Truelabel uses data science to estimate the carbon footprint of products, helping you reduce your impact while you shop without needing a Ph.D. in climate science.
We publish this research because we believe people have a right to know the impact of what they’re buying. We do not take samples or funding from companies. Our research is based on Life Cycle Assessments, the gold standard for evaluating a product’s global warming impact holistically across its ingredients, manufacturing, packaging, etc.
Dish soap is a made up of chemicals and packaging that removes grease and oils from your dishes during washing. Emissions come from various sources, such as from sourcing raw ingredients, mostly surfactants (which come from palm oil, coconuts, or petroleum), and producing the soap in the factory. Then, the soap is packaged, shipped, and used in your sink. All of these steps cause emissions and they can all vary in terms of amount of impact on climate change.
While purchasing the a lower impact dish soap is important, ~96% of the emissions come from heating the water used in your sink! This means having a high efficiency water heater is where you’ll make the most impact, as well as having a clean energy source. If you want to make an even bigger reduction, use cold water for dishes that are not excessively oily. Every reduction counts, and if everyone in the US switched to a less carbon intensive dish soap, we’d save the equivalent of XYZ.
