EE Prerequisite: Environmental Protection Disclosure

(Required)

Applicable to: Cities and Utilities, Campuses, Transit

INTENT

To measure and make public the environmental consequences of power generation, transmission, and distribution.

REQUIREMENTS

All projects

Evaluate the environmental impact of electricity consumption, using the PEER EE index and the following formulae:

Overall performance metrics are the sum of the SEI, CO2, NOx, SO2, water intensity, and waste intensity for each generation source:

Where:

TDLi = Transmission and distribution losses (%) for generation source i (equals 0 for local generation)

WasteIi = 0 for nuclear and biomass, for rest of the fuel types please refer to the reference guide (or) EE Index calculator.

Table 1. Methane leakage multipliers

Fuel	Multiplier
Coal	1.037
Natural Gas	1.130
All Other Fuel Types	1.000

Sum the EE index scores corresponding to the values shown in Table 2. The first five metrics in Table 2 are maximums: the project’s value must not exceed the listed figure. The “waste recycled” metric, however, is a threshold: the project’s value must equal or exceed the listed figure.

Additionally, establish a public disclosure policy to publish the results of environmental impact evaluations in the project’s annual performance and/or sustainability reports.

Projects that own or operate local or backup generation sources must meet following requirements: 

• Have in place a process to record fuel consumption, water consumption, and energy output data for all local and backup generation units. 
• Have in place a policy to verify the emissions performance of local and backup generation units through third-party testing at least once every three years.
• Demonstrate compliance with regional environmental regulations applicable to the local and backup generation units, including emissions, waste handling and disposal, water consumption, and land use.
