Shrinking city beaches, due to the rise in sea level

Flooding caused by the rise in sea level is calculated by using the flood level. This is determined by three parameters: 1. localised rain at average sea level which causes constant flooding; 2. the tide and changes in pressure and the wind which generate potential flooding; and 3. the swell effect, the root cause of the main problems on Barcelona’s coastline during extreme storm episodes.



Barcelona’s eight beaches are at high risk from sea storms.


Increased flooding is forecast, along with morphological changes to the beaches and increased exposure of the port infrastructure.

Measures implemented so far

  • Preventing the loss of sand caused by sea storms and protecting the seafront.
  • Mitigation: 45% reduction in greenhouse gases compared to 2005.
  • The objective is to decelerate global warming. To this end, Barcelona is working on a process of energy transition and a change in the city model.  
  • Action is being taken to foster energy saving and increase energy efficiency, to renovate buildings and to achieve a greater production of local, renewable energy. We are also promoting more sustainable mobility, where priority is given to pedestrians, cyclists and public transport. This is why the general public has a vital role to play in the fight against climate change.
  • The City Council has drawn up a mitigation plan which complements the Climate Plan by spelling out how the mitigation measures that should allow us to achieve the Climate Plan’s reduction targets will be rolled out.
  • The starting point for this plan was an analysis of the city’s energy situation and the sectoral studies carried out for the 2011-2020 Energy, Climate Change and Air Quality Plan.
  • Here you can consult the latest energy report and the sectoral studies.
  • Energy consumption and greenhouse gas emissions in Barcelona have gone down in recent years, by 2% and 31% respectively between 1999 and 2014, and especially since 2005, when they peaked.
  • The city has been able to consume less energy per euro generated. According to data from 2015, energy consumption and the generation of emissions are increasing again, with an upward trend forecast for the coming years. There is a need to spread a new energy culture that uncouples economic growth from energy consumption.
  • Fossil fuels account for 47.24% of the city’s total primary energy consumption, nuclear for a further 47.8% and renewables for just 5.68% (according to the Catalan mix).
  • With regard to the source of electricity, 74.49% of what we consume comes from nuclear power. Renewable sources only account for 8.69% of the electricity Barcelona consumes.
