National environmental data facilities and services are part of the environmental information systems of the Ministry of the Environment of the Czech Republic that have been under development since 1990. In 2010 the development of the National Information System for Collecting and Evaluating Information on Environmental Pollution project started, co-financed by the European Regional Development Fund. This project consists of an integrated system of reporting (ISPOP), an environmental help desk (EnviHELP), and the national INSPIRE geoportal, which were developed between 2010 and 2013 and were discussed at ISESS 2013. This paper introduces the current development of several national environmental and financial data facilities and services based on eGovernment implementation in the Czech Republic and the open environmental and financial data approach of the Czech Ministry of the Environment and the Czech Ministry of Finance. It also introduces the web information system that enabled us to find the relationship between environmental economics and municipal waste management in the Czech Republic.
