This was made for and submitted as the Final Project for my amazingggg 6-week Stanford CS106 Code-in-Place Class!
The program is super simplistic and rudimentary, but may turn out to be a work in progress since I think a lot of cool impactful stuff can be done with it in the Future. Here's the code:
'''
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ENVIRONMENTAL TRUE COST CALCULATOR
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2020 onward, I believe consumers will start getting more conscious about what they buy and consume.
They will gradually shift from conspicuous consumption to conscious consumption.
One main way this will happen is that companies themselves will choose to, or will have to,
label the true cost of production of their products.
True Cost = $ Price + Litres of Water + Kg. of Carbon (GHG) Emissions
Every Product should be and hopefully will be labeled with it's True Environmental + Economic Cost
