HCMC - Once in place, Hanoi’s first and second urban railway lines are expected to help reduce greenhouse gas (GHG) emissions by over 54,540 tons and 39,610 tons of CO2 emissions per year, respectively, while HCMC’s first metro line can help cut down GHG emissions by over 56,870 tons of CO2 per year, according to a survey conducted by the Japan International Cooperation Agency (JICA).

The “Data Collection Survey on development of Measurement, Report and Verification (MRV) system in urban railway sector in Vietnam” was conducted between February 2019 and September 2020, targeting the three urban railway lines, which are financed by Japan’s official development assistance loans.

The survey, successfully completed in cooperation with the Department of Climate Change, the Department of Environment under the Ministry of Transport (MOT) and the HCMC Department of Natural Resources and Environment, is considered as a scientific basis to promote low-emission means of transport such as metro lines in metropolitan areas such as Hanoi City and HCMC.

Ken Kumazawa, team leader of the survey, said that urban railways have become a daily part of Japanese life. In Vietnam, where most people use motorbikes, getting them to change to urban railways would not be easy. In the future, ensuring the quality of service and showcasing the positive environmental impacts of the urban railways will surely increase the ridership.

“Besides providing more efficient mobility, urban railways can reduce carbon dioxide and air pollutants. We hope the survey will help people understand the importance of our metro projects and more people will shift from motorbikes and private cars to urban railways in Hanoi and HCMC. The urban railway systems to be developed in Hanoi and HCMC will not only meet the public demand for transportation but also contribute to the national target of a 9% GHG emission reduction by 2030,” said Murooka Naomichi, senior representative of JICA Vietnam Office.

Speaking at the final workshop of the survey organized by the JICA Vietnam Office in Hanoi on October 23, Tran Anh Duong, director general of the MOT Department of Environment, highly appreciated JICA’s support. “The survey provided suggestions for conducting interviews with households and proposed a simple methodology with an institutional arrangement to monitor the reduction of GHG emissions in the future when the urban railways are operational,” he said.

“MOT will utilize the results of the survey for the upcoming development of the MRV system in the transport sector,” he added.

Cities such as Hanoi and HCMC are suffering from severe air pollution, leading to the deterioration of health and an increasing number of respiratory diseases. The development of urban railways is not only considered one of the potential options for GHG mitigation but also widely known as an effective solution for traffic congestion and air pollution.

The results of the interviews with households living along the urban railways, which are planned in Hanoi and are underway in HCMC revealed that a significant majority of the interviewees (81% along HCMC’s first metro line and 66% along Hanoi’s first urban railway line) expressed their willingness to use the urban railways in the future.
