Text: the authors confirm that, for approved reasons, some access restrictions apply to the data underlying the findings. we stated that our data are available upon request. this is due to legal reasons as we obtained our data from a third party. to estimate age profiles of carbon emissions we used data from the consumer expenditure survey (available at http://www.bls.gov/cex/) and economic input-output life cycle assessment tables (available at www.eiolca.net). the estimates of labor force participation by age, sex and highest level of educational attainment in 2008 in germany and in sweden are based on data from eurostat, eu labour force survey. the responsibility for all conclusions drawn from the data lies entirely with the authors. the data are available upon request from estat-microdata-access@ec.europa.eu. data on assumptions and results for the education-specific population projections for germany, 2008 to 2053, can be obtained from elke loichinger, iiasa (loiching@iiasa.ac.at). to estimate healthy life expectancy shares we use data from the german socio economic panel from the diw (german institute for economic research). the data is available upon request from michaela engelmann (soepmail@diw.de). in addition, life expectancy estimates from the human mortality database are used. the data can be obtained free of charge at www.mortality.org. for the last part, we use data from the income and expenditure survey 2003. the data can be obtained from the german federal statistical office, service wirtschaftsrechnungen und zeitbudget (viiid-info@destatis.de). in addition, the non-monetary results are estimated using the time use survey 2001/02. the data are available upon request from the auskunftsdienst einkommen, konsum, lebensbedingungen of the federal statistical office (forschungsdatenzentrum@destatis.de). national transfer account data can be obtained from fanny a. kluge, max planck institute for demographic research (kluge@demogr.mpg.de).<|eot_id|><|start_header_id|>assistant<|end_header_id|>
