Delhi green initiatives and public transport

Launch of 'Ek Ped Maa Ke Naam' campaign in Delhi targeting 70 lakh saplings.
Initiative to plant 1 crore saplings across 6,300 hectares of the Delhi Ridge over four years.
Strategy to replace invasive species (e.g., babul) with native species (peepal, banyan, neem, jamun) to restore biodiversity.
Plan includes development of 70+ ponds and preservation of archaeological structures within the Ridge.
5,000 hectares of the Ridge notified as reserved forests in the past year to provide legal protection.
Induction of 300 new electric buses (195 nine-metre and 105 twelve-metre) into the public transport fleet.
Inauguration of three new bus depots at Narela, Rithala, and Kohat Enclave.

Delhi government's AI-powered Dust Portal 2.0

The Delhi government has launched 'Dust Portal 2.0', an AI-powered platform designed to monitor air pollution.
The portal specifically targets construction and demolition sites that measure 500 square yards or more.
The initiative aims to transition from traditional regulatory enforcement to a technology-driven administrative approach for managing dust pollution.

Delhi e-bus expansion under PM e-Drive Scheme

Delhi to add 2,800 air-conditioned low-floor electric buses to its public transport fleet by August 2028 under Phase I of the PM e-Drive Scheme.
Projected total fleet strength for Delhi by 2028-29 is 14,000 buses.
Fleet composition: 1,400 buses of 12-metre length and 1,400 buses of 9-metre length.
Strategic deployment: 9-metre buses are intended for narrow roads and rural areas to enhance last-mile connectivity.
Financial assistance under PM e-Drive: ₹35 lakh per 12-metre bus and ₹25 lakh per 9-metre bus.
Procurement mechanism: Nationwide competitive bidding process utilized to ensure cost-efficiency and best-in-class rates.
Primary objectives: Reduction of vehicular emissions to improve air quality and modernization of urban public transport infrastructure.

Drone surveillance for stubble burning

The Commission for Air Quality Management (CAQM) has directed Delhi, Haryana, Uttar Pradesh, Rajasthan, and Punjab to implement drone surveillance for monitoring stubble burning.
Drones (UAVs) provide rapid deployment, high-resolution real-time imaging, and flexible flight patterns.
Drone technology complements existing satellite imagery and ground-level inspections.
Capabilities include detecting active fire locations, identifying smoke plumes, mapping affected fields, and generating time-stamped evidence for enforcement.
Monitoring efforts are to focus on paddy cultivation areas, specifically targeting identified hotspots and fire-prone locations.

Delhi transport infrastructure and bus services

Delhi government launched 56 ladies-special buses, with 26 specifically serving Delhi University routes.
Ladies-special buses operate during peak morning and evening hours, staffed with female personnel including police and Home Guards.
200 new electric buses added to the Delhi Transport Corporation (DTC) fleet.
Total DTC fleet size reached 6,800, with the electric bus component exceeding 5,000 units.
New electric fleet consists of 88 12-metre buses and 112 nine-metre DEVi buses.
Launch of inter-state electric bus service between Delhi and Karnal, operating 10 daily trips in each direction.
Inauguration of a new electric vehicle (EV) charging station at Rajghat Depot-1.

CAQM and ISRO collaboration for stubble fire monitoring

The Commission for Air Quality Management (CAQM) is collaborating with ISRO to improve the monitoring of stubble fires in Punjab and Haryana.
Current satellite-based fire counts are considered insufficient for accurate assessment due to limitations in sensor resolution and inability to measure straw quantity, moisture, and combustion efficiency.
Data indicates a shift in peak farm fire activity from 1:30 p.m. (2020) to 5:00 p.m. (2024), likely to evade detection by polar-orbiting satellites.
Farm fires contribute up to 15% of total particulate matter pollution over winter, but this can spike to 44% during specific weeks in October and November.
Pollution peaks occur when monsoon withdrawal stalls westerly winds, preventing the dispersal of pollutants from vehicles, industry, and agriculture.
CAQM is seeking a new 'ground truthing' protocol from ISRO to move beyond simple fire counts for better estimation of pollution impact.
