Request for Consultation


The client wanted to build a responsive application that can display the total CO2 emitted by the user’s vehicles and the total number of trees required to compensate for the emission of CO2. Users need to enter their vehicle type and total miles traveled to get the total CO2 emitted. The application also enables users to make payments to the admin and the admin will plant trees on behalf of users.

The app has built-in 5 fuel types, 28 vehicle types, and their fuel efficiency to calculate CO2 emitted by vehicle type. It provides users with 2 units- English and Metric. If the user selects English, then distance will be in miles and CO2 will be in lbs. If the user selects Metric, then distance will be in km and CO2 will be in kgs.  The user can view their history allowing them to keep track of CO2 emitted and trees planted by them.
