Clayton Utz outlines new TNFD disclosure guidance requiring alternative fuel and bioenergy sectors to report on nature and biodiversity impacts.

Overview of TNFD Alternative Fuels Reporting Framework

The Taskforce on Nature-related Financial Disclosures released sector-specific guidance for alternative fuels in late June 2026, and on 24 July 2026, Australian law firm Clayton Utz published a detailed analysis of what this means for organisations involved in bioenergy, green hydrogen, and synthetic fuels. The guidance introduces a structured disclosure test that goes well beyond carbon accounting, requiring producers, purchasers, and downstream users of alternative fuels to assess and report on their direct dependencies and material impacts on land, freshwater systems, and biodiversity. This represents a fundamental shift in how the environmental credentials of energy transition projects are evaluated, assessed, and disclosed to the market.

Until now, many project proponents and corporate buyers in the alternative fuels sector have leaned heavily on carbon-reduction metrics as the primary measure of environmental performance. A project that displaced fossil fuels was broadly treated as a positive environmental outcome, and the ecological footprint of the production process itself received comparatively little attention. The TNFD sector-specific guidance closes that gap by establishing that a favourable carbon narrative does not, by itself, constitute adequate disclosure of nature-related financial risks. Organisations are now expected to work through a structured four-phase assessment process and disclose findings on a comply-or-explain basis.

For environmental professionals advising developers, energy companies, financiers, and downstream buyers in Australia, this guidance changes the scope of what an adequate environmental assessment looks like for transition energy projects. It also raises significant questions about greenwashing liability under existing Australian corporations law, particularly where disclosure obligations intersect with representations made to investors, counterparties, or regulators. The practical consequences extend from project feasibility through to transaction due diligence, supply chain auditing, and ongoing corporate reporting.

Key details of the TNFD alternative fuels disclosure framework

The TNFD sector-specific guidance for alternative fuels structures its requirements around the LEAP framework: Locate, Evaluate, Assess, and Prepare. This four-phase approach requires organisations to first locate their interfaces with nature across their operations and value chains, evaluate their dependencies and impacts on natural assets, assess the material nature-related risks and opportunities that arise from those dependencies and impacts, and then prepare to respond through integrated disclosure and governance. The LEAP approach is not aspirational guidance. It is the methodological spine against which disclosures are expected to be framed, and on which external scrutiny will focus.

For bioenergy projects specifically, the guidance introduces traceability requirements that are more granular than those previously applied under most voluntary sustainability frameworks. Primary biomass feedstocks must be traced back to the specific farm, plantation, or forest-sourcing area. This is farm-level or plantation-level traceability, not broad regional or country-of-origin certification. For waste and residue feedstocks, point-of-origin traceability is required. Critically, classifying a material as waste does not exempt it from nature-impact disclosure requirements. The underlying ecological pressures associated with that waste stream, including land-use patterns, catchment health, and biodiversity interactions at the source, remain in scope for assessment and disclosure.

For green hydrogen and synthetic fuel projects, the guidance identifies a distinct set of physical pressures that must be evaluated. These include land-use competition from the renewable energy infrastructure required to power electrolysis or fuel synthesis, water stress at the catchment level arising from the water volumes consumed in hydrogen production, mineral extraction impacts associated with electrolysers and related equipment, potential hydrogen leakage to the atmosphere, and the management and disposal of high-salinity brine discharge from water treatment processes. The brine discharge issue in particular is one that has received limited attention in Australian project approvals to date, and it carries direct implications for receiving water quality assessments and site-specific impact characterisation.

Downstream users of alternative fuels are explicitly captured by the guidance. Airlines, shipping companies, and electricity utilities that purchase bioenergy, green hydrogen, or synthetic fuels are expected to disclose core sector metrics for material nature-related issues associated with the fuels they buy, even where they have no operational control over the production process. This value-chain liability is a significant expansion of disclosure scope. It means that a purchaser cannot discharge its nature-related disclosure obligations simply by selecting a certified or accredited fuel supplier. The purchaser must engage with the nature-related performance data of its supply chain and report on it as part of its own disclosure obligations.

Australian context: TNFD guidance, Corporations Act obligations, and mandatory sustainability reporting

Australia is in the process of implementing mandatory climate-related financial disclosure requirements under the Corporations Act 2001 (Cth), with phased commencement from 2025 onward applying to large listed entities, financial institutions, and certain other reporting entities. The legislative framework for climate disclosure is already in motion, and the trajectory toward mandatory nature-related disclosure is increasingly clear. The TNFD framework, while currently voluntary in Australia, operates as the international reference standard against which both voluntary and mandatory sustainability disclosures are benchmarked.
