Environmental Charge Statistics

Access

• Index: https://www.keskkonnaamet.ee/en/supervision-environmental-charge/environmental-charge/statistics
• Fetch the index and resolve its .xlsx link against the index URL; do not hard-code the dated file path.
• Send a browser-like User-Agent and the index URL as Referer when downloading the workbook. The file host otherwise may return HTTP 403.

Retrieve

1. Parse the index for the environmental-charge statistics .xlsx link.
2. Download it with Referer set to the index URL.
3. Read both workbook sheets:
   • Maakondade kaupa: Deklaratsiooni valdkond, Maakond, Aasta, and declared-charge amount columns.
   • Liikide kaupa: the same category/year/amount fields plus whichever of Saasteaine, Maavara liik, Veekasutusala, Jäätmegrupp, or Tuulepargi liik identifies the fee subtype.

Return

Preserve the Estonian headers, workbook URL, sheet name, retrieval time, category, geography or subtype, year, and both original and rounded declared amounts.

Limits

• This is declared environmental-charge data, not payment or collection data.
• Coverage follows the current workbook; inspect its year values rather than assuming the page text is current.
• Empty subtype columns are intentional because one table combines several declaration domains.

Verify

Require an XLSX ZIP signature (PK) and the two expected sheet/header sets before using values.
