The Basel Convention has estimated the amount of hazardous and other waste generated for 2000 and 2001 at 318 and 338 millions tonnes respectively. However these figures are based on reports from only a third of the countries that are currently members of the Convention (approximately 45 out of 162). Compare this with the almost 4 billion tonnes estimated by the Organisation for Economic Co-operation and Development as generated by their 25 member countries in 2001 (Environmental Outlook, OECD) and the problems of calculating a definitive number for global waste generation are obvious.
