Europe—Given that Europe is an assembly of sovereign nations, what actions of the European Environmental Agency will be most valuable in correcting the pollution problem?
Answer:
The costs of non-sovereignty are high.
European countries are increasingly vulnerable to external pressure that prevents them from exercising their sovereignty. This vulnerability threatens the European Union’s security, economic health, and diplomatic freedom of action, allowing other powers to impose their preferences on it.
To prosper and maintain their independence in a world of geopolitical competition, Europeans must address the interlinked security and economic challenges other powerful states present – without withdrawing their support for a rules-based order and the transatlantic alliance. This means creating a new idea of “strategic sovereignty”, as well as establishing institutions and empowering individuals that see strategic sovereignty as part of their identity and in their own interest. Most fundamentally, the EU needs to learn to think like a geopolitical power.
The long-term goal of the EU is to reach air quality levels that do not pose unacceptable hazards to the environment or adverse effects on human health.
What is European Environment Agency?The European Environment Agency (EEA) is responsible for collecting statistics on air pollution for the EU and aids in the enforcement of laws pertaining to air emissions and air quality. The EEA also helps with the assessment of EU air pollution policies and the formulation of long-term plans to enhance Europe's air quality.
The work of EEA focuses on:
making a variety of air pollution data available to the public, assessing trends in air pollution and related laws and regulations in Europe, examining the trade-offs and interactions between policies relating to air pollution and those relating to climate change, transport, energy, and industry.Learn more about the European Environment Agency, from:
