What HAMERKOP ADVISORY LIMITED does

HAMERKOP ADVISORY LIMITED (operating under the trading name Hamerkop, with the primary UK entity HAMERKOP CLIMATE IMPACTS LTD., Company No. 11602397) is a privately held, boutique climate and carbon finance consultancy founded in 2018 by Olivier Levallois. The firm operates from offices in London (40 Bowling Green Lane, EC1R 0NE; also referenced at 60 Grays Inn Road, WC1X 8AQ) and Singapore (108 Robinson Road, #03-01), with a core full-time team of approximately 15–16 staff augmented by a network of sectoral experts. Hamerkop serves carbon project developers, carbon credit buyers and financial sponsors, and government authorities and international organisations in the Global South, with a stated track record of 120+ organisations served across more than 50 countries and 150+ climate finance assignments.

The firm's service offering is structured around three pillars: (1) Projects — technical consulting for climate project certification and implementation across energy access and nature-based solutions, covering feasibility studies, carbon certification document drafting, audit support, implementation and ongoing monitoring; (2) Markets — independent expert advisory on the voluntary carbon market, including pre-investment technical due diligence, strategic positioning and market structure education; and (3) Policies — climate change policy and finance advisory for Global South governments and international organisations to align policy and institutional frameworks with Paris Agreement mechanisms. Underlying capabilities include quantitative risk modelling, GIS and geospatial analytics, and carbon accounting methodology expertise. The firm maintains a proprietary database of 66 active carbon certification standards and has analysed 129 million Verified Emission Reductions across five Southeast Asian countries.

Hamerkop monetises through fee-for-service, project-based consulting engagements on a quote-based model with a free 30-minute consultation as the entry point, and has begun to layer in a subscription/recurring revenue line via the HAMERKOP Academy e-learning platform launched in 2026 (hosted on LearnWorlds). Distribution is primarily direct enterprise sales supported by extensive content marketing (blogs, gated research reports, infographics, free handbooks), LinkedIn community engagement, newsletter and event presence (including London Climate Action Week 2026). The firm is a member of multiple industry associations — the International Biochar Initiative, Biodiversity Credit Alliance, Sustainable Singapore Forest Alliance, ASEAN Carbon Alliance and French Chamber Singapore — and has partnered with Nature4Climate (Reforest Better Guide) and The Art of Forests (Bridging the Disconnect report). The company is founder-controlled, privately held, with no disclosed institutional investment, parent company or subsidiaries.

Expansion highlights5 records

Direct peers

• Climate Focus: Specialised climate consulting and advisory firm supporting public and private actors on carbon markets, NDCs, REDD+ and nature-based solutions with a strong Global South footprint. Directly comparable to HAMERKOP's combined Markets + Policies capabilities.
• Carbonbay: Boutique advisory and rating service focused on voluntary carbon market project quality and integrity. Comparable to HAMERKOP as a specialised, independent VCM advisory for buyers and developers.
• Sylvera: Independent carbon credit ratings and analytics platform serving buyers and investors with due diligence on project quality. Directly comparable to HAMERKOP's Service II (Markets) technical pre-investment diligence, though delivered via a technology platform rather than bespoke consulting.
• South Pole Group: Large carbon project developer and consultancy providing climate strategy, carbon credit advisory, and policy services to corporates and governments. Closely comparable to HAMERKOP across Services I (Projects), II (Markets) and III (Policies), with a similar Global South orientation.
• BeZero Carbon: Carbon credit ratings agency offering independent, risk-based assessments of voluntary carbon credits. Competes head-on with HAMERKOP's Markets/credit due diligence work for sponsors and buyers of carbon credits.
• Climate Advisers: Boutique climate policy and strategy advisory supporting governments and multilaterals on international climate negotiations, NDCs and climate finance. Closely comparable to HAMERKOP's Service III (Policies) Paris Agreement and Global South policy work.

Emerging players

• Renoster: Technology-enabled carbon project analytics and ratings provider for nature-based solutions and engineered carbon removal. Overlaps with HAMERKOP's NbS project work and represents a more tech-enabled competing approach to project certification assessment.
• Carbon Growth Partners: Specialised voluntary carbon market advisory and project development firm with comparable boutique scale to HAMERKOP. Serves as a smaller-scale alternative on VCM project certification and market advisory.

Broad incumbents

• ERM (Environmental Resources Management): Large global environmental and sustainability consultancy with deep climate, carbon markets and ESG advisory practices. Competes with HAMERKOP at the top of the market on corporate and government engagements but operates across a much broader portfolio.
• PwC Sustainability Services: Big Four sustainability and climate advisory practice offering carbon accounting, transition planning and ESG advisory. Competes with HAMERKOP on larger corporate and government mandates where a broad consultancy brand is preferred.
