To quantify that offset

Reusing or recycling these bags significantly offsets their environmental toll by reducing demand for new production.To quantify that offset, we can divide the bag carbon footprint by the number of times it reused.For example, if a typical paper bag is reused three times,it has a lower net impact than a single-use plastic bag.The carbon footprint of a cotton tote can similarly be lowered,if it reused 131 times.Of these three options, durable cloth totes are most likely to be reused.
