| A major problem being faced by human society is that the global temperature is believed to be rising due to human activity that releases carbon dioxide to the atmosphere; i.e., global warming. The major culprit is thought to be fossil fuel burning, which is releasing increasing amounts of carbon dioxide in the atmosphere. The problem of increasing atmospheric carbon dioxide can be addressed a number of ways. One of these is forestry and forest management. This paper examines a number of current issues related to mitigating the global warming problem through forestry. First, the overall carbon cycle is described, and the potential impact of forests on the buildup of atmospheric carbon is examined. A major focus is the means by which forests and forest... |

| While the rest of the world has pursued absolute emissions limits for greenhouse gases, the Bush administration has proposed an alternative policy formulation based, among other things, on reducing emissions intensity-that is, emissions per dollar of real gross domestic product. Critics of this formulation have denounced the general idea of an intensity-based emissions target, along with its voluntary nature and weak targets. This raises the question of whether intensity-based emissions limits, distinct from the other features of the Bush initiative, offer a useful alternative to absolute emissions limits. This paper makes the case that they do, based on how emissions targets are framed. The argument draws on four key observations: greenhouse gas emissions... |

| The Carbon Farming Initiative (CFI) and other carbon trading programs have been promoted as alternative sources of income for agricultural producers, particularly those on marginal land. This paper presents the results of a bioeconomic model developed to compare the relative returns from a beef enterprise against changing regrowth management practices to sequester additional carbon and sell carbon offsets. The model is constructed based on a 1000 hectare parcel of land in Central Queensland and is calculated for two landtypes; Brigalow and Eucalypt. Assuming zero transaction costs and a 20 year contract period, a carbon-cattle enterprise has higher returns that a cattle-only enterprise at relatively low carbon prices for both land types. However, results... |

| Carbon capture and storage (CCS) technologies remove carbon dioxide from flue gases for storage in geologic formations or the ocean. We find that CCS is technically feasible and economically attractive within the range of carbon policies discussed domestically and internationally. Current costs are about $200 to $250 per ton of carbon, although costs are sensitive to fuel prices and other assumptions and could be reduced significantly through technical improvements. Near-term prospects favor CCS for certain industrial sources and electric power plants, with storage in depleted oil and gas reservoirs. Deep aquifers may provide an attractive longer-term storage option, whereas ocean storage poses greater technical and environmental uncertainty. Vast... |

| Forestry has been considered to have potential in reducing the atmospheric concentration of carbon dioxide by sequestrating carbon in above-ground timber and below-ground roots and soil. This potential has been noted in the Kyoto Protocol, which identified specific forestry activities for which carbon sequestration credits could be obtained. To date, a few forestry efforts have been undertaken for carbon purposes, but most of these efforts have been on a small scale. Proposals have been under discussion, however, that would result in the creation of very large areas of new forest for the purpose of offsetting some of the additional carbon that is being released into the atmosphere. Concerns are expressed, however, that large-scale sequestration operations... |

| The uncertainty surrounding both costs and benefits associated with global climate change mitigation creates enormous hurdles for scientists, stakeholders, and decision-makers. A key issue is how policy choices balance uncertainty about costs and benefits. This balance arises in terms of the time path of mitigation efforts as well as whether those efforts, by design, focus on effort or outcome. This paper considers two choices-price versus quantity controls and absolute versus relative/intensity emissions limits-demonstrating that price controls and intensity emissions limits favor certainty about cost over climate benefits and future emissions reductions. The paper then argues that in the near term, this favoritism is desired. |

| An RFF Workshop brought together experts from around the world to assess the feasibility of using biological sinks to sequester carbon as part of a global atmospheric mitigation effort. The chapters of this proceeding are a result of that effort. Although the intent of the workshop was not to generate a consensus, a number of studies suggest that sinks could be a relatively inexpensive and effective carbon management tool. The chapters cover a variety of aspects and topics related to the monitoring and measurement of carbon in biological systems. They tend to support the view the carbon sequestration using biological systems is technically feasible with relatively good precision and at relatively low cost. Thus carbon sinks can be operational. |
