Decarbonization refers to the process of reducing carbon intensity or CO2 emission in the atmosphere and lowering the level of greenhouse gas emissions and acid rain produced by the burning of fossil fuels, through the use of other resources that use low consumption of CO2 or it refer to the actual removing carbon buildup and carbon deposits from internal combustion engines. While both of these processes involve removing carbon, but they do it in very different ways.
To achieve deep decarbonization, a lower CO2 output can be achieved by eliminating technologies and energy sources that cause a lot of CO2 emissions, replacing them with low-carbon and zero-carbon alternatives, and by reducing energy requirements. At the same time, emissions can also be offset by carbon sequestration or storage.( read more here)
