The archived site at this address carried sign-on pages: statements that invited organisations to attach their names, and that grew longer with every name attached. The mechanism is so familiar in movement politics that it is rarely examined. The sheet examines it here, because the signature is one of the oldest organising instruments the climate movement inherited.

What a signature does

A signature on a movement statement does three things at once. It associates the signer with the argument; it adds the signer's constituency to the statement's readership; and it makes the document cumulative, a text that grows after publication. The sign-on page is therefore not an appendix to the statement. It is the statement's second half, written by its readers.

The list as evidence

The signature list is the statement's evidence of weight. A declaration signed by two hundred organisations speaks differently than the same text signed by twenty, and the names themselves carry information: which continents, which kinds of organisation, which movements lent their credibility. Reading a signature list is reading the coalition that produced it.

What the signature is not

A signature is not membership, not endorsement of everything the signer ever does, and not a contract. It is a public act of association with a text at a moment. The sign-on mechanism works precisely because the commitment is bounded: cheap enough to gather widely, public enough to mean something. The sheet notes this because readers of archived sign-on pages sometimes mistake the list for a living roster. It is a record of who signed then, not who stands where now.

The work after the signature

The real organising begins after the name is attached. A sign-on list is a contact list in disguise: every organisation that signed is an organisation that can be written to, mobilised again, asked to translate or host or testify. The statement is the first task the list performs together, not the last. Coalitions are measured by what their signature lists go on to do, and the strong ones treat the list as a working instrument, not a trophy page.

This is also why the mechanism persists despite its weaknesses. A petition page costs almost nothing to publish and produces, in the best case, a durable map of willing partners. The archived sign-on pages at this address show the instrument in its working state: a statement, a form, and a list that kept growing because somebody maintained the network behind it.

The mechanism's limits

The sign-on also has known weaknesses: verification is light, names accumulate without scrutiny, and the list can outlive the consensus it records. An archived signature page preserves the list at its height and preserves nothing of what the signers thought five years later. The mechanism's strength, accumulation, is also its archival danger.

The signature in the archive

On the site that lived here, the sign-on pages are among the most instructive captures: they show the coalition at work converting agreement into numbers, and they show the archive doing what it does best, preserving the instrument rather than the outcome. The declaration desk keeps them as specimens of a form.

A signature page, read carefully, is a record of who could be convened at a moment in history. The list is the coalition's own archive of its reach, filed under the text that produced it.
