Side by side

Compare organizations

Consultation participation and their own register declarations, side by side. Counts, not judgments — participation is not influence.

Counts here are a floor, never a total: they cover the 583 consultation files tracked so far (42,224 submissions, mostly 2025–26), so an organization's real filing history is larger, not smaller.

What each said, in their own words

Their opening passages on the files they share, verbatim and in filing order. We do not summarize, compare, or characterize positions — read them at source.

Batteries and waste batteries

Iberdrola S.A. · filed 8 Jul 2020 · source

Iberdrola is glad to provide feedback to this consultation sharing with the Commission and views on the critical importance of setting a forward looking framework on sustainable batteries based on their exponential growth as a driver for climate neutrality (notably in electrification of transport as shown is chart attached).

sonnen GmbH · filed 1 Mar 2021 · source

We welcome the European Union’s efforts to increase the overall sustainability of batteries. We support the level of ambition of the regulation as well as its layout, to regulate every single step in the life cycle of a battery. We understand that, in order to be as effective as possible, the regulation aims to be extensive in scope, covering a wide range of battery applications.

Iberdrola S.A. · filed 24 Aug 2026 · source
