Prioritize Greenhouse Gas Mitigation Strategies

Questions to Answer

  1. What portfolio of activities will get the agency to its Scope 1 & 2 target?

  2. What portfolio activities will get the agency to its Scope 3 target?

Once a Federal agency understands what greenhouse gas (GHG) reductions are feasible and at what cost, proposed GHG reduction activities may be prioritized. While it may be useful for personnel responsible for managing GHG emissions to prioritize actions within emission categories—for example, prioritizing building emission reduction measures—prioritization should also occur across all major emission Scope 1 & 2 emission sources and all Scope 3 emission sources.

Guidance on prioritizing strategies for specific emission sources includes:

Prioritizing actions across fleet, facility, and fugitive sources will enable the agency to define the portfolio of activities that will get the agency its Scope 1 & 2 target most cost effectively. For more information, see Prioritize Strategies and Set Internal Reduction Targets for Scope 1 & 2 GHG Emissions.

Prioritizing actions across employee commute, business travel, and other Scope 3 sources will enable the agency to define the optimal portfolio of activities to achieve its Scope 3 target. For more information, see Prioritize Strategies and Set Internal Reduction Targets for Scope 3 GHG Emissions.

The prioritization approach used can vary based on the agency's needs and available resources. For some, a general assessment of costs and benefits will be adequate. For others, a more formal rank-ordering of actions with weighted criteria will be necessary to support investment decision-making.

Next Step

When a prioritized portfolio of projects is identified, an agency can start following the guidance in the next step, Establish Internal Greenhouse Gas Emission Reduction Targets. It will help establish appropriate internal targets for different programs and sites.
