Heat-resilient environmental impact assessments (EIA)
Most Environmental Impact Assessments (EIAs) do not take impacts on the urban heat island effect into consideration. Governments should incorporate a new development’s adverse effects on its surrounding environment in the context of heat (e.g. building mass, increased pedestrian temperatures, greenhouse gas emissions, etc.) in environmental impact assessments.
Amend existing EIAs to include heat considerations.
Considerations for Use
To support the transition to an amended EIA, host trainings to educate staff and stakeholders on updated EIA methodologies.
Climate:Cold, Hot/Dry, Hot/Humid, Temperate
Policy Levers:MandateMandates are government regulations that require stakeholders to meet standards through building codes, ordinances, zoning policies, or other regulatory tools.
Trigger Points:City planning processesIncludes city initiatives such as the development of climate action plan, pathway to zero-energy, master plan, transit plan, energy mapping etc.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.
Phase of Impact:Risk reduction and mitigation
Metrics:Number of permits that incorporate UHI considerations
Intervention Scale:City, State/Province
Authority and Governance:City government, State/provincial government
Implementation Timeline:Short-term (1-2 Years)
Implementation Stakeholders:City government, Private developers
Funding Sources:Public investment
Capacity to Act:High
