The 21st Conference of the Parties (COP21) at the United Nations Framework Convention on Climate Change was held at the end of 2015 and the Paris Agreement was adopted as a new framework for global warming measures from the year 2020. It will see all countries involved, taking a proactive role and setting their own targets for reducing greenhouse gases. This includes ASEAN nations.

Approximately 25% of CO2 emissions in the world stem from the transport sector and within this category, 75% of CO2 emissions come from the road transport sector.

To effectively reduce these emissions from the road transport sector, it’s important that auto makers, fuel companies, governmental bodies and the road users themselves, play their respective roles and take an integrated approach in 4 key areas. They are:

  • Improved fuel efficiency
    • Auto makers need to develop and introduce vehicles with superior efficiency that use alternative fuels such as electricity, natural gases, fuel cells and hybrid technology.
    • Governments need to implement measures such as tax incentives and subsidies to promote fuel-efficient vehicles.
  • Efficient usage of vehicles
    • Road users like general drivers are encouraged to practice eco-driving and in the freight transport sector, eco-driving management systems are introduced to improve load efficiency.
  • Alternative automotive fuels
    • Fuel companies, governmental bodies and academic institutions need to effectively promote the widespread use of electric vehicles and fuel cell vehicles, along with the establishment of supply systems like charging facilities and hydrogen stations.
    • Fuel suppliers can plan the addition of alternative fuels such as bio-fuel.
  • Improved traffic flow
    • Governmental bodies must plan and carry out congestion-mitigating measures such as the development and improvement of road infrastructure along with the use of ITS technology. This will be achievable by taking traffic measures in the early stages of urban-planning into consideration.

Taking Japan as an example, measures in the 4 areas are contributing greatly to the decline of CO2 emissions in the transport sector. In addition, efforts are being made to improve fuel efficiency of new vehicles, but because the average vehicle life there is 10 to 20 years, it will take a long time to see a significant result.

On the other hand, improvement in the load efficiency of freight transport and the promotion of eco-driving practices are gaining positive results. It has already contributed significantly to CO2 reduction in a short period, since it can be applied to existing vehicles.

The practice of eco-driving by all drivers can significantly reduce CO2 emissions. Eco-driving is a driving method to reduce fuel usage and It includes accelerating gently when starting a vehicle, avoiding unnecessary acceleration or deceleration by maintaining a suitable distance from other vehicles and releasing the accelerator ahead of time when decelerating.

It is an extremely effective method as it not only results in CO2 emission reduction, but also contributes to improvements in traffic safety and fuel economy.

JAMA will share the importance of the integrated approach with stakeholders of the ASEAN nations and make its best efforts to better reduce CO2 emissions.
