Chief Sustainability Officer

Job Responsibility: Role: Fractional Chief Sustainability Officer At Humiint, we recognize that sustainability is no longer just an ethical consideration but a strategic imperative for long-term business resilience, brand reputation, and competitive advantage. Integrating environmental, social, and governance (ESG) principles into core business operations is crucial for meeting stakeholder expectations, mitigating risks, and identifying new opportunities. As companies navigate increasing scrutiny and evolving regulations, they often need expert leadership to embed sustainability into their strategy and operations — without always needing a full-time, in-house executive.

This role is ideal for passionate and pragmatic leaders who are committed to driving positive environmental and social impact while creating tangible business value. This opportunity is perfect for seasoned sustainability executives who have a proven track record of developing and implementing impactful sustainability strategies, navigating complex reporting frameworks, and fostering a culture of responsible business practices. Whether you’ve been a CSO, Head of ESG, VP of Corporate Responsibility, or a sustainability consultant with executive oversight, this role offers the flexibility to apply your expertise across multiple high-impact companies. Key Responsibilities May Include:

• Developing and executing a comprehensive sustainability strategy aligned with overall business goals, industry best practices, and global sustainability frameworks (e.g., SDGs, SASB, TCFD).
• Conducting ESG materiality assessments to identify the most significant environmental, social, and governance impacts and opportunities for the business.
• Overseeing the collection, analysis, and reporting of sustainability data , including carbon footprint, resource consumption, and social impact metrics.

• Identifying and evaluating opportunities for sustainable innovation in products, services, and business models.
• Acting as an executive thought partner to founders or CEOs on all aspects of ESG strategy, corporate responsibility, and long-term value creation.

Key Requirements May Include:

• Proven experience in a senior sustainability, ESG, corporate social responsibility, or executive consulting role.
• Track record of successfully developing and implementing comprehensive sustainability strategies that drive both environmental/social impact and business value.
• Deep expertise in sustainability frameworks, ESG reporting standards, climate risk management, and circular economy principles.
• Strong analytical skills with the ability to measure and communicate the impact of sustainability initiatives.
