For decades, fossil fuel companies have fought action on climate change. They've done so directly – by challenging legislation that would help reign in emissions. But they've also done it indirectly, by funding organizations who lobby congress, launching fake grassroots campaigns, and perhaps most importantly, through advertising. These ads, according to Martin Watters at the nonprofit firm ClientEarth, are greenwashing. They help sow doubt about the fossil fuel industry's role in warming the planet. This week, we take a look at those ads and examine how they stymy the conversation on climate. We also talk to some people working hard to get rid of these types of ads. They aren't going after the fossil fuel companies directly. Instead, they're targeting the people who help fossil fuel companies greenwash their image: the ad creators. 

Guests: Martin Watters, Duncan Meisel, Adam Lerman
