The global warming is defined as increase of average temperature of the Earth's near-surface air and the oceans. There are different gases emitted responsible for this effect, mainly: water vapor, CH4, N2O and CO2. According to the recent knowledge, it is supposed that apart from water vapor, CO2 can have the highest influence on global warming. Carbon dioxide emission sources can be divided into two groups: nature (eruption of volcano, water evaporation, and so on) and anthropogenic. Economic development caused that anthropogenic factor has more share in global greenhouse gases emission. This phenomenon occurrence is connected with transport development, which can be divided into the following groups: aircraft industry, automotive industry, railway transport, construction of ships, aerospace industry. EU directive concerning CO2 emission reduction caused many applied technologies to become unprofitable considering environmental preservation. Due to that, there is an urgent need of creating new or modifying existing technological solutions - especially in the field of materials engineering - resulting in further technological development, especially in such branches like automotive and aircraft industry. The idea of decreasing the weight of vehicles is not a new challenge and it has been taken up by many research groups. The effects are mainly observed in reduction of vehicles body weight which directly influences the CO2 emission decrease. However, in case of vehicles' parts subjected to wear or/and contact fatigue (engine, gears e.g. gearbox) the use of light weigh alloys gives rise to many difficulties. A research in this field may bring another reduction of vehicles' total weight. However, the use of titanium, aluminum or magnesium alloys by their nature can cause an increase of wear and lower the contact fatigue resistance. In this work, the base problem of greenhouse gases emission was explained. Moreover, after market analysis the application of aluminum alloys in transportation was proposed and the potential use in exposition to semi or high load and wear was described.
