Green communications portfolios of products and services exist today—though they are not being marketed as such—and this study puts a dollar value on the assembling and marketing potential portfolios that aid the environment.

Communicating Green identifies several key domains in which telecommunications applications can have a direct, tangible impact on lowering greenhouse gas emissions, power consumption, and achieving efficient recycling of equipment waste. For example, transportation demand management systems can cut down greenhouse gases produced by cars and trucks by leveraging location-based services, unified communications services, mobile resource management systems, and fleet management systems. Several major domains are identified and a forecast of carrier revenue related to these applications portfolios is provided.
