If the current rate of plastic production continues, it could use up the global carbon budget to limit global warming to 1.5 degrees Celsius by as early as 2060 or no later than 2083, according to a new study. The study by the United States' Lawrence Berkeley National Laboratory (LBNL) comes ahead of the fourth round of United Nations negotiations for an international treaty to end plastic pollution in Ottawa, Canada, during April 23–29. It is estimated that global plastic production today accounts for around 12 per cent of total demand for oil and 8.5 per cent of total demand for natural gas.
