Europe in 2023 This section provides an overview of Europe in 2023, compared to the long-term trends of variables across the climate system. Spotlight sections provide a detailed look at key events during the year, and a discussion of climate policy and action with a focus on human health.

25 pays sont confrontés à un stress hydrique "extrêmement élevé", selon un rapport publié ce mercredi.
Ce qui signifie qu'un quart de la population du globe utilise régulièrement 80% de ses réserves en eau.
Une situation qui nécessite d'importants investissements.

Abstract. Intergovernmental Panel on Climate Change (IPCC) assessments are
the trusted source of scientific evidence for climate negotiations taking
place under the United Nations Framework Convention on Climate Change (UNFCCC), including the first global stocktake under the Paris Agreement that will conclude at COP28 in December 2023. Evidence-based decision-making needs to be informed by up-to-date and timely information on key indicators of the state of the climate system and of the human influence on the global climate system.

Deux experts de l'équipe Milieux marins de PatriNat ont contribué à l'évaluation 2023 des indicateurs de l'état de la biodiversité marine dans l'Atlantique Nord-Est, réalisés dans le cadre de la Convention OSPAR (15 pays et l'Union Européenne).

Pour interpeler les décideurs ou pour communiquer vers le grand public sur les performances environnementales d’un pays ou d’une région, des scores simples intégrant plusieurs critères environnementaux sont de plus en plus couramment diffusés. Ces indices dits « composites » agrègent ainsi des indicateurs individuels portant sur des thématiques différentes comme le changement climatique, la qualité de l’air et de l’eau, ou la politique de protection de la biodiversité.

Global metrics for the environment

Careful measurement of environmental trends and progress provides a foundation for effective policymaking. The 2018 Environmental Performance Index (EPI) ranks 180 countries on 24 performance indicators across ten issue categories covering environmental health and ecosystem vitality. These metrics provide a gauge at a national scale of how close countries are to established environmental policy goals.

Since their adoption in 2015, the Sustainable Development Goals (SDGs), with their ambition to be universal and indivisible, have become a dominant framework to discuss development matters, especially on the international stage. This work aims at bringing information on whether or not the SDGs provide a good mapping of development priorities as expressed by countries. We develop a new analysis of the SDG framework (within the 2030 Agenda) by systematically mapping the national development priorities displayed by 121 countries in their long-term development documents.
