First DMA or next one? Both start here.

This is my first DMA

Karomia identifies your impacts, risks and opportunities (IROs) for your own company, and you can trace every result back to its data.
You validate and adjust the IROs, then consult your stakeholders.
Karomia turns the result into a compliant output, fully customisable.

I already have a DMA

New

Bring your existing DMA. We use it as your starting point.

Why it matters

The foundation of every sustainability report you write

A double materiality assessment looks both ways: how your business affects people and the planet, and how sustainability issues affect your business. What comes out sets the scope of your CSRD report and tells you where your strategy should focus.

Get it right, and every report after it gets easier. Get it wrong, and you report on the wrong topics, or fail the audit.

A DMA refresh feels like starting all over.
Again.

Weeks of desk research, all over again

Every stakeholder surveyed from scratch

What if your next DMA practically runs itself?

Everything a solid DMA needs, built in

All your impacts, risks and opportunities, identified for you

Karomia analyses your operations and full value chain, then lists your actual and potential impacts, risks and opportunities (IROs). Everything follows the EFRAG guidelines, so the process you follow is aligned and ready for the auditor’s review.

Not a list to tick a box, but an in-depth view of your company, with every IRO linked to its evidence and sources.

Get stakeholder feedback effectively

Your stakeholders’ input matters, but you also want to keep it pragmatic. Don’t waste anyone’s time. Share short surveys in any language, run interviews or focus groups. All input is stored securely for the audit and gives you a live view of the materiality outcome.

Trusted by auditors, built for strategy

Karomia’s DMA method has been audited more than 30 times, by every Big Four audit firm. We know first-hand what auditors look for and guide you through it in the platform. Even if you only refresh your existing DMA, it stays fully compliant.

DMA refresh

Your second DMA should not feel like your first

Many companies have already done a DMA. Updating it should not mean starting from zero. We start from your current assessment, whether you did it in Karomia or in a big spreadsheet.

01

Start from what you have

Pick your past DMA in Karomia, or upload your existing DMA. Karomia’s deep-search engine then uncovers all new and updated impacts, risks and opportunities. These can come from a change in your activities, new scientific insights or simply more transparency in your value chain.

02

Re-engage with stakeholders to drive deeper

Once you have the updated IRO analysis, re-engage your existing or new stakeholders to collect their feedback, and see the refreshed results roll in.

03

See and understand the updates live

Arrows on your materiality matrix show which topics moved up or down since your last assessment. For each topic, you see the result before, the result now, and the reason for the change.

From DMA to your CSRD report

Your DMA sets the scope of your CSRD report

Your CSRD report covers what is material to your company. In Karomia, the results of your DMA become the scope of your ESRS report: the standards and the data points you report on.

Your material topics set the ESRS standards in scope
The disclosure requirements to report on follow from them
Your results flow straight into the report, nothing typed twice

Questions we hear a lot

Don't see your question? Talk to our team, we're happy to help.

Things change: your activities, your suppliers, the rules. A refresh keeps your assessment current without starting over.

Yes. Fill in our template with your topics, subtopics, scores and the reasoning behind them. Adding your IROs is optional. Then upload it.

No. You and your stakeholders score again, based on where your business is today. We then show you how the results compare with last time.

Your first list of impacts, risks and opportunities is ready within hours. Most companies complete their assessment, stakeholder input included, in days rather than months.

Karomia’s DMA method follows the EFRAG guidelines and has been audited more than 30 times, by every Big Four audit firm. Every IRO is linked to its evidence and sources, so your auditor can trace each result.
