The growing emphasis on environmental sustainability within the European Union raises important questions about the nature and internal structure of corporate envi-ronmental effort. This study examines environmental expenditures - measured as in-termediate consumption of environmental protection services - and environmental investments - measured as gross fixed capital formation for environmental protection - in ten EU member states over the period 2015-2022, using data from the Eurostat En-vironmental Protection Expenditure Accounts. The analysis is conducted at both the national and sectoral levels and covers four NACE Rev.2 sectors: agriculture, mining, manufacturing, and electricity. The results reveal a pronounced asymmetry, with en-vironmental expenditures consistently exceeding environmental investments, sug-gesting that environmental effort is more strongly oriented towards maintenance than transformation. This asymmetry varies substantially across countries and even more across sectors: agriculture displays a strongly expenditure-dominated profile, whereas the electricity sector shows a more balanced pattern. On the basis of the relative inten-sity of expenditures and investments, the study proposes an interpretative four-quadrant typology of environmental strategies, distinguishing active transfor-mation, investment focus, maintenance mode, and passive profiles. The findings high-light the importance of sectoral disaggregation and show that the internal composition of environmental effort is as informative as its overall level.
