Our Story
Green Path was established in 2013 by environmental professionals who recognized the growing need for practical, evidence-based sustainability consulting in Japan. Our founders brought together expertise in environmental science, business strategy, and regulatory compliance to create an organization that could bridge the gap between environmental ambition and business reality.
From our Tokyo office in Chiyoda-ku, we have grown to serve over 150 organizations across diverse industries. Our work spans manufacturing, technology, financial services, retail, and logistics sectors. Each client engagement has deepened our understanding of how sustainability challenges manifest differently across industries and organizational contexts.
What distinguishes our approach is the integration of rigorous scientific methodology with practical business implementation. We do not believe sustainability should come at the expense of organizational effectiveness. Instead, we help identify opportunities where environmental initiatives create business value through operational efficiency, risk mitigation, stakeholder confidence, and market positioning.
Our commitment extends beyond individual client engagements. We actively contribute to advancing sustainability practices in Japan through participation in industry associations, collaboration with academic institutions, and knowledge sharing with the broader business community. We believe that accelerating the transition to a sustainable economy requires collective action and shared learning.

Our Methodology
We employ a systematic approach to sustainability consulting that combines scientific rigor with practical implementation focus.
Evidence-Based Assessment
Every engagement begins with comprehensive data collection and analysis. We use internationally recognized frameworks and methodologies to establish baseline metrics, identify material issues, and quantify environmental impacts. Our assessments draw on peer-reviewed research, industry benchmarks, and regulatory requirements to ensure accuracy and credibility.
Stakeholder Engagement
Successful sustainability strategies require buy-in from multiple stakeholders. We facilitate structured engagement processes that gather input from leadership, employees, investors, customers, suppliers, and community members. This inclusive approach ensures strategies address genuine concerns and opportunities while building organizational commitment to implementation.
Strategic Development
We translate assessment findings into actionable strategies with clear objectives, timelines, and success metrics. Our strategic frameworks balance environmental ambition with organizational capacity, ensuring recommendations are both impactful and achievable. We prioritize initiatives based on materiality, feasibility, and potential for creating shared value.
Implementation Support
Strategy development is only the beginning. We provide ongoing support during implementation, helping organizations navigate challenges, adjust approaches based on learning, and maintain momentum. This includes developing internal capacity, establishing governance structures, creating reporting systems, and supporting change management processes.
Continuous Improvement
Sustainability is a continuous journey. We establish monitoring and evaluation systems that track progress, identify emerging issues, and enable adaptive management. Regular reviews ensure strategies remain aligned with evolving regulations, stakeholder expectations, and best practices. We help organizations build the capability to sustain and advance their environmental performance over time.
