The Australian Greenhouse Office indicated that waste emissions contributed 3.1% of net national emissions in 2001 with methane emissions from landfills accounting for 92% of total methane emissions from the waste sector, despite an increase in methane recovered from solid waste. It pointed out that the recent changes in waste management practices did not have an impact on reported methane emission levels and there is need to undertake a range of activities to reduce emissions from waste management activities. This project will address specifically the above issue by providing a new method of analysis to predict gas leakage rate and allow engineers to propose solutions to mitigate gas escapes.

澳大利亚温室气体办公室指出，2001年，废物排放占全国净排放量的3.1%，尽管从固体废物中回收的甲烷有所增加，但填埋场的甲烷排放占废物部门甲烷总排放量的92%。它指出，最近废物管理做法的变化没有对报告的甲烷排放水平产生影响，需要开展一系列活动减少废物管理活动的排放。该项目将通过提供一种新的分析方法来预测气体泄漏率，并允许工程师提出减少气体泄漏的解决方案，从而专门解决上述问题。
