Sh Alok Sahay, Secretary General, ISA at the Inaugural Session of CEM India 2026 International Conference & Exhibition on Continuous Emission Monitoring Systems, organised by iForest and International Labmate UK on 10th of March 2026.
CEMS is no longer optional it's the backbone of industrial environmental compliance. From the Clean Air Act era in the 1970s US to India's 2014 CPCB mandate, we've come a long way.
Today, 17 industries including iron & steel must run 24/7 real-time emission monitoring tracking PM, SO₂, NOx, CO, CO₂, NH₃, & O₂.
Take a look at this chart showing the composition of atmospheric air something we all learnt in school:
1. Nitrogen -78%
2. Oxygen-21%
3. Other gases (mostly Argon)-0.96%
4. Carbon Dioxide - just *0.04%*
Now here's the sobering part: *40% of that 0.04% CO₂ is manmade.* If this minuscule fraction is already driving climate change across the globe, imagine what happens if it grows unchecked. This is precisely why continuous emission monitoring matters.
Two areas the CEM equipment industry must prioritize going forward:
• Aerosols, Dust & Particulate Matter (AQI)
• Real-time alarm systems
Congratulations to iForest for this important biannual event bringing global equipment manufacturers and Indian industry together.
