For many lefties, the banning of plastic bags in our local communities has become a personal cause célèbre that represents a badge of honor in the fight against global warming.
But does the plastic bag “cause” have any scientific merit or is just more anti-science from quacks?
To the math. In the U.S. some 100 billion plastic bags are used each year. Yikes!
On average, it’s been estimated that a plastic bag weighs 32.5 grams (for the record, a typical grocery store plastic bag weighs only 5 grams). And its been estimated that a plastic bag at the average weight represents about 200 grams of CO2 (when accounting for the plastic bag’s production and eventual incineration).
As a result, via simple multiplication, those 100 billion plastic bags equal 20 trillion grams of CO2, which converts to 20 million metric tonnes of CO2.
Sooo…..what’s the plastic bag impact on global warming from 20 million tonnes/year of CO2 over the next 20 years?
Well, it’s squat, too. There is no warming impact, which makes the claim more anti-science propaganda of the quackery sort, this especially true when you consider that California and Nevada County are only a very mapp part of the US plastic bag consumption. I am thinking of bring my own plastic bags to the market.
