"The solution to the climate challenge is decarbonization," he states. “气候挑战的解决方案是脱碳”，他说。

A massive decarbonisation of the energy sector is necessary.

the process of removing carbon or material containing carbon from a substance or from an object, such as an engine

There is evidence of early steel production techniques utlizing partial decarbonization.

Engine decarbonization can be a chemical or mechanical process in which carbon deposits on the cylinder head and pistons are removed to ensure better functioning of the engine. 发动机除碳可以是一个化学或机械过程，在这个过程中，气缸头和活塞上的碳沉积物被去除，以确保发动机更好地运作。
