Carine Barbier, Household Preferences for Reducing Greenhouse Gas Emissions in Four European High Income Countries.

The basic idea of the HOPE project is to analyze household response to a more stringent climate policy regime on reducing household greenhouse gas (GHG) emission in the range of 50% by 2050, and from this analysis suggest possible changes in current climate policy regimes at EU, national and local levels. The project addresses three areas : the drivers behind current household emission, household choices to achieve GHG reduction targets, economic and health costs and benefits of each choice. Household surveys in four European cities have been conducted to investigate, how private households can make climate friendly decisions in their daily routine to facilitate reaching the climate targets implemented by the European Union. Aix-en-Provence (France), Bergen (Norway), Mannheim (Germany) and Umea (Sweden) has been investigated. In our interview survey and simulation, households have been offered 60 possible choices in order to comply with the long-term goal of reducing their GHG emissions by 50 % within 2050 ; ranging from nutritional options, mobility lifestyle changes to climate-friendly in-vestments in their homes. In addition to the potential of a given choice to reduce emissions, interviewees have immediately been informed about the costs and savings as well as possible health co-benefits accruing to them through each of their choices. The four study countries offer different contexts in climate policy, GHG-emission profiles and energy supply. The study comprises three stages : 1. A household interview survey including the assessment of the current household foot-print of direct and indirect GHG emissions. 2. An on-site simulation, in which the researchers will run the household through a GHG reduction simulation program of 60 GHG saving measures. 3. A semi-structured qualitative follow-up interview addressing household views on potential barriers and motivation for the measures chosen in stage 2. The project will end on October 2017. We have at this stage only preliminary results.
