Sonnenerde has been a pioneer in the European biochar market since 2012, converting organic waste into biochar – a material produced by heating organic residues in a low-oxygen environment. This process stores CO₂ in a stable carbon form and contributes to long-term carbon storage. Based in Riedlingsdorf, Austria, Sonnenerde uses screening residues from its own composting facility as feedstock.

Belgium’s agricultural sector is at a turning point, as conventional farming practices can degrade soil health and increase vulnerability to droughts and floods. Soil Capital addresses this by operating Europe’s first certified carbon payment programme, rewarding farmers for adopting practices that support climate mitigation.

Exomad Green operates a large-scale biochar carbon removal project, converting sustainably sourced forestry residues into biochar. Through pyrolysis – a high-temperature process in a low-oxygen environment – carbon is transformed into a stable form that can be stored over long periods.

The reforestation project in Colombia’s Vichada region covers around 76,000 hectares, including approximately 8,000 hectares designated for conservation. Previously unused savannah areas are being reforested with species such as teak, pine and eucalyptus, creating mixed forest landscapes and habitats for a wide range of plant and animal species.

Klim’s regenerative agriculture project supports soil restoration and climate protection in Germany. Working with more than 3,500 farmers across over 700,000 hectares, Klim promotes the transition to regenerative practices such as diverse crop rotations, reduced tillage, continuous soil cover and the use of organic fertilisers.

Mammoth is one of Climeworks’ largest direct air capture and storage facilities. Located in Hellisheiði, Iceland, it has been in operation since May 2024. The plant captures carbon dioxide (CO₂) directly from the air and stores it underground, where it is mineralised and permanently bound in rock.

This community-led project in rural India is one of the largest biochar initiatives globally. It converts biomass into biochar through high-temperature pyrolysis, enabling long-term carbon storage by transforming atmospheric CO₂ into a stable form.

Sistema.bio addresses challenges such as energy access, waste management and soil health by providing smallholder farmers with modular biodigesters. These systems convert animal manure into biogas for cooking and farm use, as well as nutrient-rich organic fertiliser.

Italian agriculture currently faces severe challenges from soil degradation and climate change. The project supports the adoption of thirteen evidence-based regenerative practices, from cover cropping and reduced tillage to compost, biochar use, and agroforestry. Farmers receive technical support and training to integrate these practices, which increase soil carbon sequestration while improving productivity and reducing chemical dependency.

In rural communities in the Siaya region of western Kenya, cooking has traditionally relied on open fires requiring large amounts of firewood. Through community savings and lending groups, households gain access to more efficient cookstoves. This reduces firewood consumption and helps decrease pressure on local forest resources, contributing to lower emissions.

MicroEnergy Credits supports improved air quality and reduced emissions in Mongolia by facilitating access to efficient heating technologies for low-income households. In partnership with XacBank, the programme provides financing for efficient furnaces and home insulation, helping to reduce fuel consumption. Since 2009, the project has reached more than 160,000 households.

Recoal develops solutions for managing biomass residues that would otherwise release CO₂ and methane during decomposition. Its approach is based on Biomass Carbon Removal and Storage (BiCRS) using Hydrothermal Carbonisation (HTC), which converts biomass into stable carbon materials for long-term storage.

This project promotes the use of energy-efficient and durable cookstoves in Ugandan households. Compared to traditional cooking methods, these stoves can significantly reduce fuel consumption. The initiative supports both distribution and awareness, and has reached over 6 million people to date.

The STRATOS facility by 1PointFive, located in the southern United States, captures carbon dioxide directly from the atmosphere and stores it securely underground. As a large-scale direct air capture project, it contributes to the development of scalable carbon removal technologies.
