the increased price of raw material and the level of governmental
subsidy and pressure from international rules, the amounts of
firms' carbon emissions changed slightly. Meanwhile, the simulation
also indicated an interesting result that with the increased firm's
awareness of social responsibility, its carbon footprint changed
slightly, too. On the contrary, according to the results, some factors
have obvious effects on firms' carbon footprint including pressure of
governmental regulation, low carbon awareness of consumer, low
carbon substitute product's price, willingness of using low carbon
energy, company size, the ratio of low carbon package and recycling,
as well as the development of landfill technology and awareness of
manager.
