Our 2021 Sustainability Report


Our mission is to lead the global transition to renewable energy.Our strategy is to deliver best-in-class projects into operation, on time, on budget and safely in line with our unique Global Development Standard, and, underpinned by our values. Our aim is to achieve this in a way that embeds sustainability throughout our business approach, recognising our impacts and responsibilities, and creating value for our stakeholders, wider society and the environment in which we operate. Our new partnership with Aker Horizons will serve to fast-track these ambitions with shared values and approaches.


Our shared approach includes support of the UN Sustainable Development Goals and transparent reporting, including the principles of stakeholder engagement and materiality. In seeking greater alignment with Aker Horizons reporting approach, this report utilises the World Economic Forum’s Measuring Stakeholder Capitalism Framework: Governance, Planet, People and Prosperity. This replaces the strategic pillars of Marketplace, Workplace, Environment and Community as reported in previous sustainability reports.
