The Union has already ratified numerous international environmental agreements, both at global level (multilateral agreements negotiated under the auspices of the United Nations), at regional level (e.B. within the framework of the United Nations Economic Commission for Europe or the Council of Europe) and at sub-regional level (e.B. for the management of transboundary seas or rivers). Below are six examples of EIAs with some of the highest participation rates in the world. Almost all countries have laws and mechanisms in place for environmental impact assessment, and about a third of them have guidelines for strategic environmental impact assessment. Both figures represent an increase from the situation 5 years earlier. Many countries are integrating biodiversity into land use planning mechanisms. Brazil has promoted ecological-economic zoning processes at the federal, state and municipal levels, as well as for some watersheds. South Africa has completed a national spatial biodiversity assessment and is integrating biodiversity into spatial planning and economic development at the municipal level in the North-West and Western Cape provinces. While there are self-applicable international environmental agreements, they are signed by a limited number of countries.
Although the CBD is an international environmental agreement, it is mainly implemented through measures at the national level. National Biodiversity Strategies and Action Plans (NHPs) are the main instruments for implementing the Convention at the national level. NHSPs reflect how a country intends to achieve the objectives of the Convention, taking into account specific national circumstances and the measures it plans to take. The Convention requires countries to develop a national biodiversity strategy (or equivalent instrument) and to ensure that this strategy is integrated into the planning and activities of all sectors whose activities may have an impact (positive and negative) on biodiversity. So what do we need to know about environmental contracts and how can we better understand why they are important? How many multilateral environmental agreements have been signed? Data or graph of agreements by year and type (treaty, protocol, amendment). International environmental agreements are a category of treaties whose political and economic impacts go beyond their environmental impact, but many people are unaware of their specificities. The search term “What is the Paris Agreement?” reached its peak of popularity the day after the United States announced its withdrawal from the treaty. There are several additional research directions that deserve additional effort. The strategic dimension of environmental negotiations at both international and national level (voters may be invited to ratify an environmental agreement) leads to interesting problems of political economy. The absence of supranational authority requires an analysis of the new international institutions.
The possibility of broadening coalitions by linking environmental and trade negotiations requires further theoretical and empirical analysis. A dynamic framework could be better suited to address environmental problems where the stock of pollutants rather than the flux (emissions) is the decisive variable to be monitored. The analysis of the impact of transfers and thematic contexts on the size of stable coalitions should be extended to the theoretical approach, where several coalitions are allowed, and to the approach where the membership rules are endogenous. Finally, it is important to test the theoretical results with more advanced energy, economic and environmental models that capture the many asymmetries between actors, realistic cost mitigation functions and links to non-environmental issues such as trade. The presence of asymmetries between countries and the incentive for free-ride make it quite unlikely that there will be self-reinforcing global agreements, i.e. profitable and stable for all countries. An agreement may refer to an effective meeting or conference between the parties at which they reach agreement on the final terms of a contract. However, it is also commonly used to describe general agreements between governments. In all these areas, the Union is a strong supporter of international environmental action and cooperation and an active actor committed to promoting the concept of sustainable development throughout the world. In Section 4.2, we describe a simple model of environmental regulation with a single fossil fuel. In section 4.3, we extend the analysis to two resources with different pollution characteristics. Section 4.4 concludes with a discussion of the limitations of the framework and a proposal for possible analytical and empirical applications.
A final question concerns the results and impact of a specific institutional provision of a public good at the international level. .
