CCEW Themes

The American Chemical Society began celebrating Earth Day in 2003. Since 2003, the Committee on Community Activities has chosen an annual theme to give direction and variety to that year’s celebration, but archived materials can be of use during any time of year. In 2018, the program becomes Chemists Celebrate Earth Week (CCEW) and will be celebrated during the week of April 22.
