Why Data Quality is Critical to Carbon Accounting
Data for carbon accounting needs to be clean, accurate and reliable. This article takes a deep dive into why C-level executives need to ensure quality carbon accounting data.

In the race toward net-zero, enterprises face growing pressure from regulators, investors, customers, and employees to accurately measure, manage, and report their carbon emissions. But amid the buzz around ESG strategies, carbon offsets, and green innovation, one foundational element often gets overlooked: data quality.
Carbon accounting relies on a vast, complex network of data points. Each must be complete, consistent, and reliable. For C-level executives responsible for corporate strategy, compliance, and risk, poor data quality isn't just a technical nuisance. It's a strategic liability that can derail sustainability goals, distort financial decisions, and expose the business to reputational, regulatory, and operational risk.
This article unpacks the crucial role that data quality plays in carbon accounting, explores the risks of getting it wrong, and outlines how large organizations can build a robust data foundation to enable accurate, audit-ready emissions reporting.
Carbon accounting is the process of quantifying the greenhouse gas (GHG) emissions that a business produces directly or indirectly across Scope 1, 2, and 3 emissions categories.
Each scope comes with unique data challenges, from granular fuel consumption logs to supplier-reported emissions and third-party estimates.
According to a 2023 PwC survey, 82% of CEOs say they’ve taken steps to reduce their carbon footprint, yet only 34% trust the accuracy of their emissions data.
This trust gap has major implications.
If emissions data is incorrect, outdated, or duplicated, the financial and reputational consequences can be severe.
1. Data Volume and Variety
Large enterprises operate across multiple geographies, business units, and facilities. Emissions data may span:
The volume and heterogeneity of these inputs make it easy for errors, gaps, and inconsistencies to arise.
2. Lack of Standardization
Carbon data is notoriously unstructured. One business unit may report electricity in kilowatt-hours, another in megajoules. Emissions factors may vary by country, industry, or time period. Without standardized formats and measurement units, aggregation becomes a nightmare.
3. Manual Data Handling
Many organizations still rely on spreadsheets or ad hoc tools to gather and manage emissions data. This leads to human error, duplication, version control issues, and limited traceability.
For the C-suite, substandard emissions data poses significant risks that extend far beyond sustainability reporting:
1. Reputational Damage
If inaccurate data leads to overstated reductions or greenwashing claims, public backlash can be swift and severe. In the age of social media and activist investors, misreporting carbon data, whether intentional or not, can trigger brand erosion and shareholder distrust.
2. Regulatory Non-Compliance
New and upcoming regulations are raising the bar for data accuracy. Under the EU CSRD, for example, emissions disclosures must be auditable and verifiable. Failure to comply can result in penalties, litigation, or exclusion from capital markets.
3. Strategic Misalignment
Carbon data is increasingly used to inform key decisions, from capex allocation to supplier onboarding and product design. If the data is wrong, the business may pursue inefficient or ineffective decarbonization strategies, wasting resources and delaying impact.
4. Financial Penalties
As carbon pricing expands globally, incorrect emissions figures can lead to overpayment or underpayment of carbon taxes, exposing the company to financial loss or future audits and corrections.
5. Missed Opportunities
Poor data quality can obscure opportunities to optimize emissions hotspots. Without granular, trusted data, a business may not identify which facility, fleet segment, or supplier is driving the highest Scope 3 impact.
Improving carbon data quality is not a quick fix. It requires executive sponsorship, cross-functional coordination, and smart investments. Below is a high-level roadmap tailored for C-level leaders seeking to build a scalable carbon data program.
1. Appoint a Data Stewardship Function for Sustainability
Establish a cross-functional sustainability data office (SDO) that includes representatives from finance, operations, IT, procurement, and ESG. This team should:
2. Map the Data Landscape
Inventory all internal and external data sources feeding into your carbon accounting system. Identify:
3. Integrate with Master Data Management (MDM)
Link carbon data to your enterprise’s master data, including facilities, assets, suppliers, products, and regions. This enables:
4. Automate Data Collection and Validation
Leverage digital tools to automate and streamline:
Platforms such as sustainability management software (SMS) or carbon data hubs can integrate with your ERP, IoT, and supplier systems for seamless, real-time data flow.
5. Embed Quality Controls in Carbon Workflows
Apply data quality checks at each stage of your carbon accounting process:
6. Prioritize Supplier Data Engagement
Scope 3 emissions often make up over 70% of a company’s carbon footprint, yet supplier data is the least controlled. C-level support is needed to:
Supplier data collaboration is not just ESG. It is enterprise risk management.
7. Report with Confidence
With trusted data, your ESG and finance teams can:
Sustainability is no longer a siloed initiative. It is a C-level accountability. Whether you are a CFO overseeing financial disclosures, a COO optimizing operations, or a Chief Sustainability Officer tasked with delivering on ESG promises, you depend on high-quality carbon data.
Investing in carbon data governance:
More importantly, it shows that your sustainability claims are grounded in fact, not fiction.
Carbon accounting is only as good as the data behind it. In a world of growing regulatory pressure and environmental scrutiny, poor data quality is not just an IT problem. It is a business risk.
Enterprises that treat carbon data with the same rigor as financial data will be better equipped to lead in the low-carbon economy. That starts with the C-suite championing investment in data infrastructure, governance, and automation to ensure every emissions figure is trustworthy, timely, and transparent.
Because when the numbers matter this much, data quality becomes a strategic advantage.
