Cool Block Program

How the Cool Block Program Works

  • A group of 5 to 8 households on your block or building meet 9 times over 4-½ months
  • Different team members host each topic in their home every two weeks with the support of a Topic Meeting Guide.
  • The meetings last 1.5 to 2-hours and focus on disaster resiliency, carbon reduction, water stewardship, neighborhood livability and empowering others. 
  • Between meetings, participants work with their household and block to take action.
  • The meetings follow a three-part rhythm. Review actions taken, share new actions to be taken, review the following topic.

That’s it! Everything you need to do is on the easy-to-use Cool Block website.

Note: If you wish to be a Cool Block leader, you will receive comprehensive training, tools and coaching support.
