carbon dioxide
A colorless and odorless gas (chemical formula CO₂) that is produced during the combustion of carbon-containing materials and during respiration. It is a natural component of air and an important greenhouse gas.
Der Ausstoß von Kohlendioxid muss reduziert werden, um den Klimawandel zu verlangsamen.
Carbon dioxide emissions must be reduced in order to slow climate change.
The word is made up of 'Kohle' (coal/carbon) and 'Dioxid' (dioxide). 'Kohle' refers to 'Kohlenstoff' (carbon), the main component. 'Dioxid' is an international technical term for a compound with two oxygen atoms.
Pflanzen nehmen Kohlendioxid aus der Luft auf.
Plants absorb carbon dioxide from the air.
In the context of climate change, 'Kohlendioxid' (carbon dioxide) is often combined with certain verbs and nouns, for example 'der Ausstoß von Kohlendioxid' (carbon dioxide emissions), 'Kohlendioxid-Emissionen' (carbon dioxide emissions), or 'Kohlendioxid reduzieren/vermeiden' (to reduce/avoid carbon dioxide).
Viele Länder haben sich verpflichtet, ihren Kohlendioxid-Ausstoß zu reduzieren.
Many countries have committed to reducing their carbon dioxide emissions.
In scientific texts, but also in the news, the chemical formula 'CO₂' is often used instead of the full word 'Kohlendioxid' (carbon dioxide). Both terms are interchangeable.
Der CO₂-Gehalt in der Atmosphäre steigt weiter an.
The CO₂ level in the atmosphere continues to rise.
carbonation / carbonic acid
Kohlendioxid and Kohlensäure are related, but they are not chemically the same. Kohlendioxid is the gas CO₂, while Kohlensäure forms when this gas dissolves in water. When referring precisely to the dissolved substance and its reaction with water, Kohlensäure is the appropriate term.
Das Getränk enthält gelöstes Kohlendioxid, das beim Öffnen entweicht.
The drink contains dissolved carbon dioxide, which escapes when it is opened.
Durch das gelöste Kohlendioxid bildet sich im Wasser Kohlensäure.
The dissolved carbon dioxide forms carbonic acid in the water.
