The company has a long history of providing high-quality telecommunications services to its customers, and has been at the forefront of technological advancements in the industry. In recent years, Telstra has also been making significant efforts to reduce its carbon footprint and transition to renewable energy sources.

Decarbonisation is a key priority for Telstra, and the company has set ambitious targets to reduce its greenhouse gas emissions. In 2019, Telstra announced its commitment to net zero emissions by 2050, and has since been working towards this goal through a range of initiatives. One of the key ways in which Telstra is reducing its carbon footprint is through the use of renewable energy.

Corporate energy is another area of focus for Telstra, as the company seeks to reduce its reliance on fossil fuels and transition to cleaner sources of energy. Telstra has implemented a range of energy efficiency measures across its operations, including the installation of energy-efficient lighting, heating and cooling systems, and the use of energy-efficient equipment. The company has also invested in renewable energy projects, including wind and solar farms, to help meet its energy needs.

Corporate power purchase agreements (PPAs) are an important part of Telstra's renewable energy strategy. PPAs enable companies to purchase renewable energy directly from generators, often at a lower cost than traditional energy sources. Telstra has signed a number of PPAs with renewable energy providers, which has helped to increase the amount of renewable energy in its energy mix.

Renewable energy is a key focus for Telstra, and the company has set a target to source 50% of its energy needs from renewable sources by 2025. To achieve this goal, Telstra has invested in a range of renewable energy projects, including wind and solar farms. The company has also implemented energy efficiency measures across its operations, which has helped to reduce its energy consumption and carbon footprint.

Telstra's commitment to decarbonisation and renewable energy is not only good for the environment, but also makes good business sense.
