A letter from our
President and CEO
I am pleased to share our 2021 Environmental, Social and Governance (ESG) report, where we discuss ongoing efforts to realise Enphase’s purpose of advancing a sustainable future for all. Since the publication of our inaugural ESG report in 2020, we have made strides in measuring our carbon footprint, cultivating a diverse and inclusive workplace, and raising awareness of ESG issues across the business. We are committed to building on this foundation to establish long-term goals aligned with the needs of global sustainable development, and I remain optimistic for what the future holds as we continue our ESG journey.

Environment
Our best-in-class energy management solutions include solar generation, home batteries, electric vehicle (EV) charging, smart load control, and cloud-based monitoring and management. While our products and services directly address the urgent challenges presented by climate change and the transition to a low-carbon economy, we appreciate that our ability to continue to do so rests in attending to, and taking accountability for, environmental impacts across the entire value chain.

People
We are building a community where everyone feels valued and treated equally at Enphase. We encourage employee well-being by offering facilities and incentives. We have laid the foundation for a robust talent management programme covering recruitment, career progression pathways and global leadership development—empowering employees, both new and existing, to reach their full potential and find satisfaction in their work.

Society
At Enphase, we take our responsibility to help expand access to clean energy seriously. We support a cleaner, more reliable and better‑performing grid, and we collaborate with a wide range of stakeholders to advance policy outcomes in support of clean energy around the world.

Governance
We regularly evaluate a myriad of risks associated with climate change, governance, human rights, integrity, employee satisfaction, finance, information technology, and other business processes to ensure a strong internal governance with clear communication. We participate in the development of policies and regulations around the world as part of our core
governance principles.

We support the United Nations Sustainable Development Goals (UN SDG) and are committed to driving progress towards achieving those goals that align with our business strategy. Learn more about our contribution to the UN SDG inside the report.

We have continued aligning ESG disclosures with prevailing reporting frameworks, including the Sustainability Accounting Standards Board (SASB), Global Reporting Initiative (GRI) and Taskforce for Climate-Related Financial Disclosures (TCFD). See the report for more information.
