Kolkata’s Journey towards Better Air Quality: Challenges and Still a Long Way to Go
Introduction
In the past six years, Kolkata has been on an odyssey towards mitigating air pollution affecting millions of people. With policies changes, technology improvements and community participation, it has progressed moderately in a complex web of air pollution remediation.
Understanding Kolkata’s Air Pollution Challenges
Similar to many urban cities, Kolkata has many tributaries of air pollution: vehicular emissions, industrial emissions, dust from construction, and biomass burning. Collectively, these emissions have resulted in significant levels of PM2.5 (fine particles) and PM10 (inhalable coarse). The high levels of these air pollutants pose various health risks.
Key Strategies Implemented
Transition to Cleaner Transportation
- Electric and CNG Vehicles: The city introduced electric buses and CNG-powered vehicles to reduce emissions.
- Phasing Out Old Vehicles: Vehicles over 15 years old were banned to curb pollution.
- Promotion of Non-Motorized Transport: Initiatives to encourage cycling and walking were implemented.
Industrial Emission Controls
- Relocation of Polluting Industries: Industries with high emissions were moved outside city limits.
- Emission Standards Enforcement: Stricter regulations were applied to boilers, kilns, and other industrial equipment.
Dust and Construction Management
- Construction Site Regulations: Mandates for covering sites and using mist cannons were enforced.
- Road Dust Control: Regular water sprinkling and street cleaning were conducted to minimize dust.
Waste Management and Biomass Burning Reduction
- Solid Waste Segregation: Programs for separating waste at the source were initiated.
- Biomass Burning Surveillance: Drone monitoring and distribution of smokeless chulhas helped reduce open burning.
Urban Planning and Green Infrastructure
- Development of Flyovers and Underpasses: Infrastructure projects reduced traffic congestion and emissions.
- Protection of East Kolkata Wetlands: These wetlands acted as natural air purifiers and carbon sinks.
Monitoring and Data-Driven Approaches
The city expanded the air quality monitoring network to provide real-time data that can inform policy. The data-driven approach allowed for targeted interventions wherever pollution was higher.
Community Engagement and Public Awareness
Public campaigns were conducted to facilitate education and awareness of the importance of air quality, and behaviour changes such as limits on the use of individual vehicles and proper waste disposal.
Challenges and Areas for Improvement
With all this positive change, there remain challenges, such as the following:
• Surges in seasonal pollution levels: Pollution levels are still higher in winter given meteorological conditions.
• Funding distribution: It is important to ensure funds are allocated in priority areas.
• Ongoing enforcement: Ongoing regulation tracking and enforcement are needed to sustain improvements.
Conclusion
Kolkata’s diverse approach to improving air quality can be a signpost for other cities facing similar challenges. Combining policy, technology, and enhanced community efforts has progressed cleaner air and a healthier environment.
