The construction industry uses large quantities of concrete, which is manufactured from cement. Cement manufacture is a significant source of carbon dioxide emissions.
Emission.
The best way of reducing emission of carbon dioxide is to use carbon-free or reduced-carbon materials

In some cases the emission of a large amount of carbon dioxide can displace oxygen from the air. As a result, people and caught in the gas cloud can asphyxiate.

Euro II norms suggest that the aromatic hydrocarbons are to be contained at 42 %
Emission.
Negative carbon dioxide emission is the opposite of carbon dioxide. The formula for carbon dioxide is CO2.

A zero-emission vehicle is a vehicle which produces only carbon dioxide and water as its emissions and therefore does not pollute the air.
