Delhi leads electric-mobility index, but charging and adoption progress unevenly
Where it stands
Delhi leads the India Electric Mobility Index 2025, launched by NITI Aayog on 16 September 2026. Maharashtra and Karnataka follow in the overall ranking. The index examines how states and Union Territories are advancing electric transport through adoption, charging readiness and research. Delhi’s score of 84 is a composite index score, not a claim that 84% of its vehicles are electric. The report shows why one headline ranking is not enough. Karnataka leads the charging-readiness dimension, while strong charging performance does not always coincide with equally strong vehicle adoption. Haryana illustrates that gap, scoring 91 for charging readiness but 19 for transport-electrification progress. The policy question is therefore not only whether infrastructure exists, but how the wider transport system encourages its use. The index identifies differences; it does not prove that one factor caused every state’s result.
Background
Replacing petrol or diesel vehicles with electric vehicles involves more than making a new type of vehicle available. Users need suitable charging arrangements, and transport services need ways to operate electric fleets reliably. States influence this transition through transport policy, electricity arrangements, industry support and urban planning. Their decisions can therefore produce different conditions even when national schemes are the same. NITI Aayog and WRI India developed the index to compare this progress. It brings together 16 indicators under three themes. Transport-electrification progress carries half the overall weight, charging readiness carries 30%, and research and innovation carries 20%. Combining these themes gives a broad comparison, but can also conceal a weakness in one area behind strength in another. The report separates enabling conditions from observed outcomes. A policy or support mechanism can help a transition, but is not the same as vehicles actually being adopted. Haryana’s contrasting theme scores make this distinction concrete. The gap is a reason to investigate other barriers and implementation, not proof that installing chargers has no value. The edition assesses progress during 2025, even though it was released in September 2026. Its comparisons with 2024 also need care because the methodology changed. The new edition groups jurisdictions by their circumstances and adjusts aspects of measurement. A movement in rank can therefore reflect policy progress, changes elsewhere and changes in measurement. It should not automatically be described as an equivalent rise or fall in vehicle sales.

The second index reveals different strengths behind the overall rankings
Delhi scores 84, Maharashtra 78 and Karnataka 73 on the overall index. Chandigarh and Goa complete the five jurisdictions in the top-performer category. Karnataka’s charging-readiness score is 97, the highest nationally. These results show that the overall leader need not lead every individual theme. The median overall score rose from 36 in the previous edition to 40. That indicates a higher middle value across jurisdictions, not a 40% national electric-vehicle share. The report also links some ranking changes to revisions in the assessment method. States can use the underlying indicators to identify what needs attention instead of treating the league table as a complete diagnosis.
Why it matters for UPSC
For GS2 and GS3, connect state-level policy with clean transport and cooperative federalism. Distinguish infrastructure readiness, actual adoption and research capacity. An index score is not a vehicle-share percentage, and a change in rank requires attention to methodology as well as performance.
