Feel free to add some updated statistics and also a graphical presentation of what those millions of cards would look like, if you had them all together. We would circle the earth a couple of times, if we had all the cards that were manufactured, since it was introduced many years ago. 
Actually no!
The circumference of the earth is 40075 km, the card is 8.5 cm, so that would make around 470 millions cards to do one lap.
So, looking at some of the statistics and considering that those cards must be manufactured with the use of electricity and also destroyed and ending up in landfills, then I would say Bitcoin's carbon footprint must be minuscule compared to this industry.
Let's see you're comparing 149 million cards as a starting point with what?
13 million addresses in the chain with a balance of more than 10$? And that is global!
Let's compare the power consumption of all the bank in the world that serve billions with what? 400k transaction a day?
There are more ATM's and card readers out there, than all the ASIC miners ever manufactured and they use a lot more components to manufacture these devices. 
Of course, let's not count bitcoin atms, those are running on unicorns.
agreed
there are more PC's in banking skyscrappers, bank branches and data centres
more ATM's and merchant card readers

Coinbase has a nice office, binance also, so does bitstamp.
Oh wait, do they have servers and datacenters of their own? Oh wait, those run on carebears! Sorry!
