01
Confirm residual emissions
Complete the event calculation and record reductions before determining the indicative quantity of carbon credits required.
Resource guide
Manage residual emissions as a documented sequence of project selection, purchase, allocation and retirement.

Operational guidance
01
Complete the event calculation and record reductions before determining the indicative quantity of carbon credits required.
02
Compare registry, methodology, location, vintage, project documentation and available units. Selection does not by itself complete offsetting.
03
Retain the transaction record, then allocate a defined credit quantity to the event’s residual footprint.
04
Record the retirement reference and evidence. Purchase, allocation and retirement remain separate workflow states.
05
Describe selected projects and transaction status accurately. Use documented net-zero completion only when the required retirement evidence supports it.
Working checklist
Create the event, calculate emissions, plan reductions and maintain a documented path from residual emissions to retirement.
