What is HowGood’s research methodology for calculating carbon emissions?

HowGood’s methodology for calculating GHG emissions is developed in accordance with the GHG Protocol.

1. Data Collection

HowGood draws on a diverse collection of data sources, including peer reviewed journal articles to calculate the CO2e values for ingredients. For each data source, HowGood performs a data certainty assessment based on the age and comprehensiveness of the findings. This process is completed for every ingredient on which there is accurate and verifiable data.

2. Ingredient Mapping

Once the data is collected and analyzed, HowGood conducts a proprietary process of mapping each ingredient to its source crop, animal or material. Using global import/export data and HowGood industry partnerships, HowGood then maps each source crop to its corresponding geographic location to account for the specific on-the-ground practices, impacts, and risks in each locale. On-farm emissions are multiplied by the ingredient concentration of the product’s ingredient to account for the total amount of material required to grow or raise the ingredient.

3. Data Aggregation

HowGood, to date, has mapped nearly every ingredient, chemical and material (33,000 in total) in the CPG industry, including where and how it is produced. This mapping is used to aggregate data across geographic regions or ingredient categories and develop industry-average impact profiles for CO2e across every ingredient. Based on the ingredient mapping process, HowGood assigns a default location and corresponding industry-average profile for every ingredient in a product. If deeper levels of data granularity are available (from a specific supplier, industry partner, or publication), these specifics are applied.

What data sources does HowGood use to assess GHG emissions?

For GHG emissions, HowGood relies on the International Panel on Climate Change (IPCC) 2013 global warming potential estimates where available and crop-specific LCAs. For crops and locations where no current data exists, HowGood uses supplementary studies and relevant LCAs from proxy locations where environmental conditions and farming methods are deemed as similar.

How does HowGood calculate Scope 3 emissions?

The values provided in HowGood’s Scope 3 Report include emissions due only to sourcing the ingredients tracked within HowGood’s Procurement module. A company may have other sources of Scope 3 emissions due to other operational activities that they should include in their Scope 3 disclosures. The report includes two categories:

  • Category 1: Purchased Goods & Services
  • Category 4: Upstream Transportation

Source: GHG Protocol Technical Guidance for Calculating Scope 3 Emissions

Category 1: Purchased Goods & Services

Category 1 includes emissions from on farm activities, the transportation of ingredients between the farm and the facility where they are processed into ingredients, and the emissions due to the processing of the ingredient itself.

Farm to Farm Gate Emissions

This stage covers GHG emissions due to the growing and harvesting of the material used to create an individual ingredient in a product. The material could be a crop, animal, mineral, or petroleum product. HowGood asks the customer to provide a source location for the crop to provide the best data. If the customer does not know the location where the crop was grown, HowGood uses the most likely location where the crop would be grown.

GHGs are collected at farm gate, which includes all on-farm processes including primary inputs like fertilizer, pesticides, herbicides, and farm machinery fuel needs. On-farm processing, cooling or fermentation, and off-farm cleaning and sorting are included. The farm emissions are then multiplied by the ingredient concentration of the product’s ingredient. We include all of this in xi in the equation above.

Measurements are directly sourced from location and crop-specific Life Cycle Assessments (LCA) from all over the world as well as environmental assessments. Indirect land use change and carbon sequestration are not included at this time.

Transportation from Farm to Processing Facility

To create this metric, we multiply the weight-distance traveled by the emissions factor of the mode of transportation used. We use the Global Logistics Emissions Council (GLEC) standard, a GHG Protocol approved industry source for global transport emissions, as our source for emissions factors. Emissions factors are based on tonne-kilometers converted to kg-kilometers to normalize against 1 kg of product maintained in the HowGood database. HowGood customers don’t always have visibility into the methods and distances of transportation between the farm and processing location so HowGood uses proxy data. 

Transportation distances are calculated using arc distance calculations between state, country, or region centroids. For inter-region transportation, half the distance across the region is used.

Transportation within North America or a single region is assumed to be via truck. Transportation between countries outside of North America is assumed to be via ship. The final transportation emissions between farm and processing facility are then multiplied by the ingredient concentration of the product’s ingredient.

Raw Material Processing into Ingredients

Ingredients are assessed for energy requirements of processing raw materials into ingredients. For example, wheat flour would have all stages of milling energy requirements assessed including washing, grinding, sorting, and sifting (and bleaching when applicable). Excluded from the processing energy value are overhead operations, employee transportation, and manufacturing of the equipment. HowGood then uses the grid mix at the processing location to calculate the associated emissions due to the ingredient processing. HowGood sources these values from papers and reports, LCAs and technoeconomic assessments.

In many cases, as it is with some extracts, or supplements, multiple parts of the processing have been accounted for where industry standards can be applied (ex: for safflower extract applies alcohol solvent extraction/spray drying process). We account for each part of the processing where that information is provided or where we can safely make standard processing assumptions. Where this information is not available or assumptions cannot be safely made, and an ingredient has multiple processing types associated, the most energy intensive processing type is used.

We use region grid mix values to determine how much kg CO2e is emitted per unit of energy. We have grid mix values for US states and most countries and are developing methodology to calculate them for other compound regions (sub-national and supra-national).

Biogenic Emissions

HowGood has conducted extensive research into the types of processing that are associated with different types of ingredients. This enables us to calculate biogenic CO2 emissions from biofuel combustion associated with any processing or manufacturing machinery used to produce an ingredient. This aligns with SBTi, GRI and CDP reporting requirements and industry best practices, which request information relating to biomass/biofuels.

HowGood’s Scope 3 Report includes a line item separating biogenic emissions from your overall Scope 3 (Category 1) emissions.

Category 4: Upstream Transportation

Category 4 covers the transportation of ingredients between the facility where they are processed into ingredients and the facility to manufacture the final product.

Transportation from Processing to Manufacturing Facility

To create this metric, we multiply the weight-distance traveled by the emissions factor of the mode of transportation used. We use the Global Logistics Emissions Council (GLEC) framework, a GHG Protocol approved industry framework for global transport emissions accounting and reporting, as our source for emissions factors. Emissions factors are based on tonne-kilometers converted to kg-kilometers to normalize against 1 kg of product maintained in the HowGood database. HowGood customers don’t always have visibility into the methods and distances of transportation between the farm and processing location so HowGood uses proxy data.

Transportation distances are calculated using arc distance calculations between state, country, or region centroids. For inter-region transportation, half the distance across the region is used.

Transportation within North America and intra-region is assumed to be via truck. Transportation between other regions is assumed to be via ship.
