- The ministry has asked the Automotive Research Association of India to run flex‑fuel and vehicle tests that can assess engines on fuels with up to 100% isobutanol.
- Bharat Petroleum has begun strategic trials and reported very encouraging initial results showing lower pollution and operational compatibility with existing diesel engines.
- MoRTH will shortly publish a draft notification on truck‑trailer interchangeability to ease battery‑swap and charging challenges for heavy electric trucks by allowing the tractor unit to be swapped.
- Separate pilots for hydrogen buses, expansion of barrier‑free tolling, and calls to fast‑track multimodal logistics parks reflect a wider push to cut freight emissions, improve fuel security, and lower logistics costs.
