Value in Use: CO2 intensities of household items?

We estimate costs and carbon intensities per use for twenty low-utilisation household objects: the average is $13 per use and 1.3kg of CO2, respectively. Both are high numbers.

The biggest determinant is the number of uses per item.  We fear that once purchased by a consumer, the average item on our list will be used just c20 times in its entire lifetime.

More extensive “sharing” will be enabled by drone delivery technologies, potentially saving $150bn of annual sales and 15MTpa of CO2 emissions across these 20 items items alone. Across the entire US economy the savings could reach $1trn and 100MT per year.
