CMI: Building and Appliance Efficiency

Continuing our segment on the Carbon Mitigation Initiative, Green Factoids will consider in more detail the areas which might be capable of providing a whole or partial wedge. In several papers, lead scientists Stephen Pacala and Robert Socolow outline 15 options, each of which could produce one wedge if fully deployed. Seven wedges are needed in order to stabilize the atmospheric CO2 concentrations. Each wedge represents the reduction of 25 billion tons CO2 over the next 50 years, or 1 billion tons per year by 2054.


Energy Efficient Buildings:

Roughly one wedge could be achieved if we install the most efficient lighting, appliances, space heating and cooling, and water heating, and improve insulation in every new and existing building by 2054. Doing so would reduce CO2 emissions by buildings by about one quarter.

One half of these savings are in buildings in developing countries.

They estimate that approximately one quarter of a wedge could be achieved just by switching all incandescent bulbs to CFL's.
