Drawing on the clause 4 principles, the risk and opportunity process, systems thinking and the constructive challenge approach, and looking across temporary activities, the life cycle of each product or service, geography, assets and their lifetimes, ownership and finance and the supply chain, the organisation works through four stages for the environment. First it identifies environmental risks and opportunities, sorting them into categories, learning what interested parties need and fear, settling where environmental materiality lies, establishing its tolerance and vulnerabilities, and keeping a record of evidence, reasoning and results. Second it evaluates and assesses impacts, putting in place approaches and action plans that are accurate, trustworthy and grounded in science and evidence, using environmental assessment tools where needed to establish materiality, significance, magnitude and likelihood, choosing the material areas to prioritise from what has been observed or found, running evidence and data systems that are open about uncertainty, assumptions, methods and metrics, and tracing the dependencies that link environmental factors with social and governance ones. Third it sets the outcomes it wants and how it will get there: a justified baseline aiming at stretch targets, benchmarks for success, targets and metrics for the near, middle and long term with critical success factors, analytical tools to measure and monitor iteratively, and a record of what was achieved and which barriers were overcome. Fourth it reports, discloses and communicates, framing outcomes as claims that can be assessed, verified or validated by interpretable and repeatable means, giving access to the reports and the evidence and methods behind them, and correcting errors, omissions and misstatements quickly and telling all interested parties. Life cycle assessment, environmental impact assessment, water, carbon and ecological footprints, air emission studies, energy and material balances and biodiversity net gain are among the tools that help with identification; an action plan built on the outcome-focused, evidence-based and sustainable principles structures delivery, and the IWA's table of example environmental actions shows the kinds of measure available.
