1 Scope

This PAS specifies requirements for calculating and indexing CO₂ emissions for earth-moving machinery operating in civil engineering construction sites conducting five types of work:

1. hauling with dumper;

2. excavation with excavator;

3. loading with excavator;

4. backfilling with excavator; and

5. compacting/ground levelling with dozer or roller.

This PAS covers:

1. defining the worksite;

2. data identification and collection;

3. the calculation of CO₂ emissions for individual machines;

4. the calculation of CO₂ emissions by machine and work type;

5. the calculation for indexing CO₂ emissions by machine and work type; and

6. worksite factors that impact CO₂ emissions and calculation for compensation.

This PAS is for use by those construction companies, manufacturing or operating earth-moving machinery, research organizations, trade associations and government agencies. It might also be of use to carbon assessors.

This PAS does not:

1. cover other types of construction equipment (e.g. lifting or tunnelling machinery);

2. cover the calculation of the total amount of greenhouse gas (GHG) emissions for the entire construction site;

3. cover earth moving machinery (EMM) cycle patterns (e.g. 90° loading or 180° loading) or cycle speeds;

4. provide machine operating instructions or describe how to report on CO₂ emissions; or

5. include CO₂ emissions for the full life cycle of the machinery (e.g. from production to end of life).
