If you’re celebrating World Carfree Day today, pat yourself on the back once for thinking outside the car — and a second time for participating in Pollution Prevention Week!

I discovered today that Sept. 20-26 marks Pollution Prevention Week, which is how the U.S. Environmental Protection Agency is celebration the 20th anniversary of the Pollution Prevention Act (via The Green Life). If I’d known about the week-long eco-festivities earlier, I would have given you more notice about a green beauty session the EPA is hosting today — but I hope some of you will still be register to participate!

What: Understanding the Environmental and Health Impacts of Personal Care Products
When: Wed., Sept. 22, 1 p.m. – 2:30 p.m. ET
How: Register online to participate.

The name of the EPA session itself — which basically reveals that the EPA agrees some legal “beauty” products simply aren’t so good for us or the environment even though the agency doesn’t yet have the power to keep those products from being sold on drugstore shelves — is quite bold. According to the EPA’s description, the session will show you how to pick better beauty products — with an emphasis on nail polish or hair dyes — and include a tutorial on how to use the Environmental Working Group’s Skin Deep Cosmetic Safety Database, a resource I recommend all the time!

The EPA will also host a session on Greening Your Business on  Thurs., Sept. 23 from 1 p.m. to 2:30 p.m. ET. Find out more about that event and other Pollution Prevention Week tips, activities, and news at the EPA’s website.
