Carbon Accounting in the UK: An Overview
Amidst environmental worries and climate change, consumers, investors, and CEOs emphasize mindful environmental business practices. A World Economic Forum study found that over 90% of CEOs prioritise sustainability, highlighting the need for carbon accounting in the UK to meet evolving demands and regulatory shifts. Carbon accounting has emerged as a crucial tool for businesses to measure, manage, and disclose their carbon emissions.
In this blog, we provide an in-depth overview of carbon accounting: its definition, the process of conducting carbon accounting, the challenges involved, and the opportunities it presents.
What is Carbon Accounting?
Carbon accounting, meaning the process of quantifying and documenting the greenhouse gas (GHG) emissions produced by an organisation or enterprise, is crucial for businesses. The primary greenhouse gas of concern is carbon dioxide (CO2), but other gases like methane (CH4), nitrous oxide (N2O), and fluorinated gases are also considered in the assessment. While emissions may be the result of any of these gases, the standard unit for measuring emissions is CO2e (carbon dioxide equivalent) - a unified way to express the contribution of each GHG to climate change. The goal of carbon accounting is to determine an organisation's carbon footprint, which reflects its contribution to climate change.
How is Carbon Accounting in the UK Done?
For those looking for a carbon accounting overview, the process of carbon accounting involves a systematic approach to quantifying and documenting a company’s greenhouse gas emissions. The first step in carbon accounting involves identifying and categorising the sources of emissions within the organisation. These emission sources are categorised into three scopes:
- Scope 1: Direct emissions from sources that are owned or controlled by the organisation, such as emissions from the combustion of fossil fuels in company-owned factories and facilities.
- Scope 2: Indirect emissions from purchased electricity or heating.
- Scope 3: Indirect emissions that occur because of the organisation's activities, but from sources not owned or controlled by them. This includes emissions from the entire value chain, including suppliers, transportation, and even customer use of products.
Once the sources are identified, data management takes place. Business data is collected and processed from the company’s various internal departments and across all value chains. The data is then profiled through matching with appropriate emission factors that specify the associated estimate amount of greenhouse gas emissions involved.
The next step is the measurement of emissions, companies must establish a baseline of their Scope 1, 2 and 3 emissions. For effective carbon accounting, businesses must obtain accurate and comprehensive measurements across all scopes of emissions. While enterprises have more control over their Scope 1 and 2 emissions, measuring their Scope 3 emissions is challenging.
Dialling in on calculating Scope 3 emissions, there are a variety of methodologies that companies can utilise, hinging on industry averages, proxies, and other sources. Enterprises are advised to select methods which ensure that the inventory appropriately reflects the GHG emissions of the activities, and serve the decision-making needs both internally and externally.
The final step in the carbon accounting process is reporting and verifying data. This means that emissions data is compiled into reports and disclosed to stakeholders such as investors, customers, and regulatory authorities. External verification and assurance of the reported carbon accounting data may be conducted to enhance credibility. Businesses can use frameworks such as the Greenhouse Gas (GHG) Protocol Corporate Standard to report their emissions data.
Challenges in Carbon Accounting
While carbon accounting plays a pivotal role in addressing climate change and promoting sustainable business practices, it is not without its challenges. Some of the key challenges that businesses may face when quantifying GHG emissions are:
- Data collection: One of the major challenges in carbon accounting is obtaining accurate and comprehensive data from various sources. This requires cooperation from all departments and may be resource-intensive and expensive for some enterprises. Many suppliers also may not measure their emissions at all, and those who do measure, may not be open to sharing data due to confidentiality or contractual issues.
- Data accuracy: Ensuring data accuracy is crucial for credible carbon accounting. Businesses that are unable to collect granular data will have to rely on estimated data and industry averages to calculate their emissions. This can lead to inconsistent and inaccurate data, which in turn can lead to misinformed decision-making.
- Lack of reporting standardisation: A universally accepted standard for carbon accounting is lacking, resulting in a diversity of reporting frameworks including the Global Reporting Initiative (GRI), Task Force on Climate-Related Financial Disclosures (TCFD), International Sustainability Standards Board (ISSB), Carbon Disclosure Project (CDP), and the upcoming European Sustainability Reporting Standards (ESRS). Notably, the ISSB mandates usage of the GHG Protocol Corporate Standard for GHG accounting, whereas the CDP permits alternative methods like ISO 14064-1 or national methodologies. This array of approaches can complicate the management of reporting.
Under the UK’s existing Streamlined Energy and Carbon Reporting (SECR) framework, reporting supply chain emissions was voluntary. However, the landscape is on the verge of significant change. With various nations, such as the EU, US, Singapore, and Australia, transitioning towards making comprehensive climate-related information disclosure mandatory, certain UK-based companies will soon be required to quantify and disclose their Scope 3 emissions. In 2024, the UK government intends to embrace the new worldwide climate disclosure standard, enhancing global comparability and rendering the disclosed information more valuable for investors.
Carbon Accounting as an Opportunity
While there are challenges on the path to robust carbon accounting for businesses, there are also a wealth of opportunities. There are several ways in which businesses can benefit from committing to carbon accounting practices, including -
- Sustainable business practices: Carbon accounting allows businesses to identify emission reduction opportunities and operational inefficiencies. By understanding their carbon footprint, businesses can take targeted actions to reduce emissions as well as improve operational resilience.
- Stakeholder demands: Investors and customers are increasingly demanding transparency and accountability regarding the carbon footprints of the businesses they invest in. By embracing carbon accounting and disclosing emissions data, businesses can adhere to the changing consumer landscape and also attract environmentally conscious investors, gaining a competitive advantage in the market.
- Benchmarking and accountability: Carbon accounting gives businesses the opportunity to understand and analyse their sustainability performance relative to previous years. Companies can use benchmarking to assess their environmental impact as well as the effectiveness of their decarbonisation strategies. By investing in carbon accounting, enterprises can be accountable not only to investors, consumers and regulators but to themselves as well.
- Policy and Regulatory Compliance: Many countries and regions are implementing mandatory reporting requirements and regulatory frameworks related to carbon emissions. Carbon accounting will help businesses align with these regulations and demonstrate their commitment to environmental responsibility. This will also help them avoid any potential legal, financial, or reputational penalties for non-compliance. Moreover, participation in voluntary initiatives and carbon markets can create additional opportunities for businesses to offset emissions and contribute to carbon neutrality.
