The Clean Air Regulatory Agenda (CARA) Mercury Science Program was developed to provide scientific information to support regulatory activities and accountability pertaining to atmospheric emissions of mercury in Canada. The first phase of the science program, entitled "Setting-the-Baseline", sought to achieve the following: identify key indicators of the state-of-the-Canadian environment with respect to the transport, fate and effects of mercury; define these indicators; and, understand the processes that relate these indicators to anthropogenic emissions of mercury. To achieve these outcomes, a consultative process was used to identify the scientific needs of the agenda for mercury; understand Canada's scientific capacity; and, develop a plan to fulfill these scientific needs. The science plan that emerged from this process was structured around the themes of atmospheric monitoring, landscape-based risk assessment, ecological risk assessment, ecosystem modeling, and trends. Implementation of the science plan necessitated a multi-disciplinary and extensively partnered program. To date, the CARA Mercury Science Program is producing coordinated science at the national-scale that aims to directly assess the effectiveness of the CARA for mercury and for many of Canada's other mercury-related policies.
清洁空气监管议程（CARA）汞科学计划旨在提供科学信息，以支持与加拿大大气汞排放有关的监管活动和问责制。该科学计划的第一阶段题为“设定基线”，旨在实现以下目标：确定与汞的迁移、归宿和影响有关的加拿大环境状况的关键指标；定义这些指标；并了解将这些指标与人为汞排放联系起来的过程。为了实现这些目标，采用了协商进程来确定汞议程的科学需求；了解加拿大的科学能力；并制定满足这些科学需求的计划。从这个过程中产生的科学计划是围绕大气监测、基于景观的风险评估、生态风险评估、生态系统建模和趋势等主题构建的。科学计划的实施需要多学科和广泛合作的计划。迄今为止，CARA 汞科学计划正在全国范围内开展协调一致的科学研究，旨在直接评估 CARA 对汞以及加拿大许多其他与汞有关的政策的有效性。
