City vision — Satellite vs Environmental Impact Proxy

Left: Real Chennai satellite imagery (ESRI World Imagery). Right: a scientifically bounded environmental impact proxy based on commute CO₂, fuel type, tailpipe status, route corridors, and local-pollutant co-emission risk. It is a relative visual model, not measured AQI or an actual smog prediction.

ZeroLowModerateHighCritical

📡 Satellite imagery: ESRI World Imagery (free, public). Environmental impact proxy: qualitative aerosol-style visualization using trip activity, fuel type, PUC status, and route/corridor intensity. One commute cannot visibly change city smog; this is not measured AQI or a forecast.

★ Key benchmarks: petrol sedan fleet avg 120.6 g/km (ICCT/MoRTH 2021); Honda City HEV ~70 g/km (ICCT LCA 2025). EV values use city/state grid intensity from CEA (current Chennai/Tamil Nadu setting: 0.716 kg CO₂/kWh). CNG via IPCC 2006 × ARAI mileage. 1 tree ≈ 21 kg CO₂/yr (IPCC AR6).

PUCNational Government Services Portal. PUC certificates confirm whether vehicle emissions meet required norms; the calculator uses the PUC value as a maintenance correction, not as a direct CO₂ measurement. Source

Gap fixed: grid electricity now cites CEA's CO₂ Baseline Database instead of a state utility-only note, so EV and rail factors have an India power-sector source.

Gap fixed: vehicle comparisons cite ICCT's India life-cycle work and IPCC AR6 transport context instead of relying only on raw table factors.

Gap fixed: PUC is treated as a maintenance and tailpipe-pollutant proxy. It is not used as a direct CO₂ instrument.

Remaining approximation: city fleet mix, live congestion emissions, real AQI chemistry, and satellite-impact visuals are modeled estimates. Admin factors should be recalibrated when verified city fleet or remote-sensing data is available.
