Tools I Used






Residential carbon emissions account for nearly 36% of global carbon emissions, and 70% of residents want to calculate and reduce their carbon footprint.
*According to U.S. Energy Information Administration (EIA)
Initial Problem Statement/Research Insight?
Research
01
.
After conducting some intense research by talking with 10 users from target audience, I found that there are five major issues with the current tools and processes. These challenges include:
What are the main obstacles to residents reducing their carbon footprints?
01
02
03
04
05
You have to answer 60+ Questions
“Current Practices are too technical”
Tools expect that you know all about your current emissions
“Tools assume that the user knows it all”
lack of Personalization
“Tools lack personal recommendations”
No way to know any progress made
“No motivational aspect to keep going”
Lack of encouragement to turn this to a habit
“Not designed to inculcate sustainable habit formation loop”


To gain expert insights into the challenges and limitations of reducing carbon footprints, I conducted interviews and gathered the following key observations.
But what exactly makes calculating a carbon footprint so challenging?
Observation 01
Observation 02
Observation 03
Observation 04
It is hard to calculate
“ Individual’s footprint unless we know their life style from when they wake up to the time they go back to bed.”
It doesn’t make huge impact
“ However, the potential impact of individual actions is limited, as the majority of emissions stem from industrial sources.”
Controlling emissions is achievable
“ Controlling the emissions we produce is achievable; it simply requires proper education on the subject.”
Experience should be Intuitive
“ Reducing your carbon footprint should be an intuitive experience that encourages the formation of sustainable habits.”

Refined Problem Statement
In what ways can we simplify the calculation of residential carbon footprints to empower individuals to seamlessly adopt, reduce, and sustain eco-friendly habits as a natural part of their daily lives?

After extensive research and refining and redefining the problem statement, it’s the right time to address it. Given the complexity, I’ve employed a unique approach, combining Design Thinking with Creative Thinking to find an Intuitive and value adding solution.

Testing & Refinement
Iteration 01 (Research & Initial Prototype Testing
Iteration 02 (Prototype & Final Design)
Iteration 03 (Usability & User testing)
So, What is a good design without a little bit of critique? As this is just a overview case study, we will just see my iterative design approach for couple of core screens.
Product Testing
03
.
I asked 17 questions focusing on ease of use, functionality and effectiveness
I learned a lot in the process
I Recruited 7 Participants
I tested In-Person
I ran the test for 30 -40 min
I divided the test into scenarios

Splash Screen

Initial Idea
Iteration 01
Iteration 02
Initial Idea
To give users a glimpse of the application's interface and an overview of its functionalities.
1st Iteration Testing Outcomes
2nd Iteration Testing Outcomes
User’s did not understand what the application does and have hard time getting to know it.
Since users had difficulty understanding the application's purpose, I changed the illustrations to real-time in-app content. This change boosted the task completion rate by 70%.

Home Screen
Initial Idea
A place where users can see an overview of all their emissions and a glimpse of different pages.
1st Iteration Testing Outcomes
2nd Iteration Testing Outcomes
-
Lot of users what’s to see their emissions from last month and also for individual days.
-
Majority of users felt that the page is a bit crowded with lot of graphs.
-
Introduced a dropdown that allows users to easily sort their emissions by week, month, and even individual days.
-
Simplified the carbon offsetting section by introducing a streaks view as well.
-
Introduced a component called 'National Average,' which calculates data based on other users and validates individual users' emissions. This update boosted the Usability Score by 7 points.
Initial Idea
Iteration 01
Iteration 02



Initial Idea
After tracking an individual's emissions, the application suggests tips to help reduce them.
1st Iteration Testing Outcomes
After the first Iteration, Multiple user’s felt that the recommendations which the application is giving are very generic and they want personalized recommendations catered to their lifestyle
2nd Iteration Testing Outcomes
Users appreciated the personalized recommendations and believed they would significantly help reduce their emissions. This enhancement also increased the usability score by over 10 points.

I believe that Eco Print has the potential to make a real impact. The 'Human-Centered Design' approach guided every pixel of this project, as I evaluated its potential impact using both collected and predicted data.

of users are predicted to show a noticeable increase in their awareness and reduction of their carbon footprint within one month of using the app.
Bumped up the Usability Score (SUS) from 67% to 86% through 2 rounds of testing.
usability scenarios used to test the application in 2 rounds.

Atomic Habits
How can strong habits be formed? Inspired by James Clear's strategy of incentivizing tasks, I introduced eco coins, which users loved.
Design For A Better Future
“If Design brought us to the place where we are, maybe design has the ability to get us out of it”. This sentence inspired me to start working on this project.
