Increasing environmental pressure from production and consumption of products and services is starting to affect Earth System stability. Thus, the Planetary Boundaries framework introduced a set of absolute boundaries for keeping the Earth System stable and delimiting a safe operating space for humanity. The sum of environmental pressures associated with human activities should not exceed the safe operating space. This includes utility companies whose activities relate to supply of water and treatment of waste- and stormwater. This study conducted an absolute environmental sustainability assessment (AESA) of a Danish utility company to evaluate if it could be considered absolutely sustainable relative to an assigned share of the safe operating space (SoSOS). The AESA evaluated the company's impacts relative to an assigned share of the Planetary Boundaries and relative to specific local boundaries for nitrogen and phosphorous emissions. Results showed that the assigned SoSOS was exceeded for 10 of 18 impact categories, for example, climate related boundaries were exceeded by up to a factor 7.8 while local nitrogen and phosphorus boundaries were exceeded by ca. a factor 16. The AESA can indicate to which degree the company exceeds its assigned SoSOS for certain impact categories and the processes and life-cycle stages to focus on to become absolutely sustainable. This information is crucial for deriving specific impact reduction targets as part of environmental strategies for companies to become sustainable in an absolute sense.

丹麦公用事业公司相对于行星边界的绝对环境可持续性评估

产品和服务的生产和消费带来的环境压力越来越大,正开始影响地球系统的稳定性。因此,行星边界框架引入了一组绝对边界,以保持地球系统稳定并为人类划定安全的运行空间。与人类活动相关的环境压力总和不应超过安全操作空间。这包括其活动与供水以及废水和雨水处理相关的公用事业公司。本研究对一家丹麦公用事业公司进行了绝对环境可持续性评估 (AESA),以评估相对于安全操作空间 (SoSOS) 的指定份额是否可以被视为绝对可持续。AESA 评估了该公司的 s 影响相对于指定份额的行星边界以及相对于氮和磷排放的特定局部边界。结果表明,18 个影响类别中的 10 个超过了指定的 SoSOS,例如,气候相关边界超过了 7.8 倍,而当地氮和磷边界超过了约 7.8 倍。一个因素 16. AESA 可以表明公司在何种程度上超出了其指定的 SoSOS,在某些影响类别以及流程和生命周期阶段要重点关注以实现绝对可持续。这些信息对于制定具体的减少影响目标至关重要,作为公司环境战略的一部分,以实现绝对意义上的可持续发展。结果表明,18 个影响类别中的 10 个超过了指定的 SoSOS,例如,气候相关边界超过了 7.8 倍,而当地氮和磷边界超过了约 7.8 倍。一个因素 16.
