Abstract: The app aims to raise awareness about the impact of the food choices and alternative methods of making up for that impact. It will calculate the greenhouse gas emission based on the preference of burrito ingredients and it will suggest actions to offset the emissions.
Full Description: There are three widgets in the app:
Burrito builder: Users will use slider bar widgets to input different amounts of ingredients, such as cheese, meat, greens, etc. The inputs will either be in mass units or converted to mass units to match the data we have. Then, using the emission factors from our data, the code will calculate the total greenhouse gas emissions from the burrito, with a bar chart showing the contribution of each ingredient to that total.
Offset Calculator: This tab will have three drop down widgets, allowing users to choose their first, second and third choices for how to offset the greenhouse gas emissions for their burrito. Examples include “bike/walk/skate instead of driving”, “recycle instead of landfill”, and “plant trees”. According to the user's choice, the widget will output how many burritos would equal one standard unit of the offset action. For example, if a user selects “walk instead of driving” the output will show how many burritos would be offset by one hour of walking instead of driving.
Get you burrito: This widget will be a box that allows users to type the first three digits of their zip code. Then, the output will be a map of restaurants that serve burritos in that area. There will also be a drop down widget that will have a list of restaurants in that zip code, which will update based on the input in the first widget - the user can choose one and a table will appear with the different burrito choices at that establishment.
Overall, we want people to know their impact, make conscious decisions. The third widget will be a fun way of showing people that we want them to keep enjoying their burritos but be mindful at the same time.
