The commonly used metric to measure a company's carbon emissions is the carbon footprint. This term specifically refers to the total amount of greenhouse gases, primarily carbon dioxide, that are emitted directly or indirectly by a company’s activities or operations, typically calculated in terms of carbon dioxide equivalent (CO2e).

The carbon footprint provides a clear and quantifiable means of assessing how much a company contributes to climate change through its emissions. Organizations use this metric to set targets for reduction, implement strategies to lower their impacts, and report on sustainability efforts to stakeholders.

In contrast, energy efficiency ratings gauge how effectively a company utilizes energy in its operations without necessarily providing a comprehensive view of that company's total greenhouse gas emissions. Water usage and waste generation, while important aspects of environmental impact, do not directly equate to measuring carbon emissions specifically and thus do not serve as appropriate metrics for that purpose. This specificity makes the carbon footprint the most relevant and widely recognized measure for assessing a company's carbon emissions.
