The term "carbon footprint" is a convenient way to measure a global warming impact, and is based on CO2 equivalents, but carbon does not actually have to be involved.
For generating electricity, for example, a technology can be rated in grams of CO2 equivalent per kilowatt hour of electricity produced (gCO2e/kWh).
For example, new solar photovoltaic cells require a lot of heat to manufacture, as did the old ones. The thing that made them different in manufacture was that the old cells were made using a gas called nitrogen trifluoride or NFl3 (note, there is no carbon in this stuff). Some of this gas inevitably escaped into the environment, even though it was trapped as well as possible, and since it is about 17000 times as powerful as a global warming gas as CO2, it had an effect on the carbon footprints of the cells. Old solar photovoltaic cells were rated at about 105 gCO2e/kWh. If there had been no other change, the new cells would be about 60 to 80 gCO2e/kWh. It happens that there were other improvements in manufacture, and the cell efficiencies increased, so the new cells are about 35-40 gCO2e/kWh.

What are the gases from carbon footprints possibly causing?
Greenhouse gasses, the gasses that are Sid to have carbon footprints, cause global warming.
Are carbon footprints the same size around the world?
No. A carbon footprint is highly correlated with per capita usage of fossil fuel. The United States has one of the largest carbon footprints. Many African nations have very tiny carbon footprints.
How do you make carbon footprints?
us
Where do you find carbon footprints?
after you step on the ground with a carbon foot.
Are footprints the same size around the world?
No. A carbon footprint is highly correlated with per capita usage of fossil fuel. The United States has one of the largest carbon footprints. Many African nations have very tiny carbon footprints.
How can your family reduce its carbon footprints?
There are many ways you and your family could reduce it's carbon footprints. You could walk not drive for example.
How leaving carbon footprints?
By following it in its footsteps.
What is the carbon footprints?
This is the total emissions of carbon (from CO2 and CH4), expressed in tons, for a country in one year.
What you can say about people from footprints?
It is important to reduce the value of carbon footprint.
Does depletion of the ozone layer carbon dioxide?
Depletion of ozone causes global warming. It increases carbon footprints.
How do carbon footprints affect people?
The earth was created for all the creatures that inhabit it! All of God's creation breathe Oxygen and exhale Carbon Dioxide. Carbon footprints affects only the people who choose to be affected. All Green plants take in Carbon Dioxide and convert it in to Oxygen When ocean water evaporates, what happens to the Oxygen in H2O?
What steps are people taking to reduce their carbon footprints and global warming?
by burning fossil fuels
