HowGood measures the carbon footprint of an individual product for its entire life cycle, from farm through processing, transportation, manufacturing, product use and disposal. Our Product Carbon Footprinting model and methodology is third-party verified by The Carbon Trust, the world's leading authority on carbon footprinting, as ISO 14067-compliant and aligned to the GHG Protocol Product Life Cycle Accounting and Reporting Standard (referred to as the Product Standard) guidance for GHG emissions measurement and reduction.

HowGood’s Carbon Footprint metrics at each stage of the carbon life cycle have been designed to guide customers on the GHG impacts of their products.

The methodology covers the collection of HowGood’s research data and customer activity data, the mapping of customer activity data to impact data, and the calculation of emissions factors at different stages of a product’s life cycle. The methodology was designed to work with varying degrees of activity data from limited activity data with only product names to detailed data across formulation, manufacturing, transportation, and packaging. In the methodology, we detail here the boundaries of our metrics, assumptions made, exclusions from this analysis, as well as some of the sources and reasoning behind these decisions.
