According to the UNFCCC definição (abbreviation for the United Nations Framework Convention on Climate Change), the acronym REDD stands for "reducing emissions of greenhouse gases (GEE) from deforestation and forest degradation, Florestal management, maintenance and increase of carbon stock ".
In an overview, REDD part of a simple idea, where entities willing and able to reduce its GHG emissions from deforestation should be financially rewarded.
The concept was presented under the Convention on 2003, when a group of Brazilian non-governmental institutions submitted to the UNFCCC proposing a mechanism to reduce emissions offset. In 2005, a group of countries, proposed the creation of a mechanism for mitigation based on Reduced Emissions from Deforestation - RED.
With the maturing of international discussions, came the need to include forest degradation and, then, expand the approach to include countries that have forest stocks and not just those with forests under threat level, making the acronym REDD evolve.
There REDD activities in various stages of development and implementation, performed by different actors and at various locations around the world. The REDD mechanism is initiating an era of financial support for forest conservation and social development and is the object of growing international recognition.
