The Annual Report and Financial Statement (ARFS)
The primary purpose of the ARFS is to ensure compliance with legal duties and to share a range of financial and other information. To respond to the needs of our many stakeholders we provide an overview of our performance and plans, along with additional information for specialist groups and to fulfil legal requirements.
Our Contribution to Yorkshire
Our Contribution to Yorkshire is the name for our work to enhance our understanding of the impacts we have on the environment, society, and the economy.
This approach looks beyond the financial balance sheet by applying a mix of accounting, economic valuation, and sustainability techniques to assess our impacts across the six capitals, and where appropriate, put a monetary value on those impacts.
