The article presents the results of the inventory of greenhouse gas emissions from motor vehicles in Poland in 2015. The inventory was developed in accordance with the applicable guidelines for the annual greenhouse gas emission inventory (Decision 24/CP.19 of the Conference of the Parties to the United Nations Framework Convention on Climate Change) by the National Centre for Emissions Management and Balancing (KOBiZE) at the Institute of Environmental Protection – the National Research Institute. The national annual gas emissions from road transport are presented, including: carbon dioxide, methane and nitrous oxide along with emissions of the above gases converted into carbon dioxide equivalents. Carbon dioxide makes up the largest share in carbon dioxide emissions. This is particularly evident in the case of road transport – the emission of gases other than carbon dioxide (methane and nitrous oxide) is several orders of magnitude lower than the emission of carbon dioxide. Carbon dioxide emissions from road transport account currently for approximately 14% of the total carbon dioxide emission in Poland.
