By Brazil Stock Guide – Brazil’s B3 exchange saw the issuance of 23 new ESG (Environmental, Social, and Governance) bonds in the first half of 2025, totaling R$ 10.35 billion. This push helped boost the overall stock of ESG-marked bonds to R$ 138.16 billion by June 30, 2025, marking a 7% increase compared to the year-end 2024 figure of R$ 128.75 billion. This growth highlights the continued demand for sustainable investment options, as more issuers and investors seek assets that combine financial returns with positive social and environmental impact.
According to data from B3’s ESG Workspace platform, debentures remain the dominant instrument for financing sustainable projects and meeting corporate ESG targets, representing 88% of total ESG bond issuance. These financial products are primarily used to fund environmental and social initiatives, or to support companies in achieving their ESG-linked goals, such as those associated with sustainability-linked bonds (SLBs).
Sector-wise, the ‘Electricity Services’ industry leads the pack, accounting for 32% of all ESG bond issuance, while other sectors maintain smaller, more varied shares. This distribution signals growing participation from diverse sectors of the Brazilian economy in the ESG space, with a notable focus on energy services.
Leonardo Betanho, B3’s Product superintendent, commented, “The continuous increase in the stock of ESG bonds reinforces the evolution and maturation of the Brazilian market toward a greener, more inclusive, and low-carbon economy.” This growing market in Brazil reflects a broader global trend of aligning financial returns with sustainability goals, making the country’s capital markets increasingly attractive for responsible investors.
