  Norway is a country rich in energy resources. Most domestic energy consumption is based on hydroelectricity, with low production costs. Since the beginning of the industry, more than a century ago, the Norwegian government has taken control over the ownership and governance of the power sector. However, the sector was reformed in the 1990s, with the introduction of free trade and a power exchange in the wholesale market. In 1969, oil and gas were discovered on the Norwegian continental shelf. Also, this sector has been regulated and controlled by the government. Income from oil and gas exports have created large revenues for the Norwegian state. The chapter discuss the political and administrative challenges in governing these two key sectors of Norwegian economy and society. In addition, two external challenges are highlighted: first, the somewhat conflicted energy relations with the European Union, as Norwegian interests as an oil and gas export clashed with EU Members’ interests, as oil and gas importers. Second, Norway is in a paradoxical situation as an internationally active supporter of climate action and, at the same time, a large oil and gas exporter. Keywords: energy, oil, gas, hydropower, climate, European Union.

  This article discusses the possibilities and obstacles for a cost-effective implementation of policies that will lead to a significant reduction in global CO2 emissions from the use of oil. The structural conditions and economic consequences of changing national or regional energy systems vary dramatically. In addition, there are a large number of actors with strong interests along the energy value chain that may potentially halt, delay or alter the implementation of the Paris treaty. We analyze these issues by first locating oil in the overall energy system, then identifying possibilities and obstacles at various stages of the oil value chain, and finally by contextualizing global oil by discussing whether and how it may be affected by geopolitics and regional conflict. In brief, our argument is that developments in consumption volumes and patterns will be most important. Market forces are vital, but they are influenced by politics and public policy outcomes. Transportation is the most important sector for oil consumption, with changes in transport behavior, modes and technology being vital drivers. The behavior of investors will be a decisive factor in shaping the production side of the oil system. If investments go down as a response to lasting low oil prices and/or because investors decide to turn to green economy options, the supply of oil will logically shrink. On the other hand, the growth and development aspirations of a rapidly growing population in developing countries are likely to stimulate demand and thus increase exploration, production and subsequently the price. Finally, we emphasize the importance of (geo)politics influencing all aspects of the value chain of oil.

  Dag Harald Claes tar i artikkelen EØS-avtalen � mellom diplomati og demokrati � utgangspunkt i forskjellene som kjennetegner demokratiske og diplomatiske beslutningsprosesser. Mens demokrati forutsetter representasjon og deltakelse, forutsetter diplomati hemmelighold, diplomatenes hegemoni og fleksibilitet i forhandlinger. Disse kriteriene lar seg ikke alltid fullt ut forene. EØS-avtalen faller mellom to stoler siden dens saksinnhold og omfang tilsier en demokratisk beslutningsprosess, mens dens form preges av diplomatiets logikk. Artikkelen argumenterer for at dette ikke bare gjelder EØS-avtalen, men at motsetningen mellom diplomati og demokrati generelt sett er svekket. EØS-avtalen føyer seg dermed inn i en bredere tendens, snarere enn å representere et unntak i det politiske systemet.

  The first two chapters of the book cover the two concepts: climate and energy. Chapter 1 is concerned with the history of climate science and the essence of the phenomenon called the greenhouse effect. It briefly describes the consequences of climate change, and in a bit more detail, the causes behind the increase over the last 150 years. Chapter 2 is an introduction to energy, using some physics, and specifically, a description of the various energy sources and the energy system. The chapter also discusses the causes and consequences of the growth in energy consumption. In Chapters 3 and 4, we turn to international climate politics, using two key focal points in the study of International Relations, the conditions for international cooperation and the role of international institutions. Chapter 3 describes the evolution of climate cooperation among states and discusses how a healthy climate is a collective good for all countries and thus exposes climate cooperation to the individual incentive of free riding. Chapter 4 is dedicated to the role of the UNFCCC in light of theories on the character and role of institutions in international politics. Chapter 5 compares states’ climate policies and relates this to their energy mix and other economic factors. The chapter is mainly descriptive and is intended as a factual basis for the discussions in the following chapters. Chapter 6 relates climate policies to characteristics of political systems and discusses the thesis that democracies have more ambitious climate policies than autocracies. The chapter also discusses the relations between governments and interest groups and their implications for climate politics. Chapter 7 describes the democratic political process from aim to action, emphasizing the agenda-setting role of the Intergovernmental Panel on Climate Change, the development of national climate policies, and discusses the challenges of making rational and consequential political decisions. Chapter 8 focuses on the political instruments available to create GHG emission reductions in the various sectors of energy consumption. Chapter 9 presents two economic perspectives: market economics and institutional economics and discusses economic models of optimal climate change policies and the institutional challenges in the fossil fuel sectors. Chapter 10 focuses on the political use of economic instruments to reduce GHG emissions, such as a carbon tax, emission trading systems, and supply-side policies. Chapter 11 discusses moral and ethical aspects related to climate change, from a utilitarian and egalitarian liberal perspective, and how climate relates to international and intergenerational justice. Chapter 12 is devoted to legal aspects of climate change. Based on principles of human rights, the chapter discusses international and national climate law and legislation.
