You might call it “The Firewall Strategy”: a plan to break the gridlock in climate negotiations by excluding polluters. The tobacco treaty contains articles prohibiting sales to minors, banning tobacco advertising, and requiring that packaging contain warning labels. But it also locks big tobacco out of the room when it comes to drafting and influencing health policy. To avoid these conflicts, the guidelines prohibit tobacco industry employees from serving as delegates, ban policymakers from accepting gifts from tobacco companies, and insist that interactions between policymakers and the tobacco industry be transparent to the public. Supporters of a firewall strategy also acknowledge there are differences between big tobacco and big oil—specifically, the fact that big oil is even bigger than big tobacco ever was.
