Iguá Saneamento S.A. is a Brazilian company that is dedicated to providing water and sewage services to municipalities in Brazil. The company was founded in 2012 and is headquartered in São Paulo. Iguá Saneamento S.A. has a strong commitment to sustainability and decarbonisation, and has implemented several initiatives to reduce its carbon footprint and promote the use of renewable energy.

One of the key initiatives that Iguá Saneamento S.A. has implemented is the use of corporate power purchase agreements (PPAs) for renewable energy. Corporate PPAs allow companies to purchase renewable energy directly from generators, often at a lower cost than traditional energy sources. This has allowed Iguá Saneamento S.A. to reduce its reliance on fossil fuels and promote the use of renewable energy in its operations.

In 2019, Iguá Saneamento S.A. signed a 10-year corporate PPA with a wind farm in Bahia, Brazil. This PPA will provide the company with 30% of its energy needs from renewable sources. The wind farm is expected to generate 1.2 million MWh of energy per year, which is equivalent to the energy consumed by 600,000 households. This PPA will help Iguá Saneamento S.A. to reduce its carbon footprint by 12,000 tonnes of CO2 per year.

In addition to corporate PPAs, Iguá Saneamento S.A. has also implemented several other initiatives to promote the use of renewable energy. The company has installed solar panels on the roofs of its water treatment plants, which provide a portion of the energy needed to operate the plants. In 2020, the company installed a 1 MW solar power plant in the city of Mauá, São Paulo. This solar power plant is expected to generate 1.5 million kWh of energy per year, which is equivalent to the energy consumed by 750 households.

Iguá Saneamento S.A. has also implemented several initiatives to reduce its energy consumption and improve its energy efficiency. The company has implemented a corporate energy management system, which allows it to monitor and manage its energy consumption in real-time. This system has allowed the company to identify areas where energy consumption can be reduced and implement measures to improve energy efficiency.

In addition to energy management, Iguá Saneamento S.A. has also implemented several initiatives to reduce its water consumption. The company has implemented a water reuse program, which allows it to reuse water from its treatment plants for non-potable purposes, such as irrigation and cleaning. The company has also implemented a leak detection program, which allows it to identify and repair leaks in its water distribution system.

Iguá Saneamento S.A. has a strong commitment to sustainability and decarbonisation, and has implemented several initiatives to reduce its carbon footprint and promote the use of renewable energy. The company's use of corporate PPAs for renewable energy, installation of solar panels, and implementation of energy and water management systems have allowed it to reduce its energy and water consumption, improve its energy efficiency, and promote the use of renewable energy.
