The Green Rating Project (GRP) was started by the Centre for Science and Environment (CSE) as a civil society initiative to develop an alternative form of governance to control industrial pollution in India. Using a carrot and stick approach, GRP rated companies within sectors to motivate improvements. It involved industry, civil society, and government experts to ensure credibility and motivate large companies. The ratings were made public to encourage more participation and further industry's environmental improvements. GRP aimed to address drawbacks like a lack of transparency and centralized environmental performance data for industries in India.
