As U.S. environmental commodity markets expand and become central to corporate sustainability strategies, a critical challenge emerges: ensuring the credibility of environmental claims. The rising tide of "greenwashing", where companies make unsubstantiated or misleading environmental assertions, threatens to undermine trust, distort genuine decarbonization efforts, and erode the very foundation of these markets. For businesses seeking to make a verifiable impact, understanding and addressing issues like "double counting" and "non-additionality" is paramount. This article provides a strategic guide to navigating these concerns, emphasizing the indispensable role of transparency, robust verification, and scientific substantiation in building lasting credibility.

The Challenge of Greenwashing

Greenwashing refers to the practice of making unsubstantiated or false environmental claims to appear environmentally friendly. This issue is pervasive; studies indicate that a significant percentage of environmental claims are potentially misleading or lack verifiable evidence. Such practices not only deceive consumers and investors but also undermine the integrity of clean energy programs and distort greenhouse gas (GHG) reduction goals. Regulatory bodies, such as the EU Commission with its Green Claims Directive, are increasingly stepping in to combat greenwashing by mandating scientific substantiation and independent third-party verification for environmental claims.  

Key Integrity Issues: Double Counting and Non-Additionality

The integrity of environmental commodity markets hinges on preventing two critical issues:

Double Counting

"Double counting" occurs when the environmental attributes associated with a single unit of renewable energy generation or a carbon credit are claimed or tallied multiple times. This can manifest in several ways:  

• Duplicate Registrations: A generator is registered in multiple Energy Attribute Certificate (EAC) registries, leading to duplicate claims.  
• Conflicting Attribution: A market operator attributes renewable energy to a state or utility without involving RECs, while the corresponding REC is simultaneously sold and claimed by another entity. For example, a wind farm's electricity might be attributed to California for emissions compliance, while its REC is sold to a utility in Colorado, leading both to claim the same renewable energy.  

The implications of double counting are severe: it undermines the credibility of clean energy programs, distorts GHG reduction goals by leading to inaccurate emissions reports, impacts Renewable Portfolio Standards (RPS) targets and other programs like California's LCFS, and can even jeopardize eligibility for federal subsidies, such as the IRA's 45V hydrogen production tax credit.  

Non-Additionality

"Non-additionality" refers to the generation of credits from projects that would have occurred anyway, without the specific policy intervention or market incentive. In essence, the "extra good" claimed is not truly additional to a defined baseline scenario. This issue is a leading source of concern in offset programs because it means the environmental benefit is not real or incremental. Non-additionality reduces stakeholder confidence in tradable environmental instruments, undermines both environmental and economic gains, and can erode political support for environmental markets in general.  

Ensuring Credibility: Pillars of Integrity

To counteract these challenges and maintain market integrity, transparency, robust verification, and scientific substantiation are critical:

Transparency

Transparency is crucial for building trust and directly preventing issues like double counting and non-additionality. It involves the clear explication of how credits are generated, traded, and retired. Key mechanisms include:  

• Public Carbon Registries: These platforms serve as verifiable databases that list projects, issued credits, ownership, and retirement records, accessible to all market participants.  
• Standardized Reporting: Project developers must adhere to specific rules and methodologies for quantifying emission reductions, with documentation made publicly available.  
• Transaction Data: Information on the volume of credits traded, transaction dates, and identities of buyers and sellers (where appropriate) contributes to market openness.  

Robust Verification

Verification entails a systematic and independent assessment to ensure that environmental statements are accurate, truthful, and compliant with established standards and criteria, based on historical data. Independent third-party verification is often a prerequisite for green claims to be considered credible. This external validation adds a layer of objectivity, reduces skepticism, and mitigates the risks of lawsuits, regulatory scrutiny, and reputational damage by preventing misleading information and unfair commercial practices.  

Scientific Substantiation

Environmental claims must be underpinned by robust scientific evidence, supported by verifiable data and research. This includes a comprehensive consideration of all significant environmental impacts throughout a product's or service's life cycle. For example, a claim of "CO₂-neutral supply chain" requires transparent demonstration of certified CO₂ offsetting projects that meet strict requirements.  

Strategic Guidance for Companies

To ensure sustainability claims are robust, transparent, and genuinely contribute to new environmental benefits, companies should:

• Make Truthful and Accurate Claims: Avoid exaggeration or misleading information, ensuring claims accurately represent environmental performance.  
• Provide Substantiation: Back claims with verifiable evidence and transparent methodologies.  
• Ensure Relevance and Specificity: Claims should be relevant to the product/service, have a meaningful impact, and avoid generic terms without specific details.  
• Adopt Life Cycle Thinking: Consider the entire life cycle of the product or service, from raw material extraction to end-of-life.  
• Adhere to Standards and Regulations: Comply with recognized environmental standards, benchmarks, and relevant laws.  
• Ensure Exclusive Claims: For environmental commodities, the buyer must have an exclusive claim supported by a tracking instrument (e.g., EACs, Carbon Credits) that are retired in a certified registry to prevent other claims on the same attributes. Contracts should explicitly clarify exclusive rights and that attributes are not used for other regulatory requirements.  
• Conduct Due Diligence: Thoroughly vet environmental commodity providers, verifying their claims regarding project additionality and environmental impact.  

‍

The integrity of environmental commodity markets is not merely an ethical consideration but a fundamental driver of financial value and market liquidity. Issues such as double counting and non-additionality undermine confidence and distort climate action. Conversely, transparency, rigorous verification, and scientific substantiation are vital for building trust and ensuring environmental integrity. As regulatory focus on market integrity intensifies, legitimate market participants stand to benefit from a more reliable and trustworthy environment. For businesses like AFS Commodities, investing in and trading instruments with robust verification, transparent registries, and clear additionality criteria is crucial for mitigating both reputational and financial risks, positioning them at the forefront of a credible and impactful green economy.
