MasterCard Transactions To Be Mined For CO2 Data

seamus1abshere writes "In the latest twist from Big Data, MasterCard and Brighter Planet today announced that cardholder transaction data will be mined for clues about CO2 emissions. Initial coverage will be of flights, car rentals, hotels and other purchases for which the credit card company stores extra metadata. Interestingly, the science behind the offering is all open source."

      Don't worry, the anonymized it by removing your name and address. All they use as an identifier is that random 16-digit number on your card. They have to keep the expiration date as well so they can properly put their data on a time line.

      Mastercard has been giving aggregate data back to its member banks for at least 20 years. This is just another set of aggregate data, but given to corporate card holders. Even if they gave card numbers, names, and addresses, it's only going back to the owners of the cards.

      I worked with Mastercard's data warehouse for 5 years. So if anyone has any questions about what *really* goes on there I might be able to answer (although I can only speculate about this particular program).

    3. Re:Oh, sure. by truthsearch · · Score: 4, Informative

      The short answer is that data is somewhat compartmentalized by department. Each CC transaction first comes through the mainframes, which are very restricted, mostly just for IT. That data is fed nightly to the data warehouse (basically one massive database). A lot of IT get direct access as needed. Some business / reporting applications are then written to query directly from it, limited to the departments that would require it. Any department which needs aggregate data has separate database servers, with data warehouse IT staff facilitating the automatic feed and aggregation of the data.

      Requests for data from outside the company are taken case-by-case. So, for example, when I had to write reports for a particular bank (a Mastercard member), I was careful to only pull that bank's data. I didn't filter anything that was specific to their cardholders. For applications which got aggregate data, individual transactions and CC-specific data was never sent to the application's database servers. It was carefully aggregated first at the warehouse, then transmitted. I have to say there wasn't much general oversight, but it's simply enforced by management throughout the company.

      As I'm sure you noticed from R'ingTFA, this programme basically involves some extra annotation on a system Mastercard's been running since 2002 allowing corporate clients to analyse spending on their cards. So yes, if you're working for Al Gore and spending his money on your company card, he will (shock horror) be entitled to data-mine your transactions for anything he damn well pleases.

  5. Matching products by improfane · · Score: 4, Insightful

    I imagine that the most important piece of information regarding the transaction is the supplier and a transaction number. The amount is worthless. How would you match an amount to a product, especially if more than one product is purchased? Many customers pay different amounts for the same product, how will they factor this in? They'd have to ask the supplier what was actually purchased with some kind of order number.

    Some services are bought but not redeemed later in the future such as a flight or a cruise ship. They need to work out when a servie is actually utilised.

    Somehow I think they'd be better of analysing public transport systems. Such as buses, trains, planes and traffic. If 10 people buy a bus ticket, the bus will expel the same amount of CO2 than if the bus was full. Same with trains, they are quite often under capacity.

      This seems a little hard to believe for a train or a cruise ship or even a bus. I'd buy this on planes though.

      For example, a popular school bus line weighs up to 36,200 pounds (without fuel I believe) and transports up to 90 passengers. In my experience, school buses cram about as many people as possible into the available space and have the lowest level of amenities so I would expect them to have about the lightest weight "per passenger capacity" of any bus. Anyway, this works out to an empty bus weighing about 400 pounds per passenger -- then add the passengers. I would be surprised if adding another 50% (assuming each passenger is 200 pounds - probably high when discussing urban transport where there's no real luggage) weight would result in a "huge" difference in CO2 output between an empty and a full bus.

      I would expect that municipal buses and train cars would have even less discrepancy between their weights when fully occupied vs. empty.

    This is the most idiotic and trollish response that always gets thrown about. Expending energy to figure out how to save energy can easily be a net positive. I'm sure automotive engineers expelled a great deal of energy designing cars that get 30+ miles to the gallon instead of 15. Electrical engineers spent energy designing LED lighting that is far more efficient than incandescent. But you aren't thinking about that, nor are you thinking at all. You're just trolling, because you've been trained to hate anyone who suggests that CO2 can have a negative impact on the climate.

    I find the psychology interesting here. Companies have tracked spending on corporate credit cards since forever; after all, it's their money you're spending, not yours, and they don't want you to spend it on booze and hookers. I don't remember ever hearing anyone complain about the principle of this. But as soon as Mastercard start to offer carbon emissions analysis to their corporate customers -- because 80% of those customers wanted it -- we have a dozen outraged comments about "invasion of privacy" and "the cult of global warming".

    Just try this: storm into the accounts dept. and tell them you're not going to submit receipts for travel reimbursement, because it's none of their damned business whether you rented a hummer or took the train, and if they say otherwise they're members of the cult of global warming.
