The Delhi-based Centre for Science and Environment (CSE) sets a good example of how to use the power of empirical evidence to change both minds and laws.
Launched in 1980 by science journalist Anil Agarwal, the CSE has campaigned relentlessly around specific areas of Indian science and environmental policy, from air pollution to water resources.
They have had many successes — inspiring a switch from diesel fuel to compressed natural gas in the cities Delhi and Ahmedabad for instance.
More recently, the group has turned its attention to the levels of toxic pesticides in the soft drinks produced by industry giants Coca-Cola and PepsiCo.
What makes CSE different is a tactic that allows them to fight their battles on two fronts: they employ both journalists and scientists to add punch to their presentations — and back them with hard facts.
This approach has made them "one of the most influential organisations in the country", according to this Nature article.Link to full article in Nature
