A carbon credit is a market-based mechanism that aims to reduce greenhouse gas emissions by creating a market for carbon offsets. By allowing companies to buy and sell carbon credits, the mechanism aims to create a financial incentive for reducing emissions and increasing energy efficiency.

Carbon sequestration is the process of capturing carbon dioxide from the atmosphere and storing it in a long-term storage location, such as underground geological formations, oceans, forests, or soil. This process helps to mitigate climate change by reducing the amount of carbon dioxide in the atmosphere.

MRV stands for Measurement, Reporting, and Verification. In the context of carbon emissions, MRV refers to the process of measuring and reporting greenhouse gas emissions, as well as verifying the accuracy of those measurements. MRV is an essential component of carbon emissions trading, as it helps to ensure that emissions reductions are accurately measured and reported.

SDG stands for Sustainable Development Goal. The SDGs are a set of 17 goals adopted by the United Nations in 2015, with the aim of promoting sustainable development and ending poverty. The goals cover a wide range of issues, including climate change, gender equality, and access to education and healthcare.

ESG stands for Environmental, Social, and Governance. ESG factors are used to evaluate the sustainability and ethical impact of investments. Environmental factors include things like climate change and resource depletion, while social factors include issues like human rights and labour standards. Governance factors include things like board diversity and executive compensation. ESG investing seeks to promote positive social and environmental outcomes while generating financial returns.

CAS exists because 20% of the world’s carbon emissions come from agriculture – and we want to change that with our products.

We are the first-ever digital MRV developed specifically for soil carbon. We use world-first technology to measure the carbon content in soil and report it digitally (no one else is doing this). This means a quicker, more transparent and precise supply of carbon credits that can be reported to the market.

Traditional methods measure Organic Carbon

Traditional soil carbon measurement uses combustion technology, which cannot distinguish between organic and inorganic carbon. The standard approach addresses this by treating soil with acid to dissolve carbonates, then measuring the remaining organic fraction. ⚠️ However, this acid treatment is problematic. The process requires 24+ hours of soaking, making it impractical when analyzing many locations. More fundamentally, the process is unreliable - it takes multiple acid baths to fully remove inorganic C; Moreover, destroying all carbonate while preserving organic C is extremely difficult.

At Carbon Asset Solutions, we measure Total Carbon

In most agricultural soils, inorganic C remains remarkably stable over the timescales we're measuring (decades to centuries). Climate conditions that significantly alter soil inorganic C operate over millennia. The only mechanism that could substantially change landscape-level inorganic C within decades would be soil erosion removing high-organic topsoil. But this would reduce total C, not increase it, so it's already captured in our measurements. 💡 What we need for carbon sequestration measurement - and for Scope 1, 2, and 3 reporting - is the change in total soil C. Since inorganic C doesn't meaningfully change over the measurement period, the change in total C accurately reflects the change in organic C. It's simply a matter of subtraction between starting and ending measurements. Put another way: if you're losing or gaining organic C through management changes, the total C measurement will capture this regardless of the background inorganic C level. A high inorganic C level just means a larger baseline - the delta still reflects sequestration. Hence, should we measure total carbon or organic carbon only? Total carbon is our go!
