Policy Solution

Light pavement

Mandate

Overview:

Summary: Light-colored materials and reflective coatings or overlays serve to reflect heat instead of absorbing and retaining it. In addition to decreasing temperatures, these treatments can also extend the pavement lifetime.

Implementation: Set mandates such as zoning amendments to use lighter and more reflective materials for any repaving.

Considerations for Use: Consider who uses the pavements, how, and what is surrounding the area to determine if reflective pavements are appropriate to implement. Local technology and product availability may also determine implementation cost.

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

    MandateMandates are government regulations that require stakeholders to meet standards through building codes, ordinances, zoning policies, or other regulatory tools.
  • 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.
    Introducing new or updated zoning/codesIncludes codes, zoning requirements or by-laws pertaining to urban planning and building construction activity.
    No-regrets actions (low cost/low effort but substantial benefit)Interventions that are relatively low-cost and low effort (in terms of requisite dependencies) but have substantial environmental and/or social benefits.
