175 countries are meeting in Paris until Friday for the second of five negotiating sessions aimed at developing a legally binding treaty on plastic pollution. Saudi Arabia and several Gulf countries, producers of fossil fuels, as well as Russia, China, India and Brazil refuse that the future treaty can be approved by a two-thirds majority vote.

Until Friday, countries will work behind closed doors in two groups. The discussions will start from a list of options synthesized by the International Negotiating Committee secretariat.
