Climate & Energy

Reduce climate impacts through adaptation and mitigation efforts and increase resource efficiency

The 7 objectives in STAR’s Climate & Energy Goal Area aim to reduce climate impacts and increase resource efficiency in order to create safer, healthier, and more resilient communities. CE-1: Climate Adaptation and CE-2: Greenhouse Gas Mitigation are critical to achieving reductions in harmful climate impacts and promoting resource savings through decreased energy, water, and materials use.

Most of the objectives in Climate & Energy focus on achieving incremental increases in resource efficiency. CE-4: Energy Efficiency and CE-5: Water Efficiency encourage communities to reduce energy use over time in buildings and water consumption per capita. CE-6: Local Government GHG & Resource Efficiency offers local governments an opportunity to describe how their internal efforts demonstrate their leadership in this Goal Area. CE-3: Greening the Energy Supply complements the other objectives in the goal area by addressing the alternative energy sources for the transportation and the community’s electrical power supply.

Finally, through its ambitious waste reduction targets, CE-7: Waste Minimization rewards communities for efforts to reduce, reuse, and recycle materials.

Objective Number Objective Title and Purpose


Climate Adaptation: Strengthen the resilience of communities to climate change impacts on built, natural, economic, health, and social systems 


Greenhouse Gas Mitigation: Achieve greenhouse gas emissions reductions throughout the community 


Greening the Energy Supply: Transition the local energy supply for both transportation and non-mobile sources toward the use of renewable, less carbon-intensive, and less toxic alternatives 


Energy Efficiency: Minimize energy use and demand in the residential, commercial, and industrial sectors as a means to increase energy efficiency in the community 


Water Efficiency: Minimize water use and demand as a means to conserve water in the community 


Local Government GHG & Resource Efficiency: Lead by example by reducing local government greenhouse gas emissions and minimizing energy and water use in local government facilities and specified local infrastructure 


Waste Minimization: Reduce and reuse material waste produced in the community 

Each of the above objectives contains quantitative outcome and qualitative action measures. To see the evaluation measures, view the Climate & Energy section of the rating system.
