The TPP on the environment

This article details a WikiLeaks document that reveals a draft chapter of the TPP agreement on the environment. As we've seen on other 'free trade' [sic] agreements, it makes environmental standards voluntary, with no enforcement or penalty for violations. If the final chapter of the agreement stays this way then according to the Sierra Club the Obama admin's environmental trade record will be "worse than George W. Bush's." Wow, that is bad. The US even objects to the climate change section.
