Carbon Footprint Essay
Over the years footprints have been used to tell the details of the species that marked it. In the case of carbon footprint it is the amount of Carbon Dioxide or other carbon compounds (green house gases) emitted into the atmosphere by human activities. By simply going about our daily lives of driving to work or running home appliances we are producing more CO2 because each is powered by energy that rely on the combustion of fossil fuels. The burning of fossil fuels by humans emits 98% of the CO2 in the atmosphere making it the largest source of Carbon dioxide emissions and so it is a major cause of global warming (Dowdey, 2013). Fossil fuels include coal, petroleum, and natural gas (Sciencedaily.com, 2013). Carbon dioxide releases have increased intensely in the last 50 years and it is still increasing by about 3% each year. Because CO2 can remain in the atmosphere for 100 to 200 years its concentration eventually increases and causes the Earth’s temperature to rise (Rohrer,2013).
The United Arab Emirates is a very important oil producer making it one of the 10 largest oil and natural gas manufacturers in the world, and so it has a huge carbon footprint even with its low population (Todorova, 2013). The UAE’s dependence on fossil fuels to run cooling systems through the entire year, and the use of desalination plants to produce drinking water has raised their concerns on the environmental effects. With the rising costs of oil and their climate concerns the Ministry of Environment is determined to reduce energy consumption with any way possible (Ees.ae, 2013).
Solar energy reaching the earth’s surface is released back into space as infrared. CO2 and other Greenhouse gases in the atmosphere absorb some of that solar energy emitted from the earths’ surface and radiate some of it back to the earth’s surface. This greenhouse effect is causing the average global temperatures to rise, mostly in temperate and polar areas than in the tropics that’s why ice is starting to melt. So, the more the carbon dioxide in the air the greater the risk of increased global temperature.
How to reduce it (include UAE):
To reduce ones carbon footprint is to simply reduce the consumption of energy of each individual. Do your part by being aware of your actions and find out the factors that contribute to global warming and then proceed to help in protecting the environment. Measure and reduce your carbon footprint:
1. The largest portion of your carbon footprint is by driving your car. It’s around the size of your heel and arch put together. Lower your CO2 emissions by walking, riding public transportation or bicycle. Maintaining your vehicle keeps it running cleaner...

In today's world, where global warming is an issue, the way people choose to travel makes a difference. This paper contains the calculation of the Bay Area Rapid Transit (BART) system's carbon footprint and compares it to the carbon footprint of cars traveling the same distance. The results of this calculation will hopefully cause the average commuter...
Comparing Carbon Footprint of Reusable Nalgene Water Bottles to Single Use Bottled Water1602 words - 6 pages One of the greatest problems facing humanity is global climate change. Global climate change is the increase in average global temperature, caused by an increase in greenhouse gases. Greenhouse gases are the blanket of gases surrounding the earth that allow the world to be inhabitable. This layer of water vapor, carbon dioxide, methane, and other gases works in the same way that a greenhouse does, by trapping heat energy inside the...

Carbon Prices1629 words - 7 pages On February 8th, 2010 the Security Exchange Commission announced that carbon emissions had become an important factor in the decision making criteria for investors, regulators, government, and other stakeholders. Currently, companies are not required to release data that is not material to stakeholders, and as a result many companies choose not to disclose carbon emissions. This is because many issuers have determined that “climate change...
Global Warming is Causing Climate Change534 words - 2 pages Global warming is the increase in the earth’s atmospheric temperature. Naturally occurring gases such as carbon dioxide, methane, nitrous oxide, ozone and water vapor trap heat from the sun, preventing it from leaving the atmosphere. These naturally occurring gases along with human made hydro fluorocarbons (HFCs), per fluorocarbons (PFCs), and sulfur hexafluoride (SF6) are collectively known as greenhouse gases. This essay will explain why global...
1 Air travel is usually the largest component of the carbon footprint of frequent flyers. A single return flight from London to New York – including the complicated effects on the high atmosphere – contributes to almost a quarter of the average person’s annual emissions. The easiest way to make a big difference is to go by train or not take as many flights.
2 The second most important lifestyle change is to eat less meat, with particular emphasis on meals containing beef and lamb. Cows and sheep emit large quantities of methane, a powerful global warming gas. A vegan diet might make as much as a 20% difference to your overall carbon impact but simply cutting out beef will deliver a significant benefit on its own.

3 Home heating is next. Poorly insulated housing requires large quantities of energy to heat. If you have properly insulated the loft and filled the cavity wall, the most important action you can take is to draught-proof the house, something you can do yourself. Those with solid brick or stone walls will also benefit from adding insulation, but the financial benefits are unlikely to cover the cost of doing the work, over time.
4 Old gas and oil boilers can be hugely wasteful. Even if your current boiler is working well, it’s worth thinking about a replacement if it is more than 15 years old. Your fuel use may fall by a third or more, repaying the cost in lower fuel bills.
5 The distance you drive matters. Reducing the mileage of the average new car from 15,000 to 10,000 miles a year will save more than a tonne of CO2, about 15% of the average person’s footprint. If car travel is vital, think about leasing an electric vehicle when your existing car comes to the end of its life. A battery car will save you money on fuel, particularly if you drive tens of thousands of miles a year. Even though the electricity to charge your car will be partly generated in a gas or coal power station, electric vehicles are so much more efficient that total CO2 emissions will fall.
The innovators: greener home insulation to feather your nest
6 But bear in mind that the manufacture of an electric car may produce more emissions than the vehicle produces in its lifetime. Rather than buying a new electric vehicle, it may be better to keep your old car on the road by maintaining it properly and using it sparingly. The same is true for many other desirable items; the energy needed to make a new computer or phone is many times the amount used to power it over its lifetime. Apple says 80% of the carbon footprint of a new laptop comes from manufacturing and distribution, not use in the home.
7 Within the last couple of years, LEDs (light-emitting diodes) have become cheap and effective. If you have any energy-guzzling halogen lights in your house – many people have them in kitchens and bathrooms – it makes good financial and carbon sense to replace as many as possible with their LED equivalents. They should last at least 10 years, meaning you avoid the hassle of buying new halogen bulbs every few months. Not only will your CO2 footprint fall, but because LEDs are so efficient, you will also help reduce the need for national grids to turn on the most expensive and polluting power stations at peak demand times on winter evenings.
8 Home appliances. Frequent use of a tumble dryer will add to your energy bill to an extent that may surprise you. But when buying a new appliance, don’t assume you will benefit financially from buying the one with the lowest level of energy consumption. There’s often a surprising premium to really efficient fridges or washing machines.
9 Consume less. Simply buying less stuff is a good route to lower emissions. A suit made of wool may have a carbon impact equivalent to your home’s electricity use for a month. A single T-shirt may have caused emissions equal to two or three days’ typical power consumption. Buying fewer and better things has an important role to play.

10 The CO2 impact of goods and services is often strikingly different from what you’d expect. Mike Berners-Lee’s book How Bad Are Bananas? takes an entertaining and well-informed look at what really matters. Bananas, for example, are fine because they are shipped by sea. But organic asparagus flown in from Peru is much more of a problem.
11 Invest in your own sources of renewable energy. Putting solar panels on the roof still usually makes financial sense, even after most countries have ceased to subsidise installation. Or buy shares in new cooperatively owned wind, solar or hydroelectric plants that are looking for finance. The financial returns won’t be huge – perhaps 5% a year in the UK, for example – but the income is far better than leaving your money in a bank.
12 Buy from companies that support the switch to a low-carbon future. An increasing number of businesses are committed to 100% renewable energy. Unilever, the global consumer goods business, says its operations will be better than carbon-neutral by 2030. Those of us concerned about climate change should buy from businesses acting most aggressively to reduce their climate impact.

13 For a decade, investors ignored the movement that advocated the divestment of holdings in fossil fuel companies. Large fuel companies and electricity generation businesses were able to raise the many billions of new finance they needed. Now, by contrast, money managers are increasingly wary of backing the investment plans of oil companies and switching to renewable projects. And universities and activist investors around the world are selling their holdings in fossil fuels, making it more difficult for these companies to raise new money. Vocal support for those backing out of oil, gas and coal helps keep up the pressure.
14 Politicians tend to do what their electorates want. The last major UK government survey showed that 82% of people supported the use of solar power, with only 4% opposed. A similar survey in the US showed an even larger percentage in favour. The levels of support for onshore wind aren’t much lower, either in the US or the UK. We need to actively communicate these high levels of approval to our representatives and point out that fossil fuel use is far less politically popular.
15Buy gas and electricity from retailers who sell renewable power. This helps grow their businesses and improves their ability to provide cost-competitive fuels to us. Renewable natural gas is just coming on to the market in reasonable quantities in many countries and fossil-free electricity is widely available. Think about switching to a supplier that is working to provide 100% clean energy.
