    Sammanfattning : Transitioning the transport sector to clean energy sources is crucial for mitigating greenhouse gas emissions and achieving carbon neutrality. A collaborative solution, combining both electric vehicles and combustion engines using renewable fuels, may prove more effective than competitive ones. LÄS MER

    Sammanfattning : Deep atmospheric convection in the Indo-Pacific Warm Pool (IPWP) is a key driver of the Hadley and Walker Circulations that modulate the Asian-Australian monsoons and the El Niño Southern Oscillation (ENSO). Temperature and rainfall seasonality, i.e. LÄS MER

  4. 3. The economics of residual waste : policies, price discrimination, and welfare

    Författare :Sef Meens-Eriksson; David Granlund; Runar Brännlund; Thomas Broberg; Raymond Gradus; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Waste economics; net social cost analysis; waste incineration; municipal waste policy; waste taxes; price discrimination; spatial competition; welfare effects; Economics; nationalekonomi;

    Sammanfattning : Paper [I]: In this study, a net social cost framework is applied to provide insights on policy issues relating to the cross-border trade in waste fuel. We estimate the net social cost of using imported waste fuel in a highly efficient combined heat and power plant (CHP) in a cold climate by considering both private costs and benefits as well as external costs related to energy production, alternative waste management and fuel transport.
