Comparative analysis of GHG emission calculation procedures according to EN 16258 and ISO 14083

Emissions of greenhouse gases (GHG) such as carbon dioxide, nitrous oxide, and methane are significant transport products. The 2012 European standard EN 16258 introduced a methodology for calculating and declaring emissions, but its application has been limited to the European environment. The Global Logistics Emissions Council (GLEC) initiated the steps that led to adopting the international standard ISO 14083 in 2023. ISO 14083 provides a global framework for accurately calculating and reporting emissions from transport chains and represents a key step towards international standardization. Unlike EN16258, ISO 14083 has worldwide validity in ISO member countries. However, despite its advantages, it is still little known, and many haulers use outdated procedures according to EN 16258. Raising awareness of this standard and its implementation is essential to ensure consistent and accurate monitoring and calculation of emissions on a global scale. The article identifies and highlights the differences between the two standards and their impact on GHG emission calculation results.
