We aim to align our reporting with what we believe to be the best standards for non‑financial reporting. We believe in reporting against reliable data and strive to improve the quality of our non‑financial disclosures.
Towards these aims, we engaged KPMG again this year to provide limited assurance of three aspects of our report, determined as being highly material to the success of our Sustainability & Responsibility Strategy:
- Our application of the Global Reporting Initiative (GRI) principles of ‘materiality’ and ‘stakeholder inclusiveness’ during the evolution of our Sustainability & Responsibility Strategy
- Reliability of environmental performance data for 2013 (carbon emissions, water usage, biochemical oxygen demand (BOD), and waste to landfill)
- Our self-declared GRI application level.
As in previous years, we also engaged the London Benchmarking Group to assure our community investment data and methodology.
