Overview

Product summary

Review the store description, core capabilities, and common use cases.

PCS (Purchase Control System) is an extension that visualizes the carbon dioxide emissions of products and logistics from online shopping purchases.

Aren’t we wasting money, emitting unnecessary carbon dioxide emissions, and putting a burden on the global environment?

PCS provides the opportunity to determine if a product is worth buying by recognizing the amount of carbon dioxide emitted by the product and its logistics and the number of trees needed to offset the carbon dioxide emissions (in terms of carbon dioxide absorption per year).

Let's use PCS to curb wasteful shopping and unnecessary carbon dioxide emissions and soften our global environmental impact as much as possible.
