This post is for people who actually are conservationists at heart but who'd never own up to it. Haha. I got this off climatecrisis.net.
Clean or replace filters on your furnace and air conditioner
Cleaning a dirty air filter can save 350 pounds of carbon dioxide a year.
Use a clothesline instead of a dryer whenever possible
You can save 700 pounds of carbon dioxide when you air dry your clothes for 6 months out of the year.
Turn off electronic devices you’re not using
Simply turning off your television, DVD player, stereo, and computer when you’re not using them will save you thousands of pounds of carbon dioxide a year.
Unplug electronics from the wall when you’re not using them
Even when turned off, things like hairdryers, cell phone chargers and televisions use energy. In fact, the energy used to keep display clocks lit and memory chips working accounts for 5 percent of total domestic energy consumption and spews 18 million tons of carbon into the atmosphere every year!
Be sure you’re recycling at home
You can save 2,400 pounds of carbon dioxide a year by recycling half of the waste your household generates. Earth 911 can help you find recycling resources in your area.
Buy recycled paper products
It takes less 70 to 90% less energy to make recycled paper and it prevents the loss of forests worldwide.
Plant a tree
A single tree will absorb one ton of carbon dioxide over its lifetime. Shade provided by trees can also reduce your air conditioning bill by 10 to 15%. The Arbor Day Foundation has information on planting and provides trees you can plant with membership.
Buy fresh foods instead of frozen
Frozen food uses 10 times more energy to produce.
Buy organic foods as much as possible
Organic soils capture and store carbon dioxide at much higher levels than soils from conventional farms. If we grew all of our corn and soybeans organically, we’d remove 580 billion pounds of carbon dioxide from the atmosphere!
Avoid heavily packaged products
You can save 1,200 pounds of carbon dioxide if you cut down your garbage by 10%.
Eat less meat
Methane is the second most significant greenhouse gas and cows are one of the greatest methane emitters. Their grassy diet and multiple stomachs cause them to produce methane, which they exhale with every breath.
