{"slug":"bosques-sostenibles","name":"Bosques Sostenibles","tagline":"Cantabrian company planting corporate CO2-offset forests on burnt and degraded public land in Spain and Portugal","description":"Bosques Sostenibles SL is a Santander-based company that designs, plants and maintains \"corporate forests\" for companies and individuals wanting to offset CO2 emissions. It typically works on fire-damaged or degraded public forest land (montes de utilidad pública) under agreements with regional governments and municipalities, which cede the CO2 fixation rights for 40 years in exchange for free reforestation; projects include the Valle de Iruelas and Navalacruz in Ávila (burnt in 2019 and 2021), Mijares, Las Rozas (Madrid), Viu de Llevata (Lleida) and Soraluze (Gipuzkoa). Its website reports more than 52 projects since 2011, 1,350,000 trees planted, 940 hectares repopulated, 240,000 tCO2 and 18,800 days of local employment, with about 300 companies and 95 individuals as offset clients. It says it is working toward B Corp certification; it publishes no annual report.","website_url":"https://www.bosquessostenibles.com","logo_url":null,"founded_year":2011,"org_type":"company","scope":"national","headquarters":{"city":"Santander","region":"Cantabria","country":"ES","lat":43.4623,"lng":-3.81},"volunteer_url":null,"donation_url":"https://www.bosquessostenibles.com/particulares-comprar-arboles/","events_url":null,"featured":false,"trees_on_record":1350000,"primary_activity":"carbon-offset-planting","activities":[{"slug":"carbon-offset-planting","name":"Carbon offset planting","primary":true},{"slug":"reforestation","name":"Reforestation","primary":false},{"slug":"disaster-fire-recovery","name":"Disaster & fire recovery","primary":false}],"updated_at":"2026-11-08T00:02:16.194Z","url":"https://treerm.org/org/bosques-sostenibles","markdown_url":"https://treerm.org/org/bosques-sostenibles.md","api_url":"https://treerm.org/api/v1/organizations/bosques-sostenibles","data_note":"Bosques Sostenibles publishes no annual report, so only cumulative snapshots exist: more than 290,000 trees and 190 ha in December 2017 (press), nearly 500,000 trees and 201 ha in January 2024 (founder interview), and 1,350,000 trees and 940 ha on its website in November 2026.
