American Red Cross: Ready Rating
Ready Rating is a program that helps businesses, schools and organizations become prepared for disasters and other emergencies. All in one place, Ready Rating members have access to one-of-a-kind tools, resources and information for evaluating and improving their ability to withstand disaster, maintain operations, and protect lives and property. Whether you are taking your first steps or have a fully-functioning emergency management program, the Ready Rating program can help you achieve a higher level of preparedness.

AirControlNET
PC-based database tool for conducting pollutant emissions control strategy and costing analysis. Overlays a detailed control measure database on EPA emissions inventories to compute source- and pollutant-specific emission reductions and associated costs at various geographic levels (national, regional, local).

Combined Heat and Power Emissions Calculator
The Combined Heat and Power (CHP) Emissions Calculator compares the anticipated carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), carbon dioxide equivalent (CO2e), sulfur dioxide (SO2), and nitrogen oxide (NOx) from a CHP system to those of a separate heat and power system.

Greenhouse Gas Equivalencies Calculator
Calculate and communicate your greenhouse gas reduction strategy, reduction targets, or other initiatives aimed at reducing GHG emissions.

Paint and Coatings Resource Center (PCRC) Volatile Organic Compounds (VOC) and Hazardous Air Pollutant (HAP) Calculators
Provides calculators that determine the VOC and HAP emissions from four different scenarios: (1) VOC, HAP emissions per gallon of coating, less water, where the weight of water per gallon is known; (2) VOC, HAP emissions per gallon of coating, less water, where the percent water by weight is known; (3) VOC, HAP emissions per gallon of solids; and (4) VOC, HAP emissions per weight of solids.

National Mobile Inventory Model (NMIM)
The National Mobile Inventory Model (NMIM) is a free, desktop computer application developed by EPA to help you develop estimates of current and future emission inventories for on-road motor vehicles and nonroad equipment.

 Office Carbon Footprint Tool
This tool was created for office-based organizations ("offices") located in the United States to assist offices in making decisions to reduce their greenhouse gas (GHG) emissions associated with their activities. This tool will allow the user to develop an estimate of their GHG emissions from a variety of sources including company-owned vehicle transportation; purchased electricity; waste disposal; and leased assets, franchises, and outsourced activities. It is not intended to address manufacturing operations or service-oriented businesses that use significant quantities of chemicals (e.g., cleaning services).

Cash Flow Opportunity Calculator
The Cash Flow Opportunity Calculator helps inform strategic decisions about financing energy efficiency projects. Using the tool, you will be able to estimate how much new equipment you can finance using anticipated savings, as well whether you should finance now or wait for a lower interest rate.

Commercial Energy Calculator
The Commercial Energy Calculator which will show you where your facility's energy dollars are going, and tips on how you can save money and energy.

Commercial Lighting Calculator
Compares the energy and cost savings of converting to an efficient lighting fixture.

Electronics Environmental Benefits Calculator
Estimate the environmental benefits of greening your purchase, use and disposal of electronics.

Building Life Cycle Calculator
The National Institute of Standards and Technology (NIST) developed the Building Life Cycle Cost (BLCC) Program to provide computational support for the analysis of capital investments in buildings.

WaterSense Start Saving Calculator
From the EPA’s WaterSense program, this calculator helps estimate how much water, energy, and money you can save by installing WaterSense labeled products in your home or apartment building.

Water Footprint Calculator
Welcome to GRACE’s Water Footprint Calculator (WFC) which features a brief set of questions that will get you thinking about how much water you and your household use and how water connects to almost every aspect of your life. The WFC will help you explore how you use water, estimate your household’s water footprint and learn ways to conserve.

National Recycling Coalition Recycling Calculator
Determine the GHG and energy benefits of current waste disposal practices.

Recycled Content (ReCon) Tool
Estimate life-cycle greenhouse gas (GHG) emissions and energy impacts from purchasing and/or manufacturing materials with varying degrees of post-consumer recycled content.

Electronics Environmental Benefits Calculator
Estimate the environmental benefits of greening your purchase, use and disposal of electronics.

RQ Calculator
Enter the name of a hazardous substance or its Chemical Abstract Service (CAS) number in the field above to look up its Reportable Quantity (RQ) or to evaluate whether a release to the environment must be reported to the National Response Center.
