Understanding CPCB IV+ Norms: What They Mean for Diesel Generator Users in India What is CPCB IV+? CPCB IV+ is the latest emission compliance standard issued by the Central Pollution Control Board of India. It governs how much pollution a diesel generator (up to 800kW) is allowed to emit. This new standard came into mandatory effect on July 1, 2023, replacing the earlier CPCB II norms. It marks a significant shift toward cleaner and more environmentally responsible power generation. Why Was CPCB IV+ Introduced? India’s growing industrial and infrastructure sectors have driven the demand for diesel generators—but also increased harmful emissions. CPCB IV+ aims to: Reduce air pollutants such as particulate matter (PM), nitrogen oxides (NOx), and hydrocarbons. Promote cleaner engine technologies across the power generation sector. Align India’s emission norms with global standards like the EU Stage V. Support national sustainability and clean air goals. What’s New in CPCB IV+ Compared to CPCB II? Feature CPCB II CPCB IV+ Emission Limits Moderate Much stricter Engine Tech Basic Advanced (CRDI, DPF, SCR) Compliance Cost Lower Higher, but eco-friendly Fuel Compatibility Regular diesel Higher efficiency expected What This Means for You All new diesel generators sold after July 1, 2023, must comply with CPCB IV+ norms. If you’re currently using an older CPCB II model, you can continue to use it, but upgrades will be necessary for future compliance.
