Frequently asked questions (FAQs) about carbon accounting software and tools

What is carbon accounting?

Carbon accounting, also known as greenhouse gas (GHG) accounting, quantifies an organization's greenhouse gas emissions, directly or indirectly, within defined boundaries.

Much like financial accounting, which measures financial impact, carbon accounting tracks climate impact by calculating an organization's carbon footprint. This method estimates emissions from various activities and converts them into carbon dioxide equivalents (CO2e) using global warming potential (GWP) metrics. 

Organizations can identify emission hotspots and focus their reduction efforts on high-impact areas by understanding their carbon emissions.

Carbon accounting not only aids in emission reduction but also supports organizations in reporting climate impact to stakeholders, such as customers, investors, and regulatory bodies.

As of May 2024, 2023, many countries, corporations, and organizations representing a large portion of the world's economic output have pledged to achieve net-zero greenhouse gas emissions by 2050.

The Greenhouse Gas Protocol is the most commonly used framework for calculating and classifying GHG emissions into three scopes, enabling comprehensive and standardized reporting.

What is an example of carbon accounting?

To understand carbon accounting, consider a practical scenario involving a manufacturing firm. This company is committed to reducing its environmental impact and utilizes a specially developed carbon accounting software.

Step-by-Step Process:

  1. Data Collection: Initially, the software gathers detailed information on emissions from all relevant sources within the company.
  2. Analysis: Next, this data is analyzed to pinpoint areas where emissions are most concentrated, known as emission hotspots.
  3. Target Setting: Based on these insights, the company sets specific, measurable targets aimed at reducing emissions in the identified hotspots.
  4. Reporting: Finally, the firm prepares detailed environmental performance reports. These reports are crucial as they are shared with stakeholders, including investors, customers, and regulatory bodies, providing transparency regarding the company’s environmental endeavors.

This example illustrates how carbon accounting plays an essential role in helping organizations manage and reduce their ecological footprints effectively.
