This report concerns the publication and citation performance of researchers within seven research programs financed by the Swedish Environmental Protection Agency (SEPA). Papers published by 118 researchers are compared with papers published by their international colleagues during the same time period, i.e. 2002–2007. Results indicate that the citation impact is significantly above international reference levels: SEPA programs receive 31% higher citation scores in their journals; this translates to a field-normalized impact of 66% above world average. This can be explained by the fact that researchers financed by the SEPA publish in journals with high impact-levels – 34% above the global reference value (see Table 3, page 9). Papers from SEPA financed programs occur about 140% more often than expected among the top 5% most frequently cited papers in their subfields. This finding shows there is an extensive core of highly cited papers. The overall quality of the publications funded by the programs is impressive.Seen from an international perspective the citation impact of the Swedish National Air Pollution and Health Effects Program (SNAP) is considered as Outstanding. Three programs are considered as Excellent and internationally competitive – Aquatic Aliens, Communication, Organisation, Policy Instruments, Efficiency (COPE) and Naturvårdskedjan. One program, Marine Biodiversity, Patterns and Processes (MARBIPP), is graded as Very Good.Reproduction and Chemical Safety (REPROSAFE) has an impact considered as Good, that is, at international average. Achieving Greater Environmental Efficiency (AGREE), with few papers, has an impact considered as Insufficient.The above estimated performance figures are based on all program-related papers by researchers from the SEPA-programs. Such a precise delineation of results related to the SEPA-initiative has to rely on researchers self-reporting. About 200 articles out of 1000 authored by the researchers were validated as produced based on the SEPA funding of programs. It should be noted that the bibliometric methods applied in this report might not be suitable for all programs due to their different publication practices. To meet the methodological challenges posed by social science publication strategies there is a separate report where the COPE-program is evaluated with an expanded mix of bibliometric methods.The SEPA programs have a productivity performance per researcher which is at the expected level for a normal Nordic researcher in these areas of research. As the impact of the programs is fairly high measured as field normalized citations the conclusion is that SEPA has funded high impact research yielding evidence of productivity and international competiveness.
