Treesy ApS

Treesy ApS er en dansk climate tech-startup, der gør det nemt, billigt og gennemskueligt for privatpersoner og virksomheder at tage konkret klimahandling gennem træplantning i Tanzania. Mange mennesker og virksomheder ønsker at gøre noget for klimaet, men oplever i dag, at løsningerne er uoverskuelige, dyre, abstrakte eller svære at stole på. Samtidig vokser både klima- og biodiversitetskrisen, og behovet for skalerbare, troværdige og handlingsorienterede løsninger er større end nogensinde. Treesy er skabt for at fjerne barriererne for klimahandling. Vi tilbyder en enkel abonnementsbaseret model, hvor kunder planter træer som en konkret måde at reducere og balancere deres klimaaftryk. Vores tilgang er baseret på konservative beregninger, radikal transparens og lokal forankring. Alle træer plantes i samarbejde med lokale partnere i Tanzania og bliver: • individuelt geo-tagget • monitoreret mindst fire gange årligt • passet og genplantet i op til tre år efter plantning Vi planter et diversificeret mix af træer med fokus på både klima, biodiversitet og lokal økonomi. Det betyder, at vores indsats ikke kun handler om CO₂, men også om at styrke økosystemer, skabe lokal indkomst og opbygge mere robuste lokalsamfund gennem agroforestry og frugttræer. Treesy adskiller sig ved at kombinere: • lav pris pr. træ • høj grad af transparens • direkte lokal tilstedeværelse • individuel geo-tagging af træer • en bevidst fravalg af dyre certificeringssystemer til fordel for direkte dokumentation Vores ambition er at gøre klimahandling tilgængelig for alle — og samtidig sikre, at indsatsen skaber reel, målbar og langsigtet impact. Treesy er stiftet af iværksættere med mange års erfaring fra udviklingsarbejde i Afrika og et stærkt lokalt netværk. Vi tror på, at ægte forandring skabes, når klima, biodiversitet og social udvikling tænkes sammen i én samlet løsning. Vores mission er enkel: At gøre det så nemt og gennemskueligt som muligt at give mere tilbage til planeten, end man tager.
