• Commuter Fuel Cost Calculator
  This worksheet will calculate the amount of money you spend on fuel for your commute, how much each passenger should contribute to the fuel cost, and how much money you save by ridesharing.
• Energy and Cost-Saving Calculators for Energy-Efficient Equipment
  The energy and cost calculators allow companies to enter their own input values (e.g., utility rates, hours of use, etc.) to estimate energy and cost savings for energy-efficient products for lighting, commercial and industrial equipment, equipment for food service, and office equipment.
• GHG Emissions : Conversion to CO2e
  This worksheet will convert the entered quantity from the chosen units into carbon dioxide equivalent (CO2e) emissions.
• Green Cleaning Pollution Prevention Calculator
  This calculator quantifies the projected environmental benefits of purchasing and using "green" janitorial services and products. It forecasts the environmental benefits of reducing chemical use by doing some or all pollution prevention measures typically involved in the routine interior cleaning of an office building. It enables users to identify which green cleaning measures will have the greatest impact in reducing their use of hazardous chemicals.
• Recycling Conversion Factors
  Organizations that recycle can use this guide to determine standard volume-to-weight conversion factors.
• Reportable Quantity (RQ) Calculator
  Companies that handle hazardous substances can use this calculator to evaluate whether a release to the environment must be reported to the National Response Center.
• Secondary Containment Calculation Worksheet: Construct New Secondary Containment
  SPCC Plan New Construction Worksheet to Determine Dike or Berm Dimensions for Secondary Containment: This worksheet can be used to determine the possible dimensions for a rectangular or square dike or berm to meet the secondary containment requirement for aboveground bulk storage containers.
• Secondary Containment Calculation Worksheet: Multiple Horizontal Cylindrical Tanks Inside a Rectangular or Square Dike or Berm
  Secondary Containment Calculation Worksheet: Multiple Horizontal Cylindrical Tanks Inside a Rectangular or Square Dike or Berm: This worksheet can be used to calculate the containment volume of a rectangular or square dike or berm for multiple horizontal cylindrical tanks. When there are other objects or structures such as tanks along with the largest tank within the dike or berm, their respective displacement volumes must be accounted for when determining secondary containment.
• Secondary Containment Calculation Worksheet: Rectangular or Square Remote Impoundment Structure
  Secondary Containment Calculation Worksheet: Rectangular or Square Remote Impoundment Structure: This worksheet can be used to calculate the containment volume of a rectangular or square remote impoundment1 structure providing secondary containment for an aboveground tank storage facility.
• Secondary Containment Calculation Worksheet: Single Vertical Cylindrical Tank Inside a Rectangular or Square Dike or Berm
  Secondary Containment Calculation Worksheet: Single Vertical Cylindrical Tank Inside a Rectangular or Square Dike or Berm: This worksheet can be used to calculate the secondary containment volume of a rectangular or square dike or berm for a single vertical cylindrical tank. This worksheet assumes that there are no other objects or structures within the dike or berm that will displace the volume of the secondary containment.
• Site Assessment Calculators
  This suite of on-line calculators can be used to assess transport of environmental contaminants in the subsurface. The purpose of these calculators is to provide methods and data for common calculations used in assessing impacts from subsurface contamination.
• Units Conversion Worksheets
  This series of worksheets will convert the entered quantity from the chosen units to other common units of mass, length, area, volume, pressure, and temperature.
• Waste Reduction Model (WARM)
  WARM can help solid waste planners and organizations track and voluntarily report greenhouse gas (GHG) emissions reductions and energy savings from several different waste management practices. Use this worksheet to describe the baseline and alternative municipal solid waste (MSW) management scenarios that you want to compare.
