Cities have their own responsibility for the reduction of greenhouse emissions in the fight against climate change.

Urban mobility is one of the main sources of pollutant emissions which seriously endanger people’s health, is related to CO2 emissions in the atmosphere and accounts for over 20% of the city’s energy usage. Cities are part of the problem, but also the solution. Therefore, Barcelona is moving towards a mobility that is free of fumes and is promoting a change of paradigm towards safe, sustainable, efficient and fair mobility. Because the way we get around must not affect the future of the planet or of the generations still to come. To mitigate climate change, the city has set the target of reducing its levels of CO2 by 40% in 2030, compared with 2005.
