　　Many businesses today use conferences as a means of discussing new plans of the company. As people are paying more attention to the environment and green problems，more businesses are looking for ways to reduce their negative effect on the environment.Many businesses do this by using Web conferencing.

　　Web conferencing is a technology that allows people to communicate more effectively over the Internet.It's an easy way of hosting and attending conferences without having to leave the office. Each of the people involved in a Web conference will be posted an invitation to the conference with the time and date of the Web conference on it.When the conference is ready to begin，all participants (参与者) must sit at their computers and they will be connected over the Internet.

　　With Web conferencing all participants attend the conference from the comfort of their own desk. Obviously，in doing this no fuel is used in traveling to and from a conference，and less work time is taken up in attending a conference.

　　Any material to be used during Web conferencing is simply e­mailed to all the participants before the conference.Participants can then either choose to print material or read it on screen.This not only saves paper but also greatly reduces mailing costs for the business.
