EnviroCalc for Environmentally Preferred Purchasing (EPP)
This calculator helps procurement agents estimate the environmental benefits of purchases of recycled content and energy efficient products. Purchasing these products helps agencies consume less energy, produce less waste, conserve landfill space, save trees and other natural resources, reduce greenhouse gas emissions, and protect public health. While not all of these impacts are easy to quantify, the calculator allows purchasers to estimate the following:
Recycled content paper products:
- Landfill space savings
- Wood savings
- Energy Savings
- Greenhouse gas emissions avoided
Recycled content plastic products:
- Landfill space savings
- Energy Savings
- Greenhouse gas emissions avoided
Remanufactured toner cartridges:
- Landfill space savings
- Energy Savings
Re-refined motor oil and recycled antifreeze:
- Equivalent usage by number of cars
Recycled content office furniture:
- Landfill space savings
Recycled mulch:
- Landfill space savings
ENERGY STAR© compact fluorescent (CFL) bulbs:
- Energy Savings
- Greenhouse gas emissions avoided
ENERGY STAR© monitors:
- Energy Savings
- Greenhouse gas emissions avoided
ENERGY STAR© copiers:
- Energy Savings
- Greenhouse gas emissions avoided
ENERGY STAR© fax machines
- Energy Savings
- Greenhouse gas emissions avoided
EnviroCalc contains four main sheets — two for entering purchasing data for recycled content and energy efficient products, and two for viewing estimated benefits by product type and by benefit. Specific instructions for each product type are provided on the data entry worksheets.
Sustainability Officers and Procurement Agents both will find this tool useful for reporting on the impacts of an environmentally preferred purchasing (EPP) policy. It provides metrics that are easily understood and that can be used for tracking progress towards sustainability goals.
