Examine how state-level benchmarking tools launched by NITI Aayog contribute to achieving national sustainability and Viksit Bharat goals.

Since transport, road tax and electricity tariffs are State subjects, national climate targets cannot be met by central schemes alone. NITI Aayog's benchmarking indices — the latest being the India Electric Mobility Index (IEMI), a first-of-its-kind tool tracking States/UTs on EV transition [1] — seek to bridge this gap through measurement rather than mandate.

How benchmarking advances sustainability goals

• Makes targets measurable at the unit of delivery: IEMI scores states across themes of electrification, charging infrastructure and innovation, letting each state see exactly which indicator it is failing [1].
• Converts national pledges into state action: India's EV sales share stood at about 7.6% in 2024 against the 30%-by-2030 goal [2]; disaggregated ranking locates where the shortfall actually sits.
• Cooperative federalism through peer pressure: transparent comparison enables states to benchmark efforts, identify gaps and learn from each other's successes [1] — competitive federalism substituting for absent central authority.
• Signals to investors: alongside IEMI, NITI Aayog's report framed EVs as a $200 billion opportunity [3], helping states market readiness for manufacturing — the growth leg of Viksit Bharat @2047.

Limitations that blunt the contribution

• No money, no penalty: the levers that decide EV purchase — road tax, tariffs, land — remain with states. Only 19 States/UTs exempt or rebate road tax on EVs, and the Standing Committee on Industry (2023) could merely ask the Ministry to convince the rest [4].
• Implementation gap outlives measurement: of 22,000 chargers sanctioned under FAME-II, only 7,432 were installed [4]; roughly 29,277 public stations exist nationally [5].
• Comparability concerns: small, urban, affluent units score naturally higher than large rural states.
• Upstream dependence: battery minerals remain import-reliant, addressed separately via the National Critical Mineral Mission (Rs 16,300 crore, 2024-25 to 2030-31) [6].

Benchmarking is therefore a diagnostic instrument, not a delivery mechanism. Its contribution deepens when index findings are tied to fiscal incentives, a uniform road-tax rebate and mandated charging at government premises [4], so that transparent measurement matures into accountable execution towards Net Zero 2070 and Viksit Bharat @2047.
