The ICO2 B3 index is reviewed in partnership with BlackRock and BNDES and expands the number of eligible companies.

B3 has reviewed the efficient carbon index (ICO2 B3) in partnership with the Brazilian Development Bank (BNDES) and BlackRock asset manager. The chief goal of this initiative is to expand the number of companies eligible for the index, seeking to further align the products offered by B3 with the demand for investments related to the transition to a low-carbon economy. 
The new criteria are focused on selecting companies based on their efficiency and quality of greenhouse gas (GHG) emissions management, taking into account the coefficient between GHG emissions and gross revenue, along with a score related to climate change management. The new criteria also include: 

- Be part of the Brazil Broad-Based Index (IBrA B3).
- Validate and authorize the use of data on GHG emissions and management practices in the ESG Workspace.
- Be within the 75% group of companies that emit the least GHGs in relation to revenue.
- Have a GHG emissions management score higher than that of its sector.
- Adopt at least four management practices considered in the calculation of the GHG emissions management score. 

The ICO2 B3 index review represents an opportunity for Brazilian companies to further engage in the transition to a low-carbon economy. Furthermore, the measure contributes to strengthening awareness about the importance of sustainability in the financial market, considering investors' growing demands for products aligned with ESG (Environmental, Social and Governance) principles.
