In Australia, women are building a movement to tackle climate change. 1 Million Women has a simple goal with a big impact: get one million women to pledge to take small steps in their daily lives to save energy, reduce waste, cut pollution and lead change. Thus far, they’ve signed up more than 100,000 women to their campaign. Together, they’ve committed to cut more than 100,000 tons of carbon emissions.

In this week’s podcast, we interview 1 Million Women founder, Natalie Isaacs.
