Study Notes
Air Quality Impact
- Vehicular emissions are a major contributor to air pollution in India, accounting for 12% of total emissions.
- Exposure to poor air quality can lead to respiratory problems, cardiovascular diseases, and other health issues.
- In Delhi alone, vehicular emissions are responsible for 30% of particulate matter (PM) and 40% of nitrogen oxides (NOx) emissions.
Bharat Stage VI (BS-VI)
- BS-VI is India's equivalent to the European Union's Euro VI norms.
- Implemented from April 2020, BS-VI sets stricter emission standards for vehicles.
- Key features:
- 70% reduction in NOx emissions from diesel vehicles.
- 25% reduction in particulate matter (PM) from diesel vehicles.
- Mandatory use of on-board diagnostics (OBD) to monitor emissions.
Euro IV Standards
- Euro IV norms were previously followed in India before the implementation of BS-VI.
- Euro IV standards allowed higher emissions compared to BS-VI, with:
- NOx emissions: 0.5 g/km (diesel) and 0.25 g/km (petrol).
- PM emissions: 0.025 g/km (diesel) and 0.005 g/km (petrol).
Vehicle Emission Testing
- Emission testing is mandatory for all vehicles in India.
- Testing is conducted at authorized testing centers and includes:
- Emissions check: measures CO, HC, and CO2 emissions.
- Smoke test: measures particulate matter (PM) emissions.
- Vehicles that fail the test are required to undergo repairs and re-testing.
Emission Control Technologies
- Various technologies are used to control vehicular emissions:
- Catalytic converters: reduce CO, HC, and NOx emissions.
- Diesel particulate filters (DPFs): reduce PM emissions.
- Exhaust gas recirculation (EGR): reduces NOx emissions.
- Selective catalytic reduction (SCR): reduces NOx emissions.
- These technologies are mandatory for vehicles to meet BS-VI norms.

Waste Management and Swachha Bharat Abhiyan
Segregation Of Waste
- Waste segregation involves separating waste into categories: biodegradable, non-biodegradable, recyclable, and hazardous waste
- Reduces waste disposal costs, increases recycling rates, reduces environmental pollution, and helps in composting and waste-to-energy conversion
Composting
- Composting breaks down organic waste into nutrient-rich soil
- Benefits: reduces waste sent to landfills, produces nutrient-rich soil, reduces greenhouse gas emissions, and lowers waste disposal costs
- Aerobic (with oxygen) and anaerobic (without oxygen) composting methods
Sanitation Infrastructure
- Sanitation infrastructure refers to facilities and systems for managing waste and wastewater
- Importance: prevents environmental pollution, reduces health risks, improves public health and hygiene, and supports economic growth
- Types: toilets and latrines, sewer systems and wastewater treatment plants, waste management facilities
Public Awareness Campaigns
- Educates citizens about waste management and sanitation importance
- Objectives: promotes behavioral change, increases public participation, reduces littering and open defecation, and encourages sustainable practices
- Strategies: mass media campaigns, community outreach programs, school education programs, celebrity endorsements
Waste-to-energy Conversion
- Generates energy from waste through incineration, gasification, or anaerobic digestion
- Benefits: reduces waste disposal costs, generates electricity and heat, reduces greenhouse gas emissions, and supports sustainable development
- Technologies: incineration, gasification, anaerobic digestion, landfill gas capture
