Shaping key features of a carbon accounting platform

Sweep is a data-driven platform that features powerful collaboration tools and a user-focused design. It enables businesses to measure their carbon emissions, empowers them to take action to reduce their carbon footprint, and ensures they stay compliant with the latest reporting standards.


I joined the company's small product design team in its early days to design and shape the core features of the product. Working closely with the co-founders and carbon experts, I aimed to make complex topics accessible to our users.

Designing surveys for companies and employees

Designing surveys for companies and employees

Carbon management is a network problem that requires the combined efforts of your staff and your suppliers.


That's why we've built an internal survey tool to help you choose from a list of existing templates or create your own custom surveys to gather activity data from your employees and partners. I was responsible for designing and enhancing the usability of both the internal survey creator and the customer-facing survey widget.

Creating accurate carbon reports

Your company's decarbonization efforts won't have any effect if the underlying data is not accurate.

My goal was to simplify how users gauge their data's accuracy and easily spot gaps. We implemented key metrics to evaluate data completeness and accuracy, including comparing data points against emission percentages for each category and determining if calculations are based on estimations or physical emission factors.

Managing contributions for climate positive projects

Reducing emissions is a key component of your company's ESG initiatives. However, supporting projects aimed at reducing, removing, or avoiding carbon emissions offers another valuable avenue to contribute to the global shift towards a low-carbon future.


I worked on enhancing the climate projects catalogue, aiming to highlight essential project information and simplify the process for customers to select the most suitable projects for their portfolio.

Choosing the right emission factors

Our clients often struggled to pick the right emission factors for their carbon footprint measurements because there were many large databases available offering similar options.


To address this, I led the redesign of the emission factors catalogue to simplify the selection process. We introduced a "Favourites" feature, and I created a detailed page for each factor, showcasing crucial information to help users decide if it's the right choice.

Customizing user roles and sharing settings

Collaboration is a central feature of our platform. To meet large enterprises' needs, we made it easy for them to manage access and customize user roles, even allowing them to create new ones.


I was responsible for designing the entire user management and permissions feature, ensuring it offered extensive customization and oversight.
