● A Smart City uses

technology and data

to improve services and

governance.

● A Green City focuses

on environmental

sustainability and

low pollution.

● Together, they create

livable, inclusive, and

future-ready districts.

● Implemented in India

under the Smart Cities

Mission (2015).

green city focuses on protecting

the environment and promoting

healthy, sustainable living by using

eco-friendly practices and

renewable resources so the city

can:

 Reduce pollution

 Save energy and water

 Protect natural resources

 Improve public health

 Ensure a better future for

coming generations

Rapid urbanization is

putting pressure on cities

to improve efficiency,

livability, and

environmental

sustainability. Smart

cities use digital

technologies and data to

optimize urban services,

while green cities focus

on minimizing

environmental impact

and promoting

sustainable living.

What is smart city?

A smart city connects

services (like transport,

energy, water,

healthcare, and

governance) using digital

tools so the city can:

 Save time

 Save money

 Save energy

 Reduce pollution

 Improve quality of life

1. Smart Waste Management

● Waste segregation at source (wet, dry, and e-

waste).

● Sensor-based smart bins and GPS-enabled garbage

vehicles.

● Composting and waste-to-energy plants at ward

level.

● Clean surroundings with minimum landfill waste.

2. Green Transportation & Mobility

● Electric buses, e-autos, and e-rickshaws.

● Dedicated cycle tracks and pedestrian-friendly

roads.

● Smart traffic signals to reduce congestion and

emissions.

● Reduced dependence on private fossil-fuel

vehicles.

3. Digital Infrastructure & Smart Governance

● Integrated command and control centers at

district level.

● Online citizen services and grievance redressal

portals.

● CCTV surveillance for safety and traffic

management.

● Transparent, fast, and citizen-friendly

governance.

4. Urban Greening & Biodiversity

● Development of urban forests, green belts, and

parks.

● Vertical gardens and green rooftops.

● Planned tree plantation with native species.

● Reduction in heat and improvement in air quality.

5. Public Participation & Awareness

● Citizen apps for reporting civic issues.

● Community cleanliness and plantation drives.

● Eco-clubs in schools and colleges.

● Citizens act as active partners in development.

6. Climate-Resilient & Disaster-Ready Cities

● Flood-resistant drainage systems and permeable

roads.

● Heat-resistant buildings and cool roofing.

● Early warning systems for floods and heatwaves.

● Improved disaster preparedness and public

safety.

7. Green Economy & Skill Development

● Creation of green jobs in solar, EVs, and waste

management.

● Skill development programs for youth at district

level.

● Support for Eco-friendly startups and innovation

hubs.

● Sustainable growth with employment

opportunities.

8. District-Level Implementation Model

● Urban areas adopt advanced smart technologies.

● Semi-urban areas use cost-effective green

solutions.

● Ward-wise planning for efficient execution.

● Public–Private Partnerships (PPP) encourage

innovation.

9. Integrated Conclusion & National Impact

● The Smart City–Green City model

combines technology with environmental

responsibility.

● It transforms national policies into real district-

level action.

● Improves quality of life while conserving resources

for future generations.

● Ensures development without environmental

destruction.

● Builds a modern, resilient, and sustainable India.

10. Clean & Renewable Energy

● Rooftop solar panels on homes, schools, hospitals,

and offices.

● Solar-powered streetlights with automatic

sensors.

Conclusion:

This research concludes that smart cities and green

cities play a vital role in achieving sustainable

urban development. By integrating digital

technologies with environmentally friendly

practices, cities can improve efficiency, reduce

pollution, and enhance the quality of life for

citizens. Although challenges suc2h as high costs

and data security remain, continuous innovation
