The Delhi Government is exploring the use of “smog-eating” photocatalytic coatings on its roads and public spaces. This strategic move, announced by Environment Minister Manjinder Singh Sirsa, aims to use science-backed tools to deliver cleaner air for citizens.
The Environment Department has been tasked with conducting a focused study on these coatings, which are designed to reduce harmful pollutants like NO2 and hydrocarbons.
The minister emphasized a commitment to a 24x7, 365-day environmental action plan, moving away from seasonal interventions. “Delhi will evaluate and adopt the best of proven photocatalytic technologies, prioritising safety and sustainability to deliver cleaner air,” he said.
He underscored that the fight against pollution is personal for every resident.
According to Minister, the department will partner with a reputed scientific institution within 30 days to begin field trials on actual city streets. The study, which will be transparent with monthly progress reports, is expected to be completed within six months of a Memorandum of Understanding (MoU).
Its focus will be on safety, sustainability, and cost-effectiveness. The plan is to identify credible suppliers for a potential citywide rollout if the results are promising.
If the technology proves effective and affordable, the Government will fast-track a Cabinet proposal for its rapid deployment. Priority locations will include busy corridors, markets, and other public areas to achieve visible and immediate air quality gains. This initiative is part of a broader strategy championed by the Government to use innovation to address pollution. The “Innovators’ Challenge,” a platform encouraging solutions from students, startups, and experts, has been a key driver.
The minister urged innovators to bring their best ideas forward, assuring that the Government would test, fund, and scale up what works to make a tangible difference in the lives of every family. “From day one, this administration has backed innovation to find real, on-ground answers to pollution — backed by science, tested on our streets, and scaled for people,” he said.
He noted that the challenge has drawn students, startups and experts in large numbers, with the Environment Department short-listing ideas for rapid pilots and evaluation.
“Bring your best ideas—Delhi will test them, fund what works, and take it citywide so every family can breathe easier,” he added.
