Chemists Celebrate Earth Week (CCEW)

Chemists Celebrate Earth Week

CCEW encourages ACS members and science enthusiasts to build awareness of chemistry at the local level. ACS local sections, schools, businesses, and individuals are invited to organize or participate in events in their communities with a common goal: communicate the positive role that chemistry plays in the world.

CCEW 2019 was celebrated April 21-27, 2019 with the theme, "Take Note: The Chemistry of Paper." Thank you to all those who participated!

CCEW 2020 will be celebrated April 19-25, 2020 with the theme, "Protecting Our Planet Through Chemistry." The CCEW 2020 edition of Celebrating Chemistry and other online resources will be available February 1, 2020.
