Carbon negative

Carbon negative is often used in the context of efforts and technologies that capture and store more carbon dioxide than they emit, forming a net reduction in the amount of this greenhouse gas in the atmosphere. For example, certain bio-energy technologies can be carbon negative if they utilize biomass that, as it grew, absorbed more carbon dioxide than is emitted during the energy generation process.

In recent years, much focus has been directed towards carbon negative solutions in the fight against climate change. This was borne out of increasing calls for carbon accounting strategies that not only aim for net-zero emissions but also actively reduce existing atmospheric carbon dioxide. Such solutions often involve capturing carbon dioxide directly from the air or enhancing natural carbon sinks such as forests and oceans.

Many renewable energy sources like wind and solar are `carbon neutral`, meaning they don’t produce carbon dioxide in operation. However, to be considered carbon negative, an activity or process must remove more carbon dioxide than it produces. This is often achieved through carbon capture and storage techniques or carbon sequestration activities such as reforestation.

While concepts like carbon neutrality are frequently targeted as minimum standards in environmental policy, carbon negativity sets a higher bar, demanding not just a stop to climate damage, but the reversal of it. Consequently, carbon negative approaches imply a more sustainable and regenerative interaction with the planet’s environment and ecosystems, and signify a proactive commitment to combating climate change.
