Short-Lived Climate Pollutants

 

Reducing Short-Lived Climate Pollutants

The International Solid Waste Association – ISWA, published a comprehensive report completed by SCS Engineers for ISWA under the Climate and Clean Air – CCAC, on reducing Short-Lived Climate Pollutants. A CCAC Solid Waste Emissions Estimation Tool – called SWEET, was used to investigate waste sector emissions of short-lived climate pollutants -termed SLCPs, and other greenhouse gases – GHGs.

Data was collected where multiple waste management scenarios in Tyre Caza, Lebanon. Publications on waste management in Lebanon, including an Integrated Waste Management Plan and Updated Master Plan for the closure and rehabilitation of uncontrolled dumpsites throughout Lebanon, provided data that were used in this study along with updated information provided by Lebanon’s Office of the Minister of State for Administrative Reform.

Different management options for reducing emissions of SLCPs over the short- and medium-term. Comparing emissions reductions achieved by implementing a range of programs over a meaningful time horizon provide greater clarity of vision to see which strategies produce the most climate benefits and are worth a high level of effort and the commitment of resources to achieve.

Solid Waste Emissions Estimation Tool

SWEET is designed to be used by solid waste planning professionals worldwide. It allows some degree of flexibility in selecting key inputs, which gives it greater control and ability to reflect local conditions but adds a level of complexity that may be difficult for some users to navigate. While offering users control of some model assumptions, SWEET includes many calculations and assumptions that are necessarily fixed and can produce unintended results given the model’s limitations. In addition, the assignment of input data that appropriately reflects actual and expected conditions can be challenging, especially when there is a large amount of information to be considered.

The reports on solid waste management in Lebanon and Tyre Caza following the waste management crisis provided multiple sources of data that required evaluation and processing before being used in SWEET.

Training

ISWA and CCAC will be sponsoring a training workshop on the use of SWEET in the future. For advice and guidance using SWEET contact Alex Stege, SCS Engineers Senior Project Advisor, and Expert on Landfill Gas Modeling.
