Unreliable air and noise data, real-time deception, Pg6

Key Highlights:

• Delhi's Real-Time Air Pollution Network and Lucknow's National Ambient Noise Monitoring Network face governance questions due to unreliable data.
• Air quality data in Delhi is often reported as "moderate" despite citizens experiencing toxic smog.
• In 2017, noise pollution levels in seven Indian cities exceeded limits set by the CPCB.
• Flaws in monitoring systems and lax enforcement undermine India's global environmental commitments.
• Misleading environmental data suppresses citizens' rights to health and life.
• The Air Quality Life Index report indicates that Delhi's average life expectancy could rise by 8.2 years if air quality met WHO standards.

Detailed Insights:

• The CAG report revealed flaws in Delhi's air quality monitoring network, including sensors placed in unrepresentative locations.
• Weak monitoring systems compromise action plans related to stubble burning, vehicular restrictions, and industrial emissions.
• India's reliance on the outdated Noise Pollution (Regulation and Control) Rules, 2000 is inadequate compared to WHO guidelines.
• Misleading data on air and noise pollution delays judicial intervention and weakens fundamental rights.
• The Supreme Court has acknowledged noise pollution as a constitutional and public health issue, transferring pleas to the NGT.
• Lack of independent scientific scrutiny and third-party audits erodes public trust in official environmental data.
• Exposure to pollutants like nitrogen dioxide (NO2) and PM2.5 weakens lungs and accelerates myopia, impacting vulnerable populations.
• The article suggests installing sensors according to standards, keeping raw data open, enabling third-party audits, and creating citizen oversight.

Key Concepts Involved:

• Air Quality Index (AQI): A measure of air quality based on pollutants like ozone, PM2.5, PM10, carbon monoxide, sulfur dioxide, and nitrogen dioxide.
• Central Pollution Control Board (CPCB): A statutory organisation under the MoEFCC responsible for setting and enforcing environmental standards.
• National Green Tribunal (NGT): A specialized judicial body that handles environmental disputes.
