Which ESG frameworks are you most familiar with, and how do you choose between them?

My strongest experience is with GRI Standards, TCFD, and the EU CSRD framework, which I have used in combination for a mid-cap listed company. I also have working knowledge of SASB standards and the UN SDG mapping that many companies use to link their reporting to global goals. The choice of framework depends on the audience and the regulatory context. For a European listed company today, CSRD is the regulatory baseline and ESRS sets the disclosure requirements, so reporting has to be built around those. GRI sits well alongside CSRD because the standards are largely aligned and GRI gives more flexibility for voluntary disclosure on topics not yet covered by mandatory standards. TCFD is increasingly embedded within mandatory climate reporting, particularly for financial institutions. Where I have had flexibility, I favour double materiality assessments as a starting point because they force a genuine conversation about what matters to the business and its stakeholders, which produces more credible and decision-useful reports than a checklist approach.

How do you conduct a materiality assessment?

I run materiality assessments as a genuine stakeholder engagement process, not as an internal desktop exercise. The starting point is defining the universe of potential ESG topics, using a combination of sector-specific SASB standards, peer benchmarking, and regulatory requirements. I then map financial materiality: which topics could affect the company's financial performance, risk profile, or access to capital? In parallel, for double materiality under CSRD, I map impact materiality: where does the company have actual or potential significant impacts on people and the environment? Both analyses require evidence, not just opinion. For stakeholder engagement I combine surveys with structured interviews across a representative group: investors, customers, employees, NGOs, and local communities where relevant. I document the process thoroughly because external assurance providers and regulators increasingly scrutinise the methodology, not just the conclusions. The output should be a clear visual matrix and a defensible rationale for every topic that was included or excluded.

How do you manage ESG data collection across a complex organisation?

Data quality is the foundation of credible ESG reporting, and it is also the biggest operational challenge in this function. My approach starts with a data governance framework that assigns ownership clearly: someone in each business unit is accountable for specific metrics, with a named backup. I use a centralised data collection platform rather than spreadsheets wherever possible, both to reduce manual error and to create an audit trail. Before any reporting cycle I publish a data dictionary that defines every metric precisely: what is included and excluded, which emission factors are used, and how estimates are flagged. For Scope 3 emissions in particular I have found that the quality of supplier data is highly variable, so I tier suppliers by spend and emissions materiality and apply different data collection methodologies accordingly. I also run internal data reviews at mid-cycle to catch problems before the deadline rather than discovering them during external assurance.

How do you engage senior leadership and the board on ESG?

Board and executive engagement on ESG works best when I frame sustainability topics in the language of business risk, opportunity, and fiduciary duty rather than environmental or social values alone. I prepare a quarterly ESG dashboard for the board that presents three categories of information: regulatory developments with a direct impact on the business, performance against our own targets with a traffic-light status, and peer benchmarking on topics where our position is materially different from sector practice. I also make a point of connecting ESG metrics to financial metrics whenever the data supports it: the link between employee engagement scores and retention costs, or between energy efficiency investment and operating cost reduction, tends to land more effectively than abstract sustainability arguments. For the executive team I run brief monthly updates with a clear "decision required" section so they are not just informed but actively involved in direction-setting. I have also found that site visits to understand specific sustainability challenges build engagement faster than any presentation.

Tell me about a time you had to challenge a business unit or senior colleague on an ESG claim or commitment they were making publicly.

A business unit director was planning to include in a customer presentation a claim that a specific product line was "carbon neutral" based on a third-party carbon offset scheme we had procured. When I reviewed the scheme I found that the offset certificates were from a project with significant permanence risk: the forestry project had a history of fires, and the carbon sequestration claims had not been independently verified against the Verified Carbon Standard. Publishing a carbon neutral claim on that basis would have exposed us to greenwashing accusations and potential regulatory action under the EU Green Claims Directive. I requested a meeting with the director and brought the technical analysis, not just my concern. I offered an alternative: a statement about our progress on scope reduction with an honest acknowledgment of the offset programme's limitations. The director was initially resistant but ultimately agreed when I explained the regulatory and reputational risk clearly. The revised claim was reviewed by our legal team before publication.

Describe a situation where you had to build an ESG reporting process from scratch.

When I joined my current organisation there was no structured ESG reporting, just ad hoc responses to investor questionnaires and a sustainability page on the website that had not been updated for two years. In my first month I mapped the regulatory requirements applicable to our sector and size, identified the most important voluntary frameworks used by our investor base, and ran a gap analysis against what data we were actually collecting. The gap was significant: we had energy data for our own operations but almost nothing on Scope 3 or social metrics. I built a phased implementation plan: year one focused on getting the foundations right for Scope 1 and 2 emissions and the four or five social metrics that mattered most to investors. Year two added Scope 3 and began the external assurance process. Year three was the first full GRI-aligned report. I kept the process visible to the CEO and CFO throughout by presenting at quarterly strategy reviews, which meant I had executive backing when I needed business units to participate in data collection.

Give an example of how you have used ESG data to influence a business decision.

We were evaluating two suppliers for a major materials contract. The procurement team's initial evaluation was focused almost entirely on price and delivery reliability. I ran a supply chain ESG assessment on both shortlisted suppliers, which included reviewing their published sustainability reports, checking their CDP scores, and conducting a supplier questionnaire on specific risk categories: labour standards in their supply chain, environmental compliance, and data security. One supplier had significantly better Scope 1 and 2 performance and a credible science-based target. The other had recent regulatory violations in two jurisdictions related to wastewater management. I presented this analysis to the procurement director alongside a rough calculation of the reputational and regulatory risk exposure if the second supplier's violations became public. The analysis shifted the recommendation and the first supplier was selected. The contract included a supplier code of conduct and annual ESG self-assessment as standard terms.

How do you approach Scope 3 emissions measurement and reporting?

Scope 3 is the most methodologically complex part of emissions reporting and also the most material for most organisations. My approach follows the GHG Protocol Scope 3 Standard, starting with a screening exercise to identify which of the 15 categories are material for our sector. For a manufacturing business the priority categories are typically purchased goods and services (Category 1), use of sold products (Category 11), and end-of-life treatment (Category 12). For a financial institution, financed emissions (Category 15) dominate. Once the material categories are identified I apply a tiered data collection approach: primary data from major suppliers for Category 1 where spend is significant, spend-based emission factors as a fallback for long-tail suppliers, and activity-based methods for categories like business travel. I disclose the methodology and data quality rating for each category in the report, and I track year-on-year changes to identify where the data is improving and where it is stable. I am also careful to distinguish between absolute Scope 3 reductions and intensity improvements.

What is your experience with external assurance of ESG data?

I have managed two full assurance cycles with a Big Four provider and one limited assurance engagement with a specialist ESG assurance firm. My experience is that the quality of the assurance process depends heavily on the preparation: assurance providers work much more efficiently when the data trail is documented before they arrive. I build an assurance pack in advance that includes the data sources, the calculation methodology, and any estimates or assumptions flagged clearly. I also hold a pre-engagement meeting to agree the scope and the criteria against which the data will be assessed, because scope ambiguity at the start leads to disputes at the end. One area where I have invested significant effort is the consistency of assured metrics over time: changing the methodology for a key metric mid-assurance cycle causes real problems and undermines the comparability that makes assurance valuable. I now lock methodology changes to the start of each reporting cycle and document any changes explicitly in the report.

How do you stay current with the rapidly changing ESG regulatory landscape?

I follow several primary regulatory sources directly: the European Commission's SFDR and CSRD publications, the ISSB standard updates from the IFRS Foundation, and the FCA's sustainability disclosure requirements for UK-regulated firms. I subscribe to the GRI newsletter and the TCFD Knowledge Hub, and I attend the annual CDP technical sessions. For EU-specific developments I use the official EUR-Lex tracker for ESRS updates. I also participate in two industry working groups, one focused on Scope 3 data standardisation and one on social metrics comparability, which gives me early visibility of where regulatory interpretation is heading before official guidance is published. When a significant regulatory development occurs, my practice is to prepare a one-page impact assessment within two weeks that maps the new requirement to our current reporting, identifies the gaps, and proposes a response timeline. I share this with the CFO and General Counsel because ESG regulation is increasingly a legal and financial matter, not just a reporting one.
