Gilead Sciences Commits to Reducing our Global Greenhouse Gas Emissions by 25 Percent by 2025

Foster City, Calif. – April 4, 2019 – Gilead Sciences, Inc. announced that it has joined more than 500 of the world’s leading companies in committing to reduce greenhouse gas (GHG) emissions. Climate change, intensified by GHG emissions, poses a major threat to the health of populations and environments worldwide.

“Science is at the core of Gilead’s business, and the science of climate change is clear,” said Joydeep Ganguly, Senior Vice President, Corporate Operations. “At Gilead, we recognize the urgency to mitigate the threat of climate change and are committed to doing our part to transition to a low-carbon future. We believe that protecting the environment is integral to our mission, which is why we continuously strive to improve our environmental practices through conservation and pollution-prevention principles.”

The impact of climate change on underserved and at-risk populations has enormous implications for global health. These include increased transmission of serious diseases, compounding health risks for the young and elderly, and greater danger for those already immunocompromised. Gilead stands by our patients, at-risk populations and the environment through an ambitious GHG strategy.

In line with the Paris Agreement’s central aim of keeping the global temperature rise below 2 degrees Celsius this century, we have committed to reducing our global scope 1 and 2 greenhouse gas emissions by 25 percent by 2025, compared with a 2016 baseline. To meet this goal, we have developed a multi-year plan that includes procuring renewable energy for locations where we will have the greatest impact and applying energy efficient technologies and measures to improve the performance of our facilities.

We are also committed to external annual reporting of our scope 1 and 2 emissions and the progress we are making ahead of 2025. Our scope 1 and 2 emissions are calculated in accordance with the World Resources Institute (WRI)/World Business Council for Sustainable Development (WBCSD) Greenhouse Gas Protocol Corporate Standard and are verified by a certified assurance provider using the International Organization for Standardization (ISO) 14064-3 standard for greenhouse gas assertions. Our reporting boundary includes all sites for which Gilead maintains operational control during the reporting period.
