  3. 12. Carbon Credits: Origins, Effectiveness & Future

    Författare :Linn Takeuchi Waldegren; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additionality; carbon credits; Clean Development Mechanism CDM ; effectiveness; emissions reductions;

    Sammanfattning : Carbon credits are used as an instrument for climate change mitigation. Each credit represents a reduction in greenhouse gas emissions (GHGs) equivalent of 1 ton of carbon dioxide. LÄS MER

  4. 13. Reducing Carbon Dioxide Emissions from the EU Power and Industry Sectors - An assessment of key technologies and measures

    Författare :Johan Rootzén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industry; carbon dioxide; cement; European Union; technologies; emission reductions; CCS; power; steel; CO2< sub>; refining; mitigation;

    Sammanfattning : In February 2011, the European Council reconfirmed the goal of reducing EU greenhouse gas emissions by at least 80% by 2050, as compared to the levels in 1990. The power and industrial sectors currently account for almost half of the total GHG emissions in the EU. LÄS MER

  5. 14. Labour Market Effects of Working Time Reductions and Demographic Changes

    Författare :Oskar Nordström Skans; Magnus Wikström; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi; Economics; Nationalekonomi; nationalekonomi; Economics;

    Sammanfattning : Essay I studies the impact on actual hours worked of a 5 % working time reduction for one class of shift workers in Sweden using individual level panel data from firms’ payroll records during the sec-ond quarter each year. The main result is that actual hours only decreased by approximately 35 % of the reduction in standard hours. LÄS MER

  7. 15. Synthesis and evaluation of bicyclic 1,3-diols (BODOLs) as ligands for asymmetric catalysis

    Författare :Ian Sarvary; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organic chemistry; yeast reductions; supramolecular chemistry; diethylzinc; computation; structure of Ti-diolates; diol ligands; titanates; asymmetric catalysis; asymmetric synthesis;

    Sammanfattning : Several ligands based upon 2-substituted bicyclic[2.2.2]octane-2,6-diols (BODOLs) were synthesized and evaluated in two catalytic reactions: I) the Ti(IV)-mediated catecholborane asymmetric reduction of prochiral ketones and II) as catalysts in the asymmetric addition of diethylzinc to aromatic aldehydes.
