Issues Concerning Declared Energy Consumption and Greenhouse Gas Emissions of FAME Biofuels

Abstract

The paper deals with the issue of greenhouse gas emissions that are produced by the road freight transport sector. These emissions affect the structure of the ozone layer and contribute to the greenhouse effect that causes global warming-issues that are closely associated with changing weather patterns and extreme weather events. Attention is drawn to the contradictions linked to FAME (Fatty Acid Methyl Esters) biofuels, namely the fact that although their use generates almost zero greenhouse gas emissions, their production requires high levels of energy consumption. The first part of the paper deals with the theoretical basis of the negative impacts of transport on the environment and the subsequent measurement of the extent of the harmful emissions generated by the road freight transport sector. In the methodical part of the paper, the calculation procedures and declared energy consumption and greenhouse gas emissions generated by transport services are analyzed according to the EN 16258 standard. The experimental part of the paper focuses on the application of the methodology to a specific shipment on a specified transport route, where the total energy consumption and production of greenhouse gas emissions is determined. These calculations are based on comprehensive studies carried out for a particular transport company that assigned the authors the task of determining to what extent the declared energy consumption and greenhouse gas emissions change when the type of fuel used is changed.

Impact of the Electric Mobility Implementation on the Greenhouse Gases Production in Central European Countries

“…Global caused by GHG. They are emitted by many anthropological activities like industrial and transport activities [5][6][7].…”

Examining the Impact of Air Passenger Transport on International Long-Distance Regular Bus Transport in the Slovak Republic

“…Source: authors based on data from [16][17][18][19][20][21] , 0 0 (2018) 2018 https://doi.org/10.1051/matecconf /201823602007 MATEC Web of Conferences 236 LOGI From the point of view of prices, the bus transport is becoming more advantageous for destination to the Bratislava / Kosice -Prague and also for the destination Kosice -Vienna and Kosice -Warsaw. For the other compared destinations, air travel is even more advantageous in terms of cheapest airfares and not only travel time.…”

“…Another important determinant of traffic decision is the total time of transfer "from house to house" [21]. For example, bus travel time from Kosice to Prague ranges from 10 hours to 12.5 hours the flight time is 1 hour and 30 minutes.…”

New Technologies Improving Aerodynamic Properties of Freight Vehicles

“…The development of the vehicle design is focused on reducing this drag as much as possible and thus to combust less fuel and save money used for fuel purchase as well as to reduce negative impacts on the environment such as noise and emissions. Mainly exhaust gas emissions from vehicles have significant influence on global warming [2][3][4][5][6][7].…”
