Environmental standards not enforceable
The TPP was supposed to include enforceable commitments by governments to at least seven international environment agreements. But analysis by environmental law experts shows the text mentions only four, and only one - on trade in endangered species - has clearly enforceable commitments.
There is no mention of climate change. Global corporations could use ISDS to sue governments for taking action against climate change.
