“…First, to reduce GHG emissions, the relevant government departments should set stricter fuel economy standards [54] to promote the development of biofuel technology [55,56] and tax fuel to encourage technological innovation. As the transport sector with the greatest impact on CO 2 emissions, air transport must continue to develop technologies such as electric aircraft to increase the electrification rate on the one hand and to vigorously develop hydrogen-driven and biofuel technologies on the other hand [36]. The water transport sector, which has the largest volume of freight, needs to continue to develop biofuel technology based on increased electrification rates [57].…”

“…One approach is to calculate carbon emissions based on energy consumption during transportation and the corresponding carbon emission coefficients [20,32], which is a "top-down" approach. The other is to estimate energy consumption by the distance traveled and the transportation mode chosen and to then calculate the carbon emissions with the carbon emission coefficient for the energy type corresponding to the transportation mode [6,29,[33][34][35][36], which is a "bottom-up" approach. The former cannot distinguish the impacts of the different transport sectors on GHG emissions; the latter is prone to errors in the final results because some data need to be estimated.…”

Adjusting transportation structure to reduce the intensity of greenhouse gas emissions is an effective way to address climate change issues. This paper selects six transport sectors and constructs a hybrid input-output model to study the impact of transportation restructuring on the intensity of CO2 and non-CO2 greenhouse gas emissions in each sector during different periods. The results show that the effect of transportation restructuring on greenhouse gas emissions is manifested differently in different time periods. After 2008, transportation restructuring had a significant effect on reducing the intensity of greenhouse gas emissions in all sectors. However, the impact of transportation restructuring on the intensity of non-CO2 greenhouse gas emissions is limited. It is also found that the railway transport sector has been a low-impact transport sector in terms of greenhouse gas emissions since 2004, which provides insights for the optimization of China’s transportation structure.

“…Moreover, in addition to the need for a carbon-sensitive analysis, the corresponding accounting model needs to be constructed based on the appropriate accounting methods. The total emissions from the power plant are equivalent to the sum of mineral fuel burn-ing, desulfurization process emissions, and electricity emissions after net procurement within the company boundary [40][41][42]. Therefore, the data accounting model incorporates emissions from fossil fuels, the desulphurisation process, and the use of electricity after net procurement.…”

The emission of greenhouse gases poses enormous pressure on current carbon emissions and carbon reduction. Accurate quantification of carbon emissions from coal-fired power plants is of great significance for achieving the dual carbon goal. To enable enterprises to better understand their carbon emissions, this study constructs a carbon emission model and carbon emission data accounting model for coal-fired power plants. Case data calculations and a carbon emission reduction analysis were conducted. The experiment showcases that the carbon sensitivity of the inner side of the boiler under control conditions is higher than that of the operating parameters controlled on the inner side of the steam turbine, with a maximum total value of 16.67 g/MJ; the annual average low calorific value of coal remains between 16,000 kJ/kg; the activity level of coal remains between 30,000 TJ; and the oxidation probability of coal char during combustion fluctuates, with a maximum of 99.8%. In the calculation of coal-fired carbon emissions, the fitting difference between the emissions of generator unit 1 and generator unit 2 is maintained within 2%. Overall, the CO2 emissions of power plants involved in the study are generally high. The model built through this study has well analyzed the carbon emissions of power plants. It is of great significance for the actual carbon emission reduction of coal-fired power plants.
