Green Technology — Prelims Strategy

Prelims Strategy

Read the claim's scope before evaluating the technology. Ask which pressure, which service, which alternative and which life-cycle stages are involved. Reject an option that treats one improved indicator as proof that every impact has disappeared. “Zero tailpipe emissions” and “zero life-cycle impact” are different propositions.

Classify the intervention by its place in the process. Prevention reduces generation of a hazard; treatment handles an existing stream. Collection, sorting and actual recovery are separate steps. A statement about one step cannot automatically establish the completion of the chain.

Practise intensity calculations with explicit output. Divide resource use by useful service and then compare total activity. For original case questions, look for missing maintenance, feedstock or residual-handling information before accepting a universal claim.

In review, explain why each distractor overstates the evidence. This builds a repeatable method for unfamiliar technologies without requiring unsupported assumptions about every new product or a memorised list of promotional descriptions.
