RELX Environmental Challenge 2026: Clean Water, Sanitation, and Ocean Innovation Prizes

RELX Environmental Challenge 2026: Clean Water, Sanitation, and Ocean Innovation Prizes

If you build practical solutions for communities that struggle with safe water and sanitation, or if your idea strengthens ocean health and resilience, this is a clear, globally accessible challenge with straightforward entry terms and a transparent two-category prize structure.

The 2026 RELX Environmental Challenge continues a recurring program focused on real-world innovation in water, sanitation, and sustainability. In 2026, RELX announced that the prize model expands to two major awards of US$75,000 each: one for clean water or sanitation, and one for ocean innovation.

The challenge is not a typical grant program with multiple tranches and progress reporting. It is a competition with fixed entry windows, judging criteria, and final prize selection.

Key details at a glance

What the challenge is for (and what it is not)

At the core, this is a skills-and-idea competition aimed at solving clearly identified access and environmental problems. Official wording describes it as a “skill-based competition” where participants submit proposals that can advance access to safe, sustainable water and/or sanitation where access is at risk, and/or contribute to ocean health and marine ecosystem resilience.

What makes this cycle notable is the category split:

• Clean Water or Sanitation Prize (US$75,000): projects focused on safe water and sanitation outcomes.
• Ocean Prize (US$75,000): projects focused on ocean health, marine ecosystems, or ocean-based sustainability solutions.

The challenge page adds that projects should show practical applicability, define a real need, and generate impact tied to outcomes in health, education, equity, or human rights. The official rules add that projects are judged against hard criteria, including scalability, sustainability, innovation benchmark quality, stakeholder impact, and local/community engagement.

This is not primarily a small grant stream with multiple rounds and project budgets. It is a prize competition where each submission is judged as a full proposal package and compared against others in a public, standards-based process.

Official timeline and status check for this cycle

The 2026 application window is explicit and dated in the official material:

• Start: 09:00 GMT, 13 March 2026
• End: 23:59 GMT, 12 July 2026

For most applicants, this means the opportunity is currently usable and still open relative to the repository’s target date of 31 May 2026. After closing, the published sequence is shortlist discussion in or after August 2026, with winner announcements in or after October 2026.

Important timing detail:

• Entries outside the window are invalid, even if technically submitted through an issue.
• RELX site/server clocks govern timing.
• Submissions are not accepted if incomplete, malformed, late, or improperly submitted.

A major practical implication: plan backward from 12 July with a working buffer for draft review, eligibility checks, and possible last-minute technical fixes.

Eligibility map: who fits and who may be excluded

Confirmed eligibility

From the official rules:

1. Minimum age and account capacity

   • Applicants must be 21+ at entry time.
   • Must have access to internet and email during challenge and prize periods.

2. Applicant type

   • Individual applicants.
   • Teams of individuals.
   • Organisations (educational institutions, nonprofits, corporations).

3. Representation requirement

   • When applying as a group or on behalf of a team/organisation, the submitter must have authority to represent and distribute outcomes as needed.

4. Global eligibility with caveats

   • Subject to applicable laws in the applicant’s country.
   • RELX can verify eligibility and disqualify non-compliant entries.

5. Submission integrity

   • At most one entry per applicant or organisation.
   • Multi-entry via aliases/devices can lead to disqualification.

6. Who is usually excluded by rule design

   • RELX employees, affiliates’ employees, promotion agency personnel and immediate family/household members are excluded.

What to treat as not confirmed

• Whether some countries have local regulatory constraints on legal entity participation: this may vary and should be checked before submission.
• Whether all project budgets or legal structures are accepted (the official material gives strong general rules, not sector-specific exceptions).

If your idea relies on restricted legal status (school-led entity, foundation, youth body, government department), check those jurisdictional constraints before filing and keep proof documentation ready.

Application path and required deliverables

The RELX official site says the 2026 cycle is open to apply until 23:59 GMT on 12 July 2026 and points to official rules and an application platform. The rules are the governing source for submission integrity.

A conservative preparation flow that works well:

1) Pre-submission

• Read the official rules PDF in full and treat it as a contract.
• Decide category:
  • Clean water/sanitation
  • Ocean-related innovation
• Define problem statement in one sentence:
  • What is currently at risk?
  • Who lacks access?
  • What mechanism will your idea scale?
• Build a clear statement of practical impact:
  • Safe water, sanitation access, behavioural adoption, or ocean-related resilience outcomes.

2) Package your proposal for review

You should build a submission around evaluation language the judges already use:

• Replicability: Can your concept work in other locations with limited adaptation?
• Scalability and sustainability: Can this move beyond one pilot?
• Practical applicability: Is this implementable with plausible resources?
• Equity of access: Does the solution include populations that usually get left out?
• Stakeholder effects: What is the local impact and who benefits?
• Community engagement: Is there a stakeholder pathway and accountability mechanism?

Do not only describe the problem. Show your response path: baseline, implementation, evidence, and pathway to real-world use.

3) Submit on the official platform

The challenge instructions require submission via the RELX challenge application process; the official rules direct participants to the challenge site/application path. The specific portal may show intermittent technical status messages, so plan technical time and do not rely on an instant final confirmation signal.

4) After submission

• Confirm you submitted within the official window.
• Keep all entry records and correspondence.
• Be prepared to supply proof requested by RELX.

What judges are likely to reward

The most important lesson from the official scoring language is this: this is a competition about real-world usability and credible scale logic, not only theoretical quality.

Winning proposals tend to do five things better than average:

1. Start with real evidence of need They show where access currently fails and why current interventions are insufficient.

2. Avoid generic claims Broad ambition is not enough; the judges look for concrete pathways and measurable outcomes.

3. Design for adoption The solution should be understandable, deployable, and repeatable.

4. Demonstrate impact chain Problem → intervention → measurable improvement → community-level effect.

5. Show local relevance and ownership Community-level engagement is explicitly listed in judging language and is often under-scored by purely top-down submissions.

Common mistakes that weaken entries:

• Submitting a vague concept without proof of practical path.
• Ignoring the eligibility or age/authority requirements.
• Submitting multiple or duplicate entries across aliases.
• Missing practical implementation detail because the submission looks like a concept note instead of a prototype pathway.
• Skipping proof-of-authority for team or organisation submissions.

Risks, terms, and legal details to account for

Because this is a branded corporate challenge, participants should expect strong legal framing. The official rules include:

• Intellectual property handling and ownership obligations.
• Right-to-use terms (names and materials may be used by RELX in publicity).
• No purchase requirement.
• Eligibility verification and disqualification at RELX discretion.
• Governing law in England and Wales.

What this means in practical terms:

• Do not submit intellectual-property-infringing material.
• Confirm authorship and contributor rights before submission.
• Be comfortable with possible public acknowledgment if selected.
• Keep all declarations consistent with your submitted narrative.

The rules also state entries become property of sponsor upon submission and incomplete entries are disqualified. That is standard for this type of challenge but materially important.

Practical strategy for stronger submission quality

Use the challenge format, not a traditional grant template

A lot of applicants build an overlong academic paper. This format punishes that. Better approach:

• Lead with the urgent problem statement.
• Explain your unique intervention and who it serves.
• Show why your method is superior in practical impact.
• Include implementation assumptions and milestones.
• End with measurable outcomes.

Build a 1-page reviewer summary

Even when full platform fields are larger, create a one-page internal version before finalizing your entry:

• Category
• Target population and geography
• Innovation summary
• Distinctiveness
• Scaling plan
• Implementation timeline
• Expected social/environmental impact
• Resource needs (lightweight)

Judging is often influenced by clarity. This helps with coherence.

Emphasise locality and equity

Both the page and official criteria reward local context. Good submissions connect the technical idea to a specific community pathway:

• Who has the problem
• How the solution fits existing systems
• What local actors do
• How benefits are distributed fairly

Pre-empt disqualification triggers

Review your submission against the explicit disqualifier list:

• Incomplete fields
• Late submission
• Duplicate application patterns
• Missing eligibility facts
• Misaligned claims that conflict with rules or laws

FAQ

Is this only for NGOs and students?

No. The challenge is explicitly open to individuals and organisations, including not-for-profit and for-profit entities, plus educational institutions.

Does it require that teams be based in the UK?

No. RELX describes global participation, but applicants remain subject to applicable law in their own jurisdiction.

Is the prize total at least US$150,000?

Official rules list up to two prizes at US$75,000 each, total estimated value at least US$150,000.

Is the challenge only for fully developed products?

No. Early-stage projects are acceptable; judges are explicitly receptive to practical, early-stage concepts if they are implementation-ready and impact-oriented.

Can organisations apply?

Yes, including not-for-profit and for-profit organisations. If applying as an organization, ensure the submitter is authorised to represent the entity.

Is there a minimum age?

Yes, 21+.

Can I submit as part of a team and again individually?

You can only submit one entry as an individual or organisation. Multiple entries from one person or organisation can trigger disqualification.

If you are deciding whether to apply this month

Treat this as a short-cycle execution challenge rather than a long-cycle program. Most high-performing entries use simple language, tight implementation logic, and measurable outcomes. If you have a concrete concept with a known user pathway, this is one of the stronger global impact challenges for water and sanitation innovators because it pairs clear judging criteria with a defined two-prize structure and a fixed close date.

If your idea is still at concept stage, focus on one clear pain point, one community, and one implementation path. Build evidence incrementally, then submit before the July deadline window closes.
