    Sammanfattning : Fuel combustion for transport was responsible for 24% of EU-28 greenhouse gas (GHG) emissions in 2016. Member states are expected to ensure that the share of renewable energy in the transport sector is at least 14% by 2030. Some countries, such as Sweden, have more ambitious targets. LÄS MER

  7. 5. Values Behind Welfare Technology and Their Possible Realization : Creation of a Technology Evaluation Method for Care Practices

    Författare :Annika Hasselblad; Leif Olsson; Katarina L Gidlund; Aron Larsson; Xiu Gu; Mittuniversitetet; []
    Nyckelord :Care; evaluation; technology; values; welfare technologies.;

    Sammanfattning : In 2018 the Swedish government approved a SEK 350 million grant to increase the municipal implementation and use of welfare technologies in areas such as health care, care, and social service. Welfare technologies have been criticized for their effects on care workers’ work environment, such as increased stress due to time and performance demands. LÄS MER
