6.Employees contribute to carbon footprint: Workers who keep refrigerator doors open, use more electricity and don’t recycle contribute more in terms of carbon dioxide emissions. Ways to be more efficient include making bicycle use more accessible and encouraging employees to work at home.
7.Electricity = Carbon Dioxide – like it or not, every time you plug in, you are impacting the environment through carbon emissions. Power plants all over the world utilize fossil fuels, coal, and alternative energies such as nuclear, wind, water, and solar. Unfortunately there is still a carbon impact. Even discarded batteries from laptops or cell phones can leave a deadly impact in landfills. Consider unplugging for one day, or even a few hours, each week. Find an activity that does not involve electricity, and enjoy it.

8.Sources of CO2 – the primary sources of carbon emissions are

9.Paper – the more paper you use, the more you are contributing to deforestation and carbon emissions. Try switching to paperless billing as much as possible, and consider using recycled paper for sending cards, letters or wrapping gifts. If possible, use gift bags and other paper goods more than once to reduce the overall need for paper. Also unsubscribe to junk mail and catalogs that can be found online instead.

10.Less Driving – park your car once a day if possible and work from home or just walk to your destination. Carpooling is a great way to help reduce carbon emissions while also providing you with networking opportunities.

-Heating and cooling: Air conditioners and heaters not only use electricity, cooling systems also include refrigerants that contain hydrochlorofluorocarbons that act as greenhouse gases and ozone depleting agents. Refrigeration has been a major source of these in the past, although recent advancements are reducing emissions.

-Appliances: Refrigerators, clothes dryers, and computers are known energy guzzlers. Even when an appliance is turned off, it can still use power when plugged in. Unplugging devices can help reduce CO2 emissions, but Energy Star products are notable for consuming less power and therefore reducing one’s carbon footprint.

-Food consumption: Food production accounts for 83 percent of carbon dioxide equivalent emissions, or 8.1 metric tons each year, according to a study published in Environmental Science & Technology. Transporting food accounts for 11 percent of emissions. Businesses that produce food contribute to carbon dioxide, methane, and nitrous oxide emissions, including the methane released by animals such as sheep, cattle, and goats. By eating locally grown food, the equivalent of driving 1,000 miles can be saved in a year.
- Use of auto fuel: Burning automotive fuel contributes to emissions, but the exact amount depends on the fuel type. A UK gallon of petrol contributes 10.4 kilograms of CO2 per unit, while a USA gallon of gasoline contributes 8.7 kilograms. In the U.S., a gallon of diesel fuel yields 9.95 kilograms, and a gallon of heating oil, 11.26 kilograms of CO2  per unit.
- Traveling by bike or foot emits a fraction the CO2 of a car: By driving two miles, 0.88 kilograms of carbon dioxide is released into the air, but walking the same distance only releases 0.039 kilograms and riding a bicycle just 0.017 kilograms of carbon dioxide.

- Improving fuel economy reduces one’s carbon footprint: Driving at the speed limit can improve fuel economy by 7 to 14 percent. Not only does driving faster contribute to higher amounts of burned fuel and emissions released. At a speed over 50 miles per hour, every five mile-per-hour increase in fuel is equal to a cost value of $0.15 to $0.30 extra for each gallon burned.
-People emit more carbon dioxide than volcanoes: According to the National Oceanic and Atmospheric Administration, humans emit about 40 billion metric tons of carbon dioxide, based on 2015 numbers. Emitting CO2 via eruptions and underground magma (through vents, soils, porous rocks, and water), volcanoes emit up to 0.15 billion metric tons of carbon dioxide annually, or around 90 times less than people do.

- Buildings emit 39 percent of the CO2 released in the U.S.: Lighting, heating, and cooling buildings contribute to emissions, as do the electrical appliances and equipment used by building occupants. Consuming 70 percent of the nation’s electricity, structures account for more emissions than the industrial or transportation sectors, according to the U.S. Green Building Council.

2. One ham sandwich has a carbon footprint of 14 to 34 grams of CO2.

3. You save massive amounts of water – 3,000 to 5,000 gallons of water for every pound of beef you don't eat!

4. Eating less meat avoids pollution of our streams and rivers better than any other single recycling effort you do.

5. You avoid making the destruction of topsoil by eating less meat.

6. Destruction of tropical forest is caused by meat production.

7. According to "How Our Food Choices can Help Save the Environment" by Steve Boyan, a PhD in Political Sciences- An average car produces 3 kg/day of CO2 and the production of one hamburger produces 75 kg of CO2.

8. Also according to "How Our Food Choices can Help Save the Environment" by Steve Boyan, a PhD in Political Sciences- Eating one pound of hamburger does the same damage as driving your car for more than three weeks.

9. By eating less meat you reduce the amount of methane gas produced.

10. By eating less meat you also reduce the destruction of wildlife habitat, and help to save endangered species.

In other words: When you drive a car, the engine burns fuel which creates a certain amount of CO2, depending on its fuel consumption and the driving distance. (CO2 is the chemical symbol for carbon dioxide). When you heat your house with oil, gas or coal, then you also generate CO2. Even if you heat your house with electricity, the generation of the electrical power may also have emitted a certain amount of CO2. When you buy food and goods, the production of the food and goods also emitted some quantities of CO2.

Consuming 70 percent of the nation’s electricity, structures account for more emissions than the industrial or transportation sectors, according to the U.S. Green Building Council.About 21 percent of U.S. greenhouse gas emissions came directly from industrial processes in 2015: Businesses that produce goods from raw materials burn fossil fuels directly from the energy they use. The chemical reactions that occur during production contribute to greenhouse emissions as well. By comparison, commercial and residential activities accounted for 12 percent of emissions that year.
