In a significant development for a major infrastructure project in India's tech capital, the central government has informed the National Green Tribunal (NGT) that the proposed twin tunnel project in Bengaluru does not require prior environmental clearance. This statement comes as a direct response to concerns raised by environmental activists regarding the project's approval process.
Activists Raise Alarm Over Procedural Lapses
The project, aimed at decongesting Bengaluru's notorious traffic, had faced scrutiny from citizen groups. The activists had approached the NGT, contending that the project was being pushed forward despite alleged procedural violations. A core part of their argument was the reported lack of a mandatory Environmental Impact Assessment (EIA) process, which includes a crucial stage of public consultation.
These concerns were substantial enough to prompt the NGT to issue a formal notice to the concerned authorities, seeking their explanation on the matter. The activists' petition highlighted the potential ecological and social impacts of such a large-scale construction project in a densely populated city.
The Centre's Stance on Environmental Compliance
The central government's submission to the green court forms the crux of the latest update. Officials clarified that the Bengaluru twin tunnel project falls under a category that is exempt from the requirement of prior environmental clearance as per the existing Environmental Impact Assessment notification of 2006 and its subsequent amendments.
This legal interpretation suggests that the project proponents were not in violation of the mandated process, as claimed by the activists. The Centre's stand indicates that the necessary approvals for the project were obtained within the framework of the law, even if they did not involve the standard EIA and public hearing stages typically associated with large infrastructure works.
Implications and Next Steps
The NGT's decision, based on the Centre's submission and the activists' rejoinder, will set a critical precedent for urban infrastructure projects across India. It raises important questions about balancing rapid urban development with environmental safeguards. The tribunal's final order will determine whether the project can proceed unhindered or if it will be subject to additional environmental scrutiny.
The case, reported by Chiranjeevi Kulkarni and last updated on 21 December 2025, continues to be monitored by residents, urban planners, and environmentalists alike. The outcome will have a direct bearing on Bengaluru's future infrastructure planning and its approach to sustainable development.
