Four Propositions about Climate policy and its Interactions with the Global Steam Coal Market

Proposition 1: The relevant mechanisms to be considered are pure demand and supply effects that will be called “market adjustments”.

Proposition 2: A global and binding climate agreement is crucial to avoid negative market adjustments from unilateral demand reducing policies.

Proposition 3: A faster implementation of the CCS technology would have the greatest benefits on emissions reductions.

Proposition 4: Unconventional supply-side climate policies need to be considered.

Types of Carbon Leakage and “Market Adjustments”

Market adjustments are broader and include both negative and positive effects

Modeling Approach: COALMOD-World model

COALMOD-World model (equilibrium model in MCP format) with profit maximizing players with respect to sold quantities and investments.

- Model players:

Producers who produce, transport overland and sell the coal to local demand nodes or to the exporters.

Exporters operate the export terminal, transport the coal over sea and sell it to demand nodes with import terminal.

- The players can also invest to expand their production, export or transport capacities that are constrained.

- The model is multi-period and runs till 2030 in 5 years steps calculating yearly market equilibria.

Specification:

- 41 demand nodes, 25 producers, 14 Exporters.

- Virtually all demand for steam coal in the world.

- Models global international seaborne trade as well domestic markets such as China, USA, Russia…

Unilateral European Climate Policy

• In this scenario of Unilateral European climate policy the European Union goes a step further and aims at reducing CO2 emissions of 30% compared to the level of 1990 by 2020 with further reductions in the future.

• The leads to following steam coal demand reduction in comparison to the two reference scenarios Current Policies and New Policies:

CCS Fast Roll-out Starting in 2020

• Prerequisites: Technological breakthroughs, a favorable regulatory framework, strong political support.

• Implementation: installed capacities of coal power plants with CCS projected by the WEO IEA (2010) in the 450 ppm scenario are put in place five years earlier.

• Half of capacity replaces existing older coal power plants, the other half is integrated in the power system as additional capacity, successfully competing with other technologies. CCS power plants are assumed to have 38% efficiency and a capacity factor of 82%.

• Two demand shocks: half of the CCS capacity that is added to the coal demand and the lower efficiency of CCS power plants requires additional coal to produce the same amount of energy.

Yasuní-type supply-side policy in Indonesia

The Yasuní-ITT initiative was proposed by the Ecuadorian government.

• Goals: combating global warming, protecting biodiversity and indigenous people, implementing a sustainable social and energetic development.

• Measures: No exploitation oil reserves of the Ishpingo-Tambococha-Tiputini (ITT) oil field within the Yasuní National Park (20% of the Ecuadorian oil reserves)

• Financing: at least half of the earnings Ecuador would receive from exploitation. 3.635 billion USD supplied by the international community to a fund managed by the UNDP.

• Emissions savings: The initiative represents 407 Mt CO2 saved from not using the oil resource and an additional 820 Mt CO2 mitigation potential over 20 years from avoided deforestation and forest management

Scenario for Indonesia:

• Issues: Steam coal exploitation in Kalimatan is potentially endangering one of the greatest rainforests in the world and its biodiversity through deforestation and local air and water pollution. A recent publication points out that coal mining has little to no beneficial effects on the local economy (Fatah, 2008).

• Measure: Export restriction in Million tons per annum (Mtpa):

2006 to 2015 2020 2025 2030

No restriction 50 Mtpa 25 Mtpa Export ban

Conclusions and Policy Recommendation for the EU Climate Policy

• Top 1: Reach a globally binding climate agreement on the level of the non-binding commitments of the last climate conferences (Copenhagen and Cancún).

• Top 2: Support the expansion of CCS locally and globally.

• Top 3a: Go a step further in implementing a more ambitious climate policy if the goal of Top 1 is reached. Or combine with Top 3b to hedge negative market adjustment risks.

• Top 3b: Be open for unconventional supply side climate policy.

Possible Interaction between Climate Policy and Coal Markets: Intertemporal Extraction Path Change

• Change in extraction path over time? Strategic behavior of resource owners? (Green paradox, H.-W. Sinn based on assumptions of the classical Hotelling model)

No Scarcity Rent to be Expected: No Strategic Behavior Possible

Problem with this approach: more coal on earth than will ever be consumed, hence no long term scarcity rent, and an overall competitive market:Such a strategic behavior is impossible.

More relevant: Leakage effects and market adjustments between countries with different climate policies.
