In broad sense, it also may include all inter-company and intra- company functions such as marketing, financing, manufacturing, selling, negotiation, etc. that enable commerce and use of e-mail, fax, EDI, file transfer, video conferencing, telnet or interaction with a remote computer. The major different kinds of e-commerce are: business-to-business (B2B); business-to-consumer (B2C); business-to-government (B2G); consumer-to-consumer (C2C); B2B e-commerce is simply defined as e-commerce between companies. E-Commerce can be applied in many areas in business, like supply chain management, Electronic price book, Procurement and purchasing, etc., e-commerce is inherently neither environment friendly nor environment hostile. The technology (ICT, Internet) itself does not determine sustainability, but rather its design, use and regulations does.
