Your command centre for carbon
Stop chasing data in spreadsheets. Noissime gives sustainability managers a single platform to collect, calculate, and report emissions across all scopes with audit-grade confidence.
You're expected to do more with less
Manual processes, fragmented data, and shifting compliance requirements make carbon accounting a full-time job. Noissime automates the grunt work so you can focus on strategy.
What keeps sustainability managers up at night
Data scattered across spreadsheets
Energy invoices, travel logs, supplier data, and waste records live in disconnected files. Version control is impossible and errors compound across tabs.
Manual factor lookups eat hours
Finding the right emission factor for each activity means scouring DEFRA, EPA, and GHG Protocol databases. Matching units and vintage takes hours per month.
Reporting deadlines create fire drills
CDP, CSRD, and internal board reports all demand different formats and disclosure levels. Quarterly deadlines turn into all-hands scrambles every time.
Difficulty proving data quality to auditors
External auditors demand full traceability and documentation. Without audit trails, you're manually reconstructing calculations and sourcing evidence for every figure.
How Noissime solves it
Single platform for all emission sources
Scope 1, 2, and all 15 Scope 3 categories in one place. Upload invoices, travel data, and supplier responses. Everything flows into a unified carbon ledger.
AI-powered data entry and factor matching
Upload a PDF invoice or CSV export. Noissime's AI extracts quantities, matches the correct emission factor, and calculates tCO2e automatically. No more manual lookups.
Automated compliance report generation
One-click exports for CDP, CSRD (ESRS E1), GRI, TCFD, and SECR. Pre-mapped disclosures mean you spend minutes, not weeks, on each reporting cycle.
Full audit trail with data quality scoring
Every figure traces back to source data. Data quality scores show auditors exactly where estimates are used vs. primary data. Export audit packs in seconds.
Purpose-built for sustainability professionals
5,000+ emission factors built in
DEFRA, EPA, IEA, and GHG Protocol factors updated annually. Noissime automatically applies the right factor based on activity type, geography, and reporting year.
Collaborative workspaces
Invite colleagues, facility managers, and external consultants. Assign tasks, track progress, and ensure nothing falls through the cracks during data collection.
Reduction scenario modelling
Model what-if scenarios for solar, EVs, supplier engagement, and efficiency projects. See the impact on your trajectory before you commit budget.
A sustainability management platform built around your actual workflow
Carbon accounting for sustainability managers is more than just calculations. It encompasses data collection from across the organisation, factor matching, quality assurance, stakeholder reporting, and continuous improvement. Noissime is a sustainability management platform designed around the tasks that consume your week.
From chasing colleagues to automated data flows
Most sustainability managers spend a disproportionate amount of time chasing data from facilities teams, finance departments, and procurement. Energy invoices arrive late. Travel data sits in expense systems with no carbon context. Waste records are incomplete. Noissime's carbon accounting for sustainability managers eliminates this friction by connecting directly to source systems and providing self-service upload portals for every data owner in your organisation.
When data arrives, the sustainability management platform validates it automatically. AI checks unit consistency, flags outliers against historical trends, and matches each activity to the correct emission factor from DEFRA, EPA, or IEA databases. This level of carbon accounting for sustainability managers automation means you spend less time on data wrangling and more time on the strategic analysis and stakeholder engagement that actually drives decarbonisation. Every data point carries a quality score, so you always know where primary data is strong and where estimates need improvement.
less time spent on manual data collection
Scope 3 categories tracked in one place
How the supplier funnel saves sustainability managers hours every week
Scope 3 supplier data collection is the single most time-consuming task in carbon accounting for sustainability managers. Noissime's automated supplier outreach funnel transforms this from a months-long email chase into a managed, scalable process built into your sustainability management platform.
Drop suppliers in, get validated Scope 3 data back
Upload your supplier list and Noissime launches an automated outreach sequence. Each supplier receives a free account via magic link, showing only the data fields relevant to their industry and product category, not a daunting fifty-page questionnaire. A facilities management supplier sees questions about energy and waste. A logistics provider sees questions about fleet composition and fuel consumption. This tailored approach dramatically improves response rates compared to generic email requests.
As suppliers respond, their data flows directly into your Scope 3 calculations within the sustainability management platform. AI validates every submission for completeness and accuracy. Automated reminders chase non-respondents on a schedule you control, and cooperation scores let you see at a glance which suppliers are engaged and which need a personal follow-up. For sustainability managers juggling dozens of priorities, this level of carbon accounting for sustainability managers automation is transformative. It replaces weeks of spreadsheet chasing with a dashboard that shows real-time progress across your entire supply chain.
Free supplier accounts
Each supplier gets a free Noissime account with industry-specific fields they can complete in minutes.
Automated Scope 3 integration
Validated responses feed directly into your Scope 3 calculations within the sustainability management platform.
Free carbon reduction plans as ready-made action items
Every paid Noissime account includes AI-generated carbon reduction plans that tell you exactly what to reduce, prioritised by impact and cost-effectiveness. For sustainability managers, these plans are the ready-made action items you need to move from measurement to meaningful reduction.
Prioritised by impact and feasibility
Your free carbon reduction plan ranks every opportunity by tonnes of CO2e saved and estimated implementation cost. Whether it is renewable energy procurement, fleet electrification, or supplier engagement, the sustainability management platform shows the actions that deliver the biggest reductions first.
Board-ready business cases
Each recommendation in your carbon reduction plan includes estimated costs, payback periods, and projected savings. Carbon accounting for sustainability managers becomes easier to justify when you can present leadership with a clear cost-benefit analysis for every proposed initiative.
Aligned to your targets
Your carbon reduction plan maps directly to your SBTi or internal reduction targets. The sustainability management platform shows how each action closes the gap between your current trajectory and your committed pathway, ensuring your reduction strategy is credible and measurable.
Dynamic and always current
As your carbon accounting for sustainability managers data improves and new emission factors are released, your reduction plan updates automatically. New opportunities surface as supplier data arrives and your sustainability management platform captures more granular activity data across every scope.
