What Thinking Circular does

Thinking Circular is a German sustainability think tank and consultancy founded in 2017 by Eveline Lemke, a former Minister for Economy, Climate Protection, Energy and State Planning in Rhineland-Palatinate. The firm operates as a sole proprietorship from its headquarters at Im Schülert 13 in Niederzissen, co-located with FZ-Recycling GmbH & Co. KG at the Circular.Hotspot.de circular economy hub facility, which includes 99.9 kWp of on-site solar generation.

The company delivers four core revenue streams: tailored consulting engagements for sustainability strategy, ESRS/CSRD reporting, circular economy transformation, and climate resilience (partially funded via EU ESF Plus/BAFA programmes, capped at EUR 8,750 per SME over 2.5 years); fee-based seminars, workshops, and the Thinking Circular Academy e-learning platform hosted on Spreadmind; co-working subscriptions at the Niederzissen facility; and meeting/event room hire. Its services target German SMEs (primary), public sector organisations, large corporates requiring CSRD/CSDDD/EU Taxonomy compliance support, and circular economy start-ups.

Thinking Circular positions itself as an intermediary between science, politics, and business, with notable partnerships including the Polytechnic University of Valencia and the NATURGY Foundation, BIGL at HWR Berlin (supervisory board training from March 2025), and contributor status in REN21's Renewables Global Status Report. The firm's 'Thinking Circular®' brand is registered as an EU trademark at EUIPO. GTM is sales-led, supported by thought leadership through a bilingual website, podcast (over 120 episodes), newsletter, and an annual scientific conference at Remagen University of Applied Sciences on Ahr Valley flood recovery.
