But carbon dioxide is carbon dioxide.

1 GT (or gigatonne) CO2 equivalent means 1,000 million of tonnes of CO2.

MT (or mega tonne) of CO2 equivalent means 1,000,000 tonnes of CO2.

3 The anthropogenically produced greenhouse gases include carbon dioxide (CO2) methane (CH4) nitrous oxide (N2O) hydrofluorocarbons (HFCs) perfluorocarbons (PFCs) and sulphur hexafluoride (SF6).

Trees give off oxygen and absorb carbon dioxide.

Areca palm is a plant which removes CO2 and converts it into oxygen.

One car emits four tons.

Cars and trucks add up to about 25 percent of the world's CO2 emissions.

Now, as we breathe, we produce carbon dioxide, and that carbon dioxide needs to be scrubbed out of the system.

Here, we've got a protocell to extract carbon dioxide out of the atmosphere and turn it into carbonate.

We see it that way. Plants are busy making long chains of starches and glucose, right, out of CO2. He's found a way he's found a catalyst and he's found a way to take CO2 and make it into polycarbonates. Biodegradable plastics out of CO2 how plant like.

This is mainly caused by a steep decrease in the emissions of CFCs, primarily from refrigeration plants (from 1.6 Gt CO2 eq to 0.3 Gt CO2 eq), responding to the requirements of the Montreal Protocol.

While the carbon dioxide, vast quantities of it, gigatons, goes into the atmosphere where we can't get it back yet and where it is causing the problems that we're most concerned about.

Which was emitting the most CO2?

Hypothetically, switching off the lights for an hour would cut CO2 emissions from power plants around the world. But, even if everyone in the entire world cut all residential lighting, and this translated entirely into CO2 reduction, it would be the equivalent of China pausing its CO2 emissions for less than four minutes.

I came here to speak about ecology, and I emitted as much CO2 as a Frenchman in one year.

Use of oil with tetra ethyl lead causes much pollution, with lead containing carbon monoxide, nitrogen oxide and policyclic nitro hydride.

CO2 as a building block.

The use of wood products in place of materials that are associated with the release of large volumes of carbon dioxide could lead to significant net reductions in carbon dioxide emissions.

Oxalic acid is two carbon dioxide molecules joined together.

Well, it's not the lava that kills anything, it's the carbon dioxide that comes out with it.

1 The World Health Organization recognizes six main types of air pollutants carbon monoxide, nitrogen dioxide, particulate matter, sulphur dioxide, tropospheric ozone and suspended particulate matter.

Maybe they could extract carbon dioxide.

An accretion itself is a huge sink of carbon dioxide.

We can't see CO2 we depend on scientific measurements for it and we see the beginning results of having too much of it but we can see pre CO2 now floating on the waters and contaminating the beaches in the Gulf.

Carbon dioxide level has gone up and up and up.

Here's another big idea CO2 as a feedstock.

You know, breathing high concentrations here of sulfur dioxide, carbon dioxide and methane gas, in unequal quantities 19 years of this.

Instead of cement usually emits a ton of CO2 for every ton of cement.

We exhale carbon dioxide, so does mycelium.

And it puts 18 thousand tons of carbon dioxide in the air.

Most CO2 emissions result from the burning of fossil fuels coal, oil, and natural gas for energy, global consumption of which is rising as the world economy grows. As a result, we are on a path to very dangerous levels of CO2 in the atmosphere.

And, the other component on a breathing loop is the carbon dioxide absorbent canister.

Climate change deniers like to use this fact to confuse and trick the public by saying, Look, the temperature causes CO2 to change, not vice versa.

Organisms don't think of CO2 as a poison.

It's not only carbon dioxide that has this hockey stick pattern of accelerated change.

It's got the huge advantage that it does not create carbon pollution.

Number one temperature and carbon dioxide in the atmosphere go up and down basically in sync.

Carbon dioxide, a little bit of sunlight, you end up with a lipid that is highly refined.

The mycelium is producing enzymes peroxidases that break carbon hydrogen bonds.

And we knew that we were losing CO2.

Yeast is eating sugar and turning it into carbon dioxide and alcohol.
