  4. 2. Studies of Tropospheric and Stratospheric Aerosol using Ion Beam Analysis

    Author : Giorgos Papaspiropoulos; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atmosphere; Aerosols; troposphere; stratosphere; ion beam analysis; PIXE; impactors; particulate sulphur; chemical speciation; elemental analysis; thermography; Physics; Nuclear physics; Fysik; Metrology; Kärnfysik; physical instrumentation; Metrologi; fysisk instrumentering; Fysicumarkivet A:2001:Papaspiropoulos;

    Abstract : Atmospheric aerosol particles are believed to have an impact on the radiative forcing of the earth's surface. The predicted results indicate a net cooling effect on the global climate, however there are few studies available to substantiate this and experimental data are needed. READ MORE

  5. 3. Income, Energy Taxation, and the Environment : An Econometric analysis

    Author : Tarek Ghalwash; Runar Brännlund; Pere Riera; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Household consumption; energy demand; emissions; rebound effect; energy taxation; tax elasticities Environmental services; income elasticities; Engel Curves; income distribution.; Economics; Nationalekonomi;

    Abstract : This thesis consists of four papers: two of them deal with the relationship between consumption, energy taxation, and emissions on macro level, and two of them focuses on the effects of changes in consumption and income on the environmental quality on a micro level. The main objective of paper [I] is to examine how exogenous technological progress, in terms of an increase in energy efficiency, affects consumption choice by Swedish households and thereby emissions of carbon dioxide (CO2), sulphur dioxide (SO2) and nitrogen oxide (NOx).
