About this report We referenced the Sustainability Accounting Standards Board (SASB) to identify material 昀椀nancial ESG metrics for the investor community and referenced the Global Reporting Initiative (GRI) standards to report on additional material sustainability issues. We drew upon subject matter expertise of our colleagues throughout Enphase and value chain partners to collect and organize the content relative to the areas we identi昀椀ed for disclosure. Additionally, we provided disclosures aligned with the four key themes of the Taskforce for Climate-Related Financial Disclosures (TCFD). Lastly, we compared our activities to the United Nations Sustainable Development Goals (SDGs) to assess and convey how we are contributing to these important goals.
