Are you a backyard eco-warrior in Munich, Germany? Or saving the world one recycled bottle at a time in Sao Paulo, Brazil? Wherever you are in the world, CNN wants to know what you are doing to reduce your carbon footprint.
No idea is too small! We want to see what you are doing to make our world a greener place to live. It's easy, just grab your mobile phone or camcorder and film what you are doing for a couple of minutes and upload it to iReport.
So, no matter where you are in the world, send in a video of your green ideas in action, or other ideas you've seen at work. Your submissions may be featured each month during our 30-minute show exploring the cities making strides in reducing their carbon footprint, ahead of the Rio+20 Earth Summit in July.
