22 Nov 2021 --- The US government is supporting calls for a global treaty to curb plastic pollution. Secretary of State Antony Blinken made the announcement at a recent UN climate summit in Kenya, marking a U-turn on the Trump administration’s stance. Blinken says the treaty, which will be discussed at an international meeting in Nairobi, Kenya, next year, must “call on countries to develop and enforce strong national action plans to address this [plastic pollution] problem at its source.”
