34 Emissions Reduction Strategies A core element of an emissions roadmap is a description of strategies the airport plans to use to reach its ultimate emission goals. Chapter 4 provides guidance on how to identify and select these strategies.

Emissions Reduction Strategies 35 4.1 Reduce Scope 1 and Scope 2 Emissions This chapter provides guidance on identifying options for emissions reductions for Scope 1 and Scope 2. Because there are far too many potential strategies to include in this guidebook, the following text provides a high-level discussion of six strategies: energy efficiency, heating and cooling technologies, renewable electricity consumption, airport-owned and airport-operated vehicles, waste management, and other (Table 10)

The research team also reviewed the availability of emissions calculators and several tools, including emissions inventory tools, project-specific emissions evaluation tools, and costbenefits of emissions reduction strategies that exist to assist airports in emissions planning, as described in Table 12.

Guidance for each of these strategies can be found in ACRP Report 56.
