This report brings together multiple lines of evidence derived from a wide range of sources. It draws upon targets, commitments and activities of countries as reported in national biodiversity Strategies and action plans (NBSAPS) and national reports, as well as Parties’ own assessments of progress towards the Aichi biodiversity Targets. It takes into account information on the status and trends of biodiversity reported by Parties and in the scientific literature, and makes use of indicator based statistical extrapolations to 2020 as well as longer term model based scenarios.

El GEO 2014 está estructurado de manera similar a los informes anteriores, manteniendo el marco metodológico propuesto por PNUMA, cuyo núcleo central es el análisis del estado-presión-respuesta del medio ambiente y los recursos naturales. Dos elementos complementan el marco metodológico mencionado: las fuerzas motrices como causas estructurales de los cambios generados y los impactos que recaen sobre el medio ambiente.
