Absence of guidelines on “acceptable inequality” in exposure to toxic air is no longer just an oversight — it is active concealment leading to grave injustice. 1/6 Supreme Court has repeatedly held (M.C. Mehta 1986, Subhash Kumar 1991, Vellore Citizens 1996, MK Ranjitsinh 2024) that • Right to pollution-free environment is fundamental under Art 21 • Precautionary principle & equality (Art 14) are binding • Disproportionate burden on any community is unconstitutional. Yet CPCB has never defined what level of differential exposure is permissible. 2/6 MoHFW/NCDC itself admits (Health Advisory Oct 2023): “Long-term exposure to even lower levels of air pollution can cause lung cancer, respiratory & cardiovascular diseases and premature deaths.” → There is NO SAFE THRESHOLD. 3/6 Despite this knowledge, CPCB refuses to publish: • Maximum permissible gap in cumulative exposure (Area Under Curve of concentration × time) for PM2.5, NO₂, O₃, benzene, BaP etc. • Acceptable disparity ratios between “clean” and “poisoned” zones → This deliberate silence creates legal ambiguity and forces citizens into endless litigation. 4/6 Result? • Poor & marginalised communities breathe 10–15× higher pollution year after year • Polluters exploit the vacuum — no benchmark = no violation • Courts are flooded with PILs because statutory bodies abdicate their duty to quantify & enforce equality in the most basic right: breathing. 5/6 Air (Prevention & Control of Pollution) Act 1981 was enacted to prevent exactly this kind of disproportionate poisoning of vulnerable populations. By not issuing differential-exposure thresholds, CPCB is defeating the very object of the Act and encouraging systemic environmental injustice. 6/6 We demand immediate release of scientific guidelines on maximum permissible inequality in cumulative exposure to criteria pollutants & toxics. Hiding behind “no data” is no longer acceptable when lives are being lost. #EnvironmentalInjustice #RightToCleanAir #Article21 #PrecautionaryPrinciple @CPCB_OFFICIAL @MoEFCC @MoHFW_INDIA @CAQM_NCR @CSEINDIA @parisar_pune @LungCareIndia @warriormomsin @HelpDelhiBreathe @cleanairmoms @PunePMC @MPCBNagpur @IndiaSpend @teriin @greenpeaceindia @ChintanIndia @Waatavaran @RespirerLiving @PranaAir #PuneAirPollution #AirQualityCrisis #EnvironmentalRacism #CleanAirForAll #PolluterPays #NoSafeThreshold #CumulativeExposure #PM25Kills #Article14Violation #Article21Violation #NCAPFail #SwachhHawa #BreatheIndia #StopEnvironmentalInjustice #PollutionInequality #DelhiSmog #PuneChokes #AQIAlert #HealthEmergency #ClimateJustice #EndPollutionApartheid
