Newsweek lists the following as their Top 10 IT Companies. I am including their 'ranking' in the list. The reality is that some of the companies are not in their "Top 10" because the list includes all industries--not just IT.
1. HP - Programs to reduce GHG and Toxic wastes in their products and supply chains.
2. Dell - Carbon Neutral, Headquarters uses 100% Renewable energy, computer products use 25% less power (by 2010).
4. Intel - focus is on increasing speed while reducing energy usage in their products.
