The average Bitcoin transaction is roughly £200,000 with a carbon footprint of 6,625g & bearing in mind it could be sent to the far side of the world, an armoured car carrying gold bars may clock up the same carbon foot print just driving a couple of miles down the road.

Even better 1 lightning transaction or channel opened, may close a year later having performed a virtually limitless amount of transactions ! Now you’re dividing that by 1000s ! We’re talking a carbon footprint of less than an email !
