The lexicon was developed by the Forest Carbon, Markets and Communities (FCMC) Program and Tetra Tech ARD for the United States Agency for International Development (USAID)

USAID is leading the United States Government’s implementation of its Strategic Choices for United States Fast Start Financing for REDD+. To pursue this strategy efficiently requires effective communication between government agencies and public and private sector institutions based on mutual understanding of vocabulary, acronyms, definitions, and vocabulary categories.

The role of this Finance and Carbon Markets Lexicon is to provide a tool that encourages effective communication between government agencies and public and private sector institutions. To do this, this lexicon contains a list of relevant vocabulary, definitions, reference sources, and acronyms organized around vocabulary categories as applied by the public- and private-sector REDD+ industry globally.

The categories around which the lexicon is organized provide a framework for understanding the relevance of each term to finance and carbon markets. The vocabulary categories are broken into two broader themes of financial vocabulary and carbon accounting vocabulary. There are four financial vocabulary categories that are based on international finance best practices. These categories are: There are seven agriculture, forestry and land-use categories based on carbon accounting international best practices. These categories are:

    Carbon dioxide (CO2) emissions generated from operations (server, data transfer, travel) are mitigated through an association with Anthrotect,
    an organization working with Afro-indigenous and Embera communities to protect forests in Colombia's Darien region.
    Anthrotect is protecting the habitat of mongabay's mascot: the scale-crested pygmy tyrant.

    "Rainforest" is used interchangeably with "rain forest" on this site. "Jungle" is generally not used.
