Also known as greenhouse gas (GHG) accounting, carbon accounting is a way for managers and analysts to measure a company’s total carbon emissions.
It’s a comprehensive approach to analyze how a company uses energy for its buildings, offices, conveyances and production processes. Carbon accounting examines firsthand, secondhand and tertiary energy uses.
Environmental, Social & Governance
Looking at ESG standards (Environmental, Social & Governance), it’s not only becoming encouraged, it’s becoming required for businesses, especially for publicly traded businesses. Whether it’s the U.S. Securities and Exchange Commission (SEC) or other governmental agencies in the global economy, these administrative organizations are mandating emission declarations for businesses to account for their carbon emissions. It’s also necessary for third parties (lenders, potential and current investors) to review and analyze a company’s current and past performance, along with industry comparisons.
It’s important to distinguish the differences between carbon and GHG accounting. Carbon accounting only looks at carbon dioxide emissions, while GHG looks at the broader category and illustrates why doing so is important. Businesses look at nitrous oxide and hydrofluorocarbons (HFCs), for example, when accounting for GHGs. However, such measurement is based on the so-called carbon dioxide equivalent or C02e. This helps standardize GHGs into the C02e standard for carbon accounting, giving government and interested parties the ability to measure across a universal standard. Two common uses for this standard are for carbon offsets and credits.
Calculating Emissions
1. Scope 1 factors in emissions from the company’s directly controlled or owned assets. Examples include factories, production, conveyances, etc.
2. Scope 2 looks at what the business uses in regard to climate-controlled services for their factories, offices, etc. It also looks at the company’s contracts with power suppliers.
3. Scope 3 factors in indirect emissions the business may incur. This includes commercial commuting activities, investing, how assets are disposed of, etc.
According to the SEC, Scope 3 emissions must include those “upstream and downstream activities in a company’s value chain” if they’re necessary for investor consideration or if the business has pledged to meet certain metrics for Scope 3 levels.
From there, a business’ activity metrics are calculated according to governmental and industry standards, such as the U.S. Environmental Protection Agency, ISO Standard 14064, or The Climate Registry’s General Reporting Protocol, etc. Businesses’ results are presented against past results, where they discuss how they will improve their efficiency internally and work with their supply chain partners.
Compliance
While compliance is one important reason, third-party audiences, such as family offices, institutional money managers, lenders, etc., are equally as important. Asset managers and family offices, for example, look for ESG or environmentally friendly investments to attract retail or “smart-money” investors. Similarly, activist investors, especially those looking to make companies more environmentally friendly, can look at companies to see how their carbon emissions stack up against their industry and overall commercial peers.
Another consideration is that by meeting regulatory or industry requirements and meeting ESG standards, businesses could qualify for preferential or market rates for funding from the debt markets.
Conclusion
The more companies are well-versed in this type of accounting, the better they will meet government and investor expectations.
