Europe is facing a climate and environmental crisis. To respond to this, the European Commission has launched several programmes, which aim to increase sustainability and environmental protection. This aim has been condensed into the policy document that is the European Green Deal. The European Green Deal sets out the aim of making the Union’s economy climate neutral, while improving environmental protection and protecting biodiversity. To this end, several different sectors of the economy need to be overhauled.  In EU Law, a key policy area is to protect free competition. Article 101 TFEU sets out that agreements between undertakings which have as their object or effect the prevention, restriction or distortion of competition are prohibited. Similarly, Article 102 TFEU prohibits abuse by an undertaking of a dominant position.  This thesis explores what happens when competition law thus intersects with the environmental policy of the Union. The thesis identifies two main situations  of interaction. Undertakings can invoke environmental protection to justify a restriction of competition. The Union may also rely on its antitrust provisions to enforce sustainability by holding unsustainable practices as restrictive agreements or abuses of dominant behaviour, respectively, and thus prohibited by the antitrust provisions.  Generally, the thesis concludes that there is not enough information on how the Commission and the CJEU will approach arguments relating to sustainability in its antitrust assessment. The Commission’s consumer welfare standard appears to limit environmental integration to points where a certain factor results affects the environment or sustainability on the one hand, and consumer welfare on the other. The lack of information, moreover, is in itself an issue as undertakings may abstain from environmental action if they believe they will come under scrutiny due to violations of the antitrust provisions. Therefore, a key conclusion in the thesis is that the Commission and the CJEU should set out clear guidelines for environmental action by undertakings, in relation to the antitrust provisions. Similarly, the Commission appears to be cautious to use antitrust as a tool against unsustainable practices. The Commission has, however, recently decided to open an investigation into agreements which limit sustainability, which shows that the picture may be changing.

Competition and data protection law are two powerful regimes simultaneously shaping the use of digital information, which has given rise to new interactions between these areas of law. While most views on this intersection emphasize that competition and data protection law must work together, nascent developments indicate that these legal regimes may sometimes conflict.  In the first place, firms faced with antitrust allegations are to an increasing extent invoking the need to protect the privacy of their users to justify their impugned conduct. Here, the conduct could either be prohibited by competition law despite of data protection or justified under competition law because of data protection. In the EU, no such justification attempt has reached court-stage, and it remains unclear how an enforcer ought to deal with such a claim. In the second place, competition law can mandate a firm to provide access to commercially valuable personal data to its rivals under a competition law remedy. Where that is the case, the question arising in this connection is whether an enforcer can and should design the remedy in a way that aligns with data protection law. If so, the issue remains of how that ought to be done. The task of the thesis has been to explore these issues, legally, economically, and coherently.  The thesis has rendered four main conclusions. First, data protection has a justified role in EU competition law in two ways. On the one hand, enhanced data protection can increase the quality of a service and may thus be factored in the competitive analysis as a dimension of quality. On the other, data protection as a human right must be guaranteed in the application of competition law. Second, these perspectives can be squared with the criteria for justifying competition breaches, in that data protection can be invoked to exculpate a firm from antitrust allegations. Third, in that context, the human rights dimension of data protection may entail that the enforcer must consider data protection even if it is not invoked. However, allowing data protection interests to override competition law in this manner is relatively inefficient as it may lead to less innovation, higher costs, and lower revenues. Fourth, the profound importance of data protection in the EU necessarily means that enforcers should accommodate data protection interests in designing competition law remedies which mandate access to personal data. This may be done in several ways, including requirements to anonymize data before providing access, or to oblige the firm to be compliant with data protection law in the process of providing access. The analysis largely confirms that anonymization is the preferable option.

Le secteur des assurances est protéiforme : il comprend plusieurs opérateurs dont l’intégration dans le paysage économique et juridique s’est accentuée ces dernières années et ne cesse de s’imposer. Les compagnies d'assurance déploient elles-mêmes des activités d’assurance multiples. Depuis les années cinquante les différents régimes d’assurances maladie, vieillesse, chômage – obligatoires, complémentaires – sont exploités par certains organismes assureurs (mutuelles et institutions de prévoyance). Ces organismes développent leurs activités sur des marchés dont le caractère économique n’est pas toujours évident. Si les assurances vie par exemple, ne soulèvent guère de difficulté d’insertion sur un marché concurrentiel, peut-on en revanche considérer que les régimes complémentaires et légaux d’assurance maladie opèrent sur un marché économique ? Cette question conduit à s’interroger sur la soumission du secteur des assurances au droit de la concurrence et son éventuelle unicité de régime. Deux points sont étudiés, en premier lieu, il s’agit de confronter le secteur des assurances à la vision extensive des autorités européenne et nationale sur les critères d’applicabilité du droit de la concurrence. Cette approche est vérifiée auprès de tous les opérateurs proposant des produits et services qualifiés d'assurance. En second lieu, sont examinées l'application du droit de la concurrence au secteur des assurances et leurs exemptions spécifiques. Cette étude prend en compte l’ensemble du droit de la concurrence : pratiques anticoncurrentielles, droit des concentrations économiques et aides d’État. Elle s’appuie essentiellement sur le droit européen et français de la concurrence. / The insurance industry is protean : it includes several operators whose integration into the economic and legal landscape has intensified in recent years and continues to impose itself. Insurance companies themselves deploy multiple insurance activities. Since the 1950s, some insurers have exploited differents insurance schemes such as, health, old age, unemployment (whether compulsory or complementary). These organizations develop their activities in markets whose economic character is not always the most obvious. If life insurance, for example, does not present any difficulty in entering a competitive market, can we also consider that the supplementary and statutory health insurance schemes operate similarly in an economic market ? This question leads up to wonder about the submission of the insurance sector to competition law and its possible uniqueness of regime. Two points are studied, firstly, the question of confronting the insurance sector with the extensive vision of the European and national authorities. Secondly, an examination of the application of competition law to the insurance sector and the justification for different treatment. This study takes into account the whole of competition law : antitrust practices, economic concentrations and state aids. It is essentially based on European and French competition law.

Copyright law is a special category of civil law which, with the upswing of the Internet, has become important for different types of stakeholders in the global information society. The 'participative web' operates with content generated by users. This user-generated content has often disputable origins in terms of copyright clearance. The Internet has opened the possibility for developing new forms of communication between anonymous or individual users who are not easily identifiable. Especially peer-to-peer file sharing and recently the information services offered and operated by the so-called 'cyberlockers' are the reason of questioning the role of copyright protection online which needs a beneficial solution. Copyright infringement in the era of information society is a complex phenomenon with a multiplicity of contributing factors like the importance of information data with big business potential, personal attitudes shown by internet users towards the value and scarcity of intellectual property, or legal responsibility of internet service providers (ISP) who paradoxically act from the safety of the so-called safe harbours as intermediaries of information exchange, representing a new element in the communication chain between rights holders and users. Commercial and business models operating...
