HallowGreen™ Challenge

Our 6th annual HallowGreen™ Challenge is designed to help educate the public on different things they can do during the month of October to make lifestyle s-witches for the planet. 

With your help, we can engage local and global communities to participate in climate action.

Will you help us scare away climate anxiety?

2021 has been a spooky year for Planet Earth!
