The U.S. Drug Enforcement Administration (DEA) is a federal law enforcement agency operating within the United States Department of Justice. The agency is responsible for enforcing controlled substance laws and regulations, as well as investigating and dismantling drug trafficking organizations. The DEA was established in 1973 and has since been at the forefront of the nation's efforts to combat drug trafficking and abuse.

As a federal agency, the DEA is subject to various regulations and policies related to decarbonisation and corporate energy. The agency has taken steps to reduce its carbon footprint and increase its use of renewable energy sources. One of the ways the DEA has achieved this is through the implementation of a corporate power purchase agreement (PPA) for renewable energy.

A corporate PPA is a contractual agreement between a company and a renewable energy provider, in which the company agrees to purchase a certain amount of renewable energy from the provider over a set period of time. This allows the company to reduce its carbon footprint and promote the use of renewable energy sources, while also providing a stable source of energy for its operations.

In 2019, the DEA signed a 20-year corporate PPA for renewable energy with a wind farm in Oklahoma. The agreement will provide the agency with 40% of its electricity needs from renewable sources, reducing its carbon footprint by an estimated 5,000 metric tons of CO2 emissions per year. This is equivalent to removing approximately 1,000 cars from the road each year.

The DEA has also implemented various other measures to reduce its carbon footprint and promote sustainable practices. The agency has implemented energy-efficient lighting and HVAC systems in its facilities, as well as utilizing renewable energy sources such as solar panels and geothermal systems. The agency has also implemented a recycling program to reduce waste and promote sustainable practices.

In addition to its efforts to reduce its carbon footprint, the DEA is also committed to promoting corporate energy efficiency. The agency has implemented various measures to reduce energy consumption in its facilities, such as implementing energy-efficient lighting and HVAC systems, and utilizing energy management systems to monitor and control energy usage.

The DEA has also implemented various policies and programs to promote sustainability and reduce its impact on the environment. The agency has implemented a green procurement policy, which requires the use of environmentally friendly products and services in its operations. The agency has also implemented a sustainable transportation policy, which encourages the use of alternative transportation methods such as public transportation and carpooling.

Overall, the DEA is committed to promoting sustainable practices and reducing its impact on the environment. The agency has implemented various measures to reduce its carbon footprint and promote the use of renewable energy sources, as well as promoting corporate energy efficiency and sustainable practices. Through these efforts, the DEA is setting an example for other federal agencies and organizations to follow in their efforts to promote sustainability and reduce their impact on the environment.
