Mission

Support global enterprises in reaching net-zero by 2050

Through software that makes carbon tracking usable across the entire supply chain.

Problem

Two disconnected tools creating friction

Enterprise teams struggled with a 21-step data upload process, while suppliers had no clear way to input their emissions data.

Goal

Unify the experience for teams and suppliers

Simplify data entry for internal teams and extend the ecosystem to suppliers, all while maintaining accuracy at scale.

Role

Lead UX Designer for enterprise and supplier tools

Redesigning the Footprint Explorer for enterprise users and building the Product Ecosystem for supplier collaboration.

Footprint Explorer

Working alongside BCG's research team, I led the architecture review for the Footprint Explorer — refining navigation, data interaction, and collaboration features through client workshops and card sorting.

The goal was aligning the tool with user needs while meeting environmental compliance objectives.

Initial Research

We conducted user testing on the current UI to identify friction points. You can see the current state of the interface below:

• Original UI •

Testing with end clients revealed a number of consistent friction points:

Interview Findings

Workshop Solutions

Dark colour scheme impacted visual grouping and proximity

Confusion with disconnected CTAs

Visual hierarchy didn't align with core functionalities

Users overlooked essential functions

Main functions lacked clear affordances

Difficult to discern clickable elements

Unclear data relevance

Reduced engagement with the product

Fixed data display area

Frustration — couldn't zoom or expand data views

Information Architecture

Based on testing insights, we restructured the product architecture — focusing on navigation flow, data interaction, and collaboration features.

Streamlined Navigation

The Identify/Discover/Explore phase provides direct access to summaries and data from the homepage, immersing users in relevant information immediately.

Enhanced Data Interaction

The Act phase includes Create Report, Compare, Validate, and Modify Emission Factors — enabling seamless transition from data discovery to actionable insights.

Wireframe Ideation

I translated user research findings into wireframe concepts, exploring solutions for navigation, dashboard customisation, and data visualisation.

Workshop Solutions

Global navigation with local left-hand menu

Intuitive scaling and habitual product use

Customizable dashboard with selectable, minimizable widgets

Interface tailored to specific user needs

Open interface design for data visualisation

Better data presentation and comprehension

Functional components for downloads, filters, saving, sharing

Clear, accessible actions

Data representation options (monthly, quarterly, yearly)

Flexible analysis and data handling

With these enhancements defined, I developed wireframes to visualise the new structure and interactions.

The head office concept focused on visual hierarchy while portraying a zoomed-out view of life — helping leadership understand their role in sustainability. The globe provides a high-level, memorable experience.

Create a Footprint

The Creator was where emissions data entered the system—but the existing process was broken. Users had to navigate 21 steps, upload one file at a time, and constantly backtrack to fix errors. For teams managing carbon data as a secondary responsibility, this was unsustainable.

We streamlined the entire workflow—collapsing redundant steps, introducing multi-file uploads, and building overlay trays to show progress through the process. The goal was to get data into the system faster while maintaining accuracy through human validation.

The Problem

The existing footprint creation process was frustrating and inefficient, with users struggling through a fragmented workflow that offered no visibility into their progress.

Interview Findings

Workshop Solutions

Time-consuming single-file uploads

Users could only upload one data sheet at a time, creating significant delays for teams managing emissions data alongside their primary roles.

Rigid, error-prone workflow

The original process required users to navigate through 23 screens just to create a single footprint, forcing frequent backtracking to correct mistakes.

No visibility into progress

Users had no sense of where they were in the workflow, making the process feel overwhelming and endless.

Original 21-step workflow for creating a footprint

The image is intentionally blurred for confidentiality, but serves to illustrate the sheer number of screens involved in submitting a single footprint.

The Fix

I redesigned the workflow to consolidate steps, add progress visibility, and enable batch uploads — reducing friction at every stage.

Workshop Solutions

Overlay trays for progress tracking

Gave users constant visibility into where they were in the process, reducing cognitive load.

Streamlined workflow

Consolidated steps significantly, cutting down time and frustration.

Multi-file upload

Users could now upload multiple files simultaneously, select cycle years, and rename files in one flow.

Smoother handoff to validation

Direct transitions from data matching to validation, with clear success messages and optional pathways based on user role.

The Flow

The redesigned flow guides users through upload, data matching, and validation with clear progress indicators and streamlined interactions.

Upload Activity Data

Users begin by selecting either activity data sheets (raw emissions data) or emission factor data sheets (verified reference data). Templates are available for download to ensure consistency.

Impact

250%

Process Efficiency

Improvement in overall workflow efficiency, reducing friction and enabling faster data submission.

98%

Successful Completion

Users completing the upload process without errors, significantly reducing validation rework.

Time Saved Per Upload

Internal testing across BCG departments reduced average completion time to approximately 50 seconds.

Seed Funding

CO2 AI raises 12m USD in funding

CO2 AI, a carbon tracking spinout from Boston Consulting Group, successfully raised a $12 million Seed round to build on its momentum in the rapidly growing climate tech sector.

As the Lead UX Designer, I had the privilege of contributing to this innovative project that seeks to revolutionize carbon management and sustainability.
