Measure the impact. Build the reduction plan.
Use two complementary tools to understand environmental performance from different angles. The Environmental Impact Calculator quantifies carbon, energy, water and waste, while the Environmental Assessment Questionnaire examines the policies, controls and practices behind those results.
Environmental performance needs a footprint you can track and a management approach you can improve.
The two tools examine the same environmental performance from different perspectives. The calculator converts operational activity into measurable indicators. The questionnaire examines whether suitable policies, responsibilities, controls and supporting evidence are in place.
Calculate environmental impact, then examine what drives it
Start with measurable indicators, then review the policies, processes and responsibilities influencing environmental performance.
Environmental Impact Calculator
Converts operational and activity data into environmental indicators that can be reviewed, compared over time and used to model improvement scenarios.
Environmental Assessment Questionnaire
Examines how effectively the organisation manages environmental responsibilities through policies, objectives, responsibilities, controls, evidence and improvement processes.
Use the right environmental tool for the right question
Both tools assess environmental performance, but they provide different types of insight and support different management decisions.
Two complementary views of environmental performance
| Dimension | Impact Calculator | Assessment Questionnaire |
|---|---|---|
| Primary output | Numerical environmental indicators and modelled reduction scenarios. | Diagnostic findings, evidence gaps and improvement priorities. |
| Input | Activity, consumption, operational and environmental performance data. | Structured responses, policies, records and supporting evidence. |
| Best suited for | Baseline creation, KPI tracking, performance comparison and scenario modelling. | Internal reviews, readiness assessments, audits and improvement planning. |
| Level of detail | Measurable footprint across carbon, energy, water and waste. | Deeper review of policies, responsibilities, controls and environmental practices. |
| Management value | Shows where impact is generated and how potential changes may affect performance. | Helps explain whether the management system can sustain environmental improvement. |
From environmental data to practical improvement
Use the tools as part of a repeatable process that measures impact, investigates management gaps and converts findings into accountable actions.
Define the boundary
Select the organisation, entity, site, activity or reporting period to be assessed.
Calculate the footprint
Enter environmental and activity data to generate measurable indicators and baselines.
Assess the management system
Review policies, responsibilities, controls, practices and supporting evidence.
Plan and monitor improvement
Model initiatives, assign actions and monitor environmental performance over time.
Measure today's impact and improve tomorrow's performance
The Environmental Impact Calculator shows where environmental impact is generated and allows reduction scenarios to be modelled. The Environmental Assessment Questionnaire examines whether suitable policies, controls and responsibilities are in place to deliver and sustain improvement.
Understand your footprint and build a practical reduction plan
Calculate environmental impact, examine the management practices behind it and convert both results into measurable improvement actions.
