# Scope 3 API

## Introduction

Worldly's Scope 3 tool is a carbon reporting solution that calculates emissions from a company's products and supply chain, enabling sustainability departments to measure, manage and reduce their corporate carbon footprints.

The Scope 3 tool includes generic product models across 38 apparel categories and a library of 27 baseline materials, components and packages. Pre-existing materials and products created through the [Higg Index MSI](/v1.0/reference/higg-msi-api) and [Product Module](/v1.0/reference/higg-product-module-api) can be imported into a Scope 3 library as well.

The Scope 3 API allows you to bring your library of materials, products, purchase orders and supply chain data - as well as the resulting Scope 3 calculations - into a third-party solution such as a carbon accounting or ERP platform. You'll be able to manage these inventories and leverage data across a number of endpoints including:

* **Search** for your Scope 3 materials, products and supply chain assessment data, as well as Higg Index MSI and Product Module objects
* **Import** your previously-created Higg Index MSI and Product Module objects into your Scope 3 library
* **Create** new products in your Scope 3 library, assign custom material compositions, attach purchase orders, link the purchase orders to a supply chain assessment (such as the [Higg FEM](/v1.0/reference/get-fem-module-data)) and ingest Scope 3 carbon impacts in real-time
* **Update** products with new materials, additional purchase orders and specific supply chain assessments

Be sure to reference the [Scope 3 Data Dictionary](/v1.0/docs/scope-3-data-dictionary) for definitions of common fields in an API response, as well as a list of the Scope 3 categories and impacts that are available.

The Worldly Scope 3 API is a JSON query API. All parameters are sent as JSON.
