Question 1: WHEN ?Monitoring of AM0025 project
Time variables in Tool for SWDS •„Year of crediting period“ ?•„Year of project activity “ ?
www.orbeo.com 3
•„Year of project activity “ ?•„Year of calendar“ ? •„Year of waste disposal“ ?
�Project developers need flexibility(monitoring period length)

Models are:- different- but convergent to the same cumulative values
All are „First Order Decay“ models

Summary part 1: WHEN?
Currently: only yearly monitoring possible.
Suggestion: alternative models with moreflexible monitoring period length

flexible monitoring period length� further elaboration with your inputs …?
Bonus: Increase consistency in definition oftime variables („x“ and „y“)!

Leakage Emissions for decomposition residuesMust be controlled anyway… … but accounted for differently!
Thank you for your attention !And let‘s find some solutions …
