The european project Biogasmax puts in network, at a european level, the different experiments linked to biomethane in order to share experiences and to put in place the best practices for the urban transportation management.

Human activities, in particular transport, are partially responsible for the problems associated with the greenhouse effect, and therefore global warming.

A key short-term action consists in increasing the use of alternative fuels to reduce greenhouse gas emissions.

In terms of need of energy, the European Union is increasingly dependent on imported fossil fuel. However, •resources are limited, •the demand for energy is constantly increasing•oil products come from politically unstable regions•oil prices are rising.

Greenhouse gases emitted by fossil fuels trough combustion contribute to climate change. This complex situation leads significant ecological and economical risks for society.

That's why the European Commission engaged a serie of iniyiatives, including many that focus on the transport industry, which is almost dependent on oil. It has consequently launched a call for projects that focus on biofuels inside the framework “Biofuel Cities�.

Fossil fuel combustion (petrol, diesel, kerosene, gas,...) emits more than 3 billions tons of CO2 in the atmosphere each year. Biogas used as fuel (biomethane) can eliminate smog in the atmosphere and significantly reduce noise pollution.

The most environmentally harmful compounds (particles, non-methane hydrocarbons) are absent when biomethane is used. For example, using biomethane as a fuel in buses leads to a reduction of 95% in particles, 99% in sulphur compounds and 70% in nitrogen oxide, as compared to diesel buses.
