Who we are

Portra Consulting
Portfolio Transition & Net Zero Advisory

We partner with organisations navigating the transition to Net Zero — from portfolio-level strategy and disclosure readiness to programme design and delivery oversight. Our work combines analytical rigour with practical governance so capital, teams, and timelines stay aligned to the transition plan.

What we do

  • Organisational Net Zero & GHG Strategy — inventories, scope 1–3 analysis, science-aligned targets, and governance.

  • Real-Asset Portfolio Transition Programmes — portfolio diagnostics, scenario modelling, investment prioritisation, and programme oversight.

  • Asset-Level Decarbonisation Plans — benchmarking, phasing, and CAPEX roadmaps to reach operational Net Zero.

Our approach

  • Independent & material — we focus on what moves the needle, not what fills a slide deck.

  • Data-led & decision-ready — clear assumptions, scenarios, and trade-offs tied to budgets and risk.

  • Governance first — roles, rhythms, and reporting that survive leadership changes.

  • Pragmatic delivery oversight — we don’t promise savings; we make sure the plan is deliverable and financeable.
