What gets measured gets managed—and what gets managed gets reduced.
A carbon accounting tool is software that helps organizations measure, track, and report greenhouse gas emissions across operations and supply chains.
Top tools include Watershed, Persefoni, and Microsoft Cloud for Sustainability, depending on business size and needs.
Scope 3 refers to indirect emissions from supply chains, suppliers, and product usage—often the largest emissions category.
In many regions (like the EU under CSRD), carbon reporting is becoming mandatory for large companies and listed firms.
Costs vary widely—from affordable SME tools like Greenly to enterprise platforms with custom pricing.
Modern tools use AI and verified datasets to provide highly accurate and audit-ready emissions data.
The future lies in AI-driven carbon intelligence, real-time tracking, and automated emissions reduction strategies.
