The use of green crackers aims to mitigate air pollution during Diwali celebrations in Delhi-NCR, where air quality typically deteriorates due to stubble burning, vehicular emissions, and unfavourable weather conditions. However, green crackers still release particulate matter and smoke, which can exacerbate respiratory issues for vulnerable groups such as children, the elderly, and individuals with asthma or COPD. Strict enforcement of certification rules and limited use are crucial to minimising health risks and environmental impact.
