CARBON CREDITS TRADING WITH BIOLOGICAL METHANE OXIDATION AND IN-SITU STABILISATION OF LANDFILLS – PREMISES AND PERSPECTIVES

Global warming is a result of a change in the atmospheric radiative balance caused by anthropogenic emissions of so-called greenhouse gases (GHGs). Extensive research over the last two decades has resulted in a detailed understanding of the scientific background of climate change (IPCC, 1990, 1996, 2001, 2007a). Although considerable ambiguity remains on concrete measures to be taken, the scientific facts have now, at last, been accepted by practically all relevant governments and stakeholders. The urgent necessity for a drastic reduction in GHG emissions is, however, evident. According to the report on mitigation of climate change recently published by the Intergovernmental Panel on Climate Change (IPCC 2007b), a stabilisation and subsequent decrease of GHG emissions within the next 15 years will be necessary in order to limit the increase of the global mean temperature to 2 °C.

The Kyoto protocol’s project based instruments - Joint Implementation (JI) and Clean Develpoment Mechanism (CDM) - can be used to participate in carbon trading with projects aimed at the reduction of landfill gas emissions. This is already done in many projects dealing with thermal landfill gas (LFG) treatment and/or utilisation. At some point, the LFG production will decrease to a level where thermal treatment is not feasible anymore. However, the greenhouse gas emission potential of these landfills may still be significant. For these cases, innovative methods such as biological methane oxidation in landfill covers and in-situ stabilisation of landfills can be applied. However, in order to participate in carbon trading with these projects, too, sophisticated methods for both the establishment of baseline scenarios and for the evaluation of the projects’ success have to be elaborated. In a case study, the potential revenues
from carbon trading are discussed for a fictitious project for in situ stabilisation of a fictitious landfill.
