evaluates supply chain companies on three principle criteria: Economic Viability, Scalability and Sustainability.

Ranking Criteria

The Carbon War Room has established Economic Viability, Scalability and Sustainability as the three principal criteria on which we, and an international team of experts, evaluate renewable jet fuel supply chain companies. The sub-criteria for each of these principal criteria are listed below with examples of some of the indicators used to determine sub-criteria scores.

Economic Viability

Cost of Production
Projected production costs over the near to mid-term. Greater weight is assigned to customer/market/third party-validated production cost figures.

Capital Intensity
Projected capital costs normalized for 100 million gallons (378,541,178 liters) per year output, and scale threshold for commercial viability. Lower capital intensity receives a higher score.

Market Risk
Competition/insulation from competitive markets for the company’s target and intermediate products (e.g. demand from food or cosmetic markets, demand for power generation, etc).


Technology Risk/Maturity
Stage and scale of technology demonstration relative to scale required for commercialisation; duration of operation at said scale; and third-party verification and validation of technology.

Demonstrates access to funding. Companies with strong capital partnerships and/or lower funding requirements rank higher.

Resource Constraints
Measure of agro-climatic and geographic constraints on water and suitable land production. Measure of potential feedstock volumes, taking into consideration potential logistical and market constraints.

Measure of yields as a function of inputs, and yields achievable per unit of land. Companies with greater yield potential and/or fewer geographic/feedstock constraints score higher.


Green House Gas Lifecycle Analysis (GHG LCA)
Measure of GHG reductions relative to fossil fuel baseline and degree to which LCA has been validated (e.g. peer-reviewed study, RSB calculation & audit, in-house study etc).

Sustainability Certification
Percentage of operations/products certified, and of the type of certification achieved. RSB certification is most desirable, then other multi-stakeholder standards (e.g. Bonsucro, RTRS, FSC etc), then industry or internally developed standards. Government mandated sustainability requirements (e.g. US RFSII, EU RED) are considered.

Food Security
Competition with food supply is undesirable, and a function of the edibility of feedstocks and competition with arable land.

Land Use Change
Degree to which high-carbon and/or biodiverse land is used directly or indirectly in company operations, and to which their land use impacts have been verified.

Fresh Water Impacts
Measure of fresh water use as a function of output, degree of water use in fresh-water sensitive areas, and any water quality impacts.

Stars & Updates

Companies are scored under each criterion and sub-criterion with one, two or three stars. These are relative scores, meaning the top one third of companies for a given criterion will be awarded three stars, the middle third will be awarded two stars, and so on. As companies, technologies, and the market evolve, the relative positions of each company under each criterion will shift accordingly.


In releasing a beta website with company rankings we are drawing initial conclusions based on rapidly changing market information. We invite: 1) input that updates or completes company/product information already collected; and 2) input regarding companies/products that we do not currently have. To be included in the database, please submit a request to

There are five possible reasons for a company not appearing in the rankings:

  1. Company did not rank top ten
  2. Company is too early in development to rank (i.e. pre-pilot plant)
  3. Organization declined to share data
  4. The rankings team was unable to contact company or find sufficient publicly available information to fill data gaps
  5. The company plays a role in the supply chain not conducive to side-by-side ranking comparisons (i.e. companies that license certain technologies to a number of fuel producers who were ranked)

If you have questions about which companies were ranked and what data was made publicly available, please contact
