The subject of this paper work was methanol and the IGF codex. The work is structured from 13 chapters, and in the same I dealt with topics that talk about methanol itself, methanol as an alternative fuel, and the IGF code that was adopted by the IMO as a need for a certain safety standard. The very beginnings of using methanol go back 40 years, when the first legal regulations regarding environmental protection began to be applied. Today, due to the increasing use and use of ship traffic, alternative fuels such as methanol, biodiesel... actually fuels that are less polluting by their combustion than the fuels that are used now are being considered. Due to the increasing use of alternative fuels whose properties are very different from those of standard fuels, the need for certain safety standards is beginning to appear. For this purpose, the IGF code was adopted, which sets certain standards that the ship as a whole (crew and ship) must respect in order to use alternative fuel as a propellant.
