Green bonds are becoming one of the main financing tools for sustainability projects, both in Brazil and worldwide. They emerged as a viable solution to unite financial returns with positive environmental impact. Initially created by the World Bank in 2008, these bonds are directed exclusively to projects aimed at reducing greenhouse gas emissions, protecting biodiversity, and promoting energy transition, among other environmental topics.
In Brazil, the issuance of green bonds is still a relatively new market but is growing rapidly. According to data from the Central Bank, the country accounts for just over 1% of global sustainable bond issuances, with volumes totaling approximately USD 20 billion between 2020 and 2021. Internationally, Brazil ranks second in Latin America, behind only Chile. Non-financial companies, mainly from the pulp and paper, food, and beverage sectors, lead the issuance of green bonds in the country.
These bonds have proven particularly attractive to investors looking to align their portfolios with ESG (Environmental, Social, and Governance) goals, as they offer transparency and guarantees that the funds will be applied to green projects, such as renewable energy, clean transportation, and environmental conservation. An example is the issuance of bonds by BNDES, which has already raised USD 1 billion internationally to finance wind and solar energy projects. In 2020, the bank became the first Brazilian institution to issue a Green Financial Letter in the domestic market.
A recent study shows that green bonds will be one of the main strategies for companies in Brazil to meet their ESG goals. According to the research, companies are increasingly committed to financing projects that promote energy efficiency and the transition to clean energy sources, especially with growing demand from consumers and investors for sustainable business practices.
Globally, the importance of green bonds was reinforced at COP28, where world leaders agreed to accelerate the implementation of climate goals for 2030. The International Energy Agency (IEA) emphasized that issuing green bonds will be critical to financing the energy transition needed to limit the global temperature increase to 1.5°C. For this to happen, countries must adopt more aggressive policies and attract investments that will allow the expansion of technologies such as solar, wind, and electric vehicles.
Despite the evident benefits, the issuance of green bonds is not without risks. One of the main challenges is the financial risk associated with exchange rate fluctuations, as many of these bonds are issued in US dollars. However, experts argue that Brazil has robust international reserves, which can mitigate potential negative impacts, such as the depreciation of the real. Nonetheless, the risk for investors and issuers remains, particularly in a globally unstable economic scenario.
In addition to financial risks, there is also concern about “greenwashing,” where companies promote superficial or low-impact environmental initiatives to benefit from a reputation for being sustainable. For this reason, the certification of green bonds by independent entities is a crucial requirement to ensure that funds are being directed correctly.
Another important aspect is the positive impact generated by green bond issuances. According to the Climate Bonds Initiative, the energy, transportation, and sustainable building sectors are the biggest beneficiaries of these funds, contributing more than 80% of global issuances. In Brazil, most issuances occur through debentures, with a focus on the electricity sector, which uses these funds to expand its renewable energy operations.
In the near future, the green bond market is expected to continue growing, driven by favorable public policies and pressure from investors and consumers for more responsible business practices. The issuance of new types of sustainable bonds, such as Green Financial Letters, and the expansion of the use of funds for social projects, such as health and education, promise to further diversify this market.
Thus, green bonds are consolidating as a central piece in the global strategy to combat climate change, allowing companies and governments to finance the transition to a low-carbon economy while offering competitive financial returns to investors.
