Know, map and regulate risks, considering the current and future impacts of climate F1 change • Sustainable Mobility - Promote sustainable mobility based on low carbon options and through the optimization of the F2 territorial organization of people and activities (proximity urbanism), reducing travel / distances • Ecosystem services - protecting and enhancing ecosystem services F3 • Renewable energy - Development / exploitation / exploitation of renewable energy sources F4 • Environmental efficiency - Reduce the consumption of primary resources by increasing environmental efficiency F5 (energy, water, materials and soil) and enhance the transition to a circular economy Mitigation Adaptation (mitigate the causes: reduce GHG (adapt to the effects: changes in activities emissions / increase carbon sequestration) and lifestyles) (F1) Know, map the risks and regulate land uses, considering the impacts of climate change (current and future) • maps of susceptibility and exposed elements (floods, coastal overturns, coastal erosion, forest fires, heat waves, cold waves, etc.) • prohibited / permitted and conditioned uses in risk areas • relocation of buildings in risk areas • areas, infrastructures and rescue equipment Mitigation Adaptation (mitigate the causes: reduce GHG (adapt to the effects: changes in activities emissions / increase carbon sequestration) and lifestyles) (F2) Sustainable mobility - Optimizing the territorial distribution of people and their activities (reducing travel) • size of agglomerates, densities, locations with mixed uses and accessibility - proximity urbanism • mobility with less GHG emissions and air pollutants (F4) Use of renewable energy sources • large-scale production from renewable sources • location criteria for solar and wind farms, incompatibility and complementarities of uses • micro-generation of renewable energy production • conditions for exploration in buildings Mitigation Adaptation (mitigate the causes: reduce GHG (adapt to the effects: changes in activities emissions / increase carbon sequestration) and lifestyles) (F3) Protection and enhancement of ecosystem services (climate and flood regulation, provision, air and water purification, soil maintenance, food production, pest control and biodiversity protection) • Know and map the services provided by ecosystems • Protect, value and enhance • Recover and promote the use of Green Infrastructures / Municipal Ecological Structures • Regulate agricultural and forestry practices (F3) Maintenance / increase of carbon sequestration capacity - ecosystem services • in soil, water bodies and species Mitigation Adaptation (mitigate the causes: reduce GHG (adapt to the effects: changes in activities emissions / increase carbon sequestration) and lifestyles) (F5) Environmental Efficiency - Resilient and adaptive urban planning • Improve the thermal comfort of buildings and the responsiveness of public spaces to climatic events, incorporating adaptive solutions (planning conditions, design and construction standards) (F5) Increase in environmental efficiency (energy, water, soil and materials) • More efficient buildings that make the most of their resources and emit less GHG (planning conditions, sustainable building code) SHEET N.º Thematic 1.

Location: Rotterdam (Netherlands) The “water square” combines water storage with improving the quality of urban public space. Sponge areas Ghent Watercity Location: Ghent (Belgium) The project develops around 5 ambitions: more space for water, greener banks, better transport along and over water, better water quality and "city like a sponge" F1 Risks Green Roofs Location:Toronto (Canada) In February 2006, Toronto adopted the Green Roof Strategy to encourage the construction of green roofs in the city Temperature control and runoff in an urban contexto Location: Berlin (Germany) Establishes that the construction of new buildings requires a proportion of the area to be left as a green space Sustainable mobility policy - balanced modal split The city of Copenhagen defined a mobility policy that designated 3/3: 1/3 of journeys by bicycle, 1/3 of journeys in public transport, 1/3 of journeys by car Achieve sustainable mobility by regulating access to urban vehicles in the city Reduction in transport emissions by 30%. Complementary measures: - more housing within city limits; - improvement in public transport infrastructure and F2 cycle paths; -increase parking fees; -promote sharing; - encourage less travel; - Sustainable stimulate the acquisition of less polluting vehicles Mobility Incentives for electric mobility in London London has the ambition to become a carbon-free city by 2050.
