CO2SYS is a family of software programs that calculate chemical equilibria for aquatic inorganic carbon species and parameters. Their core function is to use any two of the four central inorganic carbon system parameters (pH, alkalinity, dissolved inorganic carbon, and partial pressure of carbon dioxide) to calculate various chemical properties of the system.
EPA tools and programs such as Power Profiler, Portfolio Manager, the WasteWise Office Carbon Footprint Tool, the Green Power Equivalency Calculator, the Personal Greenhouse Gas Emissions Calculator, and the Greenhouse Gas Equivalencies Calculator use eGRID. Other tools such as labeling/environmental disclosure, Renewable Portfolio Standards ...

In the following, a short introduction to input-output analysis and its environmental extension for the calculation of material footprints or RME indicators is provided. The inter-industry flows within an economy form an n × n matrix Z and the total output of each industry forms an n ×1 vector x .
Concentrations in ppm of the major greenhouse gases between 1978 and 2010. Greenhouse gas monitoring is the direct measurement of greenhouse gas emissions and levels. There are several different methods of measuring carbon dioxide concentrations in the atmosphere, including infrared analyzing and manometry.

Monitoring methodologies are more specific than GHG Protocol or ISO 14064, and require the use of continuous monitoring systems, mass balance calculations, or default emission factors. [67] EPA uses the facility-level and supplier data to help prepare the annual Inventory of U.S. Greenhouse Gas Emissions and Sinks, which is submitted to the ...
