Seconded, though I'd add that with the current concerns about climate change and resource utilization, we need to think a bit more about product lifecycle and this is a reasonable way of illustrating that.
If the embodied environmental impact of a product increases 10% to make it last 100% longer then we need to think about making that change rather than producing twice as many to replace the broken ones.
