About Hamerkop Climate Impacts
HAMERKOP IS AN ENABLER - AN INDEPENDENT TECHNICAL CONSULTANCY OPERATING WORLDWIDE.
Headquartered in London & with offices in Singapore, HAMERKOP supports carbon project developers in the Global South and the carbon market ecosystem, to enable emission reductions associated with strong environmental and social integrity. We support energy access and nature-based solutions projects (e.g., forestry and agriculture).
HAMERKOP is one of the very few recognised and independent technical service providers on the carbon market and we mainly work in developing countries, where we provide technical consulting services around 3 main pillars:
1. PROJECT: certification and implementation of projects contributing to the fight against climate change. We help mitigation projects to certify so they can partially or fully be financed by the sale of assets on the carbon markets. We support projects from early conception to early-stage feasibility studies, drafting of carbon certification studies and documents, and support the implementation of activities as well as monitor their ongoing impacts.
2. MARKET: independent expert advice on the carbon markets. We provide (i) technical pre-investment risk-based due diligence to carbon credit and project sponsors; (ii) strategic advice to organisations looking for positioning on the carbon market; and (iii) educational support on the structure, state, and trends of the carbon markets.
3. POLICY: climate change policy and finance. We help countries in the Global South to formulate and revise their climate change strategies and roadmaps. We work with international organisations and government authorities to align their policy, technical and institutional frameworks with the requirements of the Paris Agreement’s carbon and climate finance mechanisms.
HAMERKOP works at the intersection of the public and private sectors, with governments, international organisations, NGOs and private companies and is increasingly playing a crucial role in the Singaporean and Southeast Asian carbon market ecosystem.
We help our clients design, implement, manage and monitor projects and activities in the energy (e.g., clean cooking, transportation, energy efficiency, etc.) and land use sectors (e.g., forestry, agriculture, biochar, etc.), that deliver measurable social and environmental impacts and are eligible to climate finance mechanisms.
