NT Verdict
Misleading
The Claim Being Checked
“Air pollution in Delhi has reduced by 30% over the last 5 years”
Said by
Delhi CM Rekha Gupta
Chief Minister, Delhi (BJP)
Where
Environment Day press conference, New Delhi
When
Mar 3, 2026
NT Verdict
Misleading
Accurate data used in a way that creates a false impression.
What NT Found
CPCB data shows Delhi PM2.5 declined from 103 μg/m³ (2019 avg) to 84 μg/m³ (2024 avg) — an 18.4% reduction, not 30%. The 30% figure uses 2016 as the baseline (119 μg/m³), not 2019. Selective choice of baseline inflates the reduction. Delhi at 84 μg/m³ is still 16× above the WHO safe limit of 5 μg/m³.
How We Verified This
Step 1 — Claim Flagged
Claim attributed to Delhi CM Rekha Gupta (Chief Minister, Delhi (BJP)) via Environment Day press conference, New Delhi on Mar 3, 2026. Assigned to fact-checker Amit Verma for verification.

Evidence 2
CPCB data: 2024 Delhi annual average PM2.5 = 84 μg/m³ = 18.4% reduction (5-yr)
Evidence 3
Government uses 2016 baseline (119 μg/m³) → gives 29.4% reduction
