What people say…

“Chetan ran a workshop on communication and media engagement on the margins of the Africa Clean Air 2026. Participants appreciated the hands-on approach and the real-life examples that provided practical ideas for applying learnings from the workshop in day-to-day work.”
Dr Pallavi PantHealth Effects Institute
“Chetan worked with us on the India Clean Air Summit 2024, providing guidance on programming and communication strategies. We received good reviews for the programming, and I was quite happy with the stories that came out. I highly recommend Chetan’s services to others planning similar conferences or needing support for communications strategies.”
R SubramanianHead, Air Quality, Centre for Study of Science, Technology and Policy
“Chetan and I worked together for nearly three decades at NDTV, when it was among the world’s best news networks. Chetan was a key component of our editorial coverage. His instincts for spotting a developing story, acting on that quickly with reporters, and then getting that story on air, after all safety checks, ensured NDTV was at the top of its game.”
Suparna SinghCEO and Co-Founder, Frammer AI; former President and CEO, NDTV Group
“Chetan Bhattacharji is an experienced climate reporter… In his brief time writing for Health Policy Watch, he has already impressed us with his knowledge of the climate science, air pollution and policies in India, as well as his fluent writing style.”
Elaine Ruth FletcherEditor-in-chief, Health Policy Watch
