Carbon removal

Our Green Energy Hubs not only avoid emissions, but actively capture carbon that would otherwise be released into the atmosphere, making them among the most valuable tools in the fight against climate change.

What is carbon removal?

Reaching net zero and keeping global warming below 2°C cannot be achieved by reducing emissions alone. Carbon needs to be removed from the environment and securely stored.

This is known as CCUS (Carbon Capture, Utilisation and Storage) and forms a critical component of government targets.

Biochar manufacture from waste is one of the few proven ways to do this, and scaling this technology is set to become the fastest way to increase CCUS capacity.

Emission reduction vs
carbon removal

Climate conscious countries and organisations around the world are on a path to greatly reduce their greenhouse gas emissions.

However, it is understood that emissions will never disappear entirely, and so to reach Net Zero, those residual emissions must be offset by capturing and storing carbon from the environment.

Currently only around 2% of issued carbon credits are for CCUS and because our feedstocks are bi-products of necessary agricultural and industrial practices, our operations contribute to this all-important category.

What are carbon credits?

Carbon credits are measurable, verifiable emission reductions from certified climate action projects. Projects such as ours are able to qualify for carbon credits as we remove greenhouse gases (GHG) from the atmosphere.

Projects that qualify for carbon credits must adhere to a rigorous set of criteria to pass verification by third-party agencies and a review by a panel of experts at a leading carbon offset standard like Verra or Puro.Earth.

The carbon credits that Onnu generates are not simply for carbon offset, as with traditional waste to energy, but for carbon removal. This external validation means that you can have confidence that your Green Energy Hub is truly working for the planet whilst decarbonising your business.
