Cost-Effectiveness/Revenue Potential

We also wanted to compare the actions based on our three key metrics: (1) each action’s total greenhouse gas emissions reduction potential through horizon year 2050 (represented by the size of the bubble), (2) each action’s cost-effectiveness at reducing greenhouse gas emissions (represented by their relative position on the x-axis), and (3) their level of community benefits (represented by their relative position on the y-axis). Our findings show the different trade-offs--for example, the electrification action is more cost-effective at reducing greenhouse gas emissions than transit actions but generates fewer community benefits.

Revenue Generating Actions

Lastly, we compared cost-effectiveness at reducing greenhouse gas emissions by comparing the approximate cumulative capital and net operating costs of all the actions through 2050 with the approximate cumulative greenhouse gas emissions reductions through 2050.

• Tier 1: Very High (Net revenue generating between $209M and $5,000M in revenue for every cumulative mtCO2e reduced through 2050)

• Tier 2: High (Less than $500M for every cumulative mtCO2e reduced through 2050)

• Tier 3: Medium (Between $4,500M and $40,000M for every cumulative mtCO2e reduced through 2050)

• Tier 4: Lowest (Between $70,000M and $1,000,000M for every cumulative mtCO2e reduced through 2050)
