greenhouse gas
A gas in the atmosphere that contributes to global warming by absorbing heat radiation and thus intensifying the greenhouse effect. The most important greenhouse gases include carbon dioxide, methane, and nitrous oxide.
Die Reduzierung von Treibhausgasen ist ein zentrales Ziel der internationalen Klimapolitik.
The reduction of greenhouse gases is a central goal of international climate policy.
The word is composed of 'Treibhaus' (greenhouse) and 'Gas' (gas). A 'Treibhaus' (greenhouse) is a glass house that stores heat so that plants can grow. A 'Treibhausgas' (greenhouse gas) works figuratively like such a house for the whole Earth and contributes to warming.
Kohlendioxid ist das bekannteste Treibhausgas.
Carbon dioxide is the best-known greenhouse gas.
In connection with greenhouse gases, the verbs 'ausstoßen' (to emit), 'emittieren' (to emit), 'reduzieren' (to reduce), and 'vermeiden' (to avoid) are often used. These describe how the gases are handled in the context of climate protection.
Viele Länder haben sich verpflichtet, weniger Treibhausgase auszustoßen.
Many countries have committed to emitting fewer greenhouse gases.
Common and fixed formulations are 'der Ausstoß von Treibhausgasen' (the emission of greenhouse gases) or 'die Emissionen von Treibhausgasen' (greenhouse gas emissions). The word is very often used in the plural because people usually talk about different gases.
Der Ausstoß von Treibhausgasen durch die Industrie ist ein großes Problem.
The emission of greenhouse gases by industry is a major problem.
emission
'Emission' and 'Treibhausgas' both often appear in texts about climate and the environment. But they do not mean the same thing. A 'Treibhausgas' is a specific gas, for example carbon dioxide or methane, that contributes to the warming of the Earth. 'Emission' means the release of such substances into the environment. The words can be confused because people often talk about 'Emissionen von Treibhausgasen' (emissions of greenhouse gases). The simple difference is: the greenhouse gas is the substance; the emission is the release or the amount released.
Methan ist ein starkes Treibhausgas.
Methane is a strong greenhouse gas.
Durch weniger Flugreisen sinkt die Emission von Kohlendioxid.
With fewer air trips, the emission of carbon dioxide decreases.
