Understand Your Supply Chain Scope 3 Emissions
Invite suppliers, collect real activity data, and calculate emissions aligned with the GHG Protocol and SBTi Net Zero Standard — no carbon accounting expertise required.
Connect. Capture. Calculate. Correct.
Scope 3, simplified through C4 — connect suppliers, capture data, calculate emissions, and correct what matters, all in four simple steps.
Connect
Connect suppliers. Invite them with a link — they self-register in minutes, no account setup for you.
Capture
Capture data. Suppliers provide the activity data they already have — no carbon expertise needed.
Calculate
Calculate emissions. Our engine runs GHG Protocol calculations at the best data tier available.
Correct
Correct what matters. Get ranked, actionable steps to cut emissions where the impact is greatest.
What the Platform Does
No vapourware. Each capability turns real supplier data into decisions you can defend.
Customizable Emissions Calculator
Suppliers pick industry, geography, energy type and shipping mode — the engine returns auditable emissions per activity.
Three-Tier Calculation Engine
Supplier-specific, average-data or spend-based — EZScope3 always calculates at the best data tier available and shows which one it used.
AI-Powered Reduction Recommendations
Ranked, actionable steps tailored to each supplier’s profile — flagged verify-before-relying, never presented as guaranteed outcomes.
Net Zero Progress Tracking
Dashboards track emissions reductions over time against your SBTi base year and linear reduction path.
Filing & Disclosure Readiness
Maps your data to GHG Protocol, CSRD/ESRS E1, IFRS S2, CDP, California SB 253, UK SECR and SBTi — and states honestly what you still provide.
Supplier Readiness Levels
A PSCI-aligned maturity ladder from Dormant to Leading shows where each supplier is on its decarbonization journey.
Built on Real Standards
GHG Protocol Aligned
Three-tier calculation hierarchy per the Corporate Value Chain (Scope 3) Accounting Standard.
SBTi Net Zero Ready
Track progress against Science-Based Targets with base-year tracking and 42% linear reduction targets.
Full Transparency
Every calculation shows the emission factor, source, method, and assumptions used — nothing hidden.
