To prevent global warming, there is a rapid increase around the world in the number of initiatives aiming to switch from gasoline-powered vehicles to those powered by electricity and other cleaner energy sources. The Japanese government also must accelerate efforts toward this goal in tandem with the private sector.

 

The Economy, Trade and Industry Ministry is set to compile a target of making all new cars sold domestically to be electrified, such as electric vehicles (EVs), by the mid-2030s.

 

The government aims to achieve net-zero greenhouse gas emissions by 2050. In fiscal 2018, 16% of Japan’s carbon dioxide emissions came from automobiles. To achieve the emissions goal, it is essential for the nation to shift to electrified vehicles.

 

The United Kingdom will ban the sale of new gasoline cars by 2030, with hybrid vehicles also to be subject to the measure in 2035. In the United States, the state of California will reportedly ban the sale of new gasoline-powered cars, including hybrids, by 2035. China, the world’s largest automobile market, also plans to make EVs the mainstay of new car sales by that year.

 

While Tesla Inc. of the United States and other manufactures overseas are increasing their sales of EVs, Japanese automakers have low presence. For Japan to be left behind in this field, it will likely lose its competitiveness in the automobile industry, a key sector for the nation, causing Japan’s entire economy to be hit hard.

 

According to the industry ministry’s definition, electrified vehicles include not only EVs and fuel cell vehicles, which are powered by hydrogen, but also hybrids and plug-in hybrid vehicles that can be recharged at home.

 

Of new cars sold in Japan in 2019, nearly 40% were electrified vehicles according to the definition, but most of them were hybrids, which also use gasoline. As long as the government aims to achieve net-zero greenhouse gas emissions, the focus of its support should be EVs and fuel cell vehicles.

 

In providing such support, there are many issues involved, such as lowering the relatively high prices for these products and increasing the number of charging facilities and hydrogen refueling stations.

 

Innovations in battery technology, a key component of EVs, is also important. Japanese makers, which used to have an edge in developing batteries, have been losing ground to their Chinese and South Korean rivals.

 

Batteries directly affect the performance of electric vehicles and account for about 30% of the total manufacturing costs, therefore, they determine the prices for EVs. It is hoped that expanding support for production and development of these vehicles will help lower their prices and extend their traveling distance on a single charge.

 

Japan notably lags behind other countries in the number of quick charging stations. The government should take the initiative in accelerating the setting up of such facilities.

 

Toyota Motor Corp. has mass-produced fuel cell vehicles, a world first. Japan reportedly has an advantage in hydrogen technology. Although there are still a few hydrogen refueling stations, it is easy to introduce this type of vehicle for trucks and buses as many of them run on fixed routes. It is necessary to devise effective measures to promote fuel cell vehicles.

 

Even if more and more EVs run on roads, effects would be limited unless power plants can reduce greenhouse gas emissions. It is important to expand the use of renewable energy and restart nuclear power generation.
