AES Tietê reaffirmed the certification of Green Bonds (green debentures) in 2020 through the seal of the Climate Bonds Initiative (CBI), an international organization that promotes the bond market for investments in solutions on climate change, having socio-environmental performance assessed by SITAWI Well and check from VigeoEiris. With this, the company achieves this certification for the second consecutive year.

Green debentures are debt securities whose resources are used to finance projects linked to sustainability, such as renewable energy infrastructure projects, which bring benefits to the environment and contribute to mitigating the effects of climate change and the use of natural resources, among them reducing emissions.

In 2019, AES Tietê became the first Brazilian company to issue green bonds of solar project in Brazil, which resulted in the raising of R $ 820 million, the proceeds of which were allocated to the construction of the Guaimbê and Ouroeste solar plants, being the first major investments in solar energy in the state of São Paulo.

Good governance practices and constant monitoring of GBP (Green Bond Principals) indicators were essential for this recertification. These indicators show compliance with labor, environmental, regulatory, financial and good conduct standards with the community, ensuring that the resources allocated are aligned with the GBP's eligibility specifications, as well as with good international practices.

"This pioneering spirit combined with management with sustainable practices reinforces AES Tietê's commitment to global corporate governance parameters and its alignment with ESG (Environmental, Social and Governance) practices," said Clarissa Sadock, Vice President and Investor Relations Director.

The company's pioneering spirit was a milestone in the Brazilian green finance market as it further encouraged investments for sustainable development in the country.
