Wow… Finally! I really enjoy the process of making progress on my own research path. Due to my limited resources of revealing all the factors of the increasing CO2 emission in terms of the transportation sector, I only come out of several important ones. But engaging in the process of looking at issues seriously and critically is an indispensable experience to me. Also, this paper gives me a chance to apply my knowledge from class to a field setting, in this case, China, which I always have a passion to change to a better place.
