What is Weave?
Weave is a European cross-border initiative developed by European research funders with the aim of supporting high-quality international research collaborations. It is supported by Science Europe External link., a European association of research funders. The aim is to simplify the application and review processes for research applications. Research projects can collaborate with participants from two to three European countries. This is achieved by subjecting applications to a single review process.Weave includes calls for researcher-initiated research, known as open calls, and there are no major restrictions on the thematic focus or subject matter covered in the application, beyond what is stipulated in the respective areas of responsibility of the participating research funding bodies and the respective call.
Within Weave, researchers from two or three European countries can submit applications for research collaborations to any of the participating research funding bodies. Each participating researcher must be eligible for funding from their research funding body within Weave.
Which countries are included in Weave?
Weave comprises twelve national research funding bodies from eleven European countries. Together, they are committed to strengthening international research collaboration and contributing to the realisation of the European Research Area.
Researching funders in Weave:
- Belgium: Research Foundation Flanders FWO External link.
- Belgium: Fund for Scientific Research FNRS External link.
- Croatia: Croatian Science Fundation HRZZ External link.
- Luxembourg: Luxembourg National Research Fund FNR External link.
- Norway: Research Council of Norway RCN External link.
- Poland: National Science Centre NCN External link.
- Switzerland: Swiss National Science Foundation SNSF External link.
- Slovenia: Slovenian Research Agency ARRS External link.
- Sweden: Swedish Research Council for sustainable development, Formas
- Czech Republic: Czech Science Foundation GACR External link.
- Germany: German Research Foundation DFG External link.
- Austria: Austrian Science Fund FWF External link.
Weave will be rolled out gradually over the coming years. Initially, participating research funding bodies will only accept applications from research funding bodies with which they have standing agreements, but this will be expanded gradually.
Which research funding bodies is Formas currently collaborating with?
Within Weave, Formas currently collaborates directly with three research funding bodies:
Norway new partner in 2026
The Research Council of Norway is now opening up for Weave collaboration with Formas. Through a pilot project in 2026, Swedish researchers will be able to apply jointly with Norwegian colleagues via Explore. It is also possible to apply trilaterally – see more under the section "Trilateral application" below.
How does Weave work?
Weave was developed by European research funders to support high-quality research projects. It makes it easier to submit joint applications by having the assessment carried out by a single research funder. In Weave, researchers from two to three European countries submit a joint proposal to one of the research funders involved. Each applicant must then meet the participation requirements and eligibility criteria specified by the respective funding body. The lead applicant must meet the requirements and eligibility criteria of their national funding body, the Lead Agency, and each co-applicant must meet the requirements and eligibility criteria of their own national funding body, the Partner Agency.
Formas participates in Weave through Explore – Formas’ open call for research projects.
How to apply within Weave
- The researchers appoint a lead applicant who submits the joint application to their country's research funding body (Lead Agency).
- For administrative reasons, co-applicants must also submit parallel applications to their respective countries' national funding bodies (Partner Agencies).
- The Partner Agency performs eligibility checks in accordance with national processes. The Lead Agency is then notified if the application meets the basic requirements and can proceed to further review by the Lead Agency.
- The application is then reviewed by the Lead Agency in accordance with its call process.
- The application is then approved/rejected in its entirety and the decision is communicated to the main applicant at the Lead Agency, while the Partner Agency is also informed.
- If approved, Formas is responsible for the budget for the Swedish part of the project, while the respective partner country's finances the other parts of the project.
The difference between bilateral and trilateral applications
Bilateral application
It is possible to submit a bilateral application, i.e. apply with another country, if this is done together with one of the countries with which Formas has an agreement (see the section above entitled “Which research funding bodies is Formas currently collaborating with?”).
Trilateral application
It is possible to submit a trilateral application, i.e. apply with two additional countries within the collaboration, under the following conditions:
- If it is done with Formas as the Lead agency and together with two additional countries with which Formas has a collaboration agreement (see the section above entitled “Which research funding bodies is Formas currently collaborating with?”)
- If it is done with Formas as the partner agency and with one of the countries with which Formas has an agreement (see the section above entitled “Which research funding bodies is Formas currently collaborating with?”) as the lead agency. The country acting as the lead agency then determines which additional country can be the third country, i.e. one of the countries with which the lead agency country in turn has an agreement.
If Formas is the main research funder, Lead Agency
Submitted Weave applications participate on an equal footing with the other applications submitted to Utforska. Weave applications submitted to Utforska with Formas as Lead Agency must follow the guidelines in Utforska.
- The project description must cover the entire bilateral or trilateral research project.
- The division of labour between the parties must be clearly described.
- In the application, applicants based abroad must be listed as participating researchers, co-applicants, in Prisma. Follow Utforska's guidelines for participating researchers.
- The budget must be justified and include information about both the Swedish and other international parts of the project.
- You can only be the principal applicant in one application submitted to the Explore call, including Weave applications.
If Formas is a participating research funder, Partner Agency
When another country and funder within Weave acts as Lead Agency, the application must be prepared in accordance with this research funder’s call guidelines, which may entail requirements for a shorter project duration than Utforska’s requirements. Read the information and follow the guidelines on the organisation’s website, and contact them if you have any questions about the call and the procedure.
As a co-applicant, you must email the following documents to the Partner Agency within seven (7) days of the application deadline:
- An exact copy of the application submitted to the Lead Agency to Formas' contact persons for Weave – see below. The Swedish part of the budget must be clearly distinguishable and include information about both the Lead Agency's and the partner agencies' parts of the project.
- A letter of intent (LoI) from your Swedish administrating organisation. This should include a statement that the applicant and the project will be approved by the funding administrator.
More about the application procedure when Formas is the Partner Agency
- If the application complies with the rules of the call, the Lead Agency forwards the decision to Formas (as Partner Agency) for a formal check and budget assessment.
- If the main applicant is not eligible or if the application does not comply with the rules of the call, the Lead Agency will reject the application and Formas will be informed.
- The Swedish partner's part of the application undergoes a formal check in accordance with Formas' guidelines for the Explore call.
- If Formas or another Partner Agency discovers that the applicant or the applicant's project part does not meet the requirements for their respective call, the entire application is rejected.
- The administrating organisation will need to sign and approve the application in Prisma once it has been registered there (done by Formas).
- If the project receives funding from the Lead Agency, the Swedish part will receive funding from Formas (as Partner Agency).
Project duration
The maximum project period for which an application can be submitted depends on which research funding bodies are involved. If the joint proposal is submitted to Formas within the framework of the Explore call, the guidelines for that call apply. If the application is sent to a funding body abroad, the maximum project period depends on the respective Lead Agency. It is determined either by the rules for the call to which the project is submitted, or by the research funding organisation that allows the shortest project period. If necessary, check with the Lead Agency or your own funding organisation before submitting a proposal.
Budget and costs
There must be a clear budget and budget justification for the Swedish part of the project as well as for the other applicants' budgets in the application. The parts of the project are funded separately by the respective national/regional funding bodies in accordance with their standard rules. Applicants are advised to check with their respective funding bodies. Swedish project parts follow the budget rules in the Explore call. This applies regardless of whether Formas is the Lead Agency or Partner Agency.
To calculate costs, the guidelines from each national funder apply. The separate project budgets from the different national research funders are then combined to make up the total budget.
Language
The application should be written in English. The review panel consists mainly of international reviewers and partners, and the project’s Partner Agency or Lead Agency is located in a country other than Sweden.
Submission deadlines
The deadline for submitting applications varies depending on the Lead Agency, so please check the information pages for each country. If Formas is the Lead Agency, the same deadline applies as for the Explore call.
Approval rates
The approval rate varies for each Lead Agency, as it varies between different calls within Weave. If Formas is the Lead Agency, the application is in competition with all other applications in the Explore call for that year (in 2024, the approval rate was 7 per cent).
Principle of public access
Applications submitted within the framework of the Weave collaboration are handled according to a special procedure. This is to comply with jointly agreed practices between the international funding bodies.
Q&A about Weave
How does Weave work?
Researchers from two or three countries submit a joint application to a Lead Agency. Each researcher must simultaneously meet the requirements of their own Partner Agency.
What is a Lead Agency?
It is the research funding agency that receives and evaluates the entire joint application.
What is a Partner Agency?
The participating researchers' respective national funders perform formal eligibility checks and finance their respective parts of the entire project.
How do you apply within Weave?
1. The main applicant submits the application to the Lead Agency.
2. Co-applicants submit in parallel to their Partner Agencies (to Formas for Swedish applicants)
3. The Lead Agency makes the assessment.
4. The decision applies to the entire project.
5. Each country funds its part of the entire project.
Difference between bilateral and trilateral applications?
Bilateral: two countries.
Trilateral: three countries.
Which countries can participate depends on agreements between the funders. For Formas, see "Which research funders does Formas currently cooperate with?"
If Formas is the Lead Agency?
The application is assessed within the Explore call and must cover the entire project, and include the international budget.
If Formas is a Partner Agency?
The application follows and is assessed according to the Lead Agency's rules. Formas carries out an eligibility check according to Explore's guidelines for each Swedish project part.
Project period?
When Formas is the Lead Agency, the entire project follows Explore's project period of four years (48 months). When Formas is a Partner Agency, Formas follows the Lead Agency's project period. Keep in mind that the budget for the Swedish part must be reduced in proportion to the project period. For example, for a 3-year project, one can apply for a minimum of 3.75 million kronor and a maximum of 4.5 million kronor.
Budget?
Formas funds the Swedish part of the budget. The Swedish project part must follow the Explore rules regarding the budget. The budget can be lower but only if the project duration in the call from the Lead agency is shorter than Explore's project duration. In that case, the grant amount is simultaneously reduced proportionally: for example, for a 3-year project, you can apply to Formas for at least 3.75 million SEK and at most 4.5 million SEK (equivalent to 5 – 6 million SEK for 4 years).
To calculate costs, the guidelines from each national funder apply. The separate project budgets from the different national research funders are then combined to make up the total budget.
Difference between bilateral and trilateral applications?
Bilateral: two countries.
Trilateral: three countries.
Which countries can be included depends on agreements between the funders. See more under "Which research funders do Formas currently cooperate with?".
Can you apply trilaterally when Formas is the Lead Agency?
It is possible if Formas has bilateral agreements with both the other countries.
It is not possible to include a third country with which Formas does not have a bilateral agreement within Weave. See more under "Which research funders do Formas currently cooperate with?".
Can you apply trilaterally when Formas is a Partner Agency?
This can be done with Formas as a Partner agency and with one of the countries that Formas has a bilateral agreement with as the Lead agency. The country acting as Lead agency then determines the limitation for which additional country can constitute the third country, i.e., one of the countries with which the Lead agency-country itself has an agreement.
Language?
The application should be written in English.
Deadlines?
Varies depending on Lead Agency. If Formas is the Lead Agency, the Explore deadline applies.
I want to apply with Formas as a partner agency; which year's Explore call applies?
When you apply with Formas as partner agency in Explore, the main rule is:
you follow the year of the Explore call that is published on the Formas website when the partner agency call closes.
How to determine which year applies:
1. Go to the current partner agency call.
2. Check the application deadline for the partner agency part.
3. See which Explore call is published on the Formas website at that date.
4. That version's guidelines apply (budget rules, eligibility, project duration, etc.).
Example
• If the partner agency closes before Explore 2026 is published → then Explore 2025 applies.
• If the partner agency closes in October 2026 and Explore 2026 is already published → then Explore 2026 applies.
