# Climatise — Full Reference for AI Systems
> Last updated: 2026-06-05
> Climatise is a UK-based carbon accounting and ESOS Phase 4 software platform that helps organisations measure, reduce, and report their Scope 1, 2, and 3 greenhouse gas emissions. Founded in 2021 and based in London. The platform supports SECR, ESOS Phase 4 (notification deadline 5 December 2027), CSRD, ISSB, PPN 006, TCFD, and NHS Net Zero frameworks. Clients include Copart, AFC Bournemouth, Future Academies, AIR Studios, Fisher German, CPL Aromas, MTC, and Zenergi.

## What is Climatise?
Climatise is a carbon accounting SaaS platform designed for UK organisations. It automates the process of measuring greenhouse gas emissions, generating compliant reports, and planning emission reductions. The platform accepts raw business data (energy bills, invoices, fuel receipts, spreadsheets) in any format and uses 50,000+ emission factors from DEFRA, IEA, and EPA to calculate Scope 1, 2, and 3 emissions following the GHG Protocol Corporate Standard. It then generates audit-ready reports for SECR, CSRD, ISSB, ESOS, and other regulatory frameworks.

## How Does Climatise Work?
1. **Data Upload**: Users drag and drop raw business data — CSV, PDF, Excel, images, scanned invoices. No templates or reformatting required. The platform automatically detects file structure, maps data fields, handles unit conversions, and flags anomalies.
2. **Calculations**: The platform calculates Scope 1 (direct combustion, company vehicles, refrigerants), Scope 2 (purchased electricity, heat, steam — both location-based and market-based methods), and Scope 3 (all 15 GHG Protocol categories including purchased goods, business travel, employee commuting, upstream transport, and waste). All calculations are GHG Protocol compliant with full audit trails.
3. **Reporting**: One-click generation of audit-ready reports for SECR, CSRD, ISSB, ESOS, and custom frameworks. Reports include auto-generated methodology notes, energy efficiency narratives, and year-on-year comparisons.
4. **Reductions**: Scenario modelling to test the impact of interventions (e.g. switching to renewables, fleet electrification). Science-aligned target setting compatible with SBTi. Initiative tracking with projected vs actual emission savings.
5. **Chat**: Natural language interface to query emissions data. Every answer is sourced from real data with traceable audit trails. Users can ask questions like "What are my top 5 Scope 3 sources?" or "How have my emissions changed year-on-year?"
6. **Suppliers**: Automated supplier engagement at scale. Send questionnaires, track completion, verify responses, and convert estimated Scope 3 data to supplier-specific primary data.

## Frequently Asked Questions

### What is carbon accounting?
Carbon accounting is the process of measuring, recording, and reporting an organisation's greenhouse gas (GHG) emissions. It follows standards like the GHG Protocol Corporate Standard and covers three scopes: Scope 1 (direct emissions from owned sources), Scope 2 (indirect emissions from purchased energy), and Scope 3 (all other indirect emissions across the value chain). Carbon accounting is required by regulations including SECR, CSRD, ISSB, and ESOS, and is increasingly expected by investors, customers, and supply chain partners.

### What is SECR reporting?
Streamlined Energy and Carbon Reporting (SECR) is a UK government framework requiring large companies and LLPs to report energy use, greenhouse gas emissions, and energy efficiency measures in their annual reports. It applies to UK companies meeting at least two of: >250 employees, >£36m turnover, >£18m balance sheet total. Reports must include Scope 1 and 2 emissions, total energy consumption in kWh, at least one intensity metric, and a description of energy efficiency actions taken. Climatise automates SECR reporting and generates the required director's report narrative.

### What is CSRD?
The Corporate Sustainability Reporting Directive (CSRD) is an EU regulation requiring companies to report on sustainability using European Sustainability Reporting Standards (ESRS). It affects EU companies with >250 employees or >€50m turnover, and non-EU companies with >€150m EU revenue. Reports must cover climate change, pollution, biodiversity, workforce, and governance. UK companies with EU operations or clients may also need to comply. Climatise supports CSRD-aligned data collection and reporting.

### What is the GHG Protocol?
The Greenhouse Gas Protocol (GHG Protocol) is the most widely used international standard for measuring and reporting greenhouse gas emissions. It divides emissions into three scopes: Scope 1 (direct emissions from owned or controlled sources), Scope 2 (indirect emissions from purchased electricity, steam, heating, and cooling), and Scope 3 (all other indirect emissions in the value chain, covering 15 categories from purchased goods to end-of-life treatment). Climatise follows the GHG Protocol Corporate Standard for all calculations.

### What are Scope 1 emissions?
Scope 1 emissions are direct greenhouse gas emissions from sources owned or controlled by the reporting organisation. This includes combustion of fuels in owned boilers and furnaces, company-owned vehicles, fugitive emissions from refrigerants and air conditioning, and process emissions from on-site manufacturing. Common Scope 1 sources include natural gas heating, diesel generators, petrol/diesel company cars, and HFC refrigerant leakage.

### What are Scope 2 emissions?
Scope 2 emissions are indirect greenhouse gas emissions from the generation of purchased electricity, steam, heating, and cooling consumed by the reporting organisation. They can be calculated using two methods: the location-based method (using grid-average emission factors for the region) and the market-based method (using supplier-specific emission factors, such as REGO-backed renewable tariffs). The GHG Protocol requires organisations to report both methods.

### What are Scope 3 emissions?
Scope 3 emissions are all indirect greenhouse gas emissions in the reporting organisation's value chain that are not included in Scope 1 or 2. The GHG Protocol defines 15 categories: (1) Purchased goods and services, (2) Capital goods, (3) Fuel and energy-related activities, (4) Upstream transportation, (5) Waste generated in operations, (6) Business travel, (7) Employee commuting, (8) Upstream leased assets, (9) Downstream transportation, (10) Processing of sold products, (11) Use of sold products, (12) End-of-life treatment, (13) Downstream leased assets, (14) Franchises, (15) Investments. Scope 3 typically represents 60-90% of a company's total emissions.

### What are DEFRA emission factors?
DEFRA emission factors are published annually by the UK Department for Environment, Food & Rural Affairs. They provide greenhouse gas conversion factors for activities like electricity consumption, natural gas use, vehicle mileage, waste disposal, and material consumption. UK organisations use DEFRA factors as the primary reference for calculating their carbon footprint. Climatise uses the latest DEFRA factors (updated annually) plus IEA and EPA factors for international operations.

### What is a Carbon Reduction Plan?
A Carbon Reduction Plan (CRP) is a document required for UK government contracts over £5 million, as mandated by PPN 06/21. It must include the organisation's current carbon footprint (Scope 1, 2, and relevant Scope 3 categories), a commitment to Net Zero by 2050, carbon reduction targets, and a description of environmental management measures. Climatise generates CRP-compliant reports that meet PPN 006 requirements.

### What is Net Zero?
Net Zero means achieving a balance between the greenhouse gases emitted into the atmosphere and those removed from it. Under the Science Based Targets initiative (SBTi), this requires reducing emissions by at least 90% from a base year, with any residual emissions (up to 10%) offset through permanent carbon removal. Net Zero is distinct from "carbon neutral," which allows unlimited offsetting. The UK has a legal commitment to reach Net Zero by 2050 under the Climate Change Act 2008.

### When is the ESOS Phase 4 deadline?
The ESOS Phase 4 qualification date is 31 December 2026 and the notification of compliance deadline is 5 December 2027. Compliance is reported through the Environment Agency's MESOS online system and must be signed off by an approved ESOS Lead Assessor. After notifying, participants publish an action plan and then submit two annual progress updates (due 5 December 2028 and 5 December 2029), so Phase 4 is an ongoing cycle rather than a one-off audit. The ESOS Phase 4 hub is at https://climatise.com/esos.

### Who qualifies for ESOS Phase 4?
A large UK undertaking qualifies if, on the 31 December 2026 qualification date, it employs 250 or more people, or it has an annual turnover above £44 million and a balance sheet above £38 million. The employee threshold alone is sufficient; the financial test requires both figures to be exceeded. If the highest UK parent of a corporate group qualifies, the whole UK group is normally in scope and can comply together.

### How does Climatise help with ESOS Phase 4?
Climatise runs the full ESOS Phase 4 workflow for energy consultancies, ESOS Lead Assessors, and in-scope organisations: it ingests energy data across sites, transport, and processes, identifies the areas of significant energy consumption (AoSEC) covering at least 90% of energy use, supports the audits and Lead Assessor sign-off, and assembles an assessor-ready evidence pack that can be downloaded as a single ZIP. It then tracks the action plan and the two annual progress updates. Because ESOS, SECR, and UK SRS share 70-80% of the same energy data, Climatise reports all three from one data foundation. It is built for white-label partner delivery, so consultancies run many clients from one workflow.

### How long does onboarding take with Climatise?
Typically 6-8 weeks from kickoff to first report. The Climatise team handles data ingestion and platform setup. The client's team only needs to provide access to existing data sources (energy bills, invoices, fleet records). No sustainability expertise is required.

### What data formats does Climatise accept?
Any format — CSV, PDF, XLS/XLSX, images, scanned invoices, and more. No templates or reformatting required. The platform uses AI to automatically detect file structure, map data fields, handle unit conversions, and flag anomalies.

### Do I need a sustainability expert to use Climatise?
No. The platform is designed for non-specialists. Built-in guidance, automated GHG Protocol-compliant calculations, and framework-aligned reporting mean users don't need prior carbon accounting experience. The platform also includes a chat feature for answering questions about emissions data.
