20.24 议事机构文件方面出现差异的主要原因如下：(a) 环境政策委员会和附属机构的文件，原因是委员会决定将其 2018 年年度会议改在 2019 年 1 月举行；(b) 《在环境问题上获得信息、公众参与决策和诉诸法律的公约》缔约方会议和附属机构的文件，以及《公约污染物释放和转移登记册议定书》缔约方会议和附属机构的文件，原因是在各机构决定接受缔约方和公众的临时来文和由其各自遵约委员会审查的请求后，对文件的需求减少。
20.24 The variance in parliamentary documentation was driven mainly by documentation for: (a) the Committee on Environmental Policy and subsidiary bodies, owing to the decision of the Committee to move its 2018 annual session to January 2019; and (b) documentation for the Meeting of the Parties to the Convention on Access to Information, Public Participation in Decision -making and Access to Justice in Environmental Matters and subsidiary bodies and the Meeting of the Parties to the Protocol on Pollutant Release and Transfer Registers to the Convention and subsidiary bodies, owing to lower demand for documents following decisions by the bodies to accept ad hoc communications and requests for review from the parties and members of the public for review by their respective compliance committees.
