Chennai's Green Growth in 2025: How the City Is Getting Greener and Smarter
Chennai is working hard to become a greener, cleaner, and more livable city. In 2025, several projects are underway to improve green spaces, reduce pollution, and make the city more climate-friendly. A big step in this direction is the Brigade Group's recent purchase of 5.4 acres of land on Velachery Road for ₹441.7 crore. This land may soon become home to a new sustainable development with eco-friendly buildings and green infrastructure. South Chennai is also seeing similar growth—Prestige Pallavaram Gardens, located in Pallavaram along the Pallavaram-Thuraipakkam Road, is designed with open spaces and nature-based planning to support a healthier lifestyle.
Chennai has less green space compared to other major Indian cities. Right now, only about 5.28% of the city's area is covered in greenery. This is far below the national goal of 33.3%. For comparison, Bengaluru has around 6.8%, while Delhi and Hyderabad have over 12%.
To improve this, the city launched an ambitious plan to plant more trees and add green zones where possible. Starting June 5, 2025—World Environment Day—the Greater Chennai Corporation is planting 1 lakh saplings across public places like crematoriums, parks, roadways, and apartment complexes.
- In vacant areas like Mylapore and Manali
- Around apartment buildings and parks
- Along busy roads to help with shade and air quality
The city wants everyone to get involved—residents, schools, businesses, and colleges.
- Crematorium Plantations: So far, 250 trees have been planted in the Manali burial ground. The plan is to green all 212 crematoriums across the city's 15 zones.
- Railway Efforts: In 2024, Southern Railway planted over 2,300 saplings at stations and employee housing areas.
- College Projects: SRM College of Pharmacy helped plant over 100 trees in Kolathur village, as part of a rural development program.
Many small community efforts are also happening. People are planting trees on birthdays, festivals, or during social drives like "Grow Billion Trees."
The city isn't just planting trees—it's planning how to fight climate change in the long run. In June 2023, the city launched the Chennai Climate Action Plan (CAP). It includes:
- Carbon Neutral by 2050
- 1% emission cut by 2030 and 40% by 2040
- Better systems to handle floods, cyclones, and heat
This plan follows the Paris Agreement goals, putting Chennai ahead of many other cities.
To support its goals, Chennai is changing how it plans buildings, roads, and neighborhoods.
- Greenprint for Chennai: This project, by CMDA and Nature Conservancy India, is part of the city's new master plan for 2026–2046. It focuses on improving parks, saving wetlands, and protecting water bodies.
- Climate Labs: With help from C40 Cities, the city is using data and expert advice to design better roads, housing, and transport that support the environment.
A study by CSTEP found that spending ₹2,203 crore on nature-based solutions like rooftop gardens and water body restoration could boost the city's green cover by 76% and save ₹500 crore yearly in flood damage costs.
With little open space left, Chennai is trying new ways to add greenery:
- Rooftop Gardens: People are turning rooftops into gardens. One resident, S. Veeralakshmi, now grows hundreds of plants on her roof and has helped over 1,500 others do the same.
- Mini Forests (Miyawaki Method): The city is using this Japanese technique to grow small, dense forests in areas like old dump sites. These mini-forests clean the air and support birds and insects.
- Smart City Projects: The city has restored 32 out of 210 planned water bodies. It has also built vertical gardens and parks in busy areas where space is limited.
Builders in Chennai are responding to the shift in public interest toward greener living. Brigade Group's land acquisition may lead to climate-friendly homes and offices with:
- Solar panels and energy-efficient lights
- Rainwater harvesting systems
- Walkways, cycle paths, and open public areas
Similarly, Prestige Pallavaram Gardens in Pallavaram is designed for people who care about clean air, green surroundings, and modern comforts. Located on the fast-growing Pallavaram-Thuraipakkam Road, this community reflects what future-ready housing in Chennai looks like.
While progress is happening, Chennai has seen some tough moments too:
- Cyclone Michaung (Dec 2023): This storm damaged many trees across the city. Experts found a big drop in healthy vegetation afterward. Tree replacement and monitoring work is still ongoing.
- Green Cover Loss (2013–2022): A study found that Chennai lost 13.3% of its vegetation in less than 10 years. This raised surface temperatures and made heat waves worse.
These setbacks show why the city's current efforts are so important.
Chennai is taking real steps to become a greener, healthier place to live. With major planting drives, smart climate planning, and green buildings, the city is setting an example for others.
Builders like Brigade Group and Prestige Group are not just putting up new buildings—they're creating better places to live. Projects like Prestige Pallavaram Gardens show how homes can be built with care for both people and the planet.
Because the city has very little green space—just 5.28%. Trees help improve air, reduce heat, and prevent floods.
It's a long-term plan to make Chennai carbon neutral by 2050 and better prepared for floods and heatwaves.
They are small, dense forests that grow fast and support local wildlife, using a special Japanese method.
Yes. You can take part in plantation drives, start a rooftop garden, or join local green groups.
Yes. Many builders now include solar panels, rainwater systems, and green spaces in their designs. Prestige Pallavaram Gardens is one such example in South Chennai.
