Let there be no doubt about this: business activity generates economic opportunities and services that are vital to the enjoyment of human rights.

Bhopal brought new attention to the negative impact that business can have on human rights, and led to growing calls for justice and accountability...Here today in Geneva are the representatives of companies that are taking action to implement the Guiding Principles...I would like to see far more businesses engaged in this work...
