Green Project Technologies is part of ACT Group, who is the world’s leading provider of market-based sustainability solutions with over 70 products in 40 plus countries including Amsterdam, Shanghai, New York, Paris, Tokyo and Singapore. 

About the role 

Join Green Project as a Carbon Accounting Associate (Japan Market) and be a part of a fast-growing, remote-first climate tech company that's empowering businesses of all ESG maturities to kickstart or deepen their commitment to sustainability. As a crucial member of our Customer Success team, you'll be at the forefront of both (i) externally defining, quantifying, analyzing and reporting on our client’s GHG footprints, and (ii) internally bolstering our methodological rigor, breadth of disclosure, and data management processes. By overseeing clients’ GHG inventories end-to-end, offering targeted, right sized decarbonization advice, and shaping our growing practice at Green Project, this role provides unparalleled exposure to the burgeoning field of carbon accounting and opportunity for upward mobility and personal ownership. 

In essence, your role involves:

• Own a portfolio of customer accounts, managing the full post-sales lifecycle: onboarding handoff, adoption, renewals, and expansion
• Guide customers through supplier engagement campaigns — helping them mobilise their supply chains to collect emissions and decarbonisation data on the Green Project platform
• Build strong relationships with sustainability, procurement, and ESG stakeholders at customer organisations
• Conduct regular business reviews to track programme performance, surface insights, and identify growth opportunities
• Act as the regional voice of the customer internally, feeding back product and process improvements to the wider team
• Support commercial outcomes by identifying upsell opportunities and managing your customers' renewals
• Contribute to localising CS playbooks, templates, and communications for the Japanese and broader APAC market

• 3–6 years of experience in Customer Success, Account Management, or a client-facing role in a SaaS environment
• Native or business-level Japanese; business-level English (written and spoken)
• Genuine interest in sustainability, ESG, or supply chain — you don't need to be a carbon accounting expert, but you should care about the mission
• Strong relationship-building skills and cultural fluency in Japanese business contexts (keigo, stakeholder hierarchy, consensus-based decision-making)
• Comfortable managing multiple accounts and complex, multi-stakeholder programmes simultaneously
• Experience working with CRM tools; HubSpot experience is a plus
• Collaborative and comfortable working across time zones with distributed global teams

Nice to Have

• Japanese language skills (spoken and/or written)
• Experience at a foreign-owned or international company operating in Japan
• Background in sustainability, climate tech, or supply chain management
• Familiarity with Scope 3, GHG reporting frameworks (GHG Protocol, CDP, CSRD), or supplier engagement programmes
