EPA created the Waste Reduction Model (WARM) to help solid waste planners and organizations track and voluntarily report greenhouse gas (GHG) emissions reductions from several different waste management practices. WARM calculates and totals GHG emissions of baseline and alternative waste management practices—source reduction, recycling, anaerobic digestion, combustion, composting and landfilling.
The WARM tool is a downloadable spreadsheet.
EPA has a suite of emissions estimation tools for a variety of applications. They include:
Did you ever wonder what reducing carbon dioxide (CO2) emissions by 1 million metric tons means in everyday terms? The greenhouse gas equivalencies calculator can help you understand just that, translating abstract measurements into concrete terms you can understand, such as the annual emissions from cars, households, or power plants. This calculator may be useful in communicating your greenhouse gas reduction strategy, reduction targets, or other initiatives aimed at reducing greenhouse gas emissions.
Every paint, even powder, contains two kinds of components, that end up in two different places. The parts you want (the "solids") end up on what you are painting. The rest (the liquids, or "volatiles") end up in the air. As a painter, you may not be immediately interested in what happens to the volatiles once they have floated off. But some volatiles (the so-called volatile organic compounds, or "VOCs") contribute to air pollution, and some volatiles (the hazardous air pollutants, or "HAPs") are known to be particularly toxic. So whether or not you're paying much attention to the volatiles, you should be aware that the environmental regulatory agencies are.
That is why there are regulations that limit the amount of VOCs or HAPs that you are permitted to release. In order to determine whether you are operating within those limits, you are asked to calculate the VOC or HAP content of the paints you use. But the calculations can be somewhat complicated.
The PCRC has developed the Emissions Calculator to help you through those calculations. If you are not familiar with the ideas behind emissions calculations, please read this guide. It is intended to help you understand the thinking behind the regulations, and to show why some of the complications are unavoidable if the regulations are to be applied fairly and effectively.
