In their own words
Arbor
Arbor is a paid carbon accounting platform available through web and API. It measures emissions for products, organizations, and company-owned assets. Product models can cover multiple components, with emissions broken down for parts such as handlebars and tires. The platform calculates product carbon footprints, supports Scope 3 measurement, and assesses fleets and buildings for Scope 1 and 2. Hotspot analysis points to contributors across materials, transport, and manufacturing. Users can compare materials and design choices before production, including through prototyping and versioning. Reports cover product carbon footprint, avoided emissions, Scope 1 and 2, and combined Scope 1, 2, and 3. Arbor says it combines customer data with secondary sources such as LCA databases, trade flows, energy grids, transport routes, and regional material data. It lists Shopify, PLM, ERP, and procurement integrations. Unlimited costs $1,250 a year, billed per month and billed yearly, with three seats.
