• In July 2025, the Office of the Principal Scientific Adviser (PSA) to the Government of India (GoI) released a landmark report titled ‘ZET Adoption in India and Its Impact on Emission and Energy’ in New Delhi.
•  The report emphasizes the urgent need for policy support to accelerate the adoption of Zero-Emission Trucks (ZET), aligning with India's net-zero targets.
• Key Focus Areas of the Report
• Medium and Heavy-Duty Truck Sector (M and HDT):
•  The report focuses on India's Medium and Heavy-Duty Truck sector, which is projected to shift to Battery Electric Trucks (BET) by mid-century. This transition is expected to significantly reduce fuel consumption and emissions.
• Zero-Emission Trucking (ZET):
•  Promoting ZET adoption is seen as a crucial step in:
• Reducing GreenHouse Gas (GHG) emissions
• Enhancing air quality
• Improving national energy security
• Highlights of the Report
• Long-term Study and Stakeholder Collaboration:
• The findings are based on a year-long exercise involving scenario analysis and consultations with leading industries, subject matter experts, and policy stakeholders.
• Freight Sector Dominance and Impact:
• India’s freight movement, largely dominated by the M and HDT sector, contributes to around 70 percent of logistics operations.
• This sector is vital for economic growth and industrial development.
• Environmental Impact:
• Despite its importance, this sector is also a major contributor to emissions, accounting for around 40 percent of fuel consumption and significant pollution levels.
