What is Biochar and Why Do We Need It?

Biochar has the remarkable potential to absorb up to 3 billion tonnes of CO2e every year, which is roughly 6% of the world’s greenhouse gas emissions. We’ve teamed up with Carbon Streaming to explain what biochar is, and why it is considered to be a game changer for carbon removal and sustainable agriculture. 

Biochar’s Big Benefits

To start, biochar—short for biological charcoal—is made by heating organic materials (like agricultural waste, wood chips, or other biomass) in the near or total absence of oxygen, creating a stable form of carbon that resists decomposition and lasts for centuries. Biochar is commonly referred to as “black gold” as it is valuable for many significant reasons, particularly in the fields of agriculture, environmental sustainability, and climate change mitigation. These include:
  1. Acts as a carbon sink: Biochar sequesters and stores atmospheric CO2 in a stable form for hundreds or thousands of years, helping to mitigate climate change.
  2. Improves crop yields: By enhancing soil fertility, water retention, and nutrient uptake, biochar creates a healthier environment for plant growth, leading to higher yields.
  3. Enhances soil fertility: It absorbs and retains nutrients within the soil, making them more accessible to plants and minimizing leaching.
  4. Reduces methane emissions: Biochar promotes soil conditions (Read more…)
