RSB – Roundtable on Sustainable Biomaterials is a global, multi-stakeholder organisation dedicated to driving the truly sustainable development of the bioeconomy. Frequently recognised as an industry leader in supply chain sustainability, RSB applies its best-in-class sustainability framework across sectors including aviation, chemicals, materials, and shipping.
Our small, dedicated team operates remotely from countries around the world, working collaboratively with a diverse base of member organisations, industry partners, and policymakers. For more information, please visit www.rsb.org.
RSB now invites eligible organisations and individuals to indicate their interest. Throughout this document, “Consultant” refers to both organisations and individuals. RSB is building a pre-approved External Consultant Roster: a qualified pool of selected specialists and organisations that will be called upon for project-based work over the next 2 years.
Consultants accepted onto the roster will complete a brief onboarding process to become familiar with RSB’s systems, ways of delivering services, and sustainability framework. When a specific project or capacity gap emerges, RSB will contact roster members whose profile best matches the assignment, share a defined scope of work, and invite them to submit a proposal.
Inclusion on the roster is an expression of readiness and fit and not a guarantee of immediate work or remuneration.
The Power-to-X (PtX) & Advanced Biofuels Consultant will provide technical research, policy analysis and value-chain expertise on renewable hydrogen, PtX fuels and sustainable aviation fuel (SAF) topics, to support RSB's work on PtX fuels, advanced biofuels, SAF policy, certification readiness, and related grant-funded programmes. Estimated time investment and budget are to be confirmed based on the agreed scope, daily rate, and project needs.
Specific deliverables, estimated time input, and project duration will be clarified in the Terms of Reference (TOR) issued to shortlisted roster members when a project need is identified. Indicative output types may include, but are not limited to:
