Write a letter to a loved one in the future to call for political action on climate change now.

Because the future of our planet isn't written yet.

The climate crisis is affecting our lives already, and it’s only going to get worse for the next generation unless we take action now to get it under control – because the years will tick away before we know it.

That’s why we’re asking everyone to write to Letters to Tomorrow, as part of this year’s Great Big Green Week.

What are Letters to Tomorrow?

Letters to Tomorrow explain your hopes for future generations if our leaders step up to protect the environment – and your fears about what life could be like if we don’t slow down climate change.

Your letter could be to your friend, child or even your future self.

How does it work?

1. Write your letter

Using our simple online form, you can write a letter directly onto the site or upload an image of a handwritten letter. It only takes a few minutes to write a letter.

What happens next?

To make sure our leaders step up and take notice, we’ll send an individual letter every day to the Prime Minister and the Leader of the Opposition.

It’ll put climate change and nature on their to-do list every single day, reminding them that if they want to win our votes and be on the right side of history, they need to step up.
