Life Cycle Assessment (GCSE Chemistry)

Which action most reduces resource depletion over the long term?

Which material generally has a higher embodied energy per kg, meaning more energy to produce from raw ore?

Which stage of a product’s life cycle includes mining, quarrying or harvesting the raw materials?

When comparing two functionally equivalent products with LCA, what is the correct term for the agreed basis on which they are compared (e.g., one litre of milk, one LED lamp over 10 years)?

How does recycling aluminium affect its life cycle environmental impact compared with making aluminium from ore?

Which of the following will generally lower the life cycle impacts of a car per km driven?

Which greenhouse gas is particularly associated with fertiliser application and agricultural soils?

Which life-cycle stage includes the energy used by a product during normal consumer use (e.g., washing machine electricity over its lifetime)?

Choosing recycled aluminium instead of primary aluminium most reduces which life cycle impact?

Which end-of-life approach for most polymers typically gives the best combination of resource recovery and lower climate impact (when available and well-implemented)?

Which pollutant from agricultural runoff is most associated with causing eutrophication in lakes and rivers?
