The goal of the Carbon Action platform is systemic change towards regenerative agriculture. Regenerative agriculture enhances soil health as it restores the carbon content, which, in turn, improves productivity. It also increases biodiversity and ecosystem resilience and provides many other benefits like water infiltration and nutrient retention.

On the Carbon Action platform farmers, advisors, scientists, companies, and decision-makers work together. The platform contains several funders and projects. Carbon Action enables concrete co-operation and co-development between the different actors and projects. The holistic approach has evoked international interest.

Towards regenerative agriculture – where are we now?

Farmers and advisors: Carbon Action is farmer-based and constantly taking shape in interaction with the farmers. 100 Carbon Action Farms test practices, accumulate experiences, and provide data for research. Farmers benefit directly from peer learning (1, 2, 3). For Carbon Action farmers, collaboration with researchers has been valuable, and correspondingly, researchers have received practical insights from farmers.

New carbon farmers have been reached through business cooperation (see below) and through the Carbon Action Club (link in Finnish) – which is open for all farmers – and by expanding towards the Swedish-speaking farmers in Finland. The Carbon Action Club has now about 1 000 members. Carbon Action platform also trains 30 agricultural advisors to become top experts in soil health and carbon farming. In addition, a free e-college for regenerative farming has been launched in 2021. The course combines improving the productivity of farming with hands-on environmental work. The e-college is suitable for all kind of farms and circumstances, and it is provided in Finnish and Swedish. The college has now about 1 600 registered participants.

Based on the scientific work, Carbon Action platform also produces practical papers for farmers, as an example a publication on catch and cover crops (short version also in English) and paludiculture (in Finnish here).

Scientists: The Carbon Action platform brings together and conducts scientific research to e.g., enhance soil carbon sequestration. The platform contains multiple research projects and a multi-disciplinary network of researchers. Research is conducted and utilized at several levels from soil processes (4, 5) to climate and agricultural policies (6). Soil and microbial analyses, plant diversity measurements (7), atmospheric measurements, and modelling (8, 9) are used to study fluxes and sequestration of carbon at study sites. Nutrient retention and nutritional quality of the agricultural products are also studied. Economical and policy analyses are carried out to develop feasible, effective, and practical solutions of carbon farming.

The hundred Carbon Action Farms test carbon farming and provide research material. The first samples from the Carbon Action farms test and control plots have been analyzed and subsequent samples will be taken after five years to measure changes. Also, soil samples have been taken from 30 farms to a depth of one meter and the analysis of the samples is ongoing.

More detailed field experiments studying the impacts on carbon fluxes and sequestration have been established on 20 of these Carbon Action Farms. Farmers on these farms can monitor the effectiveness of carbon farming measures at the field level, and the results are published annually on a Zenodo server (keyword ‘Carbon Action’). The results show how different plots react to droughts and heavy rains and how plants grow in different plots. The results also help farmers find ways to develop plant and soil resilience in a changing climate.

At long-term study sites, both changes in soil storage and nutrient emissions are studied. The work has started in summer 2020.

At the intensive study sites, soil analysis, microbiological analysis, atmospheric measurements, and modelling are used to study the fluxes and sequestration of carbon (10). Through the Carbon Action co-operation, existing study sites have been further developed (Qvidja, Viikki, Kilpiä, and Ruukki), and new ones have being established together with the University of Helsinki (Haltiala). In addition, long-term field experiment has been established in Viikki to study how biodiversity impacts the ability of fields to store carbon (11).

Carbon Action is developing a scientifically ambitious measurement and verification system (12). The verification system uses extensively collected data and can model and predict carbon sequestration even in areas where measurement data are scarce. The observations and findings from our research results are disseminated on a free-access online dashboard called Field Observatory. This website serves as a tool to monitor the impacts of carbon farming practices from our three intensive study sites and 20 Carbon Action farms. Data from field sensors, remote sensing and field survey is integrated on this dashboard (13). The observatory also shows the world’s first carbon sequestration forecasts on grasslands. To serve the research and other interested communities, the data in Field Observatory is publicly available and downloadable from the website. On a societal level, scientific verification provides a basis for agricultural and climate policy instruments and a possible carbon credit market.

Carbon Action science webinar on ‘’soil, carbon sequestration and water protection’’ on 9th of March 2021, brought out novel research results on managing soils for both increased carbon sequestration and reduced phosphorus losses. The recording and summary can be found here.

Companies: Businesses have great potential in driving the adoption of regenerative farming. There are currently 13 companies in the Carbon Action company platform and new ones are coming aboard.

To make carbon sequestration mainstream, businesses are needed to bring about substantial changes and embed them permanently in the food supply chain. Businesses also communicate the message to consumers. Cooperation between the scientific community and companies is important so that science can produce solutions that are necessary and can be implemented in practice. The results of the scientific community are of interest to participating companies, as companies need to be able to base their sustainability work on researched knowledge. In the project, the companies also learn about the farmers’ needs and farmers learn about the expectations of the companies.

On the business platform, the focus is on concrete changes in the way companies operate. For example, ValioAtria, Anora, DAVA Foods and Nestlé Finland are organizing carbon farming training for their farmers. The sourcing of raw materials will change extensively as companies bring the principles of carbon farming into their sourcing criteria – as Anora, Apetit, and Fazer have committed to do. Nestlé Finland spreads information from the Carbon Action platform within the Nestlé Group. Leijona Catering increases the share of regeneratively farmed food, develops understanding and shares information on regenerative farming.

The first carbon farmed product has been launched by Anora, and Sinebrychoff’s Christmas beer 2021 came from a Carbon Action farm. Gofore aims to support Carbon Action by harnessing digitalization for regenerative agriculture. Berner develops its product portfolio so that it supports farming methods that promote soil health and carbon sequestration. The S-group supported Carbon Action research, as scientific verification of soil carbon storage is one of the missing steps in advancing carbon offsets.

The investments of the companies of the global food-chain into regenerative farming are increasing, and the work of Carbon Action attracts interest. We discuss cooperation with international companies and share our expertise collected through Carbon Action work when invited to events and working groups organized by companies. Examples of this are: working as the facilitator at the UN Food Systems Summit Dialogue by Nestlé and advising Arla in a working group.

Decision-makers: The work of Carbon Action has influenced national decision-making on many levels. For example, the Finnish government program and its implementation emphasizes soil carbon sequestration. CAP recommendations have been delivered through policy brief publications (1), official statements, and parliamentary committee hearings. Carbon farming was also well on the agenda during Finland’s EU presidency in 2019 – both at various events and at the EU agriculture ministers‘ meeting. In the climate roadmap of agricultural interest groups (MTK and SLC), the focus is on the soil.

At the EU level, Carbon Action has had an impact on the EU’s Carbon Farming Roundtable, which is a part of EU Commission’s carbon farming incentives and carbon market work. Carbon Action has been visible both as an example and to influence the debate. We have also organized discussions together with MEP’s, topics include CAP (see more: webinar with MEPs 29.10.2020).

In addition, voluntary carbon farming markets are piloted in collaboration with the Carbon Action platform (14). The pilot was conducted during 2021, and the results are used to develop guidelines for a future EU carbon market system.

International networks: Systemic change in the field of agriculture is in progress globally (read more on this blog). Cooperation and co-development with international regenerative agriculture networks is important for Carbon Action.

Carbon Action has been well noticed as part of the forerunner networks. For example, Carbon Action has been invited to speak at the Madrid (COP25) and Glasgow (COP26) Climate Conferences (4 per 1000 initiative event). In 2023, Carbon Action will organize a 4 per 1000 Northern Europe event in Finland: More carbon in the soil for multiple benefits.

In addition, co-operation among countries with similar growing conditions is important, and we have strong co-creation with Swedish ‘Svensk kolinlagring’. Carbon Action also won a Diploma of Recognition at Land and Soil Management Award competition in 2021, the Diploma was given during the Forum of the Future of Agriculture (FFA2021). Moreover, in 2021 Carbon Action was nominated for the Nordic Environmental prize.

Carbon Action also promotes soil to a wide audience – and brings it to all senses to turn knowledge into action. For example, in different events, in addition to high-quality science, food from the Carbon Action farms has been served, science-based soil art presented, pop down dinner organized underground (combining art, science, and carbon-farmed gourmet), and trips organized to the intensive study site in Qvidja – in order to dig the hands in the soil on the field. We also organize regular successful ’Save Our Soil’ SOS courses for various stakeholders (for example decision-makers such as key ministers): during spring an SOS breakfast with new research and practical knowledge fresh from the fields and in autumn a visit to the Intensive study site at Qvidja. This kind of concept has provoked a lot of interest and we have been able to also entice very busy people from high-level and media.

Soil is also promoted through social media campaigns (read more about the #SoilSelfie campaign) and at the international Soil at Risk -symposium in 2021. The symposium had about 300 participants, and reached almost million through social media. A lot of different blogs and video material with different stakeholders were produced for the symposium – discussing the importance of soil with farmers, artists, decision-makers, a top chef, and company representatives.

The success of the Carbon Action work has proved to us that as we work together and learn from each other, we have hope, and the change is possible, though not at all easy. We need farmers, science, politics, NGOs, business, and citizens all aboard. By now we know that the transformation of the food system can be done – in fact, it is already ongoing. What we need is to join efforts and accelerate the work.
