Most SMEs would agree that carbon accounting seems daunting given limited resources.
But it doesn't have to be. By breaking down key concepts and outlining practical steps, carbon accounting can be simplified for SMEs to understand and implement.
This article explains carbon accounting terminology, compares common methods, and provides actionable guidance to get started. You'll learn flexible approaches to fit your SME's needs and resources on the path to transparency and emissions reductions.
Introduction: The Significance of Carbon Accounting for SMEs
Small and medium enterprises (SMEs) have a critical role to play in reducing global greenhouse gas emissions. Although individual SME contributions may seem minor, collectively they represent over 90% of businesses and more than 50% of employment worldwide. With stakeholder expectations and regulations evolving rapidly, tracking and reporting emissions is becoming an imperative for SMEs. However, most lack the extensive resources for complex carbon accounting processes. User-friendly, automated solutions are key to overcoming these barriers.
Understanding the Climate Imperative for SME Engagement
The latest IPCC report paints an urgent picture - global emissions must be halved by 2030 to meet Paris Agreement goals. With SMEs representing the majority of commercial enterprises, their collective climate impact is substantial. Proactively measuring and reducing emissions is not just socially responsible, but also smart long-term risk management. Being an early mover will pay dividends as sustainability becomes mainstream.
The Rise of Stakeholder Expectations for Carbon Transparency
From shareholders to customers, SMEs are facing increasing demands for climate transparency. Investors are ramping up engagement to understand portfolio emissions, while multinationals expect disclosures across their supply chain. New regulations also loom, like the EU's Corporate Sustainability Reporting Directive covering mid-sized companies. Getting ahead of these expectations through carbon accounting helps SMEs access capital and contracts.
Navigating Resource Constraints in Carbon Accounting
While climate awareness is growing among SME leadership, dedicating extensive financial and human resources to carbon accounting remains challenging. Complex methodologies like Life Cycle Analysis may be inaccessible. This amplifies the need for straightforward carbon accounting solutions that simplify data collection and monitoring without compromising accuracy. The path to net-zero requires pragmatism in adoption.
What is carbon accounting in accounting?
Carbon accounting is the process of measuring, quantifying, and reporting an organization's total greenhouse gas emissions. Similar to financial accounting, carbon accounting provides an overview of climate impact by tracking carbon emissions associated with business activities.
This involves calculating emissions produced directly by the company, as well as from purchased electricity, employee travel, supply chains, investments, and other sources. Once total emissions are quantified, companies can identify high-impact areas to target for reduction.
Carbon accounting data allows businesses to:
- Track and report annual emissions
- Benchmark against industry averages
- Model future reduction plans
- Identify efficiency opportunities
- Engage stakeholders on progress
Why is carbon accounting important?
Carbon accounting is important for several reasons:
- It increases transparency and accountability around climate impact. Companies have a responsibility to understand and reduce emissions.
- Reporting emissions is becoming an expectation from investors, customers, regulators, and the public. This reporting requires accurate carbon accounting.
- It enables data-driven strategies for lowering emissions and reaching goals like net zero. What gets measured gets managed.
In summary, carbon accounting provides the underlying data to benchmark, report, and drive decarbonization efforts. As climate change impacts grow, rigorous carbon accounting will only increase in importance for businesses.
What is the difference between GHG accounting and carbon accounting?
Although the two terms are similar and often used interchangeably, there is a subtle but key difference.
Carbon accounting refers only to carbon dioxide (CO2) emissions. Carbon dioxide is a greenhouse gas that contributes to global warming and climate change. Carbon accounting measures the amount of CO2 emitted by a company's operations, products, and supply chain. It provides vital data to track progress towards emission reduction targets.
GHG accounting refers to all greenhouse gases (GHGs). In addition to CO2, this includes methane, nitrous oxide, and other gases. Reporting on all GHGs gives a more complete picture of environmental impact.
GHG accounting is also the basis for the mandatory reporting under widely adopted frameworks like The Greenhouse Gas Protocol Corporate Standard. By measuring all GHGs, companies ensure they comply with the full scope of required disclosures for sustainability reporting.
As environmental, social, and governance (ESG) principles become more mainstream in business, both carbon and GHG accounting are essential. Companies need detailed emissions data to set science-based targets, engage stakeholders on climate action, and demonstrate tangible progress over time. Automated solutions can remove the complexity from emissions calculations and reporting.
In summary, carbon accounting focuses specifically on CO2, while GHG accounting is more comprehensive in measuring all greenhouse gases. Companies need both as part of a robust sustainability management strategy.
What are the stages of carbon accounting?
Carbon accounting has evolved through four key stages:
Environmental accounting focus
Early carbon accounting focused narrowly on tracking direct environmental impacts and natural resource usage. This involved quantifying raw materials consumed, waste generated, and examining activities specifically related to environmental management.
While foundational, this approach failed to account for greenhouse gas (GHG) emissions and climate impacts. Businesses realized that to improve sustainability, they needed to transition to directly tracking carbon outputs.
Direct carbon dioxide focus
The next stage centered on calculating direct carbon dioxide (CO2) emissions from operations. This marked a shift towards quantifying GHG emissions, providing greater visibility into climate impacts.
Companies began tracking CO2 from sources they owned or controlled, like facilities, vehicles, and manufacturing. This enabled basic carbon reporting and helped businesses identify areas to lower emissions.
Direct and indirect greenhouse gas emission focus
As climate change concerns heightened, carbon accounting expanded to cover all GHGs from both direct and indirect activities.
In addition to operational sources, this also involved calculating emissions from purchased electricity and upstream supply chains. This lifecycle approach as per Greenhouse Gas Protocol provided a more comprehensive emissions profile.
Climate impact focus
Current best practices focus on translating emissions data into tangible climate impacts. This allows companies to better understand environmental damage, inform strategic decisions, and communicate sustainability progress.
Techniques like shadow carbon pricing and science-based target setting help businesses evaluate climate risks and pursue aggressive mitigation actions. More sophisticated climate modeling integrates geospatial data to reveal localized environmental impacts.
This evolution shows how carbon accounting has increased in rigor and utility to address intensifying decarbonization demands. Though advancing in complexity, automated solutions help streamline analysis while unlocking additional environmental insights.
Is carbon accounting effective?
Carbon accounting can be an extremely effective way for SMEs to measure, understand, and reduce their carbon footprint. By tracking emissions across scopes 1, 2, and 3, companies gain visibility into not just their own operational emissions, but also emissions from their supply chain and the use of their products and services.
With clear carbon accounting, SMEs can identify the largest sources of emissions and focus their efforts on targeted reductions. For example, switching to renewable energy, improving energy efficiency in buildings and transport, or changing procurement policies to favor low-carbon materials and services. These measures often lead to cost savings too.
More broadly, goods and services with high carbon costs tend to be resource-inefficient. By scrutinizing these expenditures through carbon accounting, companies can often find ways to cut costs and emissions simultaneously. The transparency and insights gained allow SMEs to make strategic, cost-effective decisions to decarbonize their business.
So in summary, well-implemented carbon accounting gives SMEs the information they need to reduce their environmental impact in a smart, streamlined way. As stakeholders demand increased climate action and regulation intensifies, thorough carbon accounting will only become more crucial for SMEs seeking to lower costs, risks, and emissions on the path to net zero.
Demystifying Carbon Accounting for SMEs
Carbon accounting can seem daunting for small and medium enterprises (SMEs) just getting started on their sustainability journey. However, grasping some key terminology and principles can simplify the process. This section will provide readers with essential background on what carbon accounting entails and metrics like emissions scopes, inventory boundaries, and intensity ratios.
Carbon Accounting Explained: Terminology and Principles
Carbon accounting refers to measuring greenhouse gas (GHG) emissions associated with business operations and the supply chain. It involves creating an emissions inventory - a quantified list of emission sources alongside data collection methodologies. Inventory sources are categorized into scopes per the Greenhouse Gas Protocol:
- Scope 1 covers direct emissions from owned/controlled operations. This includes fuel combustion, vehicles, fugitive refrigerants, and more.
- Scope 2 accounts for indirect emissions from purchased electricity and heating.
- Scope 3 encompasses all other indirect emissions across the supply chain like raw materials, transportation, waste, etc.
Other key terms:
- Carbon sequestration refers to long-term carbon capture via sinks like forests or soil. This can offset some operational emissions.
- Carbon offsets allow companies to invest in verified external emission reduction projects to compensate for residual emissions they cannot eliminate.
- Carbon accounting focuses specifically on quantifying emissions, while carbon reporting publishes the results to stakeholders.
By grasping these basic principles, SMEs can better understand evaluations of their carbon footprint.
Determining the Scope of Your Carbon Inventory
A critical first step is delineating your company's organizational boundary for the emissions inventory. This depends on the level of financial or operational control your business has over different units. Common considerations include:
- Are emissions from subsidiaries, joint ventures, or franchise outlets included?
- How many tiers upstream and downstream in your supply chain will the inventory encompass? Going beyond tier 1 vendors/transport can provide greater visibility into hotspots.
- Do you collect data associated with specific sites/facilities only or cover all operations company-wide?
Defining these inventory boundaries and securing buy-in across the organization is imperative before collecting data. Carbon accounting software can aid in automatically mapping emissions sources to scopes based on your business structure.
Utilizing Intensity Ratios to Measure Emissions Over Time
While absolute emissions provide a snapshot of your carbon footprint, intensity ratios enable benchmarking and goal-setting as your company evolves. These metrics track emissions relative to an organization-specific denominator like:
- Per unit of economic productivity (tCO2e/million $ revenue)
- Per unit of physical production (tCO2e/unit product)
Monitoring intensity ratios over time shows decoupling of emissions from growth. Setting intensity reduction targets also builds flexibility into sustainability planning as the business scales.
By covering essential carbon accounting terminology and decisions around inventory scopes, companies can establish a strong emissions quantification foundation. Pairing this with intensity ratio tracking creates a management system for driving down environmental impacts amid growth and disruption.

Practical Steps for Starting Carbon Accounting in Your SME
Taking the first steps to understand your company's carbon footprint can seem daunting, but it doesn't have to be. Here are some practical and feasible ways for resource-constrained SMEs to initiate carbon accounting practices internally.
Choosing the Right Carbon Accounting Approach
The best carbon accounting methodology depends on your business needs, available data sources, and budget constraints. Begin by taking stock of existing operations data you can leverage. If you already track business metrics like energy usage, raw materials, waste, etc., compiling this information can provide an initial footprint estimate.
For many SMEs, an emissions intensity ratio benchmarking approach offers an accessible starting point. Using industry averages, you can estimate emissions relative to a key business activity like per unit of product manufactured, miles driven, square footage, or full-time employees. As data collection matures, a more robust inventory methodology like the Greenhouse Gas Protocol provides greater accuracy.
Ultimately, balance accuracy with feasibility. Starting small is better than not starting at all - even limited or estimated data has value for informing strategy and benchmarking progress over time. The key is institutionalizing carbon accounting into routine business processes.
Gathering Essential Data for Your Carbon Baseline
While complex methodologies track all Scope 1, 2, and 3 emissions sources, focus first on the largest and easiest to collect data sets. For most SMEs, gathering 12 months of historical data on energy usage, transportation and distribution, raw material inputs, solid waste generation, and employee commuting will account for 70-80% of emissions.
Prioritize tracking direct emissions sources first with supplier-provided usage data (like electricity bills), odometer logs, fuel expenditures, etc. Estimates based on spend, mileage reimbursements, square footage, or units produced can proxy some data gaps. While tracking indirect supply chain emissions comes later, supplier engagement is an opportunity to spread good carbon accounting practices.
Regularly compiling this information into a centralized database, spreadsheet, or carbon accounting software ensures consistent tracking over time - enabling SMEs to build robust carbon inventories.
Benchmarking with Industry-Specific Emissions Intensity
For SMEs just starting out, benchmarking carbon intensity ratios can provide an initial emissions baseline estimate while primary operations data is gathered. Referencing reputable industry analyses and market intelligence reports can give useful rule of thumb estimates.
For example, U.S. manufacturing produces around 0.7 metric tons of CO2e per $1,000 USD of economic output. So if your company generates $5 million in annual sales revenue, you could reasonably estimate an annual carbon footprint around 3,500 metric tons to baseline against. These types of back-of-the-envelope calculations based on sector emissions factors offer feasible shortcuts while capacity for more advanced methodologies develops.
Over time, replacing intensity ratios with granular bottom-up data improves accuracy. But having a fast way to approximate the carbon footprint delivers an important starting point for SMEs new to carbon accounting practices.
Translating Carbon Metrics into Reduction Strategies
Carbon accounting provides the foundation for developing data-driven decarbonization strategies. By quantifying emissions across your organization's operations, you gain visibility into emissions hotspots to target for reduction. As part of a long-term net zero strategy, carbon insights should fuel ongoing iterations of goal-setting, execution, and performance tracking.
Focusing on Emissions Hotspots for Immediate Impact
Pinpointing the activities generating the highest proportion of emissions allows you to prioritize and achieve maximum reduction impact. As an example, for a manufacturer the top hotspots may be raw material usage and on-site energy consumption. By substituting carbon-intensive materials or transitioning to renewable energy sources, impactful cuts can be attained to progress towards science-based targets. Regular carbon accounting updates make clear how each initiative moves the needle.
Exploring Scenario Planning for Achievable Reduction Goals
With baseline emissions data from carbon accounting, scenario modeling provides a framework for setting ambitious but realistic reduction targets. Working backwards from long-term net zero visions, you can strategize stepping stone objectives by playing out decarbonization initiatives over specified timeframes. Forecasting how emissions transform in response to each potential pathway informs executable interim and incremental goals to include in your strategy.
