Every year, thousands of companies disclose through CDP. Disclosure is essential—it provides transparency, builds stakeholder trust, and signals commitment to climate action.

But here's the challenge: disclosure is only the first step. To actually reduce emissions, companies need a way to extend CDP data into full Scope 3 coverage, actionable insights, and future-ready planning. That's where DitchCarbon comes in.

CDP Is a Strong Foundation—but Limited in Coverage

CDP has become an important part of corporate climate disclosure. But its coverage does not reflect the full reality of global supply chains.

Most procurement teams depend on hundreds—sometimes thousands—of suppliers, many of whom may not disclose through CDP. This creates blind spots and slows progress on Scope 3 reduction.

DitchCarbon provides verified emissions data for over 2 million organisations, so procurement, sustainability and finance teams can measure and act on supply chain and portfolio emissions from one source. That means your Scope 3 programme can start with broad coverage from day one.

The Problem With Surveys and Questionnaires

Traditional disclosure relies on supplier engagement: sending surveys, waiting for responses, and chasing data across emails and spreadsheets. It's time-intensive, expensive, and often incomplete.

DitchCarbon takes a different approach. By continuously ingesting and normalising supplier disclosures, we reduce reliance on surveys. Procurement teams can access the data they need without placing the full burden of data collection on suppliers or relying entirely on manual processes.

From Disclosure to Forecasting

Disclosure tells you where you are today. But reducing emissions means looking ahead.

With DitchCarbon, you can model what-if scenarios:

  • How would switching to a lower-emissions supplier affect your targets?
  • What's the impact of a new sourcing strategy on your Scope 3 trajectory?
  • Which categories drive the biggest reduction opportunities?

Our forecasting tools give you a forward-looking view, so you can prioritise real abatement and stay aligned with science-based targets.

Assurance and Trust at the Core

Data credibility matters as much as data coverage. DitchCarbon's Sustainability Information Calculator is independently verified by UL Solutions to ISO 14064-3 under limited assurance.

This provides documented methodology and evidence behind the calculations, helping teams build more defensible emissions reporting.

The Bottom Line

CDP disclosure is essential for transparency and scoring, but it isn't enough to run a Scope 3 programme at scale. Companies need broader coverage, automated data collection, and forecasting tools that turn information into action.

If CDP asks the questions, DitchCarbon gives the answers.
