Combatting Climate Change (Goal 13)
The use of biochar has proven to be an effective strategy for combatting climate change, directly aligning with Goal 13 of the UN's Sustainable Development Goals. Here are some key ways biochar contributes to this goal:
Biochar as a Carbon Sink
-
Long-Term Carbon Storage – Biochar is produced through pyrolysis, a process in which organic material is heated in an oxygen-free environment. This method stabilizes carbon, allowing it to be stored in the soil for hundreds to thousands of years. For every kilogram of biochar stored in the soil, approximately 3.5 kg of CO₂ is removed from the atmosphere.
-
Reducing Greenhouse Gas Emissions – Instead of allowing organic material to decompose naturally, which releases carbon dioxide, biochar prevents emissions by locking carbon in a stable form, significantly lowering overall greenhouse gas emissions.
Improved Soil Health
-
Soil Enhancement – Biochar improves soil fertility and water retention, making crops more resilient to drought. It also helps purify soil by binding toxins and pollutants.
-
Increased Resilience – By enhancing soil structure and microbial activity, biochar contributes to stronger, more climate-resilient ecosystems, which are essential for adapting to climate-related challenges.
Economic and Social Benefits
-
Cost-Effectiveness – While the initial costs of biochar production can be high, businesses and municipalities recognize its potential as a cost-efficient solution for reducing climate impact and improving agricultural sustainability.
-
Negative Emissions Strateg - Biochar plays a crucial role in negative emissions technologies, which actively remove CO₂ from the atmosphere—a necessity for achieving global climate targets.
Through these mechanisms, biochar not only helps combat climate change but also promotes more sustainable and resilient agricultural systems. This makes biochar an essential tool in advancing Goal 13 of the UN Sustainable Development Goals
