What country has the smallest carbon footprint?

Kiribati, a small island nation in the Pacific Ocean, has the smallest carbon footprint. It is particularly vulnerable to sea-level rise from global warming, and its President signed the Bandos Island declaration on 10 November 2009. This was a promise by Kiribati and nine other countries to show moral leadership and start greening their economies by voluntarily committing to carbon neutrality.

How does cutting down trees affect us and our environment?

Trees give out oxygen. even because of them we have the rains. in short they maintain the ecological balance. If we would cut trees what is going to happen is that population won't stop growing but oxygen in the atmosphere will reduce. Another effect can be scarcity of food. and many other problems are attached to it such as less of rains will result in less water for irrigation. Less water for irrigation would result in less harvest which would again lead to less food and if this continues to happen for a long period of time then it might lead to famine type situations.

Trees have to breathe to live, same as us and every living thing on the planet. They breathe in carbon dioxide and breathe out oxygen. We breathe out carbon dioxide and breathe in oxygen. We've evolved around trees; they are the main things that give off oxygen. Without trees, we're not here. Cutting down trees takes away that oxygen. If you cut down a tree but plant two new ones that is fine. Trees are living things too.

The most important is, tree are necessary for rain. trees creates cold and humid atmosphere required for rain.

Second, when it rains, trees hold the water and and does not allow to pass over soil which avoids floods.

Third, they provide food to all of livings.

If we continue to cut tree at larger extent then, it will definitely affect the rainfall and also will create a unstable atmosphere which will lend to destruction on/of earth.

When we cut down trees, we are taking a home away from animals.

We loosen the ground which mostly causes landslides.

Trees cause shade and without that shade the ground dries up faster and there is not as much nutrients.

How can you reduce energy consumption?

  • Wash a full load (clothes or dishwasher) and pretreat or soak before hand so you can wash on cold,
  • Use the sun and the wind to dry your clothes. If that's not possible, don't dry clothes all the way, dry mostly and hang for the remainder of drying,
  • Get a more efficient washer/dryer/dishwasher/water-heater/heat pump/fridge.
  • Make certain all your windows and doors are sealed and use double or triple glazed windows.
  • Reduce your use of air-conditioning. Wear warmer or cooler clothes around the house.
  • If you use window A/C remove the units in the winter or cover them to prevent losing warmer air, also be sure that your chimney is closed off when not in use. Be sure to change your air filter every month.
  • Switch to lower wattage or more efficient lights,
  • Don't leave computers/TVs/stereos/lights or other energy users on when not using them. Stand-by, or vampire, energy can add 10% to your bill. If you love background noise get a radio. :)
  • Sweep hard floors instead of vacuuming and make a no shoes rule to cut down on vacuuming.
  • Keep your fridge well organised so you can see what's in there at first glance to cut down on time spent "rummaging,"
  • Cool foods before refrigerating (do not leave out for more than 2hrs after cooking and cover while out) and refrigerate in smaller containers.
  • If moving or building a home is an option consider a more energy efficient home, one that uses gas, solar or alternative energy source or check out the Monolithic Dome Institute for the safest, most efficient home you can build!
  • Each house will have different opportunities to optimize energy efficiency. In my home, a quick tip that helped a lot was to get insulated curtains to cover large window areas. The house is over 30 years old and needs to be upgraded with better windows, but in the mean time, a cheaper way to save on our heating bill has been to buy and put up insulated curtains.
  • Start by unplugging devices you don't use. Usually something like a TV with an "instant on" function will use energy 24/7. Turn off your computers and monitors at night.
  • If you have electric hot water, you can wrap your heater with a sweater avail from home supply stores.
  • You can take shorter showers.
  • You can wash clothes in warm instead of hot.
  • You can hand wash dishes instead of using a dishwasher.
  • If you have an electric dryer, don't over stuff it. Clothes dry faster when packed loosely.
  • Use energy efficient bulbs, and turn off lights when not needed, including that front porch light.
  • Double gazing can help save energy bills also cavity wall insulation.
  • You can reduce energy consumption by unplugging electronics when not in use, taking shorter and colder showers, reducing your home thermostat in the winter, and using less air conditioning in the summer.
  • By turning off devices you don't need (for example, turn off the lights when you are the last to leave a room)
  • By purchasing devices that are more energy-efficient (for example, energy-efficient light bulbs).
  • Reflective foil insulation products can reduce attic temperatures by up to 30 degrees when installed to the underside of roof rafters. Lowering attic temperatures provides a significant benefit by reducing air conditional loads and energy usage.

How do boats affect the environment?

The noise and motorized functions of boats can disrupt wildlife and the environment, and the waste generated by boats can also be harmful to the environment. Boat propellers can also kill animals in ocean water.

Another perspective: More, now than ever, the public eye is focused in on the environment. With this call to action, cruise lines have stepped up to the plate to care for the environment in ways you may not expect.

A world-wide agreement in respect to protecting the oceans and environment called MARPOL was passed defining the standards of environmental protection. Some of these requirements include:

Requirements for what can go overboard (virtually nothing except clean treated water and 'pulped' sorted food waste to feed the ecosystems.

Requirements for containing any spills and cleanup procedures.

What can and can't be burned on board. Currently some plastics and most paper and cardboard are incinerated on board. Other materials such as glass, metals, heavy plastics, medical waste, sludge (oil and black water) are offloaded and recycled or processed by shore-side vendors.

As far as fuel is concerned, it is necessary for large ships to keep engines on at all times, even in port, to keep lights, air, electricity, refrigeration etc. going. However, ships are constantly upgrading fuel sources and fine-tuning engines to ensure the cleanest possible burn. Furthermore, the future of cruise ship ports may include an opportunity to connect to shoreside power, which would allow them to power down onboard engines and reduce emissions even further.

All cruise lines understand and respect the environment. There's nothing special about taking a cruise if the oceans are filled with waste and pollution all of the time, right?

How does EZ pass save money and time and environment?

In saving money:

I think you get a discounted rate/ticket when you use it, rather then the cash fare

Time:

Simply cruise through the toll booth at a slow speed, instead of stopping, waiting in line, getting ticket, paying ticket etc.

Environment:

Cruising through the toll booths uses less fuel then having to come to a full 'dead' stop and then starting up again, along with not waiting in line burning fuel

What is unstable equilibrium?

When a body is in unstable equilibrium, on slight displacement the centre of gravity of the body will be lowered. If the line of action of its weight lies outside the base area of the body, it will topple.

Objects that have high centres of gravity, a small base area, or are top-heavy are more likely to be in unstable equilibrium. Stability can be increased by lowering the centre of gravity and/or increasing the area and/or the weight of the base.

How can you reduce your carbon footprint?

There are too many ways to reduce your carbon footprint to list here.

However, here are some of the main ones:

  • Use less electricity, or get a renewable energy source (such as wind or solar power).
  • Reduce, reuse, and recycle any household garbage as much as you can.
  • Compost as much kitchen waste and paper waste as you can.
  • Buying local products, such as foods (the further a product is shipped, the more fuel is wasted on transporting it).
  • Using public transportation, carpooling, or, ideally, cycling or walking to go from place to place.
  • If you want to make your household even more eco-friendly, consider:
  • Reducing your water usage
  • Buying certified organic food and certified organic cotton clothing
  • Using biodegradable soaps and cleaning products.

Hope this can help you to help the Earth!

  1. Try to use public transport when possible, or car share. Drive as little as possible - walk or cycle when you can.
  2. Turn your water heating and central heating down slightly when it isn't too cold
  3. Don't leave any lights etc. on when you don't need them
  4. Try not to waste water so have a short shower rather than having a bath.
  5. don't throw away so much food, stick it in a container and use it for a day where you can't be bothered making dinner.
  6. recycle, if you recycle it will be cutting down on the amount of plastic that goes into the world and when you are finished with something recyclable make sure you check on the side to see if it is recyclable
  7. Don't leave appliances on stand-by - always turn them off and if possible, unplug them when not in use.
  8. Use as few resources as possible.
  9. Try to make make sure that your home and work place are making efficient use of energy - insulate, use low-energy LED lights, update old equipment (e.g. boilers, heating, air-conditioning) to newer more energy efficient models. This will also save money in the long term as it will keep utility bills down.
  10. Re-use and recycle whenever possible, and when you buy new products, research the resources that went into making and transporting them, and let that inform your choices. When you have to buy new things, buy local.

- Go Green: use as many green solutions as you can, from buying a hybrid car to using solar panels.

- Teleworking: use conference calls so that you don' t need to travel so much to meet up with your team.

there are LOTS of ways to decrease it:

  • take shorter showers
  • walk instead of driving
  • don't waste paper
  • don't waste electricity (leaving lights on)
  • use environmentally friendly resources (solar panels, recycled materials, etc.)
  • live in a small house with small amount of people

you probably get the point!! just anything that's good for the environment!!

heat the house less in the winter.

There are lots of ways to reduce; you can drive less , ride your bike more often and walk instead. You can plant flowers and trees. You can also use less electricity and recycle etc.

People can reduce their carbon footprints by driving less, taking more public transport, going to places by walking or cycling, reducing home heating and electricity use, and choosing energy efficient appliances.

What is an ecological footprint?

An ecological footprint measures how much of the planet's resources you use, and converts this to the amount of land needed to provide the resources and assimilate your waste. It is measured in global hectares (a hectare is about the size of a soccer field). It includes:

* The amount of building materials you use in your home and workplace * The amount of water you use in your home, workplace and garden

* The fossil fuels (oil, coal, wood and natural gas) needed

* to provide the power to run your home and workplace

* to bring your food from all over the world

* to power your vehicles and transport * to carry away and dispose of your waste.

A recent study (October 2008) ranks the top ten countries with the highest ecological footprint per head as:

# United Arab Emirates # United States # Kuwait # Denmark # Australia # New Zealand # Canada # Norway # Estonia # Ireland.
It is what you leave behind such as a foot print at the park. Only in this place the foot print is the resources you use up during a life time.

What is the carbon footprint of a photovoltaic cell?

One current estimate is 35 to 58 g CO2e/kWh (this is explained in the last paragraph of this answer). Another estimate at the link cited below says 23.6 g CO2e/kWh for thin film CdTe cells. This compares to 25 to 80 for biomass, 3 to 10 for hydro, and about 5 to 15 for wind. I have often seen huge differences in estimates of the carbon footprint of nuclear power, ranging from 2 to 288 g CO2e/kWh. It seems that the actual number is probably more than 66 g CO2e/kWh, and very possibly more than 90.

PV technology is changing rapidly, both for the actual PV and for the manufacture of PVs. The above estimate is not for thin-film PVs, and these promise to have a much smaller carbon footprint. Also, the estimate given is for PVs that are 5% efficient in producing power, and increases in power output will decrease the carbon footprint. Current PVs are mostly considerably more efficient, and at 7.5% efficiency, the carbon footprint is cut to 23 to 39 g CO2e/kWh. New, gadolinium-based PV technologies are said to be as high as 40% efficient, but I have not seen any estimates of their carbon footprints and could not guess, because I do not know how they are manufactured.

By the way, thermal solar power, such as is used in solar hot water, is about 60 to 65% efficient, and has much lower cost, in terms of global warming gasses, than PVs. It has a carbon footprint that might even be smaller than wind's.

The carbon footprint is calculated in grams of CO2 equivalent per kilowatt hour (g CO2e/kWh). Properly, this includes all phases of manufacture of equipment and fuel, transportation, installation, operation, and disposal. Calculations are often deceptive because steps are left out for some technologies, notably the decommissioning and disposal steps are often left out in calculation of carbon footprints for nuclear power. The "equivalent" part happens because of global warming gasses other than CO2. For example, the nitrogen trifluoried used in manufacture of photovoltaic panels is about 17,000 times as powerful as CO2 for global warming, so an estimate of the amount leaking into the environment from the manufacturing process has to be included.

What is the definition of carbon footprint?

An ecological or carbon footprint measures how much of the planet's resources you use, and converts this to the amount of land needed to provide the resources and assimilate your waste. It is measured in global hectares (a hectare is about the size of a soccer field). It includes:

  • The amount of building materials you use in your home and workplace

  • to provide the power to run your home and workplace
  • to bring your food from all over the world
  • to power your vehicles and transport
  • to carry away and dispose of your waste.

A carbon footprint is the amount of carbon dioxide that one person creates and uses with all the things he or she does.

It is how much damage on the environment that something has. The carbon footprint for a bottle of water would add up the negative environmental impact of manufacturing plastic bottles and truck emissions for delivering the water. Your house would have a carbon footprint.

There are websites that help you determine carbon footprints

A person's carbon footprint is defined by looking at how much of what they do in their lives contributes even a small amount to global warming. Such things include recycling, driving where it is possible to walk and not switching off house lights. We can reduce our carbon footprint by being more ecologically friendly.

Carbon footprint is a measure of the impact our activities have on the environment, and in particular climate change. It relates to the amount of greenhouse gases produced in our day-to-day lives through burning fossil fuels for electricity, heating and transportation, food etc.

What is the carbon footprint of geothermal power?

Geothermal power production has a carbon footprint associated with the construction and operation of the plant, but also because global warming gasses leak from the wells dug for heat extraction.

The DOE provides information on carbon footprints and estimates geothermal power at 0.18 pounds or 84 grams CO2 equivalent per kilowatt hour (g CO2e/kWh) produced. The paper having this information, "Production of Greenhouse Gases from Geothermal Power Plants," by K. K. Bloomfield and J. N. Moore, does say that at least one plant is operating at about half this amount (a link to this paper is below).

By way of comparison, the same paper provides the following:

  • coal 970 g CO2e/kWh
  • oil 710 g CO2e/kWh
  • Natural gas 470 g CO2e/kWh
  • geothermal 82 g CO2e/kWh

Though not included in the paper, typical estimates for wind and hydro are 12 to 20 g CO2e/kWh, solar photovoltaics 23 to 40 g CO2e/kWh, and nuclear 66 to 150 g CO2e/kWh.

How do factories contribute to major problems such as pollution and global warming?

Factory pollution is one of the minor contributors of global warming; however it can be stopped before it gets any worst than it already is.

Industry pollution mostly comes from the factories that are over ten years old . If we make new factories that don't cause as much pollution and knock down the older factories it will lower the percent of pollution that factories give off. Even if that doesn't work it is still possible to lower the percent of pollution factories give off by using an alternative source of energy instead of burning fossil fuels in factories. This will slow down global warming. If the normal everyday people just don't use as much energy we won't have to burn as much fossil fuel .

Global warming is the effect of 200 years of burning fossil fuels, such as coal and oil, deforestation and other natural disasters. When the sun's heat rays come into the earth's atmosphere the greenhouse gases trap most of the heat and that heat continues to build up, and heat the earth more and more every year. Doing this causes the heat-trapping "greenhouse gases" to increase significantly in the atmosphere every year if not stopped. These gases prevent heat from escaping to space.

One major cause of global warming is industry pollution. Factory pollution is over 40% of the pollution that causes global warming according to some sources, others disagree. One of the diseases that it causes is asthma. More than twenty million people a year have asthma attacks and over 9,000 children in the United States die a year from asthma attacks. Other diseases are heart and lung diseases, and respiratory allergies. The World Health Organization estimates that in all 4.6 million people die each year from causes that are directly from air pollution. According to Scorecard, over 20,000 factories in the United States produce over 4 billion pounds of toxic chemicals that could leak into the environment. Some of these gases contain items that might cause a fire and that well cause global warming, because of the carbon coming from the fire.

The effect of global warming will make the sea level rise nine to eighty-eight centimeters, because of the melting glaciers. This doesn't seem like a lot now, but in a few years when the sea level rises more it will cause more floods because of the water cycle. The water cycle is where the water comes from, the ocean comes up into the clouds and comes down as rain. Then most of the water goes back into the ocean and it starts all over again. With more water there will be more rain and more floods. Global warming is basically another word to explain the theory, that all around the world the temperature of the earth is increasing.

This is all the information needed to know about industrial pollution and how to stop it. Global warming is just another term to name the theory that the temperature all around the world is increasing, but there are still ways to stop it if people take part in helping clean up the mess made on earth.

Addenda

Though factories do contribute to the addition of pollutants and 'Greenhouse gasses', by far, the greatest amount is from natural processes.

Nor can our factories be 'stopped'. Unless you wish to disassemble the entire technology on which our civilization is based.

Knocking down and building new factories would add to the problem and any benefits from cleaner use would not be seen for decades.

Giving simplistic answers addressing such problems adds to the problems, as does disseminating such information.

There are almost 7,000,000,000 people in the world, many starving or on subsistence diets. To do away with the very infrastructure that is presently keeping these people alive is not a solution.

What are the disadvantages of using oil as an energy resource?

Some disadvantages of oil are that -

* it is non-renewable and fast depleting; * burning it releases carbon dioxide, a powerful greenhouse gas, that had been stored in the earth for millions of years

* it leaves behind harmful by-products upon combustion, thereby causing a lot of pollution; * mining of oil leads to irreversible damage to the adjoining environment; * Oil spills as well as evaporation and fumes pollute the environment; * Used oil is difficult to recycle. * The price of oil is rising, especially if the real cost of its carbon is included. * Burning it produces carbon dioxide, a major cause of global warming.

=== === The basic problem with coal and other carbon based fuels in not really that they release carbon-- it is that the carbon they release is not then quickly and efficiently absorbed by some other process, eliminating it from the atmosphere. We are taking unimaginably huge quantities of carbon, stored away for eons, and pouring it into the air. It will remain there for eons more, until the earth goes through more of its own balancing cycles. http://sciencedata.blogspot.com/ The disadvantages of oil energy is that it produces carbon dioxide when burned, limited supply of oil, can be environmentally damaging, transportation of oil caused damage to animals. It can have oil spills which destroys ecosystems, kills marine life, isn't good for the environment. It also produces carbon dioxide when oil is being burnt. Also, it is higly toxic. Crude oil is a finite natural resource. It exists as a mixture of hydrocarbons with traces of sulfur and other compounds. In order for useful products to be separated from crude oil, it must be treated with "thermal cracking," an energy-intensive process that separates and reforms different hydrocarbons based on their boiling point.

So, crude oil will run out, and you have to invest energy in order to get usable energy from it. The massive amounts of CO2 released when oil is combusted alter the composition of the earth's atmosphere. Burning oil creates greenhouse gases as a by-product, which can contribute to the effect of global warming. Also, incomplete combustion of oil can form carbon monoxide, which if allowed to build up in a confined area can prove to be faithful. The insecurity of oil in the global financial market is a distinct disadvantage on reliance on oil also.
Most importantly, it is a limited resource, which some day will be gone. We are exploring in deeper waters and finding new ways to extract oil, but this doesn't change the fact that the global supply of crude oil is reduced with production. The new sources of petroleum will be much more expensive. As with any scarce resource, the price will go up and this in turn can make gasoline more expensive. The future increase in the cost of petroleum will make many petrochemicals go up and increase the transportation costs. Suggest you do a google search on petrochemicals to get an idea of how many goods will be affected. The consumption of crude oil as fuel (diesel, gasoline) is a major environmental problem, as combustion causes carbon monoxide and carbon dioxide emissions, and contributes to global warming. Also, the added pollution from the combustion of oil (and coal) contributes to acid rain. An area that is particularly controversial is the degree to which the exploration, extraction and transport of crude oil causes environmental damage. There has been a trend to fewer tanker oil spills, but the ones that have occurred, such as Valdez oil spill caused severe damage. There's controversy over potential for environmental damage from new leases in the Gulf of Mexico, near Florida coast line because of concern of spills and the north slope of Alaska (search for ANWR) because of concern of the effect on wildlife. Drilling and producing operations in the Amazon basin can cause environmental damage, because an oily water is frequently produced with the oil, and can cause damage if not properly treated. (There is a long standing claim of environmental damage from Texaco's operation in Ecuador)
