We are deeply saddened to share the news of the passing of Dr. Satyendra Kumar Purkayastha, who passed away on 20 March 2025. He was a respected expert and a lifelong supporter of the Montreal Protocol and its goals.
 
Dr. Purkayastha spent more than 26 years helping Bangladesh carry out its work under the Montreal Protocol. Thanks to his leadership and technical skills, the country made strong progress in phasing out ozone-depleting substances and meeting its international commitments. His efforts made a real difference in protecting the ozone layer.
 
As Project Manager for several phases of the Institutional Strengthening Projects at the Department of Environment, he played an important role in projects like the RMP, NOPP, HPMP, and helped with Bangladesh's ratification and early implementation of the Kigali Amendment.
 
Dr. Purkayastha was known for his calm and humble nature. He had a Ph.D. in Pharmaceutical Chemistry, published research on cancer treatments, and always approached his work with scientific care and dedication. Beyond his many achievements, he guided and encouraged many young professionals who will carry on his legacy.
 
His passing is a great loss to the ozone family. We remember him with gratitude and respect for his lifetime of service to the environment.
 
Our thoughts are with his family, friends, and colleagues.
