Complete emissions coverage, zero blind spots.
Scope 1, 2 and 3 emissions tracking is the process of measuring an organisation's complete carbon footprint across direct operations, purchased energy, and the full value chain. Noissime's emissions tracking platform covers all three scopes with guided data collection wizards, automated emission factor matching, and real-time dashboards that give you a complete picture of your carbon impact.
Every scope. Every category. One platform.
Noissime follows the GHG Protocol Corporate Standard to the letter. Each scope has dedicated data entry wizards, validation rules, and emission factor sets, ensuring your inventory is complete and audit-ready.
- Scope 1: Direct emissions from owned sources
- Scope 2: Purchased electricity, heat, and steam
- Scope 3: All 15 upstream and downstream categories
- Market-based and location-based Scope 2 methods
Step-by-step data collection
Each scope has a dedicated wizard that walks your team through data entry. No carbon accounting expertise required -- the wizard asks the right questions, validates inputs, and calculates emissions in real time.
- Scope-specific question flows
- Inline validation and error prevention
- Live emission calculations as you type
- Progress tracking across all categories
Why teams choose Noissime for scope tracking
GHG Protocol aligned
Every calculation follows the GHG Protocol Corporate Standard and Corporate Value Chain Standard. Your data is ready for any audit or assurance process.
15 Scope 3 categories
From purchased goods to end-of-life treatment, Noissime covers every category in the GHG Protocol Scope 3 standard, with specific data entry flows for each.

Complete emissions tracking across every scope
Scope 1 2 3 tracking requires different data sources, methodologies, and validation rules. Noissime handles each with dedicated workflows.
Scope 1: Direct emissions tracking
Scope 1 emissions tracking covers every source your organisation owns or controls. Noissime's guided wizards walk you through stationary combustion from boilers and furnaces, mobile combustion from company vehicles, fugitive emissions from refrigerants and air conditioning, and process emissions from industrial activities. The platform selects the correct emission factors for each fuel type and region, ensuring your Scope 1 emissions tracking is both accurate and audit-ready.
Scope 2: Purchased energy tracking
Scope 2 emissions tracking in Noissime supports both the location-based and market-based methodologies required by the GHG Protocol. For location-based emissions tracking, the platform uses grid-average factors for your country and region. For market-based emissions tracking, it applies supplier-specific factors from renewable energy certificates, power purchase agreements, and residual mix data. Both methods run in parallel, so your scope 1 2 3 tracking dashboard always shows the complete picture.
Scope 3: Value chain emissions tracking
Scope 3 is typically the largest and most challenging part of scope 1 2 3 tracking. Noissime covers all 15 upstream and downstream categories, from purchased goods and services (Category 1) through to investments (Category 15). For supply chain emissions tracking, our supplier automation collects primary data directly from your suppliers, replacing spend-based estimates with actual figures. This moves your Scope 3 emissions tracking from rough approximations to high-quality, auditable data.
Fleet & fuel tracking
Log diesel, petrol, LPG, and electric vehicle data for comprehensive Scope 1 emissions tracking across your entire fleet.
Dual-method Scope 2
Run location-based and market-based emissions tracking in parallel to satisfy every reporting framework simultaneously.
15 Scope 3 categories
From business travel to purchased goods, scope 1 2 3 tracking is complete only when every value chain category is measured.
Supplier primary data
Replace spend-based estimates with actual supplier emissions data for the most accurate Scope 3 emissions tracking available.
Emissions tracking built on rigorous methodology
Accurate scope 1 2 3 tracking demands more than just a calculator. It requires validated data, transparent methodology, and a clear audit trail.
Data quality scoring
Every entry in your emissions tracking receives a quality score. Primary data from meters and invoices scores highest, while estimates are flagged for improvement over time.
Methodology notes
Noissime records the calculation approach, emission factor source, and any assumptions for every line in your scope 1 2 3 tracking, giving auditors exactly what they need.
Validation rules
Built-in emissions tracking validation catches outliers, duplicate entries, and unit mismatches before they reach your final report, protecting data integrity.
Emissions tracking that feeds your carbon reduction plan
Measuring emissions is not the end goal -- reducing them is. Noissime uses the data from your scope 1 2 3 tracking to generate a free carbon reduction plan, included with every paid account. The plan analyses your emission hotspots across all three scopes and recommends specific actions, prioritised by impact and cost-effectiveness.
For Scope 1, your carbon reduction plan might recommend fleet electrification or boiler upgrades. For Scope 2, it could suggest switching to a renewable energy tariff or installing on-site generation. For Scope 3, the plan connects directly to your supplier outreach data, identifying which suppliers to engage first for the greatest emissions tracking improvement.
As you implement actions from the carbon reduction plan, new data flows into your emissions tracking dashboard and progress updates automatically. This closed loop between scope 1 2 3 tracking and reduction planning means you always know whether your strategy is working, and where to adjust next.
