Elements and Performance Criteria

1. Identify all sources and uses of materials in process
   • Identify all sources of materials external to the site.
   • Identify all sources of materials within the site, where appropriate.
   • Identify all uses of materials by the process overall.
   • Identify all uses of materials by each process unit.
2. Calculate theoretical use of the materials
   • Calculate theoretical net consumption of material for each process unit.
   • Calculate overall material balance for process/site.
   • Evaluate the need for material consumption by process and units within the process compared to alternative processes/units.
3. Measure actual use of materials
   • Determine actual net material consumption for overall process/site.
   • Determine actual net material consumption for each process unit.
   • Calculate difference between theoretical and actual material consumption by unit and overall.
   • Identify actual emissions by each process unit.
4. Develop strategies for reducing emissions
   • Rank units by difference between theoretical and actual material consumption.
   • Rank units by actual material consumption.
   • Develop strategies to reduce material consumption.
5. Prepare a recommendation for an emissions reduction strategy
   • Consult with key stakeholders.
   • Identify strategies required to meet regulatory or similar requirements.
   • Rank strategies by benefit/cost ratio.
   • Short-list preferred emission reduction strategies.
   • Prepare recommendation for reducing emissions.

Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.
Materials include one or more of	materials directly used and also materials which comprise components which are used materials/resources which may be consumed to make a physical product materials which may be consumed in delivering a service (e.g. fuel, energy and other consumables).
Emissions include one or more of	fluid leaving the process, other than as part of the product solid leaving the process, other than as part of the product material leaving in waste streams or entering the process but not leaving as part of the product.

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include the ability, for one or more products/processes or part/all of the value chain, to:

define appropriate boundaries for the sustainability emissions audit

conduct material balance analyses for a site or value chain

identify high emissions units/areas

undertake benefit/cost ratio analyses

ensure improvement strategies proposed reflect stakeholder needs and regulatory environment.

---

Knowledge Evidence

Must provide evidence that demonstrates sufficient knowledge to interact with relevant personnel and be able to conduct an audit of emissions including knowledge of:

nature of emissions

material balancing techniques for process and process steps (sometimes known as mass balancing)

methods of measuring actual process amount/flows

emission reduction strategies and methods along with costs, effectiveness and alternative disposal strategies caused

cost-benefit analysis

relevant legislation, regulations and protocols.
