The carbon reduction research of teaching staff commuting aided by Google earth: taking Guangzhou University as an example

摘要

In this paper, taking Guangzhou University as an example, carbon reduction of teaching staff commuting was researched. Firstly, considering carbon emission of teaching staff commuting is come from the fuel consumption of vehicle used to trip, the routes, schedule, vehicle type, fuel type and fuel consumption per 100 km of service express bus, public bus and private car were investigated from relevant department and web questionnaire in office automation system. Secondly, the routes of service express bus, public bus and private car were drawn in Google earth browser to measure distance. Thirdly, combined the bus schedule, school calendar, curriculum timetable of teacher and fuel consumption per 100 km of all kinds of vehicle, the fuel consumption of service express bus, public bus and private car were computed. Fourthly, carbon emission was calculated according to net calorific factor and calorie carbon emission factors of fuel. Finally, the measures of carbon reduction were discussed. The research results show that teaching staff commuting emitted 455.433 tons carbon in 2005-2006 academic year. And reducing usage rate of private car and adding new service express bus line are efficient measure of carbon reduction. Former measure can reduce 33.6891 tons carbon and about 7.4% of original emission. The latter can reduce 7.6317 tons and about 1.68% of original emission.
