Carbon Offsetting
As part of ATBC’s ongoing commitment to sustainability and climate responsibility, ATBC2025 is proud to support the Comité de Recursos Naturales de la Chinantla Alta (CORENCHI) as this year’s official carbon mitigation project.
CORENCHI is a community-led conservation initiative located in the Sierra Norte region of Oaxaca, Mexico. Through a model of voluntary conservation agreements and strong local governance, the CORENCHI communities collectively protect more than 34,000 hectares of forest, safeguarding biodiversity and contributing to climate mitigation efforts.
We invite all delegates to contribute to this important initiative. Suggested donation amounts are based income classification of your country of residence:
-
$25 USD – High-income countries
-
$17 USD – Upper middle-income countries
-
$13 USD – Lower middle-income countries
-
$7 USD – Low-income countries & host country (Mexico)
Your contribution will directly support the ongoing conservation efforts of CORENCHI and help offset the carbon footprint associated with ATBC2025.
Comité de Recursos Naturales de la Chinantla Alta
The Comité de Recursos Naturales de la Chinantla Alta (CORENCHI) was established in 2004 by the communities of Santa Cruz Tepetotutla, San Antonio del Barrio, San Antonio Analco, Nopalera del Rosario, and San Pedro Tlatepusco through a regional agreement in which they recognized that water, air, seeds, and, more broadly, biodiversity do not follow territorial boundaries. Therefore, they committed to their conservation and sustainable use.
The CORENCHI communities have certified 81% of their territory as Voluntarily Designated Conservation Areas (Áreas Destinadas Voluntariamente a la Conservación, ADVC) with CONANP (National Commission of Natural Protected Areas) and have developed territorial strategies for the management of their forests and productive zones through land-use planning, customary normative systems, and forest management strategies—including a guide of best management practices.
These community-based territorial strategies have enabled a cloud forest—highly vulnerable to climate change and with a high accumulation of combustible material (such as leaf litter up to one meter deep, which can turn into dry peat)—to remain free of wildfires for over 24 years.
The CORENCHI communities span an area of 34,000 hectares, where a total of 1,788 species of flora and fauna have been recorded to date. Of these, 567 species have been identified through monitoring conducted by local technicians. The recorded species include 42 amphibians, 32 reptiles, 143 birds, 40 mammals, 250 butterflies, and 60 orchids (Source: CORENCHI, 2020).
Through biodiversity monitoring led by community technicians, 94 species have been recorded in some category of risk according to the Mexican Official Standard NOM-059 and the IUCN Red List. Among these, 22 are classified as Threatened (A), 13 as Endangered (P), and 61 are endemic to Mexico—including 18 species found exclusively in the state of Oaxaca.
The CORENCHI territory is home to all six feline species present in Mexico: jaguar, puma, jaguarundi, margay, bobcat, and ocelot.
Productive activities in the region are biodiversity-friendly, with coffee and cacao cultivation, beekeeping, stingless beekeeping (meliponiculture), and traditional milpa agriculture standing out. Additionally, initiatives have been launched to conserve agrobiodiversity and to implement climate change adaptation strategies within productive systems, using bio-inputs, pollinators, and cultural practices aimed at achieving food self-sufficiency and accessing differentiated markets for their products.
