Carbon accounting rules decoded
In an era where climate change is not just a buzzword but a business reality, the concept of carbon accounting has swiftly transitioned from a novel idea to an indispensable tool for modern businesses.
Carbon accounting, at its core, is a mechanism for quantifying the greenhouse gas emissions resulting from corporate activities. This process, akin to financial accounting, goes beyond mere number crunching to provide a narrative of a business’s environmental impact.
Originating in the early 2000s, carbon accounting today stands at the intersection of environmental responsibility and corporate governance.
What sets carbon accounting apart is its role in enabling organisations to understand and manage their carbon footprint. This understanding is not just a compliance requirement; it is a strategic imperative.
By quantifying emissions, businesses can identify key areas for reduction, thereby not only mitigating environmental impact but also optimising operational efficiencies and driving innovation.
The process of carbon accounting involves two critical steps: data collection and processing. This process demands comprehensive data gathering, encompassing both business activities and emissions factors, followed by a rigorous methodology to translate this data into meaningful insights.
The methodologies employed, whether spend-based, activity-based, or a hybrid approach, offer varying degrees of accuracy and relevance depending on the business context.
The Greenhouse Gas Protocol, the most widely recognised standard for carbon accounting, advocates a pragmatic approach combining both methodologies to achieve the most accurate emissions profile.
The protocol breaks emissions sources down into three categories called ‘Scopes’:
The rationale for integrating carbon accounting into business operations extends beyond regulatory compliance. It encompasses several strategic dimensions:
Understanding PPN 06/21
A significant development in the realm of carbon accounting has been the UK Government’s mandate, under Procurement Policy Note (PPN) 06/21, for applicable organisations to publish their Carbon Reduction Plans from September 30, 2021.
The term ‘In-Scope Organizations’ within PPN 06/21 generally refers to entities engaged in contracts valued at £5 million per annum or more (excluding VAT). This encompasses a wide range of businesses, making the policy a significant driver in the UK’s broader strategy for carbon reduction in the corporate sector.
PPN 06/21 mandates these organisations to calculate their greenhouse gas (GHG) emissions following the GHG Protocol carbon accounting standard. While the target-setting process mirrors that of the Science Based Targets initiative (SBTi), there are notable differences in the approach.
The policy necessitates organisations to fill out a succinct form which requires a declaration of current and future GHG emissions across Scope 1, Scope 2, and select categories of Scope 3. This process is integral to setting a clear trajectory towards achieving net zero carbon by 2050.
Ultimately, carbon accounting is more than an exercise in compliance. It is a conduit to a more sustainable and resilient business model.
By enabling businesses to measure, manage, and report their environmental impact, carbon accounting is not just responding to a global challenge but is reshaping the very way businesses operate in the 21st century.
As accountants navigate an increasingly environmentally-conscious business environment, carbon accounting emerges not just as a tool but as a catalyst for transformation, driving businesses towards sustainability, efficiency, and innovation.
