Considering the Issues of Achieving Carbon Neutrality in the Automotive Sector
-Focusing on Heavy-Duty Vehicles-

Shuichi Kanari･Hiroshi Hirai･Yuka Sato･Tetsuya Suzuki･Akiyoshi Ito (JARI)

The authors have developed CAMPATH, a quantification method for long-term CO2 emissions and co-benefit effects targeting the automotive sector. This paper aims to examine the challenges in achieving carbon neutrality, focusing on heavy-duty trucks and buses, using the scenario analysis results.

Research on Customer Acceptance of CO2 Extraction Behavior in Vehicles with CO2 Capture Technology

Kenji Uchida･Masahiro Horikoshi･Akiko Miura･Chikara Tanaka･Yuji Harada (Mazda)

In vehicles with CO2 capture technology, customers may need to extract CO2 from the vehicle. This study evaluates customer acceptance of such vehicles by quantifying the effort required for the extraction process and the measures to reduce this effort, using a survey and monetizing the results.

Applicability of moisture swing adsorption for CO₂ capture from engine exhaust

Yusuke Osawa･Ibuki Matsubara･Satoshi Sakaida･Kotaro Tanaka (Ibaraki University)

To capture CO₂ from exhaust gas of automobile, CO2 adsorption at high temperatures is desirable. Therefore, this study focuses on the moisture swing adsorption, which enables CO₂ adsorption and desorption by controlling the water content of the adsorbent, without the need for heat during desorption. The applicability of this method under high-temperature conditions was investigated.

Project to Develop and Promote Next-Generation Heavy-Duty Vehicles through Industry-Academia-Government Collaboration toward Carbon Neutrality

Tomoki Takashima (Logistics and Road Transport Bureau)

Regarding trucks and buses, which account for approximately 40% of CO2 emissions from the transport sector, the Ministry of Land, Infrastructure, Transport and Tourism, through collaboration between industry, academia and government, is working to achieve "Carbon Neutrality in 2050" by strengthening the promotion of 1) electrification technology for large vehicles and 2) development of internal combustion engines that use carbon-neutral fuels, including hydrogen and synthetic fuels.

LCA for electric vehicles in traveling stage in line with Paris Agreement

Each country has different energy sources and CO2 emissions during power generation. Based on the Paris Agreement, each country plans to achieve zero emissions, and it can be predicted that the environmental impact of power generation will decrease. In this study, the reduction in the CO2 emission intensity of power generation in the seven major automobile producing countries was predicted until around 2050. The reduction in the environmental impact of electric vehicles during their lifetime traveling was also predicted by LCA in each country.
