More. Our mission: spark conversations, unlock markets, inspire innovation, and drive change where biochar can make a real difference. Each profile reveals how a nation can transform its environmental, social, and economic landscape through biochar, proving its vital role in a sustainable future.

Latvia, a Baltic gem draped in forests covering over half its land (indicated in green on the map below), faces a silent environmental crisis. Despite its green reputation, Latvia’s land use, land-use change, and forestry (LULUCF) sector—driven by its robust timber industry—is now a net carbon source, not a sink. This shift from carbon asset to carbon liability is an obstacle to Latvia’s ambitious climate goals.

In this article, I explore the ways that biochar could offer a solution to Latvia’s issue that would result in socio-economic benefit also. Applied to land, it locks away carbon for centuries while dramatically boosting soil health and productivity. For Latvia, overflowing with forest and agricultural residues, biochar isn’t just a soil amendmentA soil amendment is any material added to the soil to enhance its physical or chemical properties, improving its suitability for plant growth. Biochar is considered a soil amendment as it can improve soil structure, water retention, nutrient availability, and microbial activity.   More. It’s a strategic weapon to turn its biggest environmental challenge into a cutting-edge solution for climate resilience and a thriving circular bioeconomy.

Latvia’s Environmental Crossroads: From Carbon Sink to Source

Latvia is racing towards climate neutrality by 2050, targeting a 65% cut in greenhouse gas (GHG) emissions by 2030. While progress shines in many sectors, the LULUCF sector stands out as a critical failure. Despite better data in 2023, Latvia’s net emissions were still 1.5 times above 2005 levels—primarily because its LULUCF sector flipped from a carbon sink to a source. This is a red-alert issue for Latvia’s climate commitments.

The culprit? The intensive use of Latvia’s forests and farmlands, economic pillars of the nation. The booming timber and agriculture industries churn out massive volumes of waste: brash, sawdust, wood chips, and agricultural by-products. Too often, these residues are left to rot, dumped in landfills, or burned, spewing CO2 and other GHGs back into the atmosphere and sabotaging Latvia’s climate efforts.

Biochar: A Strategic Solution for Latvia’s Key Sectors

Biochar offers a powerful, multi-faceted solution that directly addresses Latvia’s core environmental challenges. Now let me dive into some numbers to try and bring the opportunity to life…

The single most impactful use of biochar in Latvia would be to use forestry and agricultural waste as feedstockFeedstock refers to the raw organic material used to produce biochar. This can include a wide range of materials, such as wood chips, agricultural residues, and animal manure. More. To understand the scale of this opportunity, consider that Latvia harvests an average of 11 million cubic meters of timber annually. A common approximation for forestry waste (including logging residues and processing by-products like sawdust) is that it constitutes up to 55% of the processed wood. This means that Latvia could be generating upwards of 6 million cubic meters of forestry waste per year. Instead of letting this substantial volume of biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More decompose and release CO2, it can be pyrolyzed to create biochar. 

Modelling for Weight and Climate Impact

Whilst understanding volume can be useful for logistics, we often need to convert our measurements into weight data for insights into biochar quantity and, in turn, carbon sequestration potential. 

Of course to model this, we need some assumptions. To understand how Latvian timber is weighted, we need to know what varieties make up the industry. Largely dominated by deciduous tree species, Latvia’s timber sourcing demographic is thought to be as follows (using 11 million m³, as a total reference point):

• Pine (34.3%): 3,773,000 m³
• Birch (30.8%): 3,388,000 m³
• Spruce (18.0%): 1,980,000 m³
• Grey Alder (7.4%): 814,000 m³
• Aspen (5.4%): 594,000 m³
• Black Alder (3.0%): 330,000 m³
• Miscellaneous (1.1%): 121,000 m³

Then we need to consider each tree’s timber density, assumed to be:

• Pine: 425 kg/m³
• Birch: 660 kg/m³
• Spruce: 450 kg/m³
• Grey Alder: 400 kg/m³
• Aspen: 420 kg/m³
• Black Alder: 530 kg/m³

The remaining 1.1% of miscellaneous timber produced will be assumed to weigh 500 kg/m³. Meaning this would be the approximate total timber weight by tree variety:

• Pine: 1,603,525,000 kg
• Birch: 2,236,080,000 kg
• Spruce: 891,000,000 kg
• Grey Alder: 325,600,000 kg
• Aspen: 249,480,000 kg
• Black Alder: 174,900,000 kg
• Miscellaneous: 60,500,000 kg

The sum of these weights is 5,541,085,000 kg, which converts to 5,541,085 tonnes.

So if we use the same assumption of 55% of the total timber amount is waste… 

Latvia’s timber industry produces approximately 3 million tonnes of biomass waste. If all of this were to be converted into biochar through pyrolysisPyrolysis is a thermochemical process that converts waste biomass into bio-char, bio-oil, and pyro-gas. It offers significant advantages in waste valorization, turning low-value materials into economically valuable resources. Its versatility allows for tailored products based on operational conditions, presenting itself as a cost-effective and efficient More, Latvia could generate around 0.75 million tonnes of biochar per year (assuming a weight conversion of ‘-75%’, biomass to biochar). 

Such an endeavour would revolutionise forestry in the region, making sites more manageable, whilst producing a material that can enhance soil, improve water quality and sequester carbon. And this sequestration would be substantial. If we take our biochar potential projection figure of 0.75 million tonnes, we can estimate a potential carbon removal equivalent of 1.875 million CO2e (with 1 tonne of biochar = 2.5 tonnes of CO2e).

Latvia’s total annual emissions are around 6.51 million tonnes, meaning biochar could represent a removal of 28.8% of total emissions in the nation. 

From Research to Reality: Latvia’s Existing Biocarbon Ecosystem

While biochar may be an “undeveloped” field in Latvia on a national scale, the country is far from a blank slate. There is a nascent but significant ecosystem of research and industry that can serve as a powerful foundation for future growth.

The Latvian State Institute of Wood Chemistry (LSIWC) is a key player, conducting research on pyrolysis and biomass conversion. The Institute’s work is already being integrated into industrial processes, demonstrating a direct link between scientific innovation and practical application. For example, a charcoalCharcoal is a black, brittle, and porous material produced by heating wood or other organic substances in a low-oxygen environment. It is primarily used as a fuel source for cooking and heating.   More producer in Latvia, SIA “KRK Vidzeme,” is directly applying research from the LSIWC to produce high-quality charcoal (a form of biochar). This relationship highlights the strong potential for collaboration between academia and industry.

Furthermore, Latvia is actively involved in broader European bioeconomy initiatives. A Latvian delegation, including representatives from the Ministry of Agriculture and research institutions like the Latvian State Forest Research Institute “Silava,” recently participated in an international summit focused on bioeconomy development. This engagement demonstrates that Latvia’s leaders and researchers are already exploring how to transform the country’s bioeconomy potential into tangible economic growth and climate resilience. The discussions focused on how to commercialize pilot projects and strengthen cooperation between industry and research, which is exactly the kind of framework needed to scale biochar production.

Laying the Foundation for a Biochar-Powered Future

To truly harness biochar’s potential, Latvia needs a strategic, multi-pronged approach:

1. Strategy: A unified national biochar strategy is essential. This framework should encourage investment in production facilities and incentivize farmers and foresters to use the product through subsidies, grants, and inclusion in Latvia’s recovery and resilience plan.
2. Feedstock to biochar: Latvia’s abundant 3 million tonnes of annual forestry waste is the primary resource. The next step is establishing a network of biochar production facilities near major timber processing sites. These facilities would use pyrolysis to convert waste into biochar, addressing waste management and reducing reliance on less sustainable disposal methods.
3. End-use targeting: The 0.75 million tonnes of biochar produced annually could be applied across three main sectors:
   • Agriculture: As the largest beneficiary, biochar can improve soil health, increase crop yields, and reduce chemical fertilizer needs, directly contributing to Latvia’s climate goals and enhancing agricultural sustainability.
   • Forestry: Re-integrating biochar into forests could boost tree growth and health, creating more resilient forests that can withstand climate change effects.
   • Water Management: Biochar’s porous structure makes it an effective filter for purifying water by adsorbing pollutants. Latvia could implement biochar filters in wastewater treatment facilities or for cleaning polluted water bodies, improving freshwater quality.
4. Economic and political gain: By utilizing biochar, Latvia could remove 28.8% of its total annual emissions, positioning it as a leader in carbon capture and circular economy practices. This initiative also presents significant economic opportunities, creating new jobs, fostering cleantech innovation, and generating revenue streams. Carbon credits from sequestration could be sold on international markets, further incentivizing the project.

By taking these steps, Latvia has the opportunity to transform its environmental trajectory from a nation grappling with LULUCF sector emissions to a global leader in biochar-based climate solutions. This creates a new model for a truly circular and resilient bioeconomy, serving as an example for the rest of the world.

Key Takeaways:

• Timber industry produces around 11 million cubic meters of timber per year, with an estimated waste volume of around 6 million cubic meters. 
• Timber waste equates to around 3 million tonnes, which could be converted into 0.75 million tonnes of biochar.
• Biochar-based carbon removals could account for over a quarter of Latvia’s total CO2 emissions. 
• Latvia has other key industries outside of forestry, like agriculture, that could benefit from the production of biochar in the region.
