Chemists Celebrate Earth Week

Theme: Protecting Our Planet through Chemistry


For years, chemists have been promoting a better world through recyclable plastics, cleaner-burning fuels, phosphate-free detergents, environmental monitoring, and green chemistry initiatives. To promote the positive role that chemistry plays in the world, ACS established the Chemists Celebrate Earth Week (CCEW) public awareness campaign. During CCEW, ACS members and chemistry enthusiasts celebrate by coordinating events and communicating the importance of chemistry. Read more about CCEW.

CCEW 2020 was celebrated virtually April 19–25 with the theme, “Protecting Our Planet through Chemistry.” Check out media from the various virtual events via the CCEW 2020 Album on Facebook and submit your event information and photos. CCEW 2021 will be celebrated April 18–24 with the theme, “Reducing Our Footprint with Chemistry.”
