How DitchCarbon works
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. Numbers you can defend within 2 weeks. Here is the sequence: calculate a baseline from data you already hold, monitor it as it changes, forecast where it is heading, act on what matters most, and bring the organisations you buy from and invest in into the work.

1. Calculate
How does DitchCarbon calculate emissions?
DitchCarbon calculates emissions for each organisation using the most accurate method available for it, whether that organisation is a supplier or a portfolio company. Product and activity data come first. Where neither exists, it falls back to spend, then to industry factors, and it records which method it used for every figure.
- Numbers you can defend within 2 weeks, built from your existing vendor list and spend, with no survey round to wait on
- Product and activity data used ahead of spend wherever an organisation has published it, with the method shown per line
- Every figure carries its source and change history, so an auditor can follow it back
Outcome: you can see which organisations and which categories your emissions actually come from.
2. Monitor
What happens when the data changes?
Figures update as organisations publish new data, so the number in your report is the current one rather than last year's snapshot. Where we do not have good data on an organisation, the gap is shown rather than filled quietly with an average.
- Continuous refresh, with documented sources
- Coverage gaps shown, not hidden, so you know what your total rests on
- Audit-ready reporting for CSRD, ESRS E1, CDP and SBTi, from a calculator verified to ISO 14064-3, limited assurance, by UL Solutions
Outcome: your numbers move when your supply chain and your portfolio move.
3. Forecast
Can you model where emissions are heading?
Model future emissions from current trajectories, published targets and the reductions you have planned. Change an assumption and the forecast moves with it.
- Project progress against SBTi-aligned targets
- Compare reduction scenarios before you commit budget to one
- See which categories and counterparties drift off track first
Outcome: you can plan on modelled numbers rather than last year's total.
4. Reduce
Where should you put the effort first?
DitchCarbon ranks the organisations and categories where a change would move your total most, weighted by what you spend with them or hold in them. That is usually a much shorter list than teams expect.
- Prioritise by footprint and by the leverage you actually have
- Track reduction initiatives in one place, against the baseline they started from
- Measure the change after each action rather than at year end
Outcome: effort goes where the emissions are.
5. Engage
How do you get better data from the organisations you buy from?
Ask for what is missing, not for everything. Because we already hold a profile for over 2 million organisations, most requests are a check and a confirmation rather than a blank questionnaire, and anything an organisation has already published to CDP or EcoVadis can be reused instead of re-entered.
- Request the specific data points still missing, rather than a full survey
- Benchmark organisations against their peers and their industry
- Track commitments and targets, and see who is acting on them
Outcome: the organisations you buy from and invest in do the work once, not once per customer.
You are probably on the other side of this too. If customers or investors send you emissions requests, you can claim your company profile and answer from the same data, once, for everyone who asks.
