Taesa Sustainability


Targets and Commitments

In harmony with our mission, vision and values, and always seeking to continuously improve our performance and adopt best practices, we seek to engage in initiatives and commitments that lead us in this direction, such as those described below.

Sustainability Project

In 2020, TAESA consolidated its growth trajectory in the Sustainability Project, strengthening the relevance of the topic in its various initiatives, with the objective of making the Company a benchmark in the area in the Electric Power Transmission sector in Brazil. To this end, a continuous improvement project has been as prepared, with the aim of implementing several actions on the following topics: social, environmental, governance, management, communication, policies and systems, in a period of up to 36 months.

Main actions to promote evolution of Environmental, Social and Governance (ESG) topics inside and outside the Company include:

  • Survey of the inventory of greenhouse gases (GHG) according to the GHG Protocol methodology.
  • Targets for reducing the consumption of fossil fuels in the fleet.
  • Inclusion of environmental and social clauses/assumptions in contracts with suppliers.
  • Preparation of this social and environmental report based on the practices of the Global Reporting Initiative (GRI).
  • Creation of a Diversity Program.
  • Great Place to Work Certification.
  • Signatory of UN Global Compact by committing to the 2030 Agenda regarding the Sustainable Development Goals.
  • Signing of the UN Women’s Empowerment Principles (WEPs)
  • ESG indicators dashboard available on the Investors Relations (IR) website.

Based on a consultation with stakeholders, we were able to revisit the materiality process whereby the relevant topics are identified for not only management but also communication, presented throughout the sustainability report, and detailed in their performance and form of management according to the (Global Report Initiative).

United Nations Global Compact

Aiming to corroborate its contribution to sustainability, TAESA joined the United Nations Global Compact in 2019, an initiative that promotes a dialogue between companies, corporations and UN bodies on social and environmental responsibility policies.

The Compact is currently the world’s largest corporate sustainability initiative, with over 13,000 members spread across 160 countries. The central idea of the Global Compact is to promote the social dimension of globalization. To this end, this initiative seeks to engage the international business community in ten principles related to Human Rights, decent work, the environment and the fight against corruption.

Gender equality: a commitment from all of us.

TAESA has adhered to the Women’s Empowerment Principles (WEPs), known as the seven principles of women’s empowerment, an initiative of UN Women. Becoming a signatory to this movement reinforces TAESA’s importance and commitment to supporting and promoting gender equality and women’s empowerment in the workplace, market and community. Below are the seven principles:

High-level corporate leadership

Fair treatment of all women and men at work, without discrimination

Worker health, safety and well-being

Education and training for professional development

Enterprise development, supply chain and marketing practices

Community initiatives and advocacy

Measurement and reporting

TAESA is proud of the talent and competence of its employees, and will increasingly work to contribute toward inclusion and diversity.

First place in Great Place to Work (GPTW) Energy 2021

With the conviction that people are Taesa’s greatest asset, in 2020 and 2021, the company was recognized with the 1st place in the GPTW Energy (2020 and 2021) Highlight – Cut, Generation, Distribution and Transmission award. Annually, the Company conducts an organizational climate survey in partnership with GPTW to measure the level of engagement and satisfaction of the teams. Last year, TAESA reached 94 points in the survey, earning the “Best Company to Work for” certification and reaffirming its position as a benchmark in the sector.


Committed to sustainable growth, TAESA strives toward operational excellence, ensuring profitability and financial discipline, incorporating sustainability criteria, policies and operational practices that augment the company’s competitiveness, while promoting the improvement of socioeconomic conditions in communities, such as a shared value.

We adopt the best financial practices and instruments, as well as investment and financing decisions. By doing so, we promote positive economic impacts that contribute toward boosting and/or leveraging of the local economy (through the installation of assets and infrastructure, creation of jobs, etc.) and all the associated benefits, providing for improvement in people’s quality of life.

This is a win-win relationship, whereby the company – in promoting local development by driving the economy and developing programs – shares value with society and acts with environmental responsibility.

These initiatives facilitate access to financing with favorable counterparts (lower interest rates), which enables the expansion of activities and assets, such as the issuance of green bonds.


Green Bonds

Green Bonds, also known as Climate Bonds, are securities issued to raise funds for investments in projects that have sustainability-oriented premises, through socioenvironmental controls and the respective mitigation of their impacts.

In a historical context, the world’s first Green Bond was issued by the World Bank in November 2008, giving rise to a sustainable process in the capital market. The issuance of this first paper demonstrated to the world how it was possible to relate sustainability with profitability.

According to the guidelines of these securities, which use the Green Bond Principles (GBP) as a methodology, it is acknowledged that transmission lines in Brazil contribute to the flow and transmission of renewable energy in the National Interconnected System (SIN).

Proceeds from the issuance of green bonds for TAESA will be used for future payments and reimbursement of project costs related to electricity transmission. These assets bring environmental benefits, since their construction will increase the availability of the National Interconnected System (SIN) for renewable energy;

Reinforcing our commitment to transparency, we joined the Inter-American Development Bank’s (IDB) Green Bond Transparency Platform (GBTP) in August 2021, designed to promote transparency in the green bond market in Latin America and the Caribbean. Through GBTP, it is possible to harmonize and standardize the reports on green bonds and allow the market, in general, to analyze the resources of the securities invested and what environmental performance has been achieved. This action provides the capital market with relevant information on the Company’s environmental performance, which makes it even more interesting to new and current investors.

The environmental benefit generated by the projects is associated with the increase in the volume of non-conventional renewable energy transmission (wind, solar, biomass thermoelectric plants, and small hydros). This benefit will be demonstrated by the changes in the “Indicator of transmission services provided to Green Users”.
