September 23, 2025 | CPCB Issues OCEMS Directive on Real-Time Emission Data
On 23 Sept 2025, CPCB directed industries to register on the new OCEMS portal for emission and data reporting. Learn what this means for businesses.
On 23 September 2025, the Central Pollution Control Board (CPCB) issued a directive under the Water Act (1974) and Air Act (1981), addressed to all State Pollution Control Boards (SPCBs) and Pollution Control Committees (PCCs). The order requires industries across India, particularly those in 17 highly polluting sectors and NCR-Delhi units, to register and connect their continuous monitoring systems to the new OCEMS/ODAMS portal.
Companies must submit metadata such as location coordinates, sector categorisation, analyser details, and station information, while enabling direct real-time data transfer to CPCB servers. The system also mandates PTZ camera integration, geotagging of stations, revised calibration protocols, and stronger alert systems.
The circular sets immediate deadlines:
NCR/Delhi industries must register by 15 October 2025
Other industries by 15 November 2025.
For businesses, this translates into immediate EHS planning, software integration, and hardware verification to avoid regulatory and reputational risks.
Stakes for Businesses:
For businesses, this directive is not just another compliance checkbox. It fundamentally changes the way their environmental performance is monitored, reported, and judged:
Reputational exposure: Since compliance data will be public, investors, buyers, and even customers will gain visibility into how responsible a business really is. This can directly influence supply chain decisions and access to capital.
Cost implications: Stricter oversight may require industries to upgrade effluent treatment plants, emission monitoring systems, and data reporting tools, increasing operational expenses.
ESG alignment: For listed companies and exporters, this directive complements global sustainability disclosure frameworks, making it harder to “greenwash.”
Competitive advantage: Early adopters of real-time monitoring technology will have an edge in both compliance and brand positioning, as regulators and buyers increasingly favour data-backed credibility.
What to Watch / Directive’s Implications:
Tight timelines: NCR units have less than a month to integrate, requiring urgent IT and climate tech integration and capital allocation.
Operational disruption: Non-compliance can lead to shutdown orders, penalties, or loss of permits.
Data transparency: With analytics and dashboards accessible to regulators, any deviations are instantly visible, leaving less room for corrective delays.
Multi-state challenge: Companies with facilities across India must coordinate compliance across SPCBs that have varying digital maturity.
For businesses, the real risk is not just regulatory fines but loss of credibility in ESG audits and investor due diligence if data gaps or non-compliance are flagged.
Business next steps checklist:
Register on the CPCB OCEMS/ODAMS portal and confirm industry login credentials.
Map all monitoring stations with GPS coordinates and maintain an updated list of analyser models and serial numbers.
Validate CEMS against the revised calibration protocol; schedule certification or performance trials with NABL/EPA-recognized labs.
Budget for PTZ camera feed integration and ensure secure direct telemetry to CPCB servers (eliminating third-party TPDS dependency).
Update procurement and supplier contracts to include compliance clauses and documentary evidence requirements for telemetry. Here, automated compliance platforms like The Sustainability Cloud streamline integration of monitoring stations, calibration logs, and direct data transfers, reducing manual gaps keeping business audit ready.
With CPCB deadlines approaching, businesses now have an opportunity to turn compliance into a competitive advantage. Early adopters of real-time monitoring platforms not only reduce regulatory risk but also strengthen ESG credibility and investor confidence.
