Sierra Nevada Brewing Co. is a craft brewery located in Chico, California, United States of America. Founded in 1980 by Ken Grossman, the company has grown to become one of the largest craft breweries in the country. Sierra Nevada Brewing Co. is committed to sustainability and has implemented several initiatives to reduce its environmental impact.

Decarbonisation is a key focus for Sierra Nevada Brewing Co. The company has set a goal to reduce its carbon footprint by 50% by 2025. To achieve this goal, the company has implemented several measures to reduce its energy consumption and increase its use of renewable energy. One of the key initiatives is the installation of a 2-megawatt solar array at its Chico facility. The solar array generates approximately 20% of the facility's electricity needs and has helped the company reduce its carbon emissions by over 2,000 metric tons per year.

Sierra Nevada Brewing Co. has also implemented a corporate energy program to reduce its energy consumption. The program includes energy audits, energy-efficient lighting, and HVAC upgrades. The company has also implemented a comprehensive recycling program to reduce waste and promote sustainability.

Corporate power purchase agreements (PPAs) are another key initiative for Sierra Nevada Brewing Co. The company has entered into several PPAs to purchase renewable energy from wind and solar farms. The PPAs allow the company to purchase renewable energy at a fixed price, which helps to stabilize its energy costs and reduce its carbon footprint. The company has also partnered with local utilities to purchase renewable energy credits (RECs) to offset its carbon emissions.

Renewable energy is a key focus for Sierra Nevada Brewing Co. The company has set a goal to source 100% of its electricity from renewable sources by 2025. In addition to its solar array and PPAs, the company has also installed a small hydroelectric generator at its Chico facility. The generator uses water from a nearby canal to generate electricity, which helps to reduce the company's reliance on grid electricity.

Sierra Nevada Brewing Co. has also implemented several water conservation initiatives. The company has installed water-efficient fixtures and equipment, implemented a comprehensive water recycling program, and partnered with local farmers to use recycled water for irrigation. The company has also implemented a comprehensive wastewater treatment program to ensure that its wastewater is treated to the highest standards before being discharged.

In addition to its sustainability initiatives, Sierra Nevada Brewing Co. is committed to supporting local communities. The company has donated over $15 million to local non-profit organizations, and its employees have volunteered over 100,000 hours in the community. The company also sources many of its ingredients from local farmers and suppliers, which helps to support the local economy.

Sierra Nevada Brewing Co. has received numerous awards and recognition for its sustainability initiatives. The company has been recognized by the U.S. Environmental Protection Agency (EPA) as a Green Power Partner, and has been named one of the top 10 greenest breweries in the country by the Green Business Network.

In conclusion, Sierra Nevada Brewing Co. is a leader in sustainability in the brewing sector. The company's commitment to decarbonisation, corporate energy, corporate PPA, and renewable energy has helped to reduce its environmental impact and promote sustainability.
