|| Experts estimate that 8 to 12 % of greenhouse gas (GHG) emissions in developing and threshold countries are due to waste management activities. The major sources are methane emissions from disposal of untreated municipal solid waste, which in those countries contains a large portion of degradable organics. The Clean Development Mechanism (CDM) offers the opportunity to get emission reductions certified and to make them sellable. However, the CDM methodologies do not generally promote enhanced technologies in waste management. The financial contribution from carbon trade to the enhanced climate mitigating technologies like MBT and combustion does not crack the invest barriers nor recover the higher operation costs. Most recent activities target on improving existing CDM methodologies and on developing new concepts.
