In 2015, Barcelona studied the impacts of climate change, analysing the main topics regarding the effects of climate change projections in the city: heat island effect, heat waves, urban flooding, sea flooding, biodiversity, fires, air quality, water cycle, energy flows and risk to infrastructure. The main results can be seen in lameva.barcelona.cat

Barcelona has launched its new Climate Plan on 2018. It’s an holistic Plan that takes into account Mitigation, Adaptation and resilience, Climate justice, and Promoting action by the general public.

It sets an example for other cities to be inspired and replicate as it has been the first ever Covenant Cities in the Spotlight awards among large-sized city signatories, and it also supports the goals of the Paris Climate Agreement, according to the revision made by C40s against their Climate Action Planning Framework.

All studies made during the vulnerability assessment have been used to define and prioritise adaptation and resilience measures, and during the oral presentation some of them will be highlighted.

For example, in the light of heat vulnerability index results of the city, we are developing a network of climate shelters (facilities and urban parks or water gardens that provide good thermal comfort conditions and which could shelter sensitive people in the event of heat waves. One of the goals of the Plan is to have 100% of the population at least 10 minutes on foot from a climate shelter .

Another example, in the light of water cycle vulnerability assessment is that we are going to need 18 hm3 of potable water in 2050. To solve this, we launched our Technical Plan for Taking Advantage of Alternative Water Resources, that calculates the demand and availability of groundwater, rain water and regenerated water.

Or to avoid urban floods or increase soil permeability, the Climate Plan are working on a new sustainable urban drainage strategy that offers design recommendations in a manual, maintenance protocols (with professional training to ensure it is done correctly) and recommendations on how to monitor and evaluate its effectiveness using monitors and sensors.

The Climate Plan recognises and fosters the key role of research in order to improve the information available at a local scale to support decision making and climate action implementation. In this respect, we are also committed to research projects, such as RESCCUE, aimed at contributing to broaden our knowledge on the impacts of climate change on urban systems.
