Mirova Research Center and Sweep Launch Call for Expression of Interest for the Creation of a Corporate Contribution Index to Carbon Neutrality

Published on 03/04/2025 Press releases
  • Mirova Research Center and Sweep, an online platform for managing carbon and ESG data, are partnering to launch a Call for Expression of Interest aimed at creating an index to measure the contribution of companies to global carbon neutrality. 
  • The Corporate Climate Contribution Indicator (CCCI) will enable a holistic assessment of companies' decarbonization efforts and their progress toward achieving net-zero emissions by 2050. 
  • The CCCI’s methodology will be presented at the 30th Conference of the Parties (COP30) in Bélem, Brazil, in November 2025.

Why a Corporate Climate Contribution Index? 

Companies play a crucial role in the fight against climate change, as they influence not only their own emissions but also those within their value chains. Although thousands of companies have adopted Net Zero1 targets, commitments vary across sectors, and current assessment frameworks often focus solely on operational emissions. The CCCI aims to evaluate these contributions comprehensively, considering three main levers: 

  1. Direct Decarbonization: Reduction of greenhouse gas (GHG) emissions across all operations and the value chain, aligning with science-based targets consistent with a 1.5°C warming scenario. 
  2. Indirect Decarbonization: Assessment of emissions reductions enabled by a company's products and services, quantified through avoided or negative emissions. 
  3. Climate Financing: Financial contributions to carbon reduction and capture projects outside the value chain, including the purchase of high-quality carbon credits. 

Mirova Research Center and Sweep acknowledge that the relative impact of each lever on a company's climate contribution varies based on numerous factors, including geography and sector. Therefore, the CCCI will provide a dynamic tool to evaluate these essential levers for action. For instance, a company that supplies critical components for battery production—essential for the decarbonization of transport—should be valued for this contribution, not just for its own decarbonization efforts. As for financial institutions, they are expected to demonstrate their ability to finance the transition to a low-carbon economy and to increase carbon sequestration through nature-based solutions.  

Benefits for Companies and Investors, Supporting the Transition 

For companies, the ICCE will provide an assessment tool that will allow them to determine whether or not they are at the right level of contribution to Net Zero in light of their role in society. For investors, the index will provide a solid foundation for evaluating the climate performance of companies, helping to detect instances of greenwashing and establish clear sector benchmarks. By integrating these elements into their analyses, investors will be better equipped to guide their decarbonization strategies and maximize the impact of their shareholder engagement policies.

The CCCI will represent a significant advancement in our approach to shareholder engagement by enabling us to engage in dialogue on the key action levers based on a transparent methodology. This index can also serve as a compass for investment strategies to enhance their performance — and potentially their climate impact.

Co-Head of Mirova Research Center

The CCCI aims to bring together all of the essential methodological building blocks of climate action which are available today. By putting forward a positive narrative, based on science and applicable to all sectors, this index will make it possible to highlight the societal role of businesses, and restore the reputation of Corporate Social Responsibility which has been so maligned in recent times.

Renaud Bettin
VP of Climate Action, Sweep

The Call for Expression of Interest aims to mobilize the most effective global actors in climate action. Applications can be submitted until April 4,2025. The methodology will be developed transparently and will remain free and accessible to all. It will be presented at the 30th Conference on Climate Change (COP 30), which will take place in November 2025 in Belém, Brazil.
