published on 06 December 2023

Most business owners would agree that accurately tracking carbon emissions can be incredibly challenging for small and medium enterprises (SMEs).

Yet it doesn't have to be. This article will present a straightforward, user-friendly approach to carbon accounting that SME professionals can easily adopt.

You'll discover simplified techniques and tools for crafting an emissions inventory, analysing results to pinpoint reductions, and implementing cost-saving sustainable strategies across your organisation.

Introduction: The Essentials of Carbon Emissions Accounting for SMEs

As an SME, understanding and managing your carbon footprint is increasingly important for both environmental responsibility and business growth. This guide simplifies carbon emissions accounting, demonstrating its value for streamlining sustainability efforts.

The Significance of Carbon Emissions Accounting for SMEs

Carbon accounting provides many benefits for SMEs:

  • Regulatory compliance: Tracking emissions allows SMEs to comply with current and emerging climate regulations like SECR or CSRD. Non-compliance risks financial penalties.
  • Investor confidence: Some shareholders and lenders prioritise sustainability. Documented emissions management inspires investor confidence in an SME's future readiness.
  • Competitive edge: With 71% of consumers favouring eco-conscious brands, sustainability boosts customer acquisition and loyalty. Robust carbon accounting lets SMEs showcase commitment through certified low-carbon products and services.
  • Cost savings: Monitoring energy consumption and emissions helps SMEs identify operational inefficiencies, enabling targeted reductions that cut costs.

As stakeholders demand climate action, carbon accounting transitions SMEs securely into a net-zero economy.

Carbon Accounting Scope 1, 2, and 3: A Primer

Carbon accounting categorises emissions into three scopes:

  • Scope 1 covers direct emissions from company-owned and controlled resources like vehicles and equipment.
  • Scope 2 accounts for indirect emissions from purchased electricity and heating.
  • Scope 3 includes other indirect emissions across the value chain - from raw material sourcing to product use and disposal.

While scopes 1 and 2 are mandatory, reporting scope 3 emissions demonstrates leadership. Robust carbon accounting incorporates all three scopes into environmental strategy.

Evaluating Your Carbon Accounting Readiness

Effective carbon emissions monitoring relies on robust data collection and reporting procedures. SMEs can assess readiness by examining:

  • Data availability: What emissions data is currently tracked? Where are the gaps?
  • Accounting expertise: Does the SME have skilled sustainability personnel to manage accounting practices?
  • Technological capabilities: Are processes digitised to streamline data collection? Do tools integrate emissions accounting?
  • Reporting structure: How are emissions reports compiled? Who communicates insights to leadership and stakeholders?

Evaluating these organisational capabilities identifies opportunities to implement accurate, comprehensive carbon accounting programs.

This covers the essentials of carbon emissions accounting for SMEs - understanding its relevance, scope, and readiness needs. With the right foundations, SMEs can seamlessly track and benefit from their sustainability metrics.

What is the difference between GHG accounting and carbon accounting?

Carbon accounting and greenhouse gas (GHG) accounting are closely related concepts in emissions reporting. While they share similarities, there can sometimes be some key differences:

  • Carbon accounting can sometimes only measure carbon dioxide (CO2) emissions from business operations and the supply chain. Whilst it usually does include other Greenhouse Gases, it is worth checking whether it focuses solely on tracking CO2. Usually, units will be reported in CO2e (equivalents) if other GH gases are being tracked.
  • GHG accounting encompasses not just CO2, but all major greenhouse gases that contribute to climate change. This includes methane, nitrous oxide, hydrofluorocarbons, and more. So GHG accounting provides a more comprehensive view of overall emissions.

Both carbon and GHG accounting quantify emissions using globally recognised standards and methodologies. These help businesses understand their environmental impact, set reduction targets, and make strategic decisions to mitigate climate risks.

As stakeholder expectations grow around organisational sustainability, specialised software tools are emerging to automate the accounting process. This saves time and resources while ensuring consistency and accuracy.

With ESG performance now directly tied to investment decisions and profitability, tracking emissions through carbon and GHG accounting delivers tangible business value. It enables transparency into climate risks and opportunities.

Ultimately, whether focusing specifically on carbon or taking a broader GHG emissions view, rigorous accounting lays the foundation for science-based climate action.

What is the accounting standard for carbon?

The most widely used carbon accounting standard is the Greenhouse Gas (GHG) Protocol. Developed by the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD), the GHG Protocol provides comprehensive and robust guidelines for measuring and reporting greenhouse gas emissions.

Some key aspects of the GHG Protocol standard include:

  • Defining scopes - Emissions are categorised into three scopes based on the source. Scope 1 covers direct emissions, Scope 2 covers indirect emissions from purchased energy, and Scope 3 includes value chain emissions.
  • Setting organisational boundaries - The standard provides guidance on determining which operations to include when accounting for emissions. This is based on concepts like financial control, equity share, and operational control.
  • Quantification methods - Detailed methods are provided for calculating emissions from various sources and activities. This includes guidance on emission factors, global warming potentials, and more.
  • Reporting principles - Principles like relevance, completeness, consistency, transparency and accuracy help ensure high-quality reporting and meaningful comparisons over time.

By adhering to such a widely adopted international carbon accounting standard, companies can effectively measure their carbon footprint, identify reduction opportunities, and benchmark performance. The GHG Protocol also enables credible public reporting and effective stakeholder engagement.

Overall, its comprehensive framework, flexible approach and focus on pragmatic solutions has made the GHG Protocol the most widely used emissions accounting standard globally.

How do I account for GHG emissions?

The spend-based method offers a straightforward approach to estimate a company's greenhouse gas (GHG) emissions. This involves multiplying the financial value of purchased goods and services by emissions factors linked to those purchases.

For example, $1,000 spent on air travel may equate to 2 tonnes of carbon dioxide emissions based on commercial airline emissions factors. By tallying expenditure across the supply chain and applying relevant factors, organisations can derive a reasonable estimate of overall GHG output.

The spend-based technique simplifies data collection and analysis. However, it lacks accuracy compared to primary data methods that directly measure emissions levels. Despite limitations, this method allows SMEs to rapidly benchmark current emissions, identify hotspots for reductions, and track performance over time. Paired with selective direct measurements, it provides a solid starting point for comprehensive carbon accounting.

SMEs keen to understand their GHG footprint can adopt a phased approach:

  • Phase 1: Spend-based emissions estimate
  • Phase 2: Incorporate measured data for key emission sources
  • Phase 3: Expand measured data coverage across all major sources

This pragmatic strategy allows SMEs to balance costs, complexity and accuracy based on evolving business needs and climate action commitments.

What is a carbon credit in accounting?

Carbon credits, also known as carbon offsets, are an important component of carbon emissions accounting. At a basic level, they represent permission for a company to emit a certain amount of carbon dioxide or other greenhouse gases.

How carbon credits work

A carbon credit permits a company to emit one metric ton of carbon dioxide equivalent (CO2e). By purchasing credits, a company can offset their own emissions in order to meet reduction targets or achieve carbon neutrality. There are two main ways companies can acquire carbon credits:

  • Cap and trade programs: Governments set an overall emissions limit, require companies to acquire credits for each ton of emissions they produce, and allow companies to trade credits on an open market.
  • Voluntary offset programs: Companies directly fund projects like renewable energy or reforestation. In exchange, they receive credits to offset their emissions. The projects must meet strict criteria to ensure reductions are real and verifiable.

Carbon credits provide flexibility for companies working to lower emissions. They also give financial incentives to projects actively removing carbon dioxide from the atmosphere. Overall, carbon credits are an integral tool for tracking and motivating decarbonization both on a regulatory and voluntary basis.


Crafting Your SME's Carbon Emissions Inventory

Creating an accurate carbon emissions inventory is an essential first step for SMEs seeking to understand, track, and reduce their climate impact. By categorising emissions sources and quantifying greenhouse gas outputs, SMEs build a foundation for strategic carbon accounting and reporting.

This section will explore practical methods for SME professionals to compile a comprehensive emissions inventory.

Selecting Carbon Accounting Tools for SMEs

SMEs need carbon accounting solutions catered to their unique size and resources. When evaluating software, consider these SME-friendly capabilities:

  • User-friendly interface: Seek simple, intuitive tools allowing non-experts to operate the software independently. Complex platforms with steep learning curves can overwhelm small teams.
  • Flexible tracking: Customisable carbon calculators that adapt as your business evolves provide reliable long-term value.
  • Automated data collection: Prioritise tools that integrate with your existing systems to auto-compile emissions data. Eliminating manual inputs saves time for small teams with limited bandwidth.
  • Collaboration features: Allow stakeholders like suppliers or clients to contribute emissions data for more complete carbon accounting.

Choosing software with these SME-tailored traits simplifies carbon accounting for resource-constrained teams.

Gathering Data for Scope 1 and 2 Emissions

Per the Greenhouse Gas (GHG) Protocol, a company's emissions are categorised into three "scopes":

  • Scope 1: Direct greenhouse gas emissions from sources owned or controlled by the company. Examples: on-site fuel combustion for boilers, fleet vehicle fuel usage, fugitive refrigerant leaks.
  • Scope 2: Indirect GHG emissions from purchased electricity consumed by the company.
  • Scope 3: All other indirect emissions from activities in the company's value chain.

For SMEs just starting carbon accounting, aim to quantify Scope 1 and Scope 2 emissions first as these directly controlled sources are easiest to track.

Collecting Scope 1 Data

  • Document fuel consumption for owned vehicles and equipment.
  • Record refrigerant recharges for chillers and A/C systems.
  • Note natural gas, propane, and fuel oil usage.

Compiling Scope 2 Stats

  • Gather monthly electricity bills detailing kWh consumption.
  • Confirm if utilities source renewable energy by requesting recent fuel mix reports.
  • Calculate location-based and market-based emissions using appropriate emission factors.

Assembling this energy and fuel consumption data builds a solid baseline to evaluate operations, set goals, and monitor progress lowering Scope 1 and 2 climate impacts over time.

Calculating Scope 3 Emissions: Indirect Supply Chain Impacts

For small teams, estimating complete corporate Scope 3 emissions poses challenges as SMEs often lack visibility into complex supplier and customer value chains. However, even basic Scope 3 screening assessments can uncover "hot spots" to address for material emissions reductions.

Common Scope 3 categories relevant for SMEs:

  • Employee commuting and business travel
  • Waste disposal and water consumption
  • Purchased goods, materials, and services
  • Transportation and distribution (upstream/downstream)

To approximate Scope 3 outputs, SMEs can:

  • Conduct surveys: Gather staff transportation habits. Estimate distances for common material sourcing locales or product shipping routes.
  • Request data: Ask key suppliers and service providers to share carbon footprints for their offerings.
  • Apply industry averages: Multiply a relevant emissions factor per unit of production, sales, or spend.

While rough Scope 3 estimates still bring value, SMEs can achieve much greater precision by partnering across their value chains to promote transparency through mutual data sharing. This fosters sustainability progress industry-wide.

With Scope 1, 2, and 3 emissions quantified as able, SME professionals have assembled their first comprehensive corporate carbon inventory. Now equipped with a emissions baseline and armed with methods to regularly update the inventory, SMEs can implement sound strategies to gradually reduce their climate impacts over time.

Analysing and Compiling Your Carbon Accounting Report

Interpreting your emissions data is crucial for strategic planning and communication. Discover how to turn your findings into a comprehensive carbon accounting report.

Assessing feasibility factors like cost, disruption, and resource requirements can further guide strategic decisions on reduction opportunities.

Benchmarking Success: Setting and Achieving Emissions Targets

With focused emission mitigation initiatives defined from your carbon accounting analysis, it’s time to set tangible reduction goals. Target setting necessitates:

  • Establishing a baseline emissions year - Pick a reference period to benchmark future progress against, often your latest 12 months of finalized carbon accounting.
  • Defining an emissions boundary - Specify which parts of your business and associated scopes will be covered in your target.
  • Selecting a target timeline - Common options include annual targets or longer-range goals by 2025, 2030 or aligned to net zero.
  • Choosing an ambitious but achievable target - Research suggests SMEs slash emissions 25-30% below baseline by 2030. Consider your budget, operational capacity and reduction roadmaps when calculating potential.
  • Formalising the target - Codify the goal through official sustainability policies, carbon pledges, ESG reporting and stakeholder communications.

Once declared, revisit your target at least annually using carbon emissions accounting techniques like EcoHedge. Update stakeholders on progress through sustainability reports. If significantly behind schedule, reassess reduction plans and timelines. Incrementally raising ambition over time is key to driving continual improvement.

Best Practices for External Reporting on Carbon Emissions

With reliable emissions data in hand plus defined targets benchmarking performance, SMEs must strategically report out findings. Your carbon accounting presents a pivotal opportunity to boost reputation and transparency. But without clear communication of methodology, data accuracy, reduction plans and target tracking, credibility suffers.

Follow these best practices when compiling your report:

  • Lead with strategy - Summarise organisational and sustainability context upfront to demonstrate intentionality.
  • Spotlight data reliability - Note methodologies used and verification status to prove data rigour.
  • Illustrate through visuals - Charts depicting historical emissions, target tracking and projections tell a powerful story.
  • Contextualise figures - Compare benchmarks like emissions per full-time employee against industry averages.
  • Own unflattering outcomes - If missing targets, explain factors and course corrective actions without excuses.
  • Close with next steps - End each report with concrete plans to continue progress.

Carbon accounting reports require planning and finesse. But methodical, insightful communication of your sustainability journey builds stakeholder trust and motivates ongoing emission mitigation.

Actionable Strategies for Carbon Emission Reductions in SMEs

Explore tangible strategies that SMEs can implement to reduce their carbon emissions, enhancing both environmental and economic performance.

Implementing Cost-Effective Emission Reductions

There are many low-cost, high-impact actions SMEs can take to immediately reduce their carbon emissions:

The incentives make sound environmental and financial sense for SMEs on the decarbonization journey. Wise use of such programs allows faster realization of emission reduction goals.

Maintaining Momentum: Monitoring Carbon Emissions Over Time

Consistent tracking and analysis of emissions is key to continuous improvement. As SMEs embark on their net-zero journey, implementing robust systems to monitor their carbon footprint over time is essential. This allows them to identify improvement opportunities, demonstrate progress to stakeholders, and ensure they stay on track to meet their climate commitments.

Building Sustainable Data Collection Systems

To enable consistent emissions monitoring, SMEs first need to establish strong data collection processes. This involves determining key data sources, collection frequency, roles and responsibilities, data integrity checks, and documentation. Critical areas to track data include energy, waste, transportation, purchased goods/services, and more.

Ideally, SMEs should invest in carbon accounting software like EcoHedge to automatically pull data from various business systems. For example, utility bills can populate energy consumption figures, mileage logs can track transportation emissions, etc. This eliminates manual data entry and provides real-time visibility into the carbon footprint.

If the software isn't an option, SMEs can still implement manual data-gathering workflows, e.g. designated staff compiling relevant data into spreadsheets. The key is having standardised processes to ensure data accuracy over long periods. Consistent tracking allows meaningful comparison to historical baselines.

Linking Carbon Footprint with Financial Performance

Beyond environmental impact, financial incentives also motivate SMEs to monitor their emissions. Studies show firms that manage their carbon proactively enjoy faster growth, higher profitability, and easier access to capital.

Integrating carbon accounting data with financial reporting provides a comprehensive view of business performance. For example, calculating emissions per unit of production quantifies the relationship between carbon footprint and output volume. This allows modelling emissions under different business scenarios to make strategic decisions.

With integrated reporting, SMEs can also demonstrate lower operating costs from sustainability initiatives like energy efficiency. Reduced energy consumption has a direct, measurable impact on spend. Tracking this helps build the business case for further carbon reduction investments.

Projecting and Preparing for Future Emissions

Leveraging their emissions data, SMEs can forecast future carbon footprints based on projected growth. Simple extrapolation methods using historical data can provide first-order estimates. More advanced models factoring additional variables may yield greater precision.

Projections enable SMEs to set science-based targets aligned with desired decarbonisation trajectories. If forecasted emissions exceed goals, mitigation plans can be activated early on. For example, switching suppliers, changing product materials, or investing in renewable energy projects.

As regulatory regimes and stakeholder expectations rapidly evolve, projections also help SMEs identify transition risks and opportunities. Ultimately, monitoring emissions consistently over time provides the foundation for SMEs to make informed, strategic decisions to sustainably manage their carbon footprint.
