“…As emissions can hurt air quality and human health, certain technologies such as selective catalytic reduction (SCR) and diesel particulate filters (DPFs) can be used to reduce them when operating diesel engines. These technologies help to reduce pollutant emissions and improve the environmental performance of diesel engines [24].…”

There is a consensus on the need to reduce the emissions of carbon compounds. The increase in global greenhouse gas (GHG) emissions in the maritime industry poses a serious challenge to environmental sustainability, climate change, and the operating costs of ships. This article shows how hybrid versus diesel propulsion technology for ships can help reduce carbon dioxide (CO2) emissions and fuel consumption, and how these changes can be achieved. The need to reduce exhaust emissions and the increasing need for the shipping industry to seek alternative fuels means that existing regulations for marine engines and engine emissions are being updated almost constantly and new regulations are being formulated. The cost implications of the new regulations may lead to an increase in emissions as engines with lower fuel consumption are chosen, i.e., larger marine engines. Alternative approaches are needed to reduce CO2 emissions and fuel consumption, which could ultimately lead to hybrid propulsion for ships. This paper examines the current state of greenhouse gas emissions in shipping by analyzing the CO2 emissions and operating costs of two ships of the same type with similar technical and technological characteristics and different propulsion systems to gain insight into the problem. This paper compares the reductions in CO2 emissions, fuel consumption, and fuel costs for two suction hopper dredgers with standard diesel and hybrid propulsion. The technical characteristics, CO2 emissions, fuel consumption, and price of the two ships were analyzed to determine the advantages and disadvantages of each propulsion system. The novelty of this study is that two suction hopper dredgers from the same company with similar technical–technological characteristics but different propulsion systems were used for the case study and a mathematical procedure for calculating CO2 and other greenhouse gasses was presented in comparison, all to determine to what extent and in what way the hybrid propulsion system of a ship can contribute to reductions in CO2 emissions and fuel costs at the ship and company levels compared to a standard diesel propulsion system. This comparative analysis shows how much lower CO2 emissions, fuel consumption, and fuel cost savings can be expected when using a hybrid propulsion system compared to a standard diesel propulsion system. Finally, a conclusion is drawn on the efficiency and environmental compatibility of the two systems.

“…It is a very well-known fact that diesel has a negative impact on our planet [12,13]. This topic was addressed in publication [14]. However, taking into consideration that the energetic mix of many countries in the world is still mainly based on fossil fuels, it is easy to conclude that electric trains can also have a bad effect on the Earth.…”

There is a plethora of methods in the global literature that can be used to measure CO2 emissions from electrified transport. But are these methods reliable, and do they offer us a true view of how much exactly of this greenhouse gas is being produced by electric rail transport? We answer this question by proposing an improved CO2 emission estimation model based on cargo transport. Unlike other works, our studies include four crucial steps: (1) estimation of energy consumption in electrified rail cargo transport; (2) estimation of energy losses in the railway traction system and high voltage transmission lines; (3) CO2 emission estimation in traditional powerhouses; and (4) determination of the intensity of the CO2 emissions from electrified rail cargo transport. Based on our method, we concluded that the intensity of CO2 depends not only on the type of fossil fuel used for energy production but also on the parameters of the cargo train, such as its length and weight or the total number of wagon axles (which depend on wagon type). The achieved intensity of CO2 emissions in electrified rail cargo transport slightly varies from those reported in the global literature. Among the most important reasons responsible for this are the conditions under which these tests were conducted. Nevertheless, our results shed new light on how CO2 should be measured. We proved that the decarbonization of electrified rail cargo transport will never be possible without infrastructure modernization. In addition, based on a case study, we also delivered knowledge on how to reduce the environmental impact of electrified rail cargo transport.

“…Emission levels for motor vehicles have been set by regulations of the European Parliament and the Council, also known as European standards. These standards specify the permissible levels of carbon oxides, hydrocarbons and particulate matter in compression ignition engines [10]. According to estimates, these regulations reduced CO2 emissions 6 times compared to the EURO 1 standard, with a 97% reduction in particulate matter and eleven-fold reduction of hydrocarbons.…”

The actual problem of today is environmental pollution, and the main source of pollution is transportation. Air pollution from vehicles, especially in cities, has been a major problem worldwide for the past few decades. Last year we heard that diesel cars were the most polluting. Increasingly stringent emission requirements are being placed on these vehicles, so the pollution levels of newly produced vehicles are so low that they are equal to the emission standards of gasoline-powered vehicles. In recent years, global warming caused by carbon dioxide emissions has added another dimension to intense research efforts to develop more efficient engines and use low-carbon and renewable biofuels. Recently, very strict mass emission standards have been introduced, such as EURO 5-6. To measure the emissions of motor vehicles, unified cycles and test procedures have been developed, and harmonized by global test cycles, for all categories of vehicles to facilitate the transfer of information or technology exchange around the world. In Lithuania, the car fleet is 10-15 years old, so it is important to study the cars that drive on our roads. Cars of this age may not comply with the EURO 5-6 standard and therefore, for various reasons, pollute the city of Klaipeda with CO2 or NOx pollutants. It is interesting and relevant to see how many cars drive with indicators corresponding to the EURO standard. This study aims to find out the different values between actual and factory vehicle exhaust emissions through measurements. Vehicle emissions are measured using the SGA 400 exhaust gas analyzer. Comparing the test vehicles of different years of production according to the standards of EURO 1-6, it was noticed that the most polluting internal combustion engines run on gasoline, and their operating age reaches 15-18 years complying with the EURO 3-4 standards. The amount of emissions of diesel vehicles from the EURO 1-6 standard has decreased even up to 12.5 times.
