Sustainability Advisory

Senior counsel for the decisions that matter

Some questions do not need a workstream, they need a straight answer from someone who has seen the situation before. Our advisory practice supports boards and executives at decision points.

  • Board-level
  • Transaction support
  • Independent view

Engagements

Where we are typically brought in

Short, senior engagements with a defined question and a written answer at the end.

  • Independent review of an existing net zero strategy or public commitment
  • Climate and ESG due diligence for acquisitions and investments
  • Readiness assessment ahead of a new disclosure obligation
  • Second opinion where internal teams and external advisers disagree
  • Board and executive education on climate risk and regulation
  • Interim sustainability leadership during a hiring gap

Practice areas

What we advise on

  • Strategy review

    An honest assessment of whether your current plan will deliver the target you have published.

  • Transaction diligence

    Climate liability, transition risk and disclosure exposure assessed within deal timelines.

  • Regulatory readiness

    What a new obligation actually requires of you, and what it does not, before you over-invest.

  • Board education

    Briefings that give non-executives enough grounding to ask management the right questions.

  • Claims review

    Pre-publication review of environmental claims against greenwashing and regulatory risk.

  • Interim leadership

    Experienced sustainability leadership on a temporary basis while you recruit permanently.

Questions

Advisory questions

  • How are advisory engagements structured?

    Usually as a fixed-scope piece with a defined question, an agreed set of interviews and document reviews, and a written output. Most run between two and six weeks.

  • Will you tell us if our strategy is not credible?

    Yes, and in writing. An advisory engagement that only confirms what management already believes has no value. We would rather lose follow-on work than sign off on a plan we do not think will hold.

  • Can you advise if we already have another consultant?

    Frequently. A genuinely independent second opinion is one of the more common reasons clients engage us, particularly where the incumbent adviser also stands to deliver the resulting work.
