Carbon Direct has released a new framework designed to help voluntary market buyers evaluate and procure high-quality low-carbon fuels (LCFs), as demand for alternative fuels grows across hard-to-abate sectors.
The newly published Criteria for High-Quality Low Carbon Fuels consolidates a range of sustainability, accounting, and sourcing considerations into a single framework intended to guide procurement decisions in an increasingly complex market.
According to Carbon Direct, the guidance addresses a gap in the current landscape, where buyers must navigate multiple certification schemes, regulatory programs, and quality standards that often cover only portions of the supply chain or environmental impact profile.
“The voluntary low-carbon fuels market is complex, crowded, and moving fast,” said Rohan Raman, Senior Hybrid Decarbonization Engineer at Carbon Direct. “The Criteria give buyers something no single existing certification provides: a unified, comprehensive set of quality principles that can be used to assess the sustainability of their procurement.”
The release comes as voluntary demand for low-carbon fuels continues to expand, particularly in sectors such as aviation, shipping, and heavy industry. However, differing regional standards, evolving methodologies, and limited supply chain transparency have made it difficult for buyers to assess the environmental integrity of fuel purchases.
Six principles for evaluating fuel quality
The framework is built around six core principles that Carbon Direct says should underpin high-quality low-carbon fuel production and procurement.
These include avoiding social and environmental harms, preventing negative ecological impacts, applying comprehensive and conservative carbon accounting practices, demonstrating additionality, ensuring sustainable and transparent feedstock sourcing, and assessing potential leakage effects.
The guidance places particular emphasis on accounting for indirect impacts that can be difficult to measure, including land-use change, feedstock displacement, and broader market effects. Producers are also encouraged to demonstrate that voluntary market revenues are enabling emissions reductions or fuel production that would not otherwise occur.
In addition, the criteria call for traceable supply chains, protection of Indigenous rights and local communities, compliance with international labor standards, and transparent disclosure of environmental risks.
Carbon Direct said the framework is intended to complement, rather than replace, existing certification systems by providing buyers with a consolidated reference point for due diligence and procurement decisions.
