Policy Solution

Public shading structures

Commitment

Overview:

Summary: Shading structures can provide comfort for pedestrians and also serve as public space. Shade can come from nature-based solutions like trees or manmade structures. Shade can also extend to public transportation lanes and stops (see "Cooled transit stations").

Implementation: Include shading in the public realm as part of master plans to implement in appropriate areas such as park and pedestrian corridors. This may include introducing shade requirements and removing barriers to implementing shading structures.

Considerations for Use: Shade in the form of tree canopy and public space is often disproportionately distributed throughout neighborhoods and areas with vulnerable populations should be prioritized for pilot programs.

  • Policy Levers: The mechanism municipalities can use to actualize the intervention. These policy levers will likely be used in combination with each other.

    CommitmentGovernments set ambitious goals or targets to guide prioritization and investment.
  • Trigger Points: Opportunities for municipalities to implement risk reduction and preparedness interventions based on the policy lever, building on the United Nations Environment Programme triggers used in the Beating the Heat handbook (2021).

    City planning processesIncludes city initiatives such as the development of climate action plan, pathway to zero-energy, master plan, transit plan, energy mapping etc.
    Evaluating or initiating major city infrastructure projectsIncludes projects such as city transit, street or utilities construction / re-construction etc.
    Preparatory measures (actions to establish authority to act)Actions to establish/ ensure the authority to act when appropriate trigger-points occur.
