The TPP would sabotage efforts to curb global heating in several ways.

This is a natural consequence of the way it was drawn up. For each area of business, the US government asked the companies in that area what they wanted. The fossil fuel companies asked for policies that will help them.

Fundamentally, control of greenhouse gas emissions is good for the people, so it's what democracy will do if it works right. The TPP is a business-supremacy treaty with some secondary support for unregulated trade. What these treaties do is weaken democracy and give business more power.
