The role This is a client-facing role for a carbon and climate practitioner with strong hands-on carbon-accounting experience. You will lead small engagements or own defined workstreams within larger projects, working with colleagues across our international Advisory team to deliver robust analysis and clear, practical recommendations. Your core work will focus on organisational and portfolio-company carbon footprints, covering Scope 1, 2 and 3 emissions. You will work with complex and sometimes incomplete datasets, assess data quality, apply appropriate methodologies and emissions factors, interpret results and help clients identify practical reporting and decarbonisation priorities. You will work primarily with private-markets clients, including GPs, LPs and portfolio companies, alongside selected corporate clients. You will manage day-to-day client interactions within your engagements, lead parts of meetings and workshops, and take responsibility for the quality and timely delivery of your work. Senior colleagues will provide direction and review for complex technical judgements and overall engagement management. A solid grounding in the GHG Protocol and practical experience developing and reviewing carbon footprints are essential. Experience with decarbonisation roadmaps, target setting, financed emissions or climate-related reporting would be valuable. Climate risk, scenario analysis or broader climate-strategy experience would be an additional strength, but the primary focus of the role is carbon accounting, decarbonisation and client delivery. What you will do Client Delivery & Project Coordination Lead small engagements or own defined workstreams within larger carbon and climate projects. Plan day-to-day delivery, coordinate inputs and communicate progress, risks and decisions. Lead parts of client meetings, workshops and presentations, and manage client communication within your workstreams. Bring together technical inputs from colleagues into clear, consistent and client-ready deliverables. Carbon Accounting & Reporting Lead the development and review of organisational and portfolio-company GHG inventories covering Scope 1, 2 and 3 emissions in line with the GHG Protocol. Assess data quality and coverage, select and apply appropriate emissions factors and estimation methods, and document assumptions transparently. Review calculations and outputs for completeness, consistency and methodological accuracy. Analyse year-on-year movements and emissions hotspots, and explain their implications clearly to clients. Support carbon reporting and aggregation at portfolio-company, fund and asset-manager level. Decarbonisation & Wider Climate Advisory Develop practical decarbonisation roadmaps, including reduction levers, priorities, implementation considerations and progress indicators. Depending on your experience, contribute to climate target setting and SBTi alignment, PCAF financed emissions, LCA or product carbon footprints, climate-related reporting, climate risk, scenario analysis or wider climate strategy. Business Development & Growth Support the development of proposals, pitches and other commercial materials. Conduct market and prospect research to support business development activities. Contribute to building and maintaining strong client relationships. Identify potential opportunities based on client needs. Contribute to thought leadership, events and other market-facing activities. Technology & Methodology Development Work with Holtara.io, product colleagues and technical specialists to translate client needs and carbon-accounting methodologies into improvements to calculation logic, data requirements, quality controls and user workflows. Contribute to the continued development of Holtara’s carbon and climate methodologies, templates and service offerings. What you will bring Essential Experience & Capabilities Three or more years of relevant experience in carbon accounting, climate advisory, sustainability consulting or a closely related field. We place greater weight on the depth of your practical experience and level of responsibility than on an exact number of years. Hands-on experience developing and reviewing Scope 1, 2 and 3 GHG inventories in line with the GHG Protocol. Practical experience assessing data quality, applying emissions factors and estimation methods, documenting assumptions and resolving calculation issues. Strong analytical skills and confidence working with complex datasets. The ability to independently manage defined workstreams, review technical outputs and turn analysis into clear client deliverables. Clear written and verbal communication skills, sound judgement and confidence working directly with clients and specialist colleagues. The ability to manage multiple priorities and work effectively in an international, multidisciplinary environment. Experience That Would Be Valuable Developing decarbonisation roadmaps or supporting climate target setting and SBTi alignment. PCAF financed-emissions calculations, LCA or product carbon footprints.
