Sector Overview

WONE in
ESG & Impact.

ESG has moved from a reporting obligation to a fundamental driver of capital allocation, regulatory design, and business strategy. The professional services requirements it creates are genuinely multi-jurisdictional — CSRD applies to European entities, TCFD to UK institutions, SEC climate disclosure to US-listed companies, and ISSB standards to entities operating globally. Coordinating compliance across these frameworks requires specialist expertise that most advisory networks have been slow to develop.

WONE Impact is the specialist vertical built specifically for this sector — combining ESG assurance expertise, development finance documentation experience, and south-south capital flow knowledge that most professional services networks lack. WONE's presence in the markets where development capital flows — Africa, Southeast Asia, Latin America — is a structural advantage.

How WONE works Submit a brief
01
CSRD compliance — double materiality assessment and ESRS disclosure
The EU Corporate Sustainability Reporting Directive requires a double materiality assessment, disclosure under European Sustainability Reporting Standards, and third-party assurance — all new requirements for most businesses in scope for the first time in 2025 and 2026.
02
Impact measurement and reporting — IRIS+, IMP, GRESB, SASB
Impact investors and development finance institutions face reporting obligations under multiple impact measurement frameworks simultaneously. Designing a measurement system that satisfies LP reporting, donor requirements, and public disclosure obligations requires specialist advisory.
03
Blended finance structure documentation — combining grant, concessional, and commercial capital
Blended finance transactions combine different forms of capital — grants, concessional loans, first-loss guarantees, and commercial equity — each with its own documentation requirements, governance obligations, and reporting standards.
04
Carbon market participation — credits, offsets, and Article 6
Businesses participating in carbon markets — whether generating credits, purchasing offsets, or engaging with Article 6 mechanisms under the Paris Agreement — face complex legal, tax, and accounting questions that most advisers have not yet encountered.
