Delhi Fails to Meet PM10 Target; Noida Shows Improvement

Delhi misses air quality targets, while Noida shows progress in PM10 levels.

Background Context

The issue of air pollution in Delhi and the NCR region has a long history, dating back to the rapid industrialization and urbanization that began in the late 20th century. The increasing number of vehicles, construction activities, and industrial emissions contributed significantly to the deteriorating air quality. Early attempts to address this involved the introduction of compressed natural gas (CNG) for public transport in the early 2000s, following a Supreme Court directive. However, these measures proved insufficient to tackle the growing problem. The establishment of bodies like the Environment Pollution (Prevention and Control) Authority (EPCA) and later the Commission for Air Quality Management (CAQM) marked significant steps towards a more structured approach to air quality management. The evolution of policies and action plans reflects a growing understanding of the complex factors contributing to air pollution and the need for multi-faceted solutions.

Delhi has failed to meet the targets set under the National Clean Air Programme (NCAP) for PM10 levels, lagging behind Noida in achieving air quality improvements. According to data released today, Delhi's air quality remains a significant concern, with PM10 levels exceeding the permissible limits. In contrast, Noida has shown progress in reducing PM10 concentrations, although it still faces challenges. The Commission for Air Quality Management (CAQM) has flagged deficiencies in the implementation of the Graded Response Action Plan (GRAP) measures in the National Capital Region (NCR).

Latest Developments

In recent years, there has been increased focus on addressing stubble burning in neighboring states, a major contributor to Delhi's winter air pollution. Initiatives like providing subsidies for farmers to adopt alternative methods of crop residue management have been implemented. The use of technology, such as air quality forecasting models and real-time monitoring systems, has also become more prevalent. The CAQM has been actively involved in coordinating efforts across different states in the NCR region. Looking ahead, there is a growing emphasis on promoting electric vehicles, expanding public transportation, and implementing stricter emission norms for industries. The success of these measures will depend on effective enforcement and sustained commitment from all stakeholders.
