Effortless Sustainable Shopping-
Chrome Extension + Responsive Website

Global warming is a critical reality, with 2023 being the hottest year on record. Recognizing this urgency, VISA launched a climate tech hackathon to explore green fintech solutions. Our goal was to bridge the intention-action gap in sustainable consumer choices, a shift that could reduce global emissions by 40%.

Every year, global shopping habits contribute to over 60% of greenhouse gas emissions. Yet, most consumers have no idea how their purchases impact the planet. Despite growing environmental awareness and eco-friendly marketplaces, why do shoppers still find it difficult to follow through on sustainable choices?

Problem

Using machine learning and VISA data, ecoScorea Chrome extension that rates sustainability in real time on popular marketplaces and links to a VISA-backed, incentivized, eco-friendly marketplace were built.

Solution

Background

Hackathon Theme: How can VISA expense data be used to identify opportunities for sustainable shopping?

Analyzing 3 years of VISA expense data from 5 urban families revealed high-spending areas: groceries and household items. I then focused on exploring how to encourage sustainable shopping habits in these categories.

Groceries

Household items

Where can sustainable shopping experiences be improved?

I then began exploring existing eco-shopping platforms. Four major platforms were identified through forums, online research, interviews, and AI tools. My goal was to uncover successful strategies, spot market gaps, recognize shopper behavior patterns, and understand the factors that influence eco-friendly shopping habits.

Business opportunities:

  • These eco-friendly brands emphasize natural and earthy aesthetics.

  • Most brands prioritize informal education materials in blogs, but scientific evidence is needed.

  • Most brands only offer limited household items categories without groceries.

I then realized the need to conduct another competitive analysis of popular marketplace websites to uncover where eco-friendly shopping falls short in users’ everyday shopping routine. With similar approach, I identified the four most widely used platforms for groceries and household items.

    • Unmatched variety and fast delivery, with strong personalization through data.

    • Extensive product range, but eco-conscious choices are buried and inconsistent.

    • Lacks clear eco-labeling and filters for sustainable products.

    • Overcrowded UI with overwhelming content hierarchy and too many CTAs.

    • Competitive pricing and accessibility, especially for budget-conscious shoppers.

    • Essentials available at scale, though eco-alternatives are limited or unclear.

    • Sustainability efforts exist but are hard to find or understand on-site.

    • Functional and direct, but visually flat and less intuitive for eco-focused browsing.

    • Strong brand alignment with wellness and eco-conscious messaging.

    • Decent selection of green alternatives, especially in household and personal care.

    • Eco-filtering and sustainability score visibility could be more centralized and interactive.

    • Clean, modern design, though product sustainability info is inconsistent.

    • Convenient and fast grocery delivery across multiple retailers.

    • Product availability depends on partner stores; green labeling is inconsistent.

    • Lacks a unified approach to surfacing eco-friendly choices.

    • User-friendly and efficient, but lacks transparency on eco impact and sourcing.

Business opportunities:

  • Popular marketplaces lack consistent and visible eco-labeling and filters.

  • Most platforms offer limited eco-friendly product ranges.

  • UIs tend to be overcrowded or visually flat.

User Research

Despite eco-consciousness, shoppers need sustainable info, convenience, health benefits, and affordability to follow through

To identify how to boost eco-friendly shopping despite the abundance of marketplaces, I conducted a survey (11 participants). 72% of survey participants struggle to make eco-friendly choices. I also interviewed 5 household shoppers (2 singles, 3 with families), aligned with VISA's user demographics for representative insights.

Shoppers’ Pain Points

We discovered that users needed clear, convenient, timely guidance—without disrupting their shopping experience. This insight became the foundation of ecoScore’s mission: to embed sustainability into shoppers’ everyday behavior, not their to-do list.

Shoppers unaware of product impact, struggle to verify eco-friendly options

Knowledge gap

Price concern

Eco-friendly products are often pricier

Shoppers avoid multiple marketplaces or actively seek eco-friendly products

Convenience

Health benefits

Shoppers prioritize personal health benefits > global impact

How might we seal the gap between groceries and household items shoppers' green intentions & actions?

Rapid ideation for sustainable shopping solutions

Ideation

In response to the How Might We question, I led a timed brainstorming session using quick sketches and team discussions. We identified the first key idea: a Chrome extension that gives you real-time sustainability ratings while shopping online.

The user journey helped clarify the decision to design ecoScore as a marketplace

Sustainable Shopping Journey

Moving along, our team debated whether ecoScore should remain solely a Chrome extension, serve as an educational platform with sustainability scores and knowledge, or evolve into a full marketplace. To fully address user pain points, I illustrated a journey where users navigate from Amazon, use the Chrome extension to assess sustainability, and seamlessly explore eco-friendly alternatives on the ecoScore site.

Eco Product Shopping Task Flow

I then mapped out the step-by-step actions and touchpoints users take to discover and choose sustainable product alternatives when they shop on their familiar online marketplace.

Solution Sketches

Chrome extension + incentivized eco-marketplace

ecoScore promotes sustainable shopping with a Chrome extension that rates products in real time on sites like Amazon for knowledge and convenience. It guides users toward eco-friendly choices on the ecoScore site, which offers insights, discounts, and VISA-sponsored healthy, sustainable products.

Visual Style & Design Choices

Crafting ecoScore’s modern, calm, earth-toned aesthetic

I began ecoScore’s visual identity with a gradient text-only logo to reflect a calm, modern brand rooted in sustainability. The second option was chosen for its balanced shape and subtler colors, best expressing our core values—calm, nature, and health.

Option 1

Option 2

Rooted in and expanded from the logo design, ecoScore’s visual identity uses carefully selected colors, typography, imagery, and iconography to reflect the brand’s core values.

Brand & CTA Colors: The color palette centers on earth-toned greens, chosen for their soothing, natural associations—insights that were reinforced through competitive analysis and user interviews.

Typography: I selected Poppins, a modern geometric sans-serif with rounded letterforms and even spacing, to convey clarity, approachability, and a contemporary feel.

Icons & buttons: Icons and buttons were designed with higher border radius to create a smooth, rounded appearance that feels friendly and inviting. These softer shapes contribute to a cohesive, approachable interface.

Product cards & Imagery: Muted, natural tones and soft lighting were used across imagery to complement the earth-toned palette and evoke a sense of calm and balance. The visuals aim to create an emotional connection with users, reinforcing ecoScore’s message of sustainable, mindful living.

Solution Highlights

1. Convenient and informed shopping

Chrome extension integrates with popular marketplaces, uses a machine learning algorithm to rate product sustainability based on recognized systems like Environmental, Social, and Governance score and guides users toward more sustainable shopping choices.

2. Incentives and sustainable choices

the ecoScore website features high-spending product categories, scientific insights, and VISA sponsorship to support informed, sustainable purchasing decisions.

Final Thoughts

What was accomplished

  • Using VISA finance data to identify groceries and household items as high-spending areas to effectively foster eco-consciousness.

  • Identified limited knowledge, access, and high costs hinder eco-friendly practices. Most consumers, despite environmental awareness, prioritize price, convenience, and personal benefits over seeking knowledge.

  • Developed Chrome extension that integrates with popular shopping platforms with sustainability score & redirects users to our curated earthy aesthetics, VISA incentivized, eco-friendly e-commerce website.

  • Turned the dense scientific information into bite-sized user-friendly product info.

Improvement and Reflection

  • Time management:

    One key challenge in this hackathon project was managing time constraints, which prevented the development of an eco-activity tracking feature that could have further enhanced user engagement and provided meaningful insights into environmental impact.

  • Team efficiency improvement:

    I learned the importance of improving team efficiency through clearly defined roles, creating timelines, assigning a minute-taker for meetings, and documenting plans, progress, and feedback to foster better collaboration and accountability. Additionally, I realized that an over-emphasis on implementation led to insufficient focus on the slide presentation, highlighting the need for a better balance between execution and communication.

  • A stronger business model needed:

    Finally, I also recognized that ecoScore needs a stronger business model. Typical credit card incentives range from 1–5%, but even at the higher end, a 5% VISA reward isn't compelling enough to drive user behavior or differentiate the offering. This insight underscored how crucial a sustainable financial strategy is—not just for user incentives, but also for securing partnerships and sponsorships long-term.

  • This project pushed me to grow beyond just creating beautiful interfaces:

    I learned how to pivot quickly in response to shifting priorities, design with behavioral impact in mind, and ground visual decisions in research-driven insights. Moving forward, I aim to apply these lessons by streamlining design workflows, collaborating more effectively across teams, and delivering solutions that balance user needs, business goals, and long-term impact.
