Most carbon plans optimise what companies can see.
The largest emissions hotspot may sit in raw materials, product design or the supply chain.
My guest is John Beath, CEO and Chief Technical Director of John Beath Environmental. John helps companies use lifecycle assessment and product carbon footprints to identify where emissions actually arise—and where intervention is worth the cost.
Pressure to report Scope 1, Scope 2 and Scope 3 emissions is rising, while climate budgets, engineering time and supplier leverage remain finite. A company can produce a polished carbon inventory and still make a poor decision if its system boundary excludes durability, avoided emissions, waste, transport or the energy embodied in raw materials. Carbon accounting should guide action, not reward whatever is easiest to measure.
One reusable water bottle derived roughly 90% of its cradle-to-grave footprint from raw materials, leaving factory improvements with little room to move the total. Bio-based packaging was not automatically better: John says only about half of the alternatives his team assessed outperformed conventional materials once energy, weight and performance were included. A solar-panel manufacturer assumed silicon was its principal carbon problem. Lifecycle assessment pointed instead to the aluminium frame; changing the frame material reportedly cut the panel’s footprint in half.
We also examine a difficult accounting paradox: companies building solar and wind assets can raise their operational footprint through construction, even while reducing emissions across the wider electricity system. Measure too narrowly and the accounting can punish activity producing the climate benefit.
This is not about collecting more carbon data for its own sake. It is about drawing the right boundary, testing assumptions, adding cost and durability to the analysis, and making claims that can survive third-party scrutiny.
This will be useful for sustainability leaders, procurement teams, manufacturers, policymakers, investors and anyone turning emissions data into defensible business decisions.
If you use lifecycle assessment or product carbon footprints in practice, I would be interested in where the data has most challenged your assumptions.
