When comparing the environmental impact of recipes, the most common metric is “CO2 equivalent” (CO2e), which includes the greenhouse gases that are emitted into the atmosphere during the production and processing of ingredients. CO2e is a more accurate representation of the climate impact of a recipe because it includes all relevant greenhouse gas emissions, like methane and nitrous oxide, not just CO2.
A carbon budget threshold is another common metric and refers to how many emissions can be used before going over the threshold for climate warming. Our Climate Superstar recipes are developed to be 50% below the carbon budget threshold of an average Kiwi dinner*.
HelloFresh has partnered with HowGood to calculate the CO2e impact of ingredients based on the individual amounts of ingredients for each recipe. HowGood has the world's largest database for product and ingredient sustainability, and draws data from hundreds of third-party scientific and peer-reviewed studies to conduct an ingredient-level CO2e impact assessment. We calculate the emissions per serving using HowGood Data sets, including Agricultural Production and Food Processing emission data, based on the precise weight of each ingredient.
Our Climate Superstar recipes are below the carbon budget threshold and have the lowest emissions each week.
