From 2008 to 2013, we published sustainability reports based on the Global Reporting Initiative reporting standards. Our 2020 ESG report marks the latest step in reporting publicly on our sustainability governance journey.
Over the past several years, the board has overseen a substantial increase in the volume and depth of sustainability disclosure, including the discussion of our environment and climate change strategies in the Annual Information Form, and the descriptions of our risk management practices in the
Management's Discussion and Analysis, and the physical and transition risks from weather and climate change.
In 2020, the board and management embarked on the development of expanded ESG reporting. The Environmental, Health & Safety Committee, Corporate Governance & Nominating Committee, and Human Resources & Compensation Committee each led reviews of performance metrics and reporting standards in their areas of oversight. The board oversaw management's work on the report's development, and the Audit Committee oversaw the disclosure process.
Our 2020 ESG Report reflects the work of the board and management and was shaped by feedback from stakeholders representing a diverse range of interests and experiences. The feedback from the materiality assessment resulted in the qualitative and quantitative information in the report being structured around 10 ESG factors most relevant to stakeholders and the company.
Through our reporting on those factors, stakeholders from all backgrounds can discover information of relevance to them that speaks to the company's impacts, and to how we are managing the risks and opportunities that ESG presents.
