Charles River Laboratories Achieves 100% Renewable Electricity Usage Globally

Charles River Laboratories International, Inc. (NYSE: CRL) today announced it has reached 100 percent renewable electricity across all of its global sites as of the first quarter of 2024, significantly ahead of the original target date. In 2020, Charles River became one of the first 300 members of RE100, a global corporate renewable energy initiative, and committed to operating on 100 percent renewable electricity globally by 2030. Today, Charles River joins a small group of leading companies that have achieved this goal organization-wide in accordance with RE100's standardized reporting criteria¹.

In efforts to reach its renewable electricity target, Charles River has:

• Executed two critical virtual power purchase agreements (vPPAs) in the United States and Europe. In 2020, the Company initiated a 15-year contract with Deriva Energy for a 102-megawatt solar vPPA located in Texas, which, as of January 2023, provides 100 percent of its North American electric power requirements with clean, renewable energy. Further, in 2023, Charles River's 12-year, 30-megawatt wind power vPPA went live, which is a partnership with Spain-based Repsol, a multi-energy company, and covers the organization's entire European electricity load.
• Partnered with leading organizations to drive the adoption of green energy solutions. In 2022, Charles River was recognized by the U.S. Environmental Protection Agency's Green Power Partnership as a leader in green electricity use. Last year, the company joined the Renewable Thermal Collaborative, a global coalition of companies, institutions, and governments committed to scaling up renewable energy for heating and cooling. Charles River also sponsored Energize, a program powered by Schneider Electric to increase access to renewable energy for pharmaceutical supply chains.
• Invested $13.5 million in sustainability-focused projects through the Charles River Sustainability Capital Fund. From 2020-2023, Charles River has funded over 100 projects globally that reduce its environmental footprint, including energy conservation and GHG reduction efforts.
• Reduced GHG Emissions from its facilities significantly. As of year-end 2023, Charles River had achieved a 37 percent reduction in GHG emissions from its facilities (Scope 1 and 2 emissions). With the increase to 100 percent renewable electricity in 2024, Charles River is targeting a 45 percent reduction by year-end 2024, making progress towards its goal of a 50 percent reduction by 2030.
