The current CO2 emissions scale (Gton) magnitude is 5–6 orders greater than that of utilization (Mton). CO2 utilization should focus on its massive consumption, application of sustainable technologies, low-C energy sources and long-lasting products. CO2
The CO2 emission factors for natural gas (0.2 kg CO2/kWh) is obtained from the Swiss national inventory report (FOEN, 2023) and the CO2 emission factor for electricity generation is assumed to be 0.12 kg CO2/kWh (Krebs and Frischknecht, 2021). The current CO2 levy of 120 CHF/tonne CO2...
Average emission intensity for cars: Levon Amatun71, 228 g CO2-eq/km (4 passengers per car); Average emission intensity for buses: Levon Amatuni71, 187 g CO2-eq/km (30 passengers per bus); Average emission intensity for motorcycles: Gerson Carranza72, 97 g CO2-eq/km (1 passenge...
The global warming induced by the emission of greenhouse gases, especially the carbon dioxide, has become the global climate and environmental issues. Chin
If raw data of eNWarehouse−gas and eNWarehouse−electricity is given in m3/tonne-day and kWh/tonne-day, ENWarehouse−gas−container and ENWarehouse−electricity−container can be estimated in a similar way based on (24), (25).(24)ENWarehouse−gas−container=eNWarehouse−gas×...
