CM drops second Chennai airport plan for now
Tamil Nadu's CM announced scrapping the Parandur airport project, citing environmental concerns and impacts on farmers, and promised alternative sites with feasibility studies. Meanwhile, Meenambakkam airport will be expanded to improve capacity ahead of any new project.
Key takeaways
- The Parandur airport project in Kancheepuram was scrapped by the current Tamil Nadu government.
- Environmental and farmer livelihood concerns were central to the decision.
- Meenambakkam airport will be expanded, with Terminal 3 and Terminal 5 increasing overall capacity.
- Alternative sites will be studied with technical feasibility before finalizing any new airport location.
- There was political backlash, including a DMK walkout, over the Parandur discussions.
What Happened
The chief minister, C Joseph Vijay, announced the cancellation of the proposed second Chennai airport project at Parandur in the Kancheepuram district. This follows years of debate over ecological impact and the livelihoods of local farmers tied to paddy cultivation on land earmarked for the project. The 2022 proposal had envisaged a site roughly 60km west of Chennai, with an estimated project cost of 20,000 crore and an annual passenger capacity of 100 million. The government stated that it would examine alternative sites that would minimize damage to agricultural land and populations. In parallel, Vijay indicated that the existing Meenambakkam airport would be expanded to handle more passengers, and that a new terminal (Terminal 3) would allow capacity growth to 35 million, with Terminal 5 lifting total capacity to 55 million once completed.
Vijay had earlier engaged with Parandur residents, visiting the area in 2025 to hear grievances and emphasizing that development must not come at the expense of farmers. The move also prompted political discord, with the opposition DMK staging a walkout when the Parandur project was discussed in the state assembly.
Why It Matters
The decision shifts Tamil Nadu’s aviation strategy away from a large greenfield project in Parandur toward expanding and optimizing the current hub at Meenambakkam, potentially reducing displacement risks for farmers and protecting agricultural land. The commitment to alternative sites and feasibility studies signals a calibrated approach to meeting future travel demand while balancing environmental and rural concerns.
Background
The Parandur plan was first announced in August 2022 by the previous government under M K Stalin. The project faced protests over ecological impacts and threats to water bodies, raising questions about land suitability for runways and the livelihoods of nearby farmers. The current administration has prioritized environmental considerations while presenting a transitional path that includes upgrades to the existing airport infrastructure and a careful site selection process for any new facility.
Key Facts
- The Parandur project was proposed to be located about 60km west of Chennai, in Kancheepuram district.
- Estimated cost of the Parandur airport was 20,000 crore with an anticipated annual capacity of 100 million passengers.
- Protests over Parandur centered on ecological concerns and the impact on local farmers who cultivate paddy on land slated for the airport.
- The Meenambakkam airport will be expanded to handle an additional 20 million passengers per year, once operational.
- Terminal 3 at Meenambakkam will enable a capacity of 35 million passengers per year, and Terminal 5 is expected to raise total capacity to 55 million passengers per year after its operation.
- The DMK opposition staged a walkout during a discussion on Parandur in the state assembly.
- Vijay visited Parandur in 2025 and expressed support for farmers and the need to avoid large-scale displacement.
- Suitable alternative sites have been identified or selected as part of the plan, with technical feasibility studies to follow before finalizing a location.
What Happens Next
The government says it will carry out technical feasibility studies for the newly proposed sites and select options that minimize agricultural land impact and displacement. It did not specify a timetable for building a new airport, indicating that the Meenambakkam expansion and interim enhancements will proceed as needed while site studies continue.
