Shop more consciously with the Klarna app

Greenhouse gas emissions, including carbon dioxide (CO₂e), nitrous oxide (N₂O), and methane are the leading cause of climate change. Usually shown just in lbs of CO₂e equivalents (CO₂e) for easier comparison, almost everything we buy causes these gases to be emitted when it’s produced and shipped.

Tracking emissions gives us a clear and simple insight into our purchase’s impact on the planet. With this tool, you can make informed decisions and get a better understanding of how shopping and emissions are linked.

General principles

We always try to use the most accurate data as possible to calculate the CO₂e emissions estimates per purchase. Given this, if the data is available, we calculate the estimated CO₂e emissions of each single product purchased with Klarna individually (product level estimations). The product level estimations are based on the product category e.g. “cardigan” or “hooded sweatshirt” and, if available, data points like material composition and weight of the product. If the CO₂e emissions of all products of a given purchase can be calculated individually, the sum of the CO₂e emissions of each individual product represents the total estimated CO₂e footprint of that purchase.

What parts of a product’s life cycle are assessed when estimating the CO₂e emissions?

The methodology used covers a complete assessment of the following six stage of a product’s life cycle, often also referred as “Cradle-to-Cradle” approach: Raw Material Extraction, Raw Material Processing, Product Assembly, Deliveries, Use phase of the product and End of life/Recycling. Wherever an emissions breakdown along these life cycle stages is shown, the emissions are attributed to each of the stages depending on the structural characteristics of an average product within the given product category.

By whom are the calculations made?

We’ve partnered with third-party automated software providers to estimate the CO₂e emissions footprint of your purchases.

To monitor our product-level CO₂e emissions, we have partnered with Vaayu. Vaayu offers the world’s first automated carbon software tailored to retailers — their proprietary technology enables retail businesses to track, cut and communicate their carbon emissions. They are providing us with essential tools and data, enabling us to monitor and display product-level carbon emissions in real-time and at scale.
