Senior ESG Expertise, Without the Full-Time Hire
I provide fractional ESG leadership for organisations that need senior-level climate and sustainability capability on a flexible basis. My experience spans EY, FoodCloud, Staycity Group, MOSS Earth carbon market development in the Amazon & Lagoa Systems a native AI software provider.
I bring the rigor you would expect from a top-tier advisory team, structured around your needs and timeline.
I work with clients on AI integration, GHG accounting, net zero strategy, science-based targets, carbon market analysis, regulatory disclosure (CSRD, ISSB, CDP), climate training, and life cycle assessment.
Every engagement is built on credible data, defensible methodology, and practical delivery
Core Services
GHG Accounting & Life Cycle Assessment
I deliver comprehensive Scope 1, 2, and 3 greenhouse gas inventories aligned with the GHG Protocol, along with life cycle assessments aligned with ISO 14040, 14044, and 14067.
This includes emissions baselining, data quality assessment, hotspot identification, and embodied carbon analysis across your operations and supply chain.
You get credible, auditable data to meet reporting obligations, identify your biggest reduction opportunities, and disclose your footprint with confidence.
Net Zero Strategy & Decarbonisation Planning
I develop costed, phased net zero roadmaps that translate climate ambition into a practical delivery plan.
This includes decarbonisation pathways across Scope 1, 2, and 3, investment prioritisation, capex and opex requirements, and science-based target setting with full SBTi submission support.
You get a step-by-step plan aligned with your operational and financial realities, not just a target date.
Regulatory Disclosure & Compliance
I support organisations to meet current and emerging climate disclosure requirements, including CSRD, ISSB (IFRS S1 and S2), and CDP.
This covers gap analysis against disclosure frameworks, evidence collation, governance alignment, and preparation for third-party assurance.
Whether you are responding to supply chain requirements or preparing for mandatory reporting, I ensure your disclosures are complete, defensible, and audit-ready.
Core Services
Carbon Market Analysis
I provide independent analysis of voluntary and compliance carbon markets to support strategic decision-making.
This includes credit quality assessment, market trend analysis, integrity risk evaluation, and investment structuring for nature-based and removal projects.
I work with corporate buyers, investors, and development finance institutions to navigate a fast-changing market with confidence and avoid greenwashing exposure.
ESG Strategy & Implementation
I help organisations move from ad-hoc sustainability activity to a structured, credible ESG programme.
This includes maturity assessment, materiality analysis, governance design, policy development, and a prioritised implementation roadmap with assigned responsibilities and timelines.
Whether you are starting from scratch or strengthening an existing approach, I deliver a programme that withstands investor, regulator, and stakeholder scrutiny.
Climate Literacy & Training
I design and deliver tailored climate and ESG training programmes for teams at all levels, from board-level briefings to operational workshops.
Content is built around your sector, your data, and your strategic priorities, not generic slide decks.
Deliverables include pre-training assessment, customised materials, post-session action plans, and completion assessments.
I have delivered training at Irelands leading University - Trinity Business School and across corporate and public sector clients.
NorthStar ESG
I founded NorthStar ESG Advisory to give organisations access to senior climate and sustainability expertise on a flexible, fractional, on demand basis.
Before starting NorthStar, I led climate strategy and carbon accounting programmes at EY, developed the first net zero delivery plan for major Airport Group, built the GHG inventory and climate function at FoodCloud, and delivered Ireland's first embodied carbon report on food waste.
I currently lead carbon market development for nature-based projects in the Brazilian Amazon, serve as fractional Head of ESG for an AI-driven sustainability disclosure platform, and deliver GHG accounting, CDP, and SBTi support for a leading European hospitality group.
I hold a Graduate Diploma in Life Cycle Assessment and Carbon Accounting from University College Dublin (UCD)and an MSc in Climate Change from Dublin City University (DCU). I am a PRINCE2 Practitioner and PMI Agile Certified Practitioner.
I work directly with clients. No junior consultants, no subcontracting. You get the same person in every meeting, on every deliverable.
Mission:
I exist to help organisations turn climate and sustainability data into operational decisions. ESG should sit at the core of how a business plans, invests, and operates, not on the periphery as a reporting exercise. Every engagement I deliver is built around that principle: credible data, translated into action that drives real business outcomes.
