The eight countries that share the Amazon basin have fallen short of an agreed goal to end deforestation.
Ednews informs via foreign media that delegates from the countries are meeting in the Brazilian city of Belém for a two-day summit on the issue.
A joint declaration on Tuesday created an alliance to combat deforestation, but left each country to pursue its own conservation goals.
Climate activists said the deal lacked concrete measures at a time "when the planet is melting".
"Temperature records are broken every day, it's not possible that under those circumstances, the eight presidents of the Amazon nations can't include a line in the declaration stating, in bold letters, that deforestation needs to be zero, that it won't be tolerated any more," Márcio Astrini of the Climate Observatory group said.
Around 60% of the Amazon, the largest rainforest in the world, lies in Brazil. The other countries represented at the gathering are Bolivia, Colombia, Ecuador, Guyana, Peru, Suriname and Venezuela.
