What is the carbon footprint of an item of airmail from Miami to the UK?
The carbon footprint of airmail from Miami to the UK can vary depending on factors like aircraft type, distance, and package weight. On average, a rough estimate could be around 0.5-1 kg of CO2 emissions per kg of airmail transported this distance.
How does a carbon footprint harm the planet?
Things with large carbon footprints do damage to the earth by releasing large amounts of carbon. Things with small carbon footprints do little damage.A carbon footprint is just a number, telling you how much carbon is produced in the making, producing, transporting and using of a certain thing. This thing could be a car, or a bottle of beer, or a tin of vegetables, or your house, or even you.For example, the carbon footprint of a tin of vegetables that was produced on the other side of the world would consider the collection, transport, cooking and canning of the crop. It would then factor in the cost of transportation half way round the world, by ship, air, truck and perhaps your own vehicle. Compare this to vegetables grown in your own garden, or at least in your own local area.So an item with a large carbon footprint releases more carbon into the atmosphere, adding to the greenhouse gases already there, and contributing to global warming, much more than an item with a small carbon footprint.
How can your family reduce its carbon footprints?
To reduce your family's carbon footprint, you can try reducing electricity consumption by using energy-efficient appliances and lighting, cutting down on meat consumption, using public transportation, biking, or walking instead of driving, and by incorporating more sustainable practices into your everyday life such as recycling and composting.
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.
How do you think you could contribute to the preservation of our planet?
I could contribute by reducing my carbon footprint through practices like recycling, using less plastic, and conserving energy. Additionally, I could support environmental organizations and advocate for policies that promote sustainability and protect natural resources. Lastly, spreading awareness and educating others about the importance of environmental conservation would also be important.
What is a carbon footprint-?
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 etc.(The amount of greenhouse gas released by an organism.)The carbon footprint is a measurement of all greenhouse gases we individually produce and has units of tonnes (or kg) of carbon dioxide equivalent.Carbon footprints:A carbon footprint is the amount of carbon dioxide that one person or one activity creates. It is suggested as a measure of 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. Some activities have an indirect carbon footprint by removing "carbon sinks", i.e. removing things that would remove carbon dioxide. The most obvious ones are the massive deforestation going on in many tropical areas through slash-and-burn agriculture, mining, etc.Reducing carbon footprints: You could lower the carbon footprint of your house by doing things like using CFL lighting and energy efficient appliances, and adding insulation. There are websites that help you determine carbon footprints. It is also possible to reduce net carbon footprint by adding plants which absorb carbon dioxide and release oxygen to the atmosphere.
What factor is used to measure carbon footprint?
Carbon footprints are measured in terms of their ability to trap heat in the atmosphere, as related to carbon dioxide. The unit of measurement is grams equivalent of carbon dioxide per kilowatt hour (gCO2e/kWh). For example nitrogen trifluoried is 17000 times as able to trap heat in the atmosphere as carbon dioxide, so a gram of nitrogen trifluoride has a carbon footprint of 17000 gCO2e/kWh.Or you could use a carbon calculator.

What does carbonfootprint mean?
A carbon footprint is a "measurement" of carbon emissions (and other greenhouse gases) created by a subject. The term usually refers to a business, but it could also be assigned to an individual, a product, a country, or an event.
What type of measurements are used to calculate your footprint?
In discussing environmental issues "footprint" is the impact you have on the world or the ecosystem.The calculation of footprint is generally very poorly done due to the complexity of the impacts involved, both gives and takes. As an example "carbon footprint" is generally considered to be the amount of greenhouse gases equivalent expressed as carbon dioxide that an individual releases - this could include direct fuel consumption, power consumed to manufacture household goods, methane released from cattle used in food production, reduction in carbon sinks through forestry products consumption and so on on the impact side and the impacts of recycling, reduced fuel consumption and birth control on the positive sde.There are several non-renewable resources that cpuld be treated in the same way - you could have a "Petroleum footprint" or a "Helium footprint" as well.

How do you use the word footprint in a sentence?
A sentence could be : A footprint is a mark made by a shoe or your own foot.
How is ethanol and oil the same?
Ethanol and oil for fuel are both rather simple liquid hydrocarbons. Both can be used as fuel for internal combustion engines, turbines, and heating units. In many cases, equipment can be designed or retrofitted to burn either. Both burn to form carbon dioxide and water, but their carbon footprints are different. Petroleum is a fossil fuel, but ethanol is not. Petroleum predictably has a pretty specific carbon footprint, but the carbon footprint of ethanol varies according to how it is produced and is somewhat controversial. The production of ethanol could produce very little global warming gas, but it could also produce a lot.
Are space suits aerodynamic?
Not by minimal standards, however MIT has recently developed an aerodynamic space suit that could later be applied during space travel.

What are things you could do to help the envirentment?
To help the environment, you can reduce waste by recycling and composting, which minimizes landfill contributions. Using public transportation, biking, or walking instead of driving can lower carbon emissions. Additionally, conserving water and energy at home by using efficient appliances and turning off lights when not in use can significantly reduce your environmental footprint. Supporting local and sustainable products also promotes eco-friendly practices and reduces the carbon footprint associated with transportation.
How does the amount of carbon dioxide in the atmosphere affect life?
Carbon absorbs reactant chemicals. In some cases of poisonings eating a bunch of charcoal is a temporary measure in containing the poison before the stomach can be pumped. Otherwise pure carbon is pretty nonreactive.
