The expanding and highly greedy Algerian transport sector is totally depending on petro-products, due to the rising numbers of automobile fleets and the excessive dependence on road transportation. Irrecoverable Greenhouse gases GHGs emitted by this sector are constantly increasing. As a result, consumption of diesel and gasoline reached record levels. Consequently, there is a strong need of cleaner, eco-friendly and economically viable alternative fuels. Biofuels, electric, compressed natural gas CNG, liquefied petroleum gas LGP vehicles, are expected to play a crucial role in meeting energy and environmental policies targets. In this paper, the Algerian transport sector perspectives and Greenhouse gases mitigations, in different shaped scenarios based on semi-empirical models, are analyzed and discussed. For adequate policy shaped in a scenario, in 2050, annual Algerian consumption could decrease up to 35%, 43% of CO2 emissions and 73% of NOx emissions could be mitigated compared to no-intervention scenario. These promising findings indicate the huge potential of resource diversification on the transportation sector. Therefore, implementing such policies is fundamental for a durable Algerian’s transportation sector transition policy.
