| Summary/Abstract |
This paper provides an analysis of the current energy usage (net energy and final energy by fuels) and associated carbon dioxide (CO2) emissions of the Swedish residential building stock, which includes single-family dwellings and multi-family dwellings. Twelve energy saving measures (ESMs) are assessed using a bottom-up modeling methodology, in which the Swedish residential stock is represented by a sample of 1400 buildings (based on data from the year 2005). Application of the ESMs studied gives a maximum technical reduction potential in energy demand of 53%, corresponding to a 63% reduction in CO2 emissions. Although application of the investigated ESMs would reduce CO2 emissions, the measures that reduce electricity consumption for lighting and appliances (LA) will increase CO2 emissions, since the saved electricity production is less CO2-intensive than the fuel mix used for the increased space heating required to make up for the loss in indirect heating obtained from LA.

| Summary/Abstract |
To explore public awareness of carbon capture and storage (CCS), attitudes towards the use of CCS and the determinants of CCS acceptance in China, a study was conducted in July 2009 based on face-to-face interviews with participants across the country. The result showed that the awareness of CCS was low among the surveyed public in China, compared to other clean energy technologies. Respondents indicated a slightly supportive attitude towards the use of CCS as an alternative technology to CO2 emission reductions. The regression model revealed that in addition to CCS knowledge, respondents' understanding of the characteristics of CCS, such as the maturity of the technology, risks, capability of CO2 emission reductions, and CCS policy were all significant factors in predicting the acceptance of CCS. The findings suggest that integrating public education and communication into CCS development policy would be an effective strategy to overcome the barrier of low public acceptance.

| Summary/Abstract |
In this paper, the potential for the transportation sector to develop in a way that is consistent with long-term climate targets will be discussed. An important question is whether technical measures will be sufficient for reaching long-term climate targets. Although there is a large potential to significantly increase the use of bioenergy from today's level, there will be severe restrictions to its use within the transportation sector. Other renewable energy sources such as wind and solar are much more abundant and could provide the majority of the necessary transportation fuel in the long run. Although potentially much more expensive than current fuels they could, in combination with strong efficiency improvements, provide transport services at costs that could be acceptable in a growing economy. Transport levels as high as today or even higher could be consistent from a climate perspective if such fuels and technologies are utilised. Relying only on technical measures would, however, be risky, as there is no guarantee that the technology will develop at a sufficient rate. Furthermore, the existence of other negative environmental effects would argue for the implementation of measures affecting transport demand as well.
