"Carbon Footprint Calculator" is developed with Visual Basic 6.0 in March 2010. It is the first application written by me.
The purpose of the software is to encourage people to protect the environment by decreasing carbon dioxide (CO2).
The application wins the second prize in "The Visual Basic Programming Contest in Hangzhou" (杭州市VB程序设计大赛) in 2010.
You can use the application to calculate the produced carbon dioxide in daily life, such as taking planes, driving cars, and so on.
You can get the software here. Please note that the application is in Simplified Chinese.
