U radu je opisan razvoj propisa o dopuštenim emisijama štetnih tvari iz motora s unutarnjim izgaranjem u Europi u razdoblju od 1970. godine do danas, s osvrtom na njihov razvoj u budućnosti. Osim na zakonski ograničene emisije štetnih tvari, dan je osvrt i na zahtjeve na gorivo potrebne za ispunjavanje propisa Euro 5 i 6 kao i na emisiju CO2, plina koji nije zakonski ograničen, ali je staklenički plin na kojeg se odnosi sporazum iz Kyota.
Znatan napredak u smanjenju emisija štetnih tvari postignut je kontinuiranim poboljšavanjem tehnika pročišćavanja ispušnih plinova i uporabom sve kvalitetnijih goriva. Pritom treba naglasiti da se kvalitete goriva koje zahtijeva Svjetska povelja o gorivu Worldwide Fuel Charter - WWFC, koja predstavlja želje proizvođača motora, razlikuju od kvalitete goriva koju zahtijevaju propisi EU. Razvoj budućih propisa o emisiji i zahtjeva za kvalitetom goriva predstavlja isprepletene želje i mogućnosti proizvođača motora i vozila, proizvođača goriva, politike i zakonodavstva te pritiska „zelenih“. Posebnu težinu za donositelje zakonskih propisa u EU ima činjenica da je EU ovisna o uvozu goriva i svojevrsni je lider na području primjene alternativnih goriva i donošenja novih strožih propisa vezanih za emisije štetnih tvari.The paper describes the development of regulations on approved harmful substances emissions from internal combustion engines in Europe from the year 1970 till today, and it also emphasizes their development in the future. Apart from legally restricted use of harmful substances emissions, it also discusses the requirements for fuels which need to be met according to Euro 5 and 6, as well as the CO2 emission, which is not restricted by the law but it is the greenhouse gas covered by the Kyoto Protocol.
A considerable progress has been made in reducing the harmful substances emissions by the constant improvement of cleaning techniques of gas emissions and by the use of more quality fuels. Here we need to emphasize that the quality of fuels required by the Worldwide Fuel Charter – WWFC, which represents the wishes of engine manufacturers, differs from the quality of fuels required by the EU regulations. The development of the future regulations on the emissions and the requirements on the quality of fuels combines the desires and possibilities of engine and vehicle manufacturers, fuel manufacturers, politics, legislation and the pressure of the green activists. The fact that the EU depends on the fuel import and stands out as the leader in the field of alternative fuel use and bringing new, more stringent regulations on harmful substances emissions has a great impact on the body behind the new regulations in the EU
