Agricultural activities (e.g., fertilizers, pesticides, and animal waste) are responsible for roughly 30% of total greenhouse gas (GHG) emissions annually. Partnering agriculture with carbon offsets could have a big impact on mitigating climate change. So, we had to ask: what are the best agricultural carbon offsets?

The best agricultural carbon offsets are offered by Husk, Vi Agroforestry, and Native Energy, which involve biochar, agroforestry, avoided grassland conversion, and methane capture projects across the globe. Carbofex and Novocarbo also repurpose waste and CO₂ into biochar and sustainable products.

Keep reading to learn more about the best agricultural carbon offsets, how these carbon offset projects work, what their respective offsetting costs are, and what your best way would be to offset your carbon emissions. At the end of the article, we’ll also share with you what the biggest carbon offsetting limitations are and why reducing your carbon footprint is more effective than offsetting it.

Here’s What All the Best Agricultural Carbon Offsets Have in Common

Carbon offsets are reductions in carbon emissions that are used to compensate for carbon emissions occurring elsewhere. They are measured in tons of carbon dioxide (CO₂) equivalents and are bought and sold through international brokers, online retailers, and trading platforms on what is known as the global carbon offset market. 

“Carbon Offset: a way for a company or person to reduce the level of carbon dioxide for which they are responsible by paying money to a company that works to reduce the total amount produced in the world, for example by reforestation”

Oxford Dictionary

Agriculture is an industry that ranges from small local farmers to commercial grain and livestock operations. It involves soil, crops, and livestock all working together.

“Agriculture: the science, art, or practice of cultivating the soil, producing crops, and raising livestock and in varying degrees the preparation and marketing of the resulting products”

Merriam Webster Dictionary 

Agricultural carbon offsets are a specific type of carbon offset designed to mitigate greenhouse gas (GHG) emissions from agriculture including the addition of fertilizers to soils, manure management, field burning of crop residues, and fuel usage on farms.

“Agricultural carbon credits: increase the storage of carbon from the air into the soil through improved forest, grassland and cropland practices” 

Some examples of agricultural practices that can generate carbon offset credits include:

• Agroforestry
• Soil carbon maintenance
• Methane capture from livestock
• Peatland management
• Livestock and manure management
• Nutrient management on cropland and grasslands

And of these practices, some of the most common agriculture carbon offset projects typically involve:

• Biochar: CO₂ absorbing-charcoal that is formed when biomass (e.g., crop residue, grass, trees, waste) is combusted in the absence of oxygen at temperatures of 300–600°C (572-1112°F). It can be tilled into soils, stored in long-lasting products, buried deep underground, or used as an additive for construction, plastics, paper, and textiles.

• Agroforestry: the integration of trees and shrubs into crop and animal farming systems. Alley cropping, forest farming, silvopasture, riparian buffers, and windbreaks are all examples of agroforestry practices. 

• Avoided grassland conversion to cropland: grasslands are often identified as key areas for conversion to cropland because they account for 20-40% of Earth’s land area and have rich soils. Protecting this ecosystem is crucial to maintaining biodiversity and its carbon storage capacity. 

• Methane (CH₄) capture: Agriculture is the predominant source of methane (CH₄) emissions, which is 25 times more potent than CO₂ at trapping heat in our atmosphere. CH₄ capture from livestock and the installation of anaerobic methane digesters for manure conversion and on-farm electricity generation are common agricultural offset projects.

How Effective and Efficient Are Agricultural Carbon Offsets

In terms of effectiveness, agricultural carbon offsets can store carbon for long periods of time, protect soil health, and reduce methane (CH₄) emissions. However, they can be difficult to monitor and verify, and they do not reduce your own carbon emissions, which can lead to greenwashing.

In terms of efficiency, agricultural carbon offsets are relatively cost-effective; however, they are also not yet scaled to compensate for our global emissions and face storage capacity limitations. 

Agricultural carbon offsets are effective at mitigating climate change because:

• Biochar tilled into soils and not disturbed can store CO₂ for centuries to millennia, making it a long-term carbon sequestration solution.
• Biochar, agroforestry, and avoided grassland conversion can improve soil structure, soil water-holding capacity, and nutrient cycling.
• CH₄ capture from livestock and the installation of anaerobic methane digesters for manure conversion and on-farm electricity generation help prevent CH₄ from entering our atmosphere

However, agricultural carbon offsets can also lack effectiveness because agricultural emissions themselves are difficult to measure and manage, and because purchasing a carbon offset does not directly reduce your carbon footprint. It only makes others reduce their carbon footprint to compensate for your carbon footprint. 

Agricultural carbon offsets are efficient at reducing CO₂ emissions because biochar, agroforestry, CH₄ capture, and avoided grassland conversion are relatively cost-effective, averaging less than $40 per ton of CO₂ offset. 

However, agricultural carbon offsets can also lack efficiency because:

• They are not scaled enough to keep pace with the global GHG emissions of a growing population
• Carbon storage capacity limitations of biochar and agroforestry prevent agricultural offset efforts from compensating for all of our carbon emissions

What Are The 5 Pros and 4 Cons of Agricultural Carbon Offsets

Agricultural carbon offsets can store carbon for long periods of time, protect soil health, reduce methane (CH₄) emissions, are cost-effective, and allow us to reduce carbon emissions in ways we wouldn’t be able to accomplish individually.

However, agricultural carbon offsets can also be difficult to monitor and verify, are not yet scaled to compensate for our global emissions, face carbon storage capacity limitations, and do not reduce your own carbon emissions, which can lead to greenwashing.

What Are the 5 Pros of Agricultural Carbon Offsets

Agricultural carbon offsets have various pros that make them effective at reducing carbon emissions.

What Are the 4 Cons of Agricultural Carbon Offsets

Understanding the drawbacks of agricultural carbon offsets is important in order to effectively mitigate climate change.

How Can Agricultural Carbon Offsets Help Mitigate Climate Change

Climate change is a severe and long-term consequence of fossil fuel combustion. Agricultural carbon offsets can help mitigate climate change because they eliminate fossil-fuel-derived carbon from our atmosphere which, if left untreated, can remain there for tens of thousands of years and exacerbate the negative effects of climate change.

How is Climate Change Defined

Climate change is arguably the most severe, long-term global impact of fossil fuel combustion. Every year, approximately 33 billion tons (bt) of CO₂ are emitted from burning fossil fuels. The carbon found in fossil fuels reacts with oxygen in the air to produce CO₂. 

“Climate change: changes in the earth’s weather, including changes in temperature, wind patterns and rainfall, especially the increase in the temperature of the earth’s atmosphere that is caused by the increase of particular gasses, especially carbon dioxide.”

Oxford Dictionary

Atmospheric CO₂ fuels climate change, which results in global warming. When CO₂ and other air pollutants absorb sunlight and solar radiation in the atmosphere, it traps the heat and acts as an insulator for the planet. Since the Industrial Revolution, Earth’s temperature has risen a little more than 1 degree Celsius (C), or 2 degrees Fahrenheit (F). Between 1880-1980 the global temperature rose by 0.07C every 10 years. This rate has more than doubled since 1981, with a current global annual temperature rise of 0.18C, or 0.32F, for every 10 years. 

As the 2015 Paris Climate Agreement outlines, we must cut current GHG emissions by 50% by 2030 and reach net zero by 2050. 

How Do Carbon Offsets Generally Help Mitigate Climate Change

Levels of carbon in our atmosphere that cause climate change have increased as a result of human emissions since the beginning of the Industrial Revolution in 1750. The global average concentration of CO₂ in the atmosphere today registers at over 400 parts per million. Carbon offsets can help prevent these levels from increasing even more.

When you hear the words “carbon offset”, think about the term “compensation”. Essentially, carbon offsets are reductions in GHG emissions that are used to compensate for emissions occurring elsewhere. 

Carbon offsets that meet key criteria and verified project standards, are additional and permanent, and are a part of projects that are carried out until the end of their lifespan have the best chance of reducing carbon emissions and therefore reducing climate change. 

When we offset CO₂ we also slow the rate of global temperature rise, which in turn minimizes the effects of climate change. 

How Do Agricultural Carbon Offsets Specifically Help Mitigate Climate Change

Agricultural carbon offsets such as biochar, agroforestry, avoided grassland conversion, and farm methane can specifically help mitigate climate change because they all aim to reduce CO₂ emissions, albeit via different pathways. They can also act as permanent carbon sequestration and reinforce our terrestrial carbon sinks.

For example, according to the Intergovernmental Panel on Climate Change (IPCC), biochar alone could potentially remove up to 2.6 billion tons of CO₂ from the atmosphere.

Final Thoughts

The best agricultural carbon offsets are offered by Husk, Vi Agroforestry, and Native Energy, which involve biochar, agroforestry, avoided grassland conversion, and methane capture projects across the globe. Carbofex, Novocarbo, Carbo Culture, Pacific Biochar, and NetZero take advantage of the carbon sequestration properties of biochar. One Tree Planted uses agroforestry methods whereas Terrapass involves capturing methane and generating electricity from livestock manure. 

Agricultural offsets sequester CO₂ and reduce CH₄ emissions, thereby helping to reduce global atmospheric CO₂ and CH₄ levels. But for all of the good carbon offsets can instigate, they should not be seen as the only solution to climate change. They are effective at reducing GHGs in the short term, but in the long term, they fail to reduce GHGs enough. 

When used in conjunction with direct CO₂ reduction measures, carbon offsetting can be much more effective. We should reduce our own carbon footprint as much as possible first, and only then choose the most effective agricultural carbon offsets.
