All EU funding programmes for the environment

In addition to Interreg, the EU offers many other ways to support projects for the environment. To help navigate this, the European Commission has created a vademecum. This is an online guide about the programs and the most important conditions. The guide is available in English and Dutch.

Interreg-program's

You can read more about the Interreg North-West Europe (NWE), North Sea and Europe 2021-2027 programmes below.

North-West Europe (NWE)

Interreg North-West Europe (NWE) is a transnational programme. It focuses on the participation of parties from 6 countries in Northwest Europe. Parties from Switzerland can also participate.

The goal is green, smart and fair improvement for all NWE areas. In addition, with NWE, the EU wants to develop every country equally and make all regions more resilient.

See more information on the Interreg North-West Europe page

North Sea

Interreg North Sea is a transnational programme. It focuses on cooperation between parties from 7 countries around the North Sea. The aim of Interreg North Sea is to encourage innovation and more sustainable economic growth in the North Sea region.

More information can be found on the Interreg North Sea page

Europe

Interreg Europe supports interregional cooperation throughout Europe. It concerns all 27 countries of the European Union, the European Union (EU) or Albania, Bosnia and Herzegovina, Moldova, Montenegro, North Macedonia, Norway, Serbia, Ukraine and Switzerland. Interreg Europe focuses on improving tools for laws and regulations for development in the region.

The programme co-finances projects and networks for governments in the region or locally and other partners. On this platform, they exchange practical examples and ideas to improve their tools for policy.

More information can be found on the Interreg Europe page

Changes in new period

Are you familiar with previous Interreg programming periods? One of the changes in the period 2021-2027 is that NWE and North Sea apply to the whole of the Netherlands. The programme area is also changing in other countries. The United Kingdom no longer participates in this period.

In terms of content, the programmes are mainly in line with the European Green Deal. Important themes are:

  • climate adaptation
  • water management
  • renewable energy
  • circular economy

In addition, innovation is a pillar within every program. Green and Smart, in other words. At North Sea, (maritime) governance is also an important theme.

Information and inspiration on EU websites

There are also specialised websites of the I[nterreg programmes.

  • On the Interreg website you can read about how Interreg fits into the general cohesion policy, about the different programmes and which programmes have a call for projects.
  • On the keep.eu website you will find almost all Interreg projects that have been implemented since 2000. You can select by program, theme, subject, country and make combinations with them. This will show you the topics of previous Interreg projects, and their results.

Tips for the 2021-2027 kick-off

On 16 September 2020, we organised a kick-off for the programmes in 2021-2027. 

Tips from the kick-off:

  • Start a project from a need. This can be the policy of your organization, or a need from the network in which you have a role;
  • Prior to an Interreg project, think about co-financing and follow-up financing;
  • Put people at the heart of the project approach. Think of the right profile in the right place in your organization, but especially of a common goal and division of ownership;
  • Ensure political support. An 'ambassador' can help make the project a success;
  • As a 'lead partner' of a project, you have the greatest control over both the project progress and the content and 'impact'. Of course, it requires a lot of attention and problem-solving skills. Regional organisations can of course also choose to participate as a 'regular' project partner in the transnational consortium.

Financial questions

We have an expertise centre for financial questions about Interreg. This centre also approves the financial controllers who appoint projects according to EU regulations. The rules for an inspection in the Interreg period 2021-2027 are different than in 2014-2020. See Interreg financial control 2021 - 2027 for more information.

You can contact us for the Interreg programmes North-West EuropeNorth Sea and Europe. Even if you would like to have a First Level Controller approved for the Two Seas or URBACT programmes.

Would you like to change something in a previous 'FLC approval' (both for the above-mentioned programmes and for Twee Zeeën and URBACT)? See Interreg 2014-2020 for more information.

You can reach the expertise centre for financial questions via interreg@rvo.nl.

Background

Interreg was founded in 1990 to improve cooperation between regions within Europe. It is one of the oldest and largest grant funds that finances cooperation in projects between national, regional and local parties from different Member States. The basis of Interreg is cooperation, just like the basis of Europe.

For the period 2021-2027, Interreg consists of 71 programmes in which there is cooperation in different ways. A four-tier division includes several cooperation programmes that are classified on the basis of geographical location, common challenges and goals: Interreg A, Interreg B, Interreg C and Interreg D.

In addition, there are 24 programmes aimed at cooperation with countries that may still join the EU and countries on the EU's eastern and southern external borders. The Netherlands does not participate in this.

Interreg A

These programs are located along the borders of countries. We therefore call them 'cross-border' programmes. There are 49 cooperation programmes within Interreg A. Together, these cover the 27 countries of Europe - with a number of countries outside the EU with which we cooperate. €6.5 billion is available for projects. The programmes for the EU's external borders are also part of this. Dutch parties can participate in the following Interreg A programmes:

More information about Interreg A can be found on Rijksoverheid.nl.

Interreg B

Interreg B programmes are transnational. Several countries are working together on this. These areas are larger than in the A programmes. There are 14 cooperation programmes within Interreg B. They have a total budget of €1.5 billion. These programmes focus on various topics such as (social) innovation, sustainability, urban-rural development, transport and an inclusive society. The following Interreg B programmes are available for Dutch parties:

It is possible to participate in one of the other B programs, but there are conditions attached to this. Both on the program side and from the Dutch government. If you are planning to participate in one of the other program areas, please always contact us via interreg@rvo.nl to discuss the possibilities.

Interreg C

Interreg C is an interregional Europe-wide programme. There are 3 cooperation programmes that target all 27 Member States of Europe and a number of partner countries outside the EU, such as Norway, Iceland and Switzerland. You can apply for a subsidy from these programmes.

  • Interreg Europe has a budget of around €379 million. It focuses on improving the implementation of regional policy. This policy has been developed, for example, in the national programmes, the ESF or other Interreg programmes.
  • URBACT focuses specifically on urban problems and is coordinated in the Netherlands by the Ministry of the Interior and Kingdom Relations.
  • ESPON is a research programme on issues of spatial planning and territorial cohesion and is coordinated by the Ministry of the Interior.

In addition to these 3 project programmes, there is the Interact programme. This focuses on knowledge exchange between and about Interreg programmes. You cannot submit projects for this. The total budget for these 4 programmes is €550 million.

Interreg D

There are 4 programmes that focus on European territories that do not belong to the European continent. One of them focuses mainly on the Spanish and Portuguese islands in the Atlantic Ocean. The others focus mainly on the French overseas territories. The programmes are also open to other countries in those regions. A total of €280 million is available.
