( CNN ) -- Six months after a devastating earthquake struck Haiti , most governments that promised money to help rebuild the country have not delivered any funds at all , a CNN investigation has found . Donors promised $ 5.3 billion at an aid conference in March , about two months after the earthquake -- but less than 2 percent of that money has been handed over so far to the United Nations-backed body set up to handle it . Only four countries have paid anything at all : Brazil , Norway , Estonia and Australia . The United States pledged $ 1.15 billion . It has paid nothing , with the money tied up in the congressional appropriations process . Venezuela promised even more -- $ 1.32 billion . It has also paid nothing , although it has written off some of Haiti 's debt . Former President Bill Clinton , a U.N. special envoy for Haiti , said he plans to put pressure on governments that have been slow to deliver on their promises . `` I 'm going to call all those governments and say , the ones who said they 'll give money to support the Haitian government , I want to try to get them to give the money , and I 'm trying to get the others to give me a schedule for when they 'll release it , '' Clinton told CNN 's Anderson Cooper earlier this week . He said the worldwide economic crisis was at least partly to blame . `` I think that they 're all having economic trouble , and they want to hold their money as long as possible , '' Clinton said . Altogether , about $ 506 million has been disbursed to Haiti since the donors ' conference in March , said Jehane Sedky of the U.N. Development Program . That 's about 9 percent of the money that was pledged . But about $ 200 million was money that had been in the pipeline for aid work before the earthquake , and about another $ 200 million went directly to the government of Haiti to help it get back on its feet , Sedky explained . That has left the commission with about $ 90 million in donations since the conference , Sedky said . There is some dispute about the World Bank 's contribution . The bank says it has made available $ 479 million dollars , and of that $ 56.6 million has `` already been used '' for different government-led projects . The World Bank says that this money was provided directly to the Haitian government and did not go into the Interim Haiti Recovery Commission . CNN compiled the information for this report by reviewing commission figures and surveying the donors that had made pledges to determine the disposition of those pledges . Spain , France and Canada are also among the countries that have not yet followed through on their pledges , CNN found . No countries told CNN they do not plan to deliver the money eventually . The pledges are for fiscal year 2010-2011 , so the donors have until the middle of next year to get the funds to the Haiti recovery commission , Sedky said . U.N. spokesman Farhan Haq said Wednesday that aid delivery to Haiti is going relatively well compared to other disaster relief efforts the world body has been involved in . `` Compared with other disasters , coordination systems in Haiti have actually functioned reasonably well , '' he said , adding that there was no requirement for aid efforts to work within systems . `` But within that constraint , what we 've been trying to do is coordinate the aid responses as best as we can , and we are trying to provide food as quickly as possible , '' he said . Some charities , meanwhile , are spending money as fast as they get it , while others are planning long-term projects . Doctors Without Borders -- primarily a disaster-relief organization -- has received $ 112 million and spent $ 65 million , it says . The group plans to spend more than $ 109 million by the end of the year , spokesman Michael Goldfarb told CNN . The Red Cross has spent $ 148 million of the $ 468 million it has taken in , and is holding some money in reserve for more permanent projects such as shelter and water . Private money has also come in from the Clinton Foundation , from Mexican telecommunications billionaire Carlos Slim Helu and Canadian mining investor Frank Giustra , but that 's not part of the $ 5.3 billion pledged by countries at the conference in March . The January 12 quake left more than 220,000 dead , 300,000-plus injured and more than 1 million homeless . According to recent U.N. reports , the quake destroyed 60 percent of government infrastructure and left more than 180,000 homes uninhabitable . Six months later , more than 1.5 million remain in overcrowded displacement camps . According to the United Nations , 1,300 camping sites and 11,000 latrines have been built , and thousands of kilos of food and humanitarian resources have been delivered to those in need . CNN 'S Richard Roth at the United Nations contributed to this report .
