😎 Biochar: an up-and-coming heavyweight in carbon credits. But why is it suddenly becoming so damn popular? For starters, it opens new pathways to a circular economy. What is biochar and how is it made? When organic plant matter (biomass) decays in a natural environment it releases stored CO₂. Turning biomass into biochar prevents the process of decay, creating permanent storage for CO₂. We do this by pyrolysis (heating the biomass at high temperatures in a low oxygen environment). The resulting biochar is nutrient-rich and so can be used as a fertiliser to improve soil health – and increase crop yields. Category Type 5 of the Oxford Offsetting Principles (carbon removal with long-lived storage) Evaluation 🧓 High durability with carbon being stored for 100+ years 🚮 High additionality by using waste biomass ⚖ High measurability as it’s possible to measure the carbon content of the biomass being used ‼ Some risk due to a lack of research into the negative environmental consequences of spreading biochar 😍 High co-benefits from using the end-product, i.e. biochar Example climate projects featured in Lune’s curated library: 🧻 Wakefield BioChar: manages waste products from a pulp and paper mill to store 2.9 tCO₂ per tonne of biochar for hundreds of years. 🥜 Pyrocal: uses waste from organic feedstock such as macadamia shells and used pine wood pallets to create high-quality biochar. Each ton of biochar is over 80% pure carbon and safely stores 2.9 tCO₂ for hundreds of years. Bonus fact: Did you know it’s also the only carbon removal you can use in cat litter 🙀 What’s the most intriguing use of biochar you’ve heard of so far? #CarbonOffsetting #Biochar #CircularEconomy #ESG #ClimateProjects

Great insights! Carbon stored for +100 years... that is real impact! 😍 🍀
