Our purpose is to drive sustainable economic development for society to thrive. This guides all our activities and permeates our sustainability strategy.
In this sense, as an organization that is at the center of the financial and capital markets, we have a dual role:
- Engaging our stakeholders and encouraging best practices in the market by offering products and services that support our clients in the transition to a resilient and low-carbon economy;
- Conduct our internal activities through responsible management.
Considering the relevance of this agenda, our Social, Environmental, and Climate Responsibility Policy (PRSAC), approved by the Board of Directors, is aligned with the company’s strategic principles and provides guidance on the topic.
Through our internal management, we seek to align with the best sustainability practices existing in the market. This includes initiatives related to:
- Environment and climate change: our buildings are certified with ISO 14,001, and we have compensated 100% of the identified emissions from scopes 1, 2, and 3 since 2011.
- Corporate governance: we are listed in the Novo Mercado, have 100% independent members on the Board of Directors, and have ESG goals that impact the variable remuneration of the president and the entire company.
- Risk management: in addition to traditional corporate risk assessment, B3 also maps ESG risk factors and opportunities;
- Diversity, equity & inclusion: our internal practices permeate recruitment and selection processes, development programs, and mentoring focused on underrepresented groups, as well as active monitoring of the company’s diversity data and the establishment of goals in this regard.
- Private Social Investment: led by B3 Social, a non-profit association founded in 2007, responsible for integrating and coordinating our private social investment projects.
We believe in the value of partnerships and collaboration among market participants to expedite the ESG agenda. Therefore, we act as an associate, member, and/or signatory to various institutions and commitments focused on this agenda.
We became signatories of the UN Global Compact in 2005 and were the first stock exchange in an emerging country to commit to the Principles for Responsible Investment (PRI) in 2010. In 2012, we became a founding signatory of the Sustainable Stock Exchanges (SSE) initiative under the UN, and in 2024, we became an Official Supporter of the initiative.
B3 is also a member of the Thematic Climate Chamber of the Brazilian Business Council for Sustainable Development (CEBDS) since 2021; of the Green Finance Working Groups (LAB) of the CVM since 2021; and of the Executive Committee and the Working Committee of the Ibero-American Federation of Stock Exchanges (FIAB).
Additionally, we aim to democratize access to the capital market through financial education content designed for individual investors. This has been achieved through initiatives such as Bora Investir*, B3 Educação*, HUB B3*, and the individual investor relations website*
We also aim to induce companies in sustainability themes through our ESG products and services, which are distributed across three segments:
- Listed: we have the Corporate Sustainability Index (ISE B3), which for 20 years has sought to create an investment environment compatible with the demands of sustainable development. In addition to the ISE, we have 9 other ESG indices in our portfolio (ICO2 B3, IDIVERSA B3, ICBIO B3, IGPTW B3, Brazil ASG Index, IGC B3, IGCT B3, IGC – NM B3, and ITAG B3). In 2024, we launched B3 Green Equities, a designation for listed companies aimed at recognizing companies whose activities contribute to the green economy and the fight against climate change.
- Over-the-Counter (OTC): Every year, we have been developing and strengthening ESG products for this market as well, through platforms for 1) registration and trading of Carbon Credit Certificates (CBIOs), 2) registration of carbon credits, 3) identification of green, social, or sustainable (socio-environmental) bonds; 4) registration of Rural Product Notes (CPR Verde) and Structured Operations Certificates (COEs). Additionally, in 2023, we announced a partnership with ACX Group, one of the leading trading platforms for the global carbon credit market.
- Technology, Data, and Services: Aligned with our strategy for business expansion and diversification, we have developed the ESG Workspace platform. Launched in 2022, it integrates ESG information from companies listed on the Brazilian stock exchange and offers: consolidated data from sustainability reports of listed companies (Reports Data Module); information on financial instruments linked to sustainability registered in the over-the-counter market (Thematic Bonds Module); and ESG index data, including questionnaires from companies that participated in the ISE B3 process, as well as the ranking of companies in the index and information from the IDIVERSA B3 index.
Still within the scope of market induction, the ESG Annex will come into force in 2025, which stipulates that listed Brazilian companies must have at least one woman and one member from an underrepresented group on their boards of directors. The proposed mechanism is known as “comply or explain,” whereby companies must provide transparency to the market regarding the actions taken to meet these requirements or explain the reasons for non-compliance.
The text also proposes the establishment of diversity criteria in the procedures for the appointment of directors and members of the Board of Directors, as well as the inclusion of performance indicators linked to ESG themes or targets in the variable compensation policy of the companies’ management.
