July 24th, 2007  |  Filed under Environment

Someone wrote in to point out the Cooling Man.org site has a great list of simple things a person can do to cut their carbon footprint, so why bury the light under a bushel, as my bishop used to say? Good question, no reason, so here you go:

Direct Actions Effect on GHG (CO2eq) Estimated GHG Offset (CO2eq) Assumptions
Plant a Tree
How? – Listing of Tree Planting Organizations
1 ton absorbed per tree
(over 50-100 years)
Source
0.2 ton per tree planted 10 years growth of tree w/ 50 year lifetime (discounted due to timing and permanence concerns)
Buy Renewable Electricity for Your Home
How? – Listing of Renewable Energy Retailers
Avg. U.S. Home:
10 tons eliminated per year
1.6 lbs eliminated per kWh purchased
Source 1,Source 2
20 tons Average home, 100% renewable electricity, purchased for 2 years
Increase Home Energy Efficiency Electricity: 1.6 lbs eliminated per kWh saved
Gas: 0.1 lb eliminated per cu ft saved (117 lbs per million BTU)
Source
Case by case -
Lighting and Appliances      
Install a compact fluorescent light bulb 150 lbs eliminated per year
Source
0.4 tons Average use for 5 years
