The Era of Defossilisation: Beyond Net Zero

The Era of Defossilisation: Beyond Net Zero Introduction For more than a decade, Net Zero has been the defining objective of climate policy, corporate sustainability, and energy transition strategies. It has reshaped investment, accelerated the deployment of renewable energy, and driven remarkable innovation across multiple industries. But as we move into the next phase of the energy transition, an important question emerges: Is Net Zero the destination, or is it a milestone? I believe it is a milestone. The next era will not simply be about balancing carbon emissions. It will be about eliminating our structural dependence on fossil carbon itself. I call this Defossilisation. The Difference Between Net Zero and Defossilisation Net Zero focuses on balancing emissions through a combination of emission reductions, carbon capture, and carbon removal. Defossilisation addresses a deeper question: Why are we continually transferring carbon from geological reservoirs into the active carbon cycle in the first place? For more than a century, humanity has relied on fossil fuels by continuously extracting carbon that has remained underground for millions of years. Every tonne extracted creates an obligation to capture, store, or offset it later. This approach treats the symptom. Defossilisation addresses the source. Carbon Is Not the Enemy Carbon is one of nature's fundamental building blocks. It forms the basis of life, fuels modern industry, and enables countless chemical processes. The issue is not carbon itself. The issue is our dependence on new fossil carbon entering the atmosphere and the active carbon cycle. The objective should therefore be to keep carbon in circulation rather than continually extracting more from geological reserves. A Circular Carbon Economy Just as society has embraced circular approaches for water, materials and waste, carbon should also become part of a circular system. Captured CO₂ should increasingly become a valuable feedstock rather than a waste stream. Combined with renewable hydrogen, recycled carbon can produce renewable synthetic fuels and chemical feedstocks while maintaining compatibility with existing infrastructure. Beyond Technology Competition Today's energy debate often asks whether the future belongs to renewable energy, nuclear power, natural gas or hydrogen. In my view, this is the wrong question. The future belongs to integrated energy systems that intelligently combine renewable generation, energy storage, dispatchable power, carbon recycling, cooling, water management and advanced power electronics. Defossilisation Is a Systems Challenge Achieving Defossilisation requires more than reducing emissions. It requires redesigning the relationship between energy and carbon. Instead of extracting new fossil carbon every day, future energy systems should progressively recycle the carbon already in circulation while renewable electricity provides the energy needed to sustain the cycle. Hydrogen becomes the energy source. Carbon becomes the recyclable carrier. A Practical Path Forward This thinking forms the basis of Carbon Recycling Technology (CRT). CRT is not intended to replace renewable energy or compete with nuclear power. Instead, it complements these technologies by enabling firm, dispatchable energy while progressively reducing dependence on fossil carbon through renewable synthetic methane and continuous carbon recycling. Its objective is not simply lower emissions. Its objective is Defossilisation. The Next Chapter History shows that great industrial transitions begin with a change in thinking before they become a change in technology. The age of fossilisation transformed the world. The age of decarbonisation is reshaping it. I believe the next chapter will be the Era of Defossilisation—where carbon is no longer viewed as waste, but as a valuable resource circulating within a resilient and sustainable energy system. Net Zero has shown us where we need to go. Defossilisation may define how we get there.
