Updatable Carbon Impact Calculator
I have a website for a charity to help mitigate individual and corporate environmental impact. I have done the research to find the information on as many variables as I can find, but I need a framework to put them into. More importantly, I need to be able to consistently add new variables based on new and current research.
Users must be able to select a specific time frame to average, from one day to a year, then be able to set up a one-time or recurring payment to a credit card merchant account to mitigate their impact over whatever time frame they wish.
There is a preference for immediate feedback as opposed to requiring user input in order to update the impact of specific behaviors, as increasing individual awareness is the primary concern.
Users must be have the option to create an account of some kind to save their specific inputs for future visits, and I would prefer that there is an option to record non-user-specific data for future environmental research. If possible, this could be integrated with a preexisting shopping cart and credit card processing program.
