Climate-Friendly Decisions Made Easy

We're trying to help to accelerate the systemic changes necessary to address the climate crisis. We believe that people are essential to creating systemic change, and that if we can get enough people making slightly better decisions, then businesses with the power to influence climate policies and global trends will see the impact to their bottom line, and be motivated to get aggressive with their climate policies and transparent with their data.

Melio’s recommendations represent the best options in terms of both greenhouse gas emissions and company sustainability practices, when compared to similar items. Our CO2 estimates either come directly from the companies or from our own models, which are based on public greenhouse gas datasets and peer-reviewed science. For companies, we consider long-term environmental strategies as well as current sustainability practices, using publicly-available information sources like CDP scorecards, Science Based Targets, renewable energy and green supply chain targets, as well as various certifications for sustainability practices.

When companies publish emissions data, we use it directly. We want to pressure as many companies as possible to do this, but unfortunately there are very few companies that are transparent about carbon footprints today.

When there is no product data available directly from a company, we start with a general emissions estimate based on the product category, sourced from credible entities like ADEME and EXIOBASE. We then augment this initial estimate by modeling product-to-product emissions variations based on secondary product characteristics that we can find on the webpage, such as price, weight, and materials.

Flight emissions estimates use an approach rooted in well-established peer-reviewed science that forms the basis for the modelling used by the International Civil Aviation Organization. It considers a variety of factors which include the flight distance, aircraft type, cabin class, passenger and cargo load factors, holding patterns, and non-aircraft infrastructure emissions, among others.

Our goal is to keep data as anonymous as possible. We want to help you to make better decisions for yourself, but we have absolutely no interest in your personal details. What we do collect is anonymized product data from the websites we support, and anonymized metrics on how you're interacting with our solution. We haven't undergone a detailed security & privacy audit, but our design since day one has prioritized preserving user privacy.
