1 Million Women, founded by Natalie Isaacs in 2009, has become the largest women’s environmental organization in Australia, with nearly 83,000 women cutting over 100,000 tonnes of carbon pollution through small daily acts and coordinated mobilizations. When they reach their target of a million women as members and over a million tonnes of CO2 pollution saved, they will have generated carbon reductions equivalent to taking 240,000 cars off the road for a year.
