Jeff Sachs says "polluters must pay":
Polluters Must Pay: When BP and its drilling partners caused the Deepwater Horizon oil spill in the Gulf of Mexico in 2010, the United States government demanded that BP finance the cleanup, compensate those who suffered damages, and pay criminal penalties for the violations that led to the disaster. BP has already committed more than $20 billion in remediation and penalties. Based on a settlement last week, BP will now pay the largest criminal penalty in US history – $4.5 billion.
The same standards for environmental cleanup need to be applied to global companies operating in poorer countries, where their power has typically been so great relative to that of governments that many act with impunity, wreaking havoc on the environment with little or no accountability. As we enter a new era of sustainable development, impunity must turn to responsibility. Polluters must pay, whether in rich or poor countries. Major companies need to accept responsibility for their actions. ...I can't see the companies doing this voluntarily.
