Lower your fleet emissions with a drop-in diesel alternative. Explore Dieselite.

Argent Energy supplies certified, waste‑based biodiesel that enables immediate, measurable greenhouse gas (GHG) reduction of around 85-90% when used as an alternative to fossil fuel diesel.  Produced entirely from certified end-of-life waste feedstocks, our second-generation fuels provide an alternative to fossil diesel for fleets, local authorities and large enterprises seeking to reduce emissions now.

With full supply‑chain traceability, independently verified sustainability certifications and reliable emissions reporting, we support customers with robust data for ESG reporting, regulatory compliance and carbon reduction planning.

A renewable alternative to fossil diesel

Not all biodiesel delivers the same environmental outcomes and Argent’s sustainability model is built on one clear principle: only certified, waste‑based feedstocks with full traceability and independently verified sustainability credentials.

Our biodiesel is produced from 100 per cent waste-derived materials, ensuring:

  • No competition with food or animal feed
  • No purpose‑grown crops
  • No indirect land‑use change
  • Typically lower lifecycle emissions than many crop‑based biofuel alternatives

By using waste streams that would otherwise require disposal, Argent converts unavoidable waste into a into a second-generation fuel, supporting circular economy principles while helping displace fossil diesel.

Measurable carbon savings (Well-to-wheels)

We know that sustainability claims must be measurable to be credible so we calculate greenhouse gas savings using full lifecycle (well‑to‑wheels) analysis, in line with UK and international reporting standards.

This includes emissions from:

  • Feedstock origin and collection
  • Transport logistics
  • Fuel production and refining
  • Distribution

Our comprehensive approach ensures carbon savings reflect the true environmental impact. Depending on feedstock origin and supply chain characteristics, Argent’s waste-based biodiesel can deliver lifecycle greenhouse gas savings of up to 90 per cent compared with fossil diesel on a well-to-wheels basis. It also means our customers have carbon data that is quantifiable and verifiable, supporting Scope 1 fuel-use reporting and wider Scope 3 reporting requirements where applicable.

Full traceability and transparency

Traceability is fundamental to sustainable fuels and is central to Argent’s approach.

All waste-based feedstocks used in Argent’s biodiesel are traceable through certified supply chains,  supported by verified feedstock documentation and auditable sustainability records.

Argent provides customers with audit‑ready sustainability data and supporting documentation to help substantiate environmental claims.

This level of transparency directly supports:

  • ESG and sustainability reporting
  • Carbon reduction plans
  • Public sector procurement requirements
  • Internal governance and risk management

Dieselite – Immediate Decarbonisation for Diesel Fleets

For organisations looking to reduce emissions from diesel vehicles today, Dieselite offers a practical lower-carbon fuel solution. By increasing the proportion of Argent’s second-generation, waste-based biodiesel and displacing fossil diesel in the blend, Dieselite helps reduce lifecycle greenhouse gas emissions without requiring vehicle modifications or infrastructure changes.

Containing between 10 and 30 per cent waste-based biodiesel, compared with less than seven per cent in standard diesel, Dieselite enables organisations to begin reducing emissions immediately while longer-term technologies such as electrification continue to develop. Key benefits:

  • Affordable carbon reduction
  • Higher renewable fuel content (10–30 per cent vs standard diesel <seven per cent)
  • Produced using Argent’s second-generation biodiesel made from 100% waste-derived feedstocks
  • Drop‑in solution requiring no engine or infrastructure changes
  • Compatible with existing diesel vehicles
  • Lifecycle greenhouse gas savings ranging from 10% to 27%, depending on blend level chosen
  • Supported by verified emissions reporting and sustainability declarations

Dieselite proves that fleet decarbonisation doesn’t have to wait for future technology and steps can start today. To learn more about Dieselite, the cost-effective decarbonisation solution, visit our dedicated page.

Emissions reporting and customer assurance

Argent goes beyond fuel supply by providing customers with the data required to demonstrate quantified emissions reductions.  This includes quantified CO₂ savings per tonne of fuel supplied, quarterly renewable fuel declarations, and verified emissions savings aligned with regulatory guidance.

Customers receive Quarterly Renewable Fuel Declarations detailing:

  • Feedstock origin and sustainability classification
  • Certification references
  • Lifecycle emissions values
  • GHG savings vs fossil diesel baseline

The report enables defensible, audit-ready carbon reporting for ESG disclosures, public sector reporting, corporate sustainability statements, and supply‑chain reporting obligations.

Supporting your decarbonisation strategy

For many operators, waste‑based biodiesel can complement electrification and other decarbonisation technologies by delivering emissions reductions from existing diesel assets today.  We support organisations at different stages of their decarbonisation journey by:

  • Delivering immediate emissions reduction where electrification is not yet feasible
  • Helping meet near‑term carbon reduction targets
  • Reducing emissions from existing assets
  • Supporting supply‑chain sustainability requirements

For hard‑to‑abate sectors and high‑utilisation fleets, renewable fuel solutions provide real impact today, while longer‑term technologies scale.
