  32. 32. Political Context• 1972: Stockholm (first UN conference on the Human Environment). Establishment of UNEPPrinciple 1Man has the fundamental right to freedom, equality and adequate conditions of life, in an environment ofa quality that permits a life of dignity and well-being, and he bears a solemn responsibility to protect andimprove the environment for present and future generations. d.Principle 2The natural resources of the earth, including the air, water, land, flora and fauna and especiallyrepresentative samples of natural ecosystems, must be safeguarded for the benefit of present and futuregenerations through careful planning or management, as appropriate.Principle 3The capacity of the earth to produce vital renewable resources must be maintained and, whereverpracticable, restored or improved.Principle 5The non-renewable resources of the earth must be employed in such a way as to guard against thedanger of their future exhaustion and to ensure that benefits from such employment are shared by allmankind.Principle 8Economic and social development is essential for ensuring a favorable living and working environment forman and for creating conditions on earth that are necessary for the improvement of the quality of life. 32
  33. 33. Principle 11The environmental policies of all States should enhance and not adversely affect the present or futuredevelopment potential of developing countries, nor should they hamper the attainmentof better living conditions for all, and appropriate steps should be taken by States and internationalorganizations with a view to reaching agreement on meeting the possible national and internationaleconomic consequences resulting from the application of environmental measures.Principle 14Rational planning constitutes an essential tool for reconciling any conflict between the needs ofdevelopment and the need to protect and improve the environment.Principle 18Science and technology, as part of their contribution to economic and social development, must be appliedto the identification, avoidance and control of environmental risks and the solution of environmentalproblems and for the common good of mankind.Principle 19Education in environmental matters, for the younger generation as well as adults, giving due considerationto the underprivileged, is essential in order to broaden the basis for an enlightened opinion and responsibleconduct by individuals, enterprises and communities in protecting and improving the environment in its fullhuman dimension.Principle 20Scientific research and development in the context of environmental problems, both national andmultinational, must be promoted in all countries, especially the developing countries.Principle 22States shall cooperate to develop further the international law regarding liability and compensation for thevictims of pollution and other environmental damage caused by activities within the jurisdiction or controlof such States to areas beyond their jurisdiction. 33
  34. 34. Political Context• 1980s: several intergovernmental conferences on CC are organized• 1987: Brundtland report• 1988: IPCC is established (by WMO and UNEP)• 1990: First Assessment Report by IPCC• 1992: Earth Summit (Rio) • Agenda 21 • Conventions on Climate, biodiversity and desertification 34
  35. 35. UNFCCCIntroduced in 1992 in Rio at the ‘Earth Summit’. It commits governmentsto a voluntary “non-binding aim” to reduce atmospheric concentrationsof greenhouse gases to prevent man-made interference with Earth’sclimate system.The Convention entered into force on the 21st of March 1994 and hasbeen ratified by 196 countries.The Convention divides countries (referred to as parties) into three main groupsaccording to differing commitments:Annex I: Include the industrialized countries.Non-Annex I: This group is comprised of mostly developing countries. The 49countries classified as least developed countries (LDCs) by the United Nations aregiven special consideration under the Convention on account of their limitedcapacity to respond to climate change and adapt to its adverse effects. 35
  36. 36. Political Context 36
  37. 37. The Kyoto Protocol• Protocol to the UNFCCC• Inspired by (US) The Clean Air Act (market based instruments)• First Draft of a Global Emissions Trading System• Cap and Trade system • Target emission level: 5.2% below 1990 emissions on average during “First Commitment period” 2008 – 2012• Two categories of countries: Capped countries (developed countries) a/o all EU members, Russia, Ukraine, Japan, Canada, New Zealand, Australia: • Targets to reduce emissions Non-capped countries (a/o Brazil, China, India): • No obligation to reduce, but incentive to do so through the “Clean Development Mechanism”....• Complex rules to define the baseline 37
  38. 38. The Kyoto Protocol 38
  39. 39. What is in the Copenhagen Accord?The Copenhagen Accord is a short single document of just over two pages.• On the politics: acknowledgement of the seriousness of the problem and need for urgent collective action in line with existing principles• On the science: endorsement of the IPCC’s recommendation that global temperature increase be kept below 2 deg C• On adaptation: agreement that developed countries will provide adequate and predictable financial, technical and capacity-building support to developing countries.• On developed country mitigation: agreement that Annex 1 parties will commit to quantified economy–wide emission reduction by 2020 (although with no individual or aggregate targets given).These targets as well as financing to support developing country climate action, are to be monitored, reported and verified.• On finance levels: commitment by developed countries to provide US$30 billion in short- term financing between 2010 and 2012 and to mobilize US$100 billion per annum by 2020. This will be from public, private, multilateral and alternative sources. Funding will be used for mitigation, adaptation, technology transfer and capacity-building in developing countries. 39
  40. 40. Durban conference agreement on a second commitment period for the Kyoto Protocol (under which developed countries would take on legally-binding commitments post-2012); progress on a broader, comprehensive agreement that includes all major emitters progress in operationalizing new institutions such as the Technology Mechanism and Green Climate Fund Japan, Canada and the Russian Federation have all recently declared that they will not join in a second commitment period under the Protocol. With the US never ratifying, only a diminished group —the EU, Norway, Switzerland and a few others— now appear willing to sign on the dotted line 40
  41. 41. EU Climate Policies – 20/20/20In 2007 EU leaders made a unilateral commitment that Europe would cut its emissionsby at least 20% of 1990 levels by 2020. This commitment is being implemented througha package of binding legislation.The EU has also offered to increase its emissions reduction to 30% by 2020, oncondition that other major emitting countries in the developed and developing worldscommit to do their fair share under a future global climate agreement. This agreementshould take effect at the start of 2013 when the Kyoto Protocols first commitmentperiod will have expired. 41
  42. 42. Zoom on carbon markets 42
  43. 43. Internalize externalities3 main approaches- Standards and regulations- Pigouvian Tax/subsidies- Define property rights and establish a market (Coase, 1960)(e.g. SO2 and NOx allowances in the US, CO2 market in the EU…) Brohé et al., 2009, Carbon Markets

  62. 62. EU Emission Trading System political context • Kyoto Protocol Ratification • Incertitude over the Entry Into Force of the Protocol • Failure of a Carbon Tax • Development of Different National Initiatives (UK, Denmark) 62
  63. 63. CharacteristicsThe principal response from the EU to achieve Kyoto targets in EU MS• EU has passed through its obligations and imposed limits for greenhouse gas emissions on site level.• The EU ETS is therefore a sub-market of the Kyoto market.  +10,000 installations in the EU (main emitters)  Cap and Trade system:  Installations are entitled EU Allowances (EUA)  At the end of each year, companies have to surrender an EUA for each ton of emissions (CO2) they emit  High penalty for non compliance - EUR 100/ton CO2  3 phases/ periods: 2005 - 2007 / 2008 - 2012 / 2012 – 2020, more to follow 63
  64. 64. Characteristics• Directive 2003/87/EC• National Allocation Plan (over-allocation, favoritism, complexity)• Linking Directive (EUA=CER=ERU)• Monitoring and reporting (calculate or measure)•Registry and CITL• Penalties (no price cap!) 64

  72. 72. Criticisms of markets: use of discount rates 72 Brohé et al., 2009, Carbon Markets
  73. 73. Criticisms of carbon markets: use of discount rates • High uncertainties even in accounting (several gases, uncertain GWP, deforestation and LULUCF accounting rules) • High complexity ( not democratic, a few experts and groups with vested interests control the market) + risk of fraud • Irrationality • Do not work for diffuse sources 73
