  10. Adaptation or Mitigation?

  11. Who Emits Greenhouse GasesToday and tomorrow

  12. Per-Capita Emissions of CO2 (Burning of fossil fuels and cement production, 1999) 10 9 8 7 5.5 6 metric tonnes Carbon per person 5 3.93 4 2.69 2.63 2.49 3 2.46 2.29 2.04 2 2 1.05 0.61 1 0.3 0 UK Italy USA India China Korea Japan Russia Mexico Ukraine Canada Germany Data source: Gregg Marland, Tom Boden, and Bob Andres Oak Ridge National Laboratory, University of North Dakota

  13. International Treaties: Framework Convention System: UNFCCC • United Nations Framework Convention on Climate Change • signed in 1992 (“Earth Summit”) • Content • Avoid “…dangerous anthropogenic interference…” in the climate system • Industrialized Nations • Aim to stabilize emissions at 1990 levels • Pay into a fund to compensate developing countries • File reports • Developing Countries • Compensated with “agreed incremental cost” of compliance • File reports • All Countries Agree to Keep Talking

  14. International Treaties: Framework Convention System: Kyoto • Treaty signed in 1997; finalized in 2001 • Basket of six greenhouse gases (not just CO2) • Emission Cuts for 38 industrialized countries • Against 1990 baseline: +10% to -8% (average: 5.2% cut) • “targets and timetables” • Applies only to 2008-2012 “budget period” • Developing countries exempt • “opt in” through Clean Development Mechanism (CDM) • “What, When and Where Flexibility”

  15. Properties of Major Greenhouse Gases • CO2 does not have a single lifetime—some processes that remove CO2 occur rapidly; others require centuries. The values for CH4 and N20 are adjustment times • including feedbacks of emission on lifetimes. CO2 radiative forcing is for small changes from current concentrations (370 ppmv). 2050 radiative forcing calculations • are % of total anthropogenic (including ozone depletion effects) for SRES B2 scenario, total forcing in 2100 of 3.73 Wm-2. Other Scenarios do not much affect the • allocation of forcing among these gases. Source: IPCC Working Group 1. 2001. Tables 6.7 & 6.14.

  37. Company Initiatives

  38. AEP • “IGCC technology appears to have the greatest potential for meeting AEP’s long term goals. During the course of our evaluation, the company concluded that accelerating IGCC technology development to reach commercial availability by 2015 or before must become a high priority for AEP.” Source: AEP. “An Assessment of AEP’s Actions to Mitigate the Economic Impacts of Emissions Policies.” August 31, 2004.

  39. CO2 Capture

  40. AEP Ohio River Valley CO2 Storage Project - Mountaineer Plant

  41. Southern Company: Technology and Innovation • Integrated Gasification Combined Cycle (IGCC) • Power Systems Development Facility (PSDF) • “The total plant cost for a 500-MW power plant with a subcritical steam cycle is projected to be less than $850/kW with an efficiency of almost 47 percent (HHV). Such a plant could produce electricity more economically than a natural gas combined cycle as early as 2006.” • Orlando Utilities Commission • SCR Development for high alkaline ashes • Mercury Control Research • Full-scale testing of Activated Carbon Injection • Development of a Fine Particulate Agglomerator • NuStart – Nuclear Consortium
