African and South Asian nations could miss national targets to curb greenhouse gas emissions unless rich countries stop using them as dumping grounds for millions of polluting old cars, a study has warned.
The report by the Center for Science and Environment (CSE) said the United States, Japan and European Union countries had for years been exporting old, used cars — or clunkers — to nations such as Nigeria and Bangladesh.
The second-hand vehicles, which should have been scrapped under domestic regulations, are instead being used by poorer nations where they are contributing to carbon emissions, said CSE, a New Delhi-based think tank.
