• Through the partnership, Key Carbon has the right to invest over €100 million into InSoil’s zero-interest Green Loans. This provides vital financing to small and medium-sized farms transitioning to regenerative agricultural practices over the next several years.
  • In a royalty agreement, InSoil has received a €3.7 million investment from Key Carbon. This is to scale its operations across one million hectares of European farmland by 2026. This will enable the sequestration of over 35 million tonnes of atmospheric carbon dioxide (CO2) emissions.
  • This milestone marks InSoil’s (formerly HeavyFinance) largest funding to date. Additionally, it is one of Europe’s largest financial commitments to climate-resilient farming practices.

Vilnius, Lithuania, & Vancouver, British Columbia,  June 10th, 2025 – InSoil, a climate finance company, and Key Carbon, a leading financier within the voluntary carbon market, have entered into a €100 million agreement. This will enable climate-critical transitions to regenerative agriculture across one million hectares of European farmland. 

The multi-year partnership is InSoil’s largest raise to date. It is also one of Europe’s largest financial commitments to climate-resilient farming. The deal grants Key Carbon royalty rights to InSoil’s Green Loans financing model, offering zero-interest loans to farmers adopting regenerative practices. In return, they receive a fixed share of carbon credits. In addition, Key Carbon’s subsidiary, EU Soil Carbon Corp, will fund the expansion of InSoil’s carbon farming business. It provides farmers with further technical and financial support in implementing regenerative practices.

“As farmers across Europe face headwinds from climate change and global regulatory dynamics, financial and agronomic support from projects like these is critical. It helps achieve the systemic shifts that lead to real impact in carbon sequestration. Furthermore, it builds a more resilient food system that doesn’t leave the stewards of our lands in the dust,” said Laimonas Noreika, CEO of InSoil. “Through this agreement with Key Carbon, we will reach more farmers, accelerate climate-positive outcomes, and deliver the high-integrity credits the carbon market increasingly demands. As institutional interest in nature-based solutions continues to grow, our work with Key Carbon will represent a model. It blends sustainable finance with climate impact, and turns soil into both a climate solution and a revenue stream for European farmers.”

Luke Leslie, CEO of Key Carbon, said: “Corporate appetite for carbon credits is increasingly shifting towards high-integrity, removal-based and localised solutions. This helps meet evolving compliance standards. Our partnership with InSoil will provide increased access to funding for farmers, enabling the transition to regenerative agriculture. In addition, it will grow Key Carbon’s supply of high-quality carbon credits. With its deep agronomic expertise and strong local networks, InSoil is uniquely positioned to deliver meaningful environmental outcomes. It will ensure the integrity of carbon credit generation. The partnership will also provide Key Carbon with access to millions of hectares of European farmland. There is potential to deliver additional biodiversity monitoring.” 

Conventional agriculture accounts for more than 20% of global emissions. Meanwhile, soil is seen as a critical carbon sink. Therefore, this collaboration aims to unlock funds that help farmers generate high-quality, nature-based carbon credits. These are scientifically validated and third-party verified in alignment with the EU Carbon Removals Certification Framework (CRCF). As farmers transition to practices that align with regenerative agriculture principles, they increase biodiversity, build soil health, and improve water cycles. These practices result in more carbon drawdown and greater resilience to extreme weather events. InSoil’s Measurement, Reporting, and Verification (MRV) framework ensures accurate, transparent, and high-integrity carbon credit generation. These approaches include laboratory-grade soil sampling, advanced remote sensing technologies, expert agronomic assessments, and additional data-driven methodologies. 

InSoil’s private debt arm has already deployed over €80 million in financing to over 3,000 farmers. This funding from Key Carbon will enable European farmers to regenerate their lands. They will benefit from diversified revenue opportunities through carbon credit generation. Additionally, they will establish productive and profitable agricultural operations into the future.
