For centuries, man has been making inventions to improve his living conditions in terms of travel, health, food, housing and in so many other areas. To move, he uses means some of which contribute to the destruction of the environment. In Guinea, for example, 90% of the means of land transport are cars and motorcycles which during circulation escapes carbon dioxide which contributes to air pollution. Ecological mobility is very low in this country those who use the bicycle, which is an ecological means of transport, do so to practice sport, few of them use it to travel and these are children. The problem is that in Guinea there is no specially reserved track for cyclists. The rate of people who also regularly walk to work or to run errands is low. Encouraging ecological mobility is a way to preserve our environment. Governments must also invest in this area to encourage the population to adhere to ecological mobility for the well-being of all. Eco-mobility or sustainable mobility is a concept that has emerged in the wake of questions of sustainable development, to designate the design, implementation and management of modes of transport deemed less harmful to the environment, safe and economical, in particular with a lower contribution to greenhouse gas emissions. Eco-mobility is easier to implement, and therefore more often practiced, in urban areas. Technical means and alternatives exist, and political measures have shown positive effects in some cities or regions, but a major challenge, according to David Banister, remains the transition, which involves putting in place the conditions for change and acceptability of alternatives to “unsustainable” transport. These conditions imply a high quality implementation of innovative and efficient systems, and they require finding the trust and acceptance of many stakeholders as well as active participation.
