Its purpose is "to strengthen and coordinate the efforts of the parties to address climate change effectively in the context of sustainable economic growth, reducing greenhouse gas emissions," says the document.

The agreement also establishes a new Policy Dialogue on Climate Change between the two governments to discuss various aspects related to the topic.

Among them are the work to implement the United Nations Convention on Climate Change, and ways to build on the Copenhagen Accord "as quickly as possible."

The agreement includes strategies to reduce greenhouse gas emissions, uniting efforts for the development and dissemination of clean energy, adaptation mechanisms and scientific research.

It will also promote cooperation in increasing energy efficiency, renewable sources of energy, and reducing emissions from deforestation and forest degradation (REDD).

During the Copenhagen Conference (COP-15) last December, Brazil and the United States showed divergent positions, especially by the refusal of U.S. President Barack Obama to set more ambitious goals for fighting climate change.
