbone 4 have decided to form a partnership dedicated to developing a methodology for analyzing physical climate risks in North America.
This joint initiative is based on the CIARA (Carbon Impact Analytics for Real Assets) methodology, which aims to develop key performance indicators addressing the following two climate-related concerns:
- Decarbonization: Aligning Infrastructure Portfolios with the Paris Agreement.
- Business Resilience: Managing Climate Risks to Vulnerable Assets More Effectively.
Laurent Morel, a partner at Carbone 4, explains: "This methodology draws on Carbone 4’s fifteen years of experience in the field of physical risks related to climate change. It enables investors to identify potential risks to their portfolios. Infrastructure is particularly vulnerable to the impacts of climate change due to its long lifespan. Conducting a CIARA analysis is the first essential step for investors who wish to implement a climate change adaptation strategy."
Gwenola Chambon, The CEO and co-founder of Vauban Infrastructure Partners adds: “Vauban is already committed to being a pioneer in the implementation of ESG in the European infrastructure sector, notably through its annual research conducted in collaboration with industry experts, academics, and all of its stakeholders (1), as well as through initiatives such as the UN PRI Infrastructure Committee and The Initiative for Climate International (iCI). Developing this new partnership with Carbone 4 will enable us to align the methodology for calculating the climate impact of our assets across our global portfolios, marking another significant step forward in advancing our strategic climate plans across our entire portfolio. “This historic partnership will enable Carbone 4 to expand its scope of analysis to all of North America. This is a major step forward in the ongoing fight against climate change, not only for us but for the entire community.”
