Carbon Footprint

There are many simple ways to reduce the footprint you leave on the planet. Learn how to reduce your footprint in each consumption category–carbon, food, housing, and goods and services—but don’t stop there. Amplify your impact by encouraging others to follow your lead. Engage your friends and community with local and global movements for social change, or start your own movement!

Reduce your Carbon Footprint

Use cleaner transport

• Walk, bike, or take public transit whenever possible.
• 
  Avoid allowing your car to idle. If you’ll be waiting for more than 30 seconds, turn off the engine (except in traffic). And don’t take the drive-through—park the car and walk inside instead.
• 
  Have your vehicle serviced regularly to keep the emission control systems operating at peak efficiency. Check your car's air filter monthly, and keep the tires adequately inflated to maximize gas mileage.
• 
  Avoid short airplane trips—take a bus or train instead.

Add energy-saving features to your home

• Install compact fluorescent bulbs in all your home light fixtures—but remember, compact fluorescents contain mercury, so look for low-mercury models and be sure to dispose of old bulbs safely through your local hazardous waste program.
• 
  Weatherproof your home. Make sure your walls and ceilings are insulated, and consider double-pane windows. Eliminate drafts with caulking, weather strips, and storm windows and doors.
• 
  Insulate your water heater. Even better, switch to a tankless water heater, so your water will be heated only as you use it.
• 
  Choose energy efficient appliances.

Adopt energy-saving habits

• 
  Keep thermostat relatively low in winter and ease up on the air conditioning in summer. Clean or replace dirty air conditioner filters as recommended to keep the A/C operating at peak efficiency.
• 
  Unplug your electronics when not in use. To make it easier, use a power strip. Even when turned off, items like your television, computer, and cellphone charger still sip power.
• 
  Dry your clothes outside whenever possible.
• 
  Make minimal use of power equipment when landscaping.
• 
  Defrost your refrigerator and freezer regularly.
• 
  Choose green electricity. Many utilities give you the option to purchase electricity generated by wind and solar power for a small rate surcharge.
• 
  Purchase carbon offsets to make up for the energy use you can’t eliminate.

Reduce your Food Footprint

• 
  Eat more local, organic, in-season foods.
• 
  Plant a garden—it doesn’t get more local than that.
• 
  Shop at your local farmer’s market or natural foods store. Look for local, in-season foods that haven’t traveled long distances to reach you.
• 
  Choose foods with less packaging to reduce waste.
• 
  Eat lower on the food chain—going meatless for just one meal a week can make a difference. Globally, it has been estimated that 18% of all greenhouse gas emissions are associated with meat consumption.

Reduce your Housing Footprint

Choose sustainable building materials, furnishings, and cleaning products.

• 
  Explore green design features for your building, like passive solar heating, a rainwater catchment or grey water recycling system, and recycled materials.
• 
  Choose efficient appliances, including low flow shower heads, faucets, and toilets.
• 
  Choose furnishings that are second-hand, recycled, or sustainably produced.
• 
  Plant drought tolerant plants in your garden and yard.
• 
  Use biodegradable, non-toxic cleaning products.

Adopt water-saving habits

• 
  Take shorter, less frequent showers—this not only saves water, but the energy necessary to heat it.
• 
  Don’t use the garbage disposal. Compost instead.
• 
  Run the dishwasher and the laundry machine only when full.
• 
  Wash cars rarely, or better yet, take them to a carwash. Commercial carwashes use less water per wash than home washers, and they are also required to drain used water into the sewage system, rather than storm drains, which protects aquatic life.
• 
  Avoid hosing down or power-washing your deck, walkways, or driveway.
• 
  Regularly look for and fix leaks.

Reduce your Goods and Services Footprint

• 
  Buy less! Replace items only when you really need to.
• 
  Recycle all your paper, glass, aluminum, and plastic. Don’t forget electronics!
• 
  Compost food waste for the garden. Garbage that is not contaminated with degradable (biological) waste can be more easily recycled and sorted, and doesn't produce methane gases (a significant greenhouse gas contributor) when stored in a landfill.
• 
  Buy recycled products, particularly those labeled "post-consumer waste."
  

Causes and Effects of the Global Warming

There are several effects of the global warming. One of them is raising sea levels. With increasing average global temperature, the water in the oceans expands in volume, and the water enters them which had been locked up on land in glaciers. Another effect is that the glaciers are retreating. Glacier retreat declined and reversed in many cases from 1950 to 1980 as a slight global cooling occurred. Arctic shrinkage, and altered patterns of agriculture are cited as direct consequences, but predictions for secondary and regional effects include extreme weather events, are also examples of the global warming effects.

There are many causes of global warming. The major cause of global warming is the emission of green house gases like carbon dioxide, methane, nitrous oxide etc into the atmosphere. The major source of carbon dioxide is the power plants. These power plants emit large amounts of carbon dioxide produced from burning of fossil fuels for the purpose of electricity generation. In developed countries, building structures require a lot of fuel to be burnt which emits a large amount of carbon dioxide in the atmosphere. Another cause of global warming is deforestation that is caused by cutting and burning of forests for the purpose of residence and industrialization.
