Environment Minister Manjinder Singh Sirsa reviews First-of-its-Kind Pilot Project to Deploy 30 Emission Retrofitting Devices in Delhi Delhi Launches First-of-its-Kind Emission Retrofitting Pilot for Heavy Vehicles: Manjinder Singh Sirsa

Sirsa announces a pilot to install 30 catalytic converter-based retrofitting devices in Delhi’s heavy vehicles, aiming to cut harmful emissions by over 70%. DPCC to lead the project.

New Delhi– In a landmark move to combat vehicular pollution, the Delhi Government is evaluating viability of a pilot project to  deploy 30 advanced catalytic converter-based retrofitting devices in heavy commercial vehicles. The initiative, led by the Delhi Pollution Control Committee (DPCC), is the first-of-its-kind in the country and reflects the Government’s strong commitment to harnessing technology for sustainable environmental solutions.

Minister for Environment, Forest & Wildlife,  Manjinder Singh Sirsa, informed that the catalytic converter retrofitting devices will be installed after the exhaust of heavy vehicles — a solution that has demonstrated the capability to reduce particulate matter and other harmful emissions by more than 70% in BS-III and BS-IV vehicles.

“Delhi is taking a decisive leap towards tech-driven pollution control. This is not only a first-of-its-kind effort in India but also a solution that can be replicated in other cities and sectors where fossil fuel engines are a major source of pollution. I am encouraged by the fact that more and more companies and innovators are approaching us with product demonstrations. This shows that our city is now seen as a leader in supporting and implementing innovative environmental solutions,”  Sirsa said.

The decision follows the context of CAQM’s directions on restricting older, higher-polluting vehicles from entering Delhi. The Delhi Government, while fulfilling all legal commitments to follow law and implementing these measures, is equally focused on providing innovative, science-backed alternatives that protect livelihoods while reducing pollution.

 Minister informed that these retrofitting devices have demonstrated the capability to reduce particulate matter and other harmful emissions — PM, CO, HC, and NOx — by more than 70% in BS-III and BS-IV vehicles. They have been rigorously tested for durability, low backpressure, regeneration capability, and over 9,000 km of field use.

“This pilot is a trial and a statement of our vision — to deploy permanent, innovative solutions that clean Delhi’s air while keeping essential transport running,” Sirsa added.

The decision came after deliberations on how such technology could play a vital role in addressing one of Delhi’s biggest environmental challenges — pollution from heavy vehicles. If successful, the pilot will pave the way for large-scale adoption across Delhi and possibly in other parts of the country.

The  minister informed that DPCC will serve as the single point of contact for the project, coordinating with departments such as PWD, MCD, DJB, and Health, and providing a list of government and autonomous body vehicles meeting BS-IV or earlier norms. Testing will be undertaken in collaboration with IIT Delhi or ICAT.

“Our goal is not just to comply with environmental directives, but to lead the way in building a cleaner, healthier, and more sustainable Delhi. This pilot shows that with the right technology, determination, and governance, we can solve even the toughest environmental challenges while protecting livelihoods.”
