BC3 – Basque Centre for Climate Change participates at the 2020 European Mobility Week. Since 2002, EUROPEANMOBILITYWEEK has sought to improve public health and quality of life through promoting clean mobility and sustainable urban transport. The campaign gives people the chance to explore the role of city streets and to experiment with practical solutions to tackle urban challenges, such as air pollution. BC3 as an interdisciplinary research centre on the causes and consequences of climate change takes the opportunity to show the research that we are doing to understand the impact of mobility in the climate emergency.
