The 12 Principles of Green Chemistry, published by Paul Anastas and John Warner in Green Chemistry: Theory and Practice (Oxford University Press: New York, 1998) provide a road map for chemists to implement green chemistry.

Green chemistry technologies provide a number of benefits, including: Reduced waste, eliminating costly end-of-the-pipe treatments, Safer products, Reduced use of energy and resources, Improved competitiveness of chemical manufacturers and their customers.

12 Principles of Green Chemistry

1. Prevent waste
2. Design safer chemicals and products
3. Design less hazardous chemical syntheses
4. Use renewable feedstocks
5. Use catalysts, not stoichiometric reagents
6. Avoid chemical derivatives
7. Maximize atom economy
8. Use safer solvents and reaction conditions
9. Increase energy efficiency
10. Design chemicals and products to degrade after use
11. Analyze in real time to prevent pollution
12. Minimize the potential for accidents

Dell has became the first in its industry to achieve 80 PLUS Gold-certification for a server power supply, the latest sign that the company is meeting its goal of becoming the “greenest” technology company on the planet and strengthening its position as an energy-efficiency leader.

The 80 PLUS Gold-certification enables manufacturers and customers to compare and contrast power supplies based on established criteria from Energy Star and the Climate Savers Computing Initiative. Dell’s new 80 PLUS Gold power supply meets July 2009 Climate Savers targets for servers more than a year ahead of schedule, which require 92 % minimum efficiency for the power supply unit at 50 percent of rated output.

Servers, personal computers and monitors account for more that 60 % of global ICT-related carbon emissions.

In May, Dell said it plans to reduce the energy consumption of its products and avoid millions of tons of CO2 emissions worldwide by designing its laptops and desktops to consume up to 25 percent less energy by 2010.
