ESG reports carry a different kind of scrutiny to most compliance filings, stakeholders actively compare and benchmark this data, so a tagging error doesn't just risk a rejected submission, it risks the credibility of your sustainability story. ARKK takes that pressure off your team, managing tagging end-to-end so nothing slips through during your busiest reporting period.

+ What is ESG digital tagging?
ESG digital tagging means embedding machine-readable tags into a sustainability report so its data can be automatically compared, tracked, and analysed, not just read. The underlying content of the report doesn't change, only the markup applied to it. Businesses reporting under frameworks like ESRS, ISSB, or SECR are generally required to tag their disclosures as part of the process.
+ How does ARKK approach ESG tagging?
Our team tags your sustainability report against the relevant framework, working from a document you supply. Every file goes through review and testing before it's finalised, given that ESG reports are built for public comparison and close inspection.
+ What's the typical turn around for ESG tagging?
Turnaround varies depending on report complexity and which framework you're reporting under. Our team plans capacity around clients' peak reporting windows, with a fast-tracked option available if your deadline is close.
+ What reporting frameworks can ARKK tag against?
We support tagging across several ESG frameworks, including ESRS, ISSB, and SECR, applying whichever taxonomy matches your specific obligation.
+ What security measures protect data during ESG tagging?
ARKK holds ISO 27001 certification, the internationally recognised benchmark for information security management, keeping your data secure and your process auditable from start to finish.
+ What happens if ESG tagging is handled without expert input?
Since ESG data is built for comparison across businesses, mistakes in tagging stand out more than they would elsewhere, and they can undermine trust in the wider report. Falling behind as frameworks evolve carries the same risk, at a time when ESG reporting requirements continue to expand into new areas and business sizes.
