Q. I need information on environmental policies of Austria, Czech Republic, Hungary, all in EU.

Try

Organization for Economic Co-Operation and Development has country profiles for environment for multiple nations.   [BEST]  

• • Locate their documents called "OECD Environment Programme" which are downloadable.
  • To get these, search "Austria AND environment" by top search bar on opening page

Alternatively, still in OECD:

• • Go in by "topic" on the ribbon
  • Expand "environment" 
  • Navigate "environment" page for data. Drawback: not easily segmented by nation.

Alternative, in OECD:

• • Select "Publications" in top navigation 
  • Select "by theme and country" and enter your choices
  • Many article hits appear in English and host nation's language

3. Europa.eu [VERY GOOD] http://europa.eu/pol/

To find documentation on environment of individual nation

• • Enter "Austria and environment" in search box on opening page
  • Hits of profiles, webpages, articles, reports about your country and topic should be arrayed in a list
  • Your country's profile should be among these hits I.e. Austria 

Alternatively, still in EU, find EU/federal level documents commenting on environment for all 28 countries.

• • Select "by topic" found on top navigation
  • Select "environment" is included in the offerings.

Drawback, this page is broad level discussion and not easily separated into individual nations http://europa.eu/pol/env/index_en.htm

 

4. European Environmental Law Homepage [GOOD] http://www.asser.nl/EEL/

• • Select "National Pages" on the top navigation 
  • Countries are displayed alphabetically, expand your selected choice (i.e. Austria)
  • Environment is kept under "Policy" section (climate, water, energy) 
  • Note: may not be in English!
