energy efficient

Rail is among the most energy efficient modes of transport for freight and passengers, yet is often neglected in public debate, according to a new report published by the International Energy Agency (IEA) prepared in cooperation with the International Union of Railways (UIC).

The Future of Rail is the latest in the IEA series shining a light on “blind spots” in the energy system, which are issues that deserve more attention from policymakers.

The report was released this week in New Delhi by IEA executive director, Dr Fatih Birol, at an event opened by India’s Minister of Railways, Shri Piyush Goyal.

The transport sector is responsible for almost one-third of final energy demand, nearly two-thirds of oil demand and nearly one-quarter of global carbon dioxide (CO2) emissions from fuel combustion.

Therefore, changes in transportation are fundamental to achieving energy transitions globally.

While the rail sector carries 8% of the world’s passengers and 7% of global freight transport, it represents only 2% of total transport energy demand, highlighting its efficiency.  

“The rail sector can provide substantial benefits for the energy sector as well as for the environment,” said Dr Birol. “By diversifying energy sources and providing more efficient mobility, rail can lower transport energy use and reduce carbon dioxide and local pollutant emissions,” he added.

Evolution of the railways sector

The Future of Rail includes a base scenario that projects the evolution of the railways sector to 2050 on the basis of announced policies, regulations and projects. It also includes a high rail scenario to demonstrate the energy and environmental benefits of a more significant shift of passengers and goods to rail transport.

While the high rail scenario requires about 60% more investment than in the base scenario, global CO2 emissions from transport peak in the late 2030s, air pollution is reduced and oil demand is lowered.

The report includes a specific focus on India. “Rail serves as a vital lifeline of India, playing a unique social and economic role,” said Dr Birol.

Rail remains the primary transport mode in the country, providing vital connections within and between cities and regions, and guaranteeing affordable passenger mobility that has long been a government priority.
