ANS-EN-MS-MMN: Good environmental status is the combination of well-functioning marine ecosystems, their good health and the environmental sustainability of their use for human activities. The definition of good environmental status takes into account the existence of human activities at sea or on land that have an impact on the environment. As such, it is not a state unaffected by human activities, sometimes called "pristine". In defining good environmental status, certain contextual elements need to be taken into account. In addition to the existence of anthropogenic pressures, it is therefore necessary to consider their impacts on the environment, the long-term or short-term natural variability of ecosystems and their resilience, and global changes, in particular climate change. On the basis of the content elements of the Directive, France has chosen to define good environmental status as the long-term level of ambition for the environmental status of the marine environment, i.e. the acceptable level of impact of human activities on environmental status that does not affect the proper functioning of ecosystems. The methodology for defining good environmental status distinguishes between two bases: 1: the description of the Good Environmental Status at the level of descriptors and, where appropriate, at the level of criteria. 2: the characterization of the Good Environmental Status, which includes several elements: - the identification of "units of assessment" and relevant scales ; - definition of the method for identifying issue areas/characteristic areas ; - The development of indicators to judge the achievement of the EEB for the marine environment, based on the above choices; - the definition of levels/thresholds/trends associated with these indicators and the setting of these levels/thresholds/trends; - the development of an intra-descriptor aggregation method. It should be noted that the proper functioning of an ecosystem is a scientific concept, based on an ecosystem approach, which can be qualified or even quantified, in some cases today, in other cases in the future, subject to further studies, research and data acquisition. This definition will have to be revised every 6 years on the basis of new knowledge and data and will have to take into account the evolution of anthropogenic pressures and global changes. The effects of climate change are being felt on the marine environment and its functioning: they will be taken into account in the revision of the definition of Good Environmental Status as part of the context.

Non-native species introduced through human activities are at levels that do not disturb ecosystems.

Good ecological status is achieved when the frequency and intensity of new introductions of non-native species through human activities are reduced to a minimum level.

Good ecological status is achieved when the impacts of invasive non-native species are minimized.

The indicator for criterion 2.1 relevant to characterising good ecological status is defined as follows : Indicator 2.1.1: Trends in the abundance, temporal evolution and spatial distribution in the natural environment of non-native species, in particular invasive non-native species, especially in areas at risk, in relation to the main vectors and pathways of propagation of such species.

The indicator for criterion 2.2 relevant to characterising good ecological status is defined as follows: Indicator 2.2.2: Impacts of invasive non-native species at the species, habitat and ecosystem levels, where these can be determined.

The aggregation rules at the level of the descriptor will be clarified, where appropriate, as a result of additional studies, as provided for in Article 4 of the Order of 17 December 2012 concerning the definition of good environmental status of marine waters. These elements will be developed with a view to updating the definition of good environmental status by 2018.

The parameters associated with the indicator, as well as the levels and trends corresponding to good environmental status, will be specified for the indicator associated with criterion 2.1 following further studies, as provided for in Article 4 of the Order of 17 December 2012 on the definition of good environmental status of marine waters. These elements will be developed with a view to updating the definition of good environmental status by 2018.
