AI DRIVEN

We use AI and automation where it genuinely helps:

Accelerating manual work

Structuring messy data

Identifying issues early

Strengthening auditability

HUMAN EXPERTISE

We rely on human judgement where it counts:

Interpreting results

Defining what good looks like

Engaging suppliers

Guiding organisations towards meaningful change

SUSTAINABILITY FIRST

Because AI also has a carbon footprint, we use it responsibly, selectively and only where it accelerates the path to decarbonisation, by giving teams the clarity, time and confidence they need to drive impact faster.

Features that remove friction strengthen accuracy surface insights support better decisions are built for global teams

AI Data Ingestion

From scattered documents to clean, structured data.

Most organisations spend months producing an annual footprint because their data is spread across PDFs, invoices, bills, spreadsheets and shared drives.

AI Data Ingestion automatically:

Extracts information from structured and unstructured files
Categorises and structures data into usable formats
Flags missing values, anomalies and inconsistencies
Reduces manual copying, pasting and chasing
Supports the most accurate calculation method in line with the GHG Protocol

This means:

Less time spent processing data
Fewer errors and a clearer audit trail
Better insight from reliable, granular data

Supplier Intelligence

Unlock Scope 3 insight faster.

Purchased Goods and Services is often the largest emissions category, yet it is also the hardest to measure accurately.

Our Supplier Intelligence Engine helps by:

Pulling publicly available emissions data on suppliers
Identifying which suppliers have SBTi-aligned targets
Surfacing supplier CDP scores

This reduces friction and improves visibility without endless supplier chasing.

The result:

Faster access to better supply chain data
Improved Scope 3 accuracy
Clearer insight into supplier hotspots and priorities
Hold suppliers to account for the targets you set with them

AI Auditor

A second pair of eyes, built into the workflow.

Instead of manually checking every figure, formula or emission factor, the AI Auditor supports teams by:

Detecting anomalies and unusual variances
Identifying potential double counting
Flagging missing activity data
Highlighting categorisation or boundary issues
Supporting audits with clear, traceable logic

This gives teams the confidence to publish disclosures, respond to stakeholder requests and commit to targets without last-minute surprises.

Automation where it helps.
Human judgement where it counts.

AI can automate the work, but only people can make it meaningful.

Our ISO-certified Climate Success Managers remain at the centre of every client journey. They interpret the data, shape the strategy and help turn insight into measurable progress.

Climate Unlimited™ combines platform automation with expert advisory so clients get the best of both worlds:
