Maritime transportation has been a cost-effective option among other transport modes. Meanwhile, this demand has been increasing day by day because of the expanding global economy. The ships are one of the most important transport and trade vehicles in the world; 90% of the world trade is carried out by maritime transport, and this sector plays a crucial role in climate change and global warming because it is one of the key sectors leading to emissions of carbon dioxide, the main greenhouse gas (GHG). In other sectors that lead to CO2 emissions, i.e., energy production, manufacturing industry, and heating in residences, energy efficiency has been improved and emissions have been reduced significantly. However, there has been no net reduction in the transport sector; total CO2 emissions have also increased because of the continuous increase in freight and passenger traffic, although efficiency has increased. Increasing the energy efficiency of a ship allows for fuel consumption reduction and GHG emissions. In this study, the energy system of a chemical tanker ship was analyzed and then modeled by using the long-range energy alternatives planning system, a widely used platform for energy policy analysis and climate change mitigation assessment, including a comprehensive energy flow diagram, namely, reference energy system. A base scenario was developed, and the ship’s energy system was convenient to be analyzed and evaluated in terms of technical, economic, and environmental aspects, including low-emission development strategies, to comply with marine engine regulations of the International Maritime Organization.

Carbon Dioxide Co2

Prior research on the empirical relationship between anthropogenic carbon dioxide (CO2) emissions and economic growth, as measured by increases in gross domestic product (GDP), indicate that a 1% growth in GDP can lead to anything between an increase in emissions by 2.5% to a decline by 0.3%. Studies have paid little attention to independent mechanisms that reduce emissions. Statistical properties of the data undermine the estimation techniques used in many studies. To address these shortcomings, we used novel methods and panel data integrating emissions, economic, and energy-system characteristics across 70 economies over 1970-2013 to derive a universal GDP-emissions relationship and identify key emissions-reduction mechanisms. We found that, robust to a variety of estimation procedures, every 1% increase in GDP was associated with a 1% increase in CO2 emissions when controlling for other mechanisms. Emissions reductions were mainly driven by four mechanisms: (i) energy system decarbonization, (ii) increased economic efficiency, (iii) electrification, and (iv) deindustrialization. A 1% increase in these factors was associated with 0.2-1.8% reductions in CO2 emissions per year; together, these factors contributed to 18 petagrams of emissions reduction globally over 1970-2013. Decarbonization contributed most to emissions reductions in high-income economies, while economic efficiency and electrification contributed most to reductions in low-income economies.

Carbon Emission Reduction

This paper takes the regional energy internet as the research object, and combines the power system, primary energy system, transportation system, and thermal energy system to give the system boundary. First, the mathematical decomposition method and the logical integration method were combined to decompose the total low-carbon capability into seven single low-carbon capabilities. On the basis of the mechanism of carbon emission reduction, a comprehensive calculation model for CO2 emissions reduction of the energy internet was then established. Finally, taking the Yanqing Energy Internet Demonstration Zone in China as an example, it was calculated that the model could reduce CO2 emissions by 14,093.19 tons in 2025. The results show that the methods adopted in this paper avoided the overlap calculation reasonably well; the comprehensive calculation model of CO2 emissions reduction has strong versatility, and can quantitatively calculate the carbon emission reduction amount for any completed or planned energy internet. Among the seven low-carbon capabilities, “replacement of gasoline with electricity” had the highest contribution rate, with a value of 42.62%, followed by “renewable energy substitution” (37.13%). The innovations in this paper include: (1) The problem of reasonable splitting of the overlapping parts in carbon emission reduction calculations being solved. (2) The first comprehensive calculation model of CO2 emission reduction on the energy internet being established. (3) The contribution of the seven low-carbon capabilities of the energy internet to total emissions reduction being clarified.
