The short answer
Making plastic bags uses materials, energy and transport. The impact depends on the bag type, weight, reuse rate and what it replaces.
11:00Anyone saying one bag is always best is probably skipping the hard bit.
11:03Life-cycle comparisons need context.
Why simple comparisons fail
A thin bag used once, a thicker bag reused many times and a compostable caddy liner for wet food waste are not the same product.
11:12Compare the job first. Carrying shopping, lining a bathroom bin and holding food waste are different jobs.
11:20How to choose better
Use fewer bags where possible, reuse durable bags enough times, and choose specialist liners only where the task needs them.
