Experience Thundays

Imagine a world where, one day each week, the sunrise brings cleaner air and happy sounds of Nature. For a whole 24 hours you take a complete break from the fast pace of modern life; and communities unite in care for the Earth. A complete human-slow down; and a taste of greener tomorrows. These days are Thundays.

The Thundays vision

A weekly 24hour global pause, reducing greenhouse gas emissions by 14.9%, and connecting millions of people with shared action and a shared vision.  This dramatic human slowdown sends an extraordinary, powerful message to world leaders: Thundays demand a new way of living to preserve humanity in harmony with Nature.

How Thundays work

Every Sunday is a day of undoing: switch off from modern life and do your best for Nature. Rest, have fun; feel happy and hopeful.  Unite with others around the world quietening the streets, silencing cyberspace and seeing only birds in the sky. Practice new tomorrows and send huge global message for positive change.
