The speech, delivered as part of an event by the Inter-American Development Bank [IDB], reaffirmed the U.S. commitment to the IDB's Amazonia Forever program on its first anniversary, a project intended to promote sustainable development in the Amazon region and defend against deforestation.

Remarks by Secretary of the Treasury Janet L. Yellen at the Goeldi Museum in Belém, Brazil
Inflation Reduction Act "Net-Zero Principles for Financing and Investment to provide guidance to U.S. financial institutions pursuing net-zero commitments"
I. Strengthening Relationships with our Allies and Partners
II. Making the International Financial Architecture Work Better for Countries
III. Harnessing the Power of Markets
"Ultimately, through strengthening relationships, making the international financial architecture work better for countries, and harnessing the power of markets, we're making progress toward tackling climate change, the loss of nature and biodiversity, and related challenges"

Yellen urged coordination between the U.S. and countries like Brazil, Colombia, and Ecuador to achieve global climate and economic goals—working within and across countries to catalyze investment in agriculture and infrastructure projects.

"Globally, nature crimes are estimated to generate proceeds in the hundreds of billions of dollars annually and often entail misusing and abusing the U.S. financial system. Given the importance of the U.S. dollar and financial system to international trade and finance, nature crimes present a unique money-laundering threat with respect to proceeds transiting the U.S. financial system."

Earlier Saturday, at a roundtable with IDB President Ilan Goldfajn and finance ministers in Belém, the Treasury secretary unveiled the Amazon Region Initiative Against Illicit Finance [17.07.24], a program that aims to obstruct the financing of so-called nature crimes, such as illegal logging and mining that threaten biodiversity in the region.
