This chapter presents reconstructions of historical environmental accounts for Sweden for the period after 1970 with the purpose of both presenting key methodological issues pertaining to historical environmental accounting and demonstrating how historical series can be used for analysis of long-term economic and environmental change. The chapter also demonstrates how historical environmental accounts may be created by piecing together various data sources. Main empirical findings are that Swedish carbon emissions have decreased at approximately the discount rate suggested by William Nordhaus and that Environmental Protection Expenditures since 1972 have nearly been constant as a share of GDP, suggesting that environmental expenditure may have Cobb-Douglass characteristics.
