<p>The transport sector is the second largest emitter of global greenhouse gas emissions. For this reason, the global community is currently making a lot of efforts to decarbonize transport: active electrification of transport is underway, various subsidies are introduced to stimulate demand for more environmentally friendly types of transport, requirements for the sulfur content in bunker fuel are tightened, etc. However, few people think about how futile all these actions can be without paying due attention to the optimality of logistics in world trade. In this article, calculations were made based on geopolitical restrictions introduced between Russia and Western countries since 2022, as well as a scenario of reduced trade through the Red Sea (observed in 2024). According to the calculation results, it was revealed that the annual increase in emissions due to suboptimal logistics only in the trade of Russian hydrocarbons and the redirection of goods through the Bab el-Mandeb Strait instead of the Red Sea will amount to 630–690 million tons of carbon dioxide equivalent (CO₂-eq). This exceeds the total emissions from all economic sectors in countries such as Australia, Turkey, Spain and Argentina, or even the UK and the Netherlands. Therefore, international logistics is another key area that deserves close attention when formulating tasks in terms of decarbonization of the global transport sector, in particular, and global low-carbon development in general. That is, the sanctions policy and various geopolitical restrictions can negatively affect the achievement of the goals of the Paris Agreement, which is an integral part of the Sustainable development goals (SDGs).</p> Graphical Abstract <p></p>
