根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
The use of fossil fuels in transportation is one of the major reasons for climate change. A survey by the Asian Development Bank indicates that Asia's carbon dioxide emissions from transportation increased 3.9 percent yearly, nearly twice the global level.
If left unchecked, emissions from transport will continue to rise. By 2050, Asia's demand for transportation will likely double from the current level. They should aim to achieve the low-carbon goal in transportation.
For example, the energy efficiency in transport systems is dissatisfying and dependence on high-carbon energy resources is heavy. The Institute for Transportation and Development Policy (ITDP) proposed several strategies for Asian cities to become low-carbon in transport.
First, shorten travel time and distance. City planning should be focusing on reducing people's travel time as well as cutting carbon emissions through practical measures. They also have introduced " 15-minute life circles" to shorten travel time and distance.
Second, improve transportation structure. It is important to encourage the use of low-carbon transportation means and reduce high-emissions vehicles. Most Asian cities including Yichang in China and Jakarta in Indonesia are not large and thus suitable for building effective and economic public transit systems. These successful practices have set up examples for other Asian cities to follow.
Third, promote the use of clean energy. Public vehicles such as taxis, shared cars, service cars, and sanitation vehicles should be the first to stop using fossil fuel and go electric, followed by private cars, trucks and ships.
As the continent with one of the largest number of developing economies, Asian is key to pushing the global low-carbon transition. With regional joint efforts, the transition could be more practical and hopeful.
A. To carry it out requires promoting the use of clean energy.
B. However, there are multiple challenges to be overcome.
C. To achieve the low-carbon goal, strategies should be adopted.
D. Bus Rapid Transit （BRT） systems in some Asian cities has been promoted.
E. This strategy is to increase the efficiency of energy in transportation and reduce emissions.
F. It is important for countries here to solve environmental problems caused by transportation.
G. Many Asian cities have introduced online education and remote working during the COVID- 19.
