At that landmark meeting, UNAIDS Executive Director Michel Sidibé called on leaders to end the epidemic by agreeing on a common agenda—an agenda that would allow us to achieve the goal of “zero new HIV infections, zero discrimination and zero AIDS-related deaths.” At the 2011 High-Level Meeting, UN member that HIV prevention and treatment could end states were also called on to reaffirm their the AIDS epidemic.3 commitment to the Declaration of Commitment Yet, just as 2011 was yielding significant new on HIV/AIDS, adopted by member states in 2001, and to make new commitments, both financially and HIV/AIDS prevention opportunities, the realities through action, to sustain the global AIDS response. of the global economic climate created constraints for global health financing in general. A scarcity The 2001 Declaration had specified a set of global of funding led to increased pressure to provide and national indicators to be monitored annually, evidence of impact and to deliver immediate value the second of which was the “amount of public for money invested.

The 2011 total investment was US$845 million, a decrease of US$14 million from 2010. As in past years, public-sector funders provided the largest part of the investment, followed by the philanthropic sector and the commercial sector.18 In 2011, the public sector provided US$702 million (83 percent), the philanthropic sector provided US$113 million (13 percent) and the commercial sector contributed US$30 million (4 percent). Investment by European governments was US$48.5 million, a decrease of over US$12 million (21 percent) from 2010, and a 40 percent decrease from the US$82 million peak in 2006.
