Carbon accounting, also known as greenhouse gas (GHG) accounting, is the process of measuring, tracking, and reporting the greenhouse gas emissions that a business produces, both directly and indirectly. You can think of it like financial accounting, but instead of focusing on money, it focuses on the climate impact of an organization's activities. The primary goal is to quantify an organization's carbon footprint, understand its environmental impact, and set goals to reduce emissions.

Why is it important?

• Compliance: Many governments and industry bodies are implementing regulations that require businesses to report their GHG emissions. Carbon accounting helps companies meet these obligations and avoid penalties.
• Strategy: It provides businesses with the data they need to develop effective strategies for reducing their environmental impact and working towards net-zero emissions.
• Customer and Investor Relations: Many customers and investors are increasingly concerned about a company's environmental performance. Transparent carbon accounting can enhance a brand's reputation and attract support.
• Efficiency: Often, activities with a high carbon cost are also inefficient. By identifying and reducing these, companies can sometimes save money.

How does it work?

Carbon accounting typically involves categorizing emissions into three "scopes" as defined by the Greenhouse Gas Protocol:

• Scope 1: Direct Emissions These are emissions from sources directly owned or controlled by the company.
  • Example: Emissions from burning fuel in company vehicles (e.g., a delivery truck fleet) or from a factory's on-site boiler.
• Scope 2: Indirect Emissions from Purchased Energy These are emissions from the generation of electricity, heat, or steam that the company purchases.
  • Example: The emissions produced by the power plant that generates the electricity an office building uses for lighting and computers.
• Scope 3: Other Indirect Emissions These are all other indirect emissions that occur throughout a company's value chain, both upstream and downstream. This is often the broadest and most challenging scope to measure.
  • Example: For a clothing retailer, Scope 3 emissions could include emissions from cotton farming, textile manufacturing, shipping, customer use of the clothing, and even its disposal. Or, for a software company, it might include emissions from employees commuting, business travel, the manufacturing of purchased raw materials, and waste disposal.

The emissions are usually measured in "carbon dioxide equivalent" (CO2e), which allows different greenhouse gases (like methane and nitrous oxide) to be expressed as a single unit based on their global warming potential.

Example:

Let's say a t-shirt manufacturing company wants to implement carbon accounting:

1. Baseline Measurement: The company first measures its emissions for a year to establish a baseline.

   • Scope 1: They calculate the emissions from the fuel used by their factory's machines and the delivery trucks they own to transport raw materials and finished goods.
   • Scope 2: They calculate the emissions from the electricity purchased to power their factory and offices.
   • Scope 3: This is more complex. They would track emissions from:
     • The cultivation of cotton (raw material).
     • The manufacturing of the fabric by their suppliers.
     • The shipping of cotton and fabric to their factory.
     • Employee commutes to the factory and offices.
     • Waste generated during the manufacturing process.
     • The energy consumers use to wash and dry the t-shirts.
     • The disposal of the t-shirts at the end of their life.

2. Setting Targets: After getting their carbon footprint (e.g., 1,000 tons of CO2e in the baseline year), the company might set a goal to reduce their emissions by 20% over the next five years.

3. Reduction Strategies: Based on their accounting, they might discover that a significant portion of their emissions comes from electricity consumption (Scope 2). They could then invest in solar panels for their factory or switch to a renewable energy provider. For Scope 3, they might work with their cotton suppliers to encourage more sustainable farming practices or optimize their shipping routes to reduce fuel consumption.

4. Reporting: Annually, they would track their emissions again and report their progress against their targets to stakeholders and potentially to regulatory bodies. If they produce 1,000 tons of carbon via operations, they may need to secure at least 1,000 carbon credits to remain compliant and negate their carbon footprint.
