The Climate Paradox.

CEWT — Principles of Cradle-to-Grave Carbon Accounting Clean Energy and Water Technologies Pty Ltd (CEWT) Technical Position Note | 31 October 2026 1. Purpose To establish a scientifically rigorous, transparent and technology-neutral methodology for assessing the lifecycle environmental performance of energy technologies. 2. Principle One — Thermodynamic Integrity The thermodynamic system, its surroundings and the boundaries separating them must be defined unambiguously. Every assessment must: • Identify all material and energy inputs and outputs. • Apply conservation of mass and the First Law of Thermodynamics. • Account for entropy generation and energy quality in accordance with the Second Law of Thermodynamics. • Include upstream and downstream processes throughout the lifecycle. • Prevent the exclusion or transfer of emissions beyond arbitrarily selected boundaries. Fundamental requirement: No technology should claim an environmental advantage by excluding energy consumption or emissions occurring outside its immediate operational boundary. 3. Principle Two — Equal Accountability for All Carbon Every carbon atom must be accounted for, regardless of whether its origin is fossil, biogenic or atmospheric. The physical behaviour of carbon dioxide does not depend on its origin. One tonne of biogenic CO₂ and one tonne of fossil CO₂ have the same direct atmospheric warming effect when released under equivalent conditions. However, their net lifecycle impacts may differ because of prior atmospheric carbon uptake, land-use changes, regrowth, storage permanence and emission timing. Accordingly: • All carbon inputs, outputs, accumulation and losses must be quantified. • Biogenic emissions must not automatically be treated as zero. • Carbon uptake, release, recycling and permanent sequestration must be reported separately. • Any claimed carbon neutrality must be demonstrated through a complete lifecycle balance. 4. Practical Assessment Framework A consistent cradle-to-grave assessment should include raw material extraction, manufacturing, construction, operation, maintenance, replacement, decommissioning and end-of-life management. The principal evaluation criteria should be lifecycle greenhouse gas emissions, thermodynamic and exergy efficiency, embedded carbon, water consumption and total lifecycle costs. All competing technologies must be assessed using equivalent functional units and clearly stated assumptions. 5. Conclusion Carbon accounting must follow physical science rather than preferential classifications. A credible assessment must account for every carbon atom, every energy input, and every material exchange across a clearly defined system boundary. These principles provide a foundation for evaluating conventional energy, renewable energy, hydrogen, carbon capture, and CEWT's Carbon Recycling Technology on a consistent scientific basis.
