AT&T Inc is a leading telecommunications company in the United States of America that provides wireless services, internet services, and entertainment services to millions of customers. The company has a strong commitment to sustainability and decarbonisation, and has set ambitious targets to reduce its carbon footprint and transition to renewable energy sources.

One of the key areas of focus for AT&T is corporate energy management. The company has implemented a range of initiatives to reduce its energy consumption and increase energy efficiency across its operations. For example, AT&T has invested in energy-efficient technologies such as LED lighting, and has implemented energy-saving measures such as using natural light to reduce the need for artificial lighting.

In addition to reducing its energy consumption, AT&T is also committed to sourcing renewable energy to power its operations. The company has set a target to source 50% of its electricity from renewable sources by 2025, and has already made significant progress towards this goal. In 2019, AT&T signed a corporate power purchase agreement (PPA) for 300 MW of wind energy, which will be used to power its operations in Texas.

Corporate PPAs are an important tool for companies like AT&T to support the development of renewable energy projects and reduce their carbon footprint. By entering into long-term contracts to purchase renewable energy, companies can provide a stable revenue stream for developers, which can help to attract investment and accelerate the growth of the renewable energy sector.

AT&T has also implemented a range of other initiatives to support decarbonisation and renewable energy. For example, the company has set a target to deploy 60,000 electric vehicles in its fleet by 2025, which will help to reduce emissions from its transportation activities. AT&T has also invested in renewable energy credits (RECs), which represent the environmental attributes of renewable energy generation and can be used to offset emissions from non-renewable sources.

Overall, AT&T is a leader in the telecommunications sector when it comes to sustainability and decarbonisation. The company has set ambitious targets to reduce its carbon footprint and transition to renewable energy sources, and has implemented a range of initiatives to achieve these goals. By investing in energy efficiency, sourcing renewable energy, and supporting the growth of the renewable energy sector through corporate PPAs and other initiatives, AT&T is demonstrating its commitment to a more sustainable future.
