As Delhi-NCR faces "severe" air quality levels, authorities have enforced Stage 4 of the Graded Response Action Plan (GRAP) to combat air pollution. This strict measure aims to curb emissions from older vehicles and reduce pollution in the national capital region.
For the unversed, the Graded Response Action Plan (GRAP) is a set of emergency measures implemented in phases based on air pollution severity in Delhi-NCR. Stage 4, the most stringent phase, occurs when the air quality index (AQI) reaches "severe" levels, imposing restrictions on various vehicle types to control emissions.
The goal of GRAP Stage 4 is to reduce emissions and halt the deterioration of air quality immediately. Older vehicles with less stringent emission standards contribute significantly to air pollution, making these measures essential for public health and environmental safety.
