What it is
What STANAG 2594 covers
STANAG 2594 is the NATO standardization agreement that gives force to AJEPP-7, Edition B, the Allied publication on best environmental protection practices for sustainability of military training areas. A STANAG is not itself a technical specification: it is the agreement by which NATO nations commit to implement one, and the actual practices sit in the Allied Publication it covers. This STANAG responds to an interoperability requirement stated plainly in the document: "to employ voluntary best environmental protection practices for sustainment of military training areas, contributing to the ability of Alliance forces to train, exercise and operate effectively, both together and with forces of Partner and other non-NATO countries." The cover adds that "most Alliance nations share common supranational environmental legislation, which mandate national and NATO authorities to proactively develop, agree and implement concepts, practices and procedures" for training areas, which is the reason the agreement exists rather than a requirement of its own.
This is Edition 2, promulgated 7 January 2020. It "supersedes the following document: STANAG 2594, Edition 1, dated 31 March 2014."
Who ratifies it, and how it takes effect
The mechanism that matters here: a STANAG binds a nation, not a supplier. Nations "are invited to examine their ratification of the STANAG and, if they have not already done so, advise the NSO of their intention regarding its ratification and implementation," and the national response is recorded in the NATO Standardization Document Database (NSDD). Once ratified, the agreement "is effective upon receipt for use by the participating nations and NATO bodies," and "participating nations agree to implement AJEPP-7, Edition B, in accordance with their ratification responses." Partner nations are separately "invited to provide their implementation details through the electronic reporting tool," rather than required to. A supplier or a range-support contractor meets AJEPP-7 only where a contract or a tender brings it in by name, not because this STANAG exists on its own.
Related documents named on the cover
Alongside AJEPP-7, the cover names four related documents without describing what any of them requires: MC 0469/1 (NATO Military Principles and Policies for Environmental Protection), STANAG 7141 (AJEPP-4, joint NATO doctrine for environmental protection during NATO-led military activities), STANAG 2582 (AJEPP-2, environmental protection best practices and standards for military camps in NATO operations), and STANAG 2583 (AJEPP-3, environmental management system in NATO military activities). The cover is silent on what any of these three STANAGs or MC 0469/1 actually contain; only their titles appear here.
How it's evaluated
The cover names no certification, no accredited body and no notified body. What it describes is a national ratification, implementation and review cycle run through NATO's own machinery: nations record their ratification and implementation details in the NSDD, and "this STANAG is to be reviewed in accordance with AAP-03. The result of the review is recorded within the NSDD." (AAP-03 is the directive that governs how a STANAG review runs.) There is no audit against this cover as such; the substance an organisation would actually be checked against, where a contract required it, is AJEPP-7 itself, which this cover does not describe.
