EESI is currently undertaking a two-year initiative, Developing Sustainable Bioenergy: A Tool to Revitalize Forest Ecosystems and Rural/Local Economies. Our goal is to develop policies and incentives that will help diversify feedstocks and technologies to build an environmentally sustainable bioenergy industry, with a focus on the utilization of wood residues, timber slash, and small-diameter, low-quality trees, from forest operations and the forest products industry.
There is a growing consensus and understanding among politicians, scientists, and other decision makers that the overwhelming threat of global climate change is and needs to be an important consideration when determining the impacts of any activity. Climate change has the potential to produce widespread and devastating repercussions throughout the environment, the economy, and society itself. This understanding provides a strong incentive for a national emphasis on increasing energy efficiency in every sector of the economy and reducing emissions of carbon dioxide and other greenhouse gases. Collectively, U.S. forests act as a colossal carbon store. Depending on the nature and extent of forest management, this carbon store can act either as a carbon source, a sink, or a carbon-neutral flux. When forests are harvested unsustainably or burn down in increasingly catastrophic wildfires, they act as carbon sources – contributing to the pool of greenhouse gases in the atmosphere and exacerbating global climate change. When annual removals, from both harvests and natural disturbances, are equal to or less than annual forest growth, forests will act as carbon-neutral fluxes or even sinks, capturing some of the atmospheric carbon and storing it as biomass. Because of the cyclic nature of this carbon store and the minimal processing required in its use, wood has the lowest carbon emissions and the greatest energy-efficiency when compared to other common structural materials, such as cement or steel. For the same reason, the energy contained in wood can be captured and used to generate heat and power with little or no carbon-emissions.
In addition to their valuable role in the carbon cycle, forests provide a number of other vital ecosystem services, filtering and storing water, building soils, reducing erosion, providing habitat, offering recreation, and protecting our communities and landscapes from catastrophic weather events. Yet the loss of forest product markets, steadily rising property taxes and rising management costs are threatening the long-term viability of our forests, both public and private, as forests are being lost to alternative land uses, such as suburban development, at an accelerating rate. The poor utilization and lack of markets for small-diameter and low quality trees make it difficult to implement silvicultural prescriptions among the full range of size classes, leading to the poor management practice known as 'highgrading' in which only trees above some minimum value are harvested. The inability to utilize these trees not only prevents good management and reduces revenue, it often totally precludes management for values other than commercial timber production, such as early-successional wildlife habitat and hazardous fuels reduction treatments. The National Fire Plan currently prescribes fuels reduction treatments for millions of acres as part of the national strategy to reduce the threat of catastrophic wildfires. The majority of these acres will never be treated due to limited budgets and the lack of an outlet for use of the thinnings.
Production of energy from woody biomass will add value to low-quality forest materials and can make it logistically possible for forest managers to successfully implement management objectives. Foresters, landowners, and local officials are increasing aware that development of wood-based energy enterprises can help to slow encroachment from urban sprawl, reduce the intensity of forest fires, improve forest health, and drive local economic development through the creation of rural jobs and markets, all while providing a clean, sustainable source of domestic energy.
Wood-based Energy Discussion Series
EESI would like your help in bringing together a diverse group of foresters, academics, NGOs, and civic officials, as well as those involved in the production of wood-based energy products, for a series of discussions on the future of wood-based energy and sustainable forest management. The primary motivation behind these discussions will be the accelerated development of a sustainable wood-based energy industry, one that complements the existing forestry infrastructure, facilitates management for a wide variety of values and objectives, contributes to local communities and reduces greenhouse gas emissions as well as our dependence on fossil fuels.
Two main goals of these discussions are:
- To define needed research for the production of sustainable wood-based energy, including such needs as national and regional biomass assessments and investigation of a wide portfolio of diverse regional feedstocks.
- To determine the principal opportunities and barriers, both political and economic, to achieving the widespread adoption of wood-based energy.
A stakeholder discussion series will help in achieving these goals by providing a forum for the sharing of information and ideas, the exploration of problems and solutions, and the building of a general consensus on the needs and conditions of the industry and our forests. In addition, the networks and contacts made as a result of these discussions will continue to serve into the future as a valuable resource to those interested or invested in wood-based energy.

March 5, 2008 - EESI has drafted a fact sheet (.PDF, Updated 04/10/08) outlining our case for including federal forests in the definition of renewable biomass within the Renewable Fuel Standard (RFS). This factsheet is a distillation of the case that EESI's Executive Director Carol Werner made in recent testimony (.PDF) before the Senate Committee on Energy and Natural Resources. We welcome your comments on this document.
February 8, 2008 - Conference Call - The purpose of this conference call was to edit and expand upon the list of knowledge gaps and research needs that had been identified during earlier conference calls and individual conversations with network members. A comprehensive and complete list of these needs, contributed to and vetted by a large group of stakeholders, will serve as an important resource for EESI when we sit down to draft concrete federal policy suggestions. Furthermore, it is an effective tool for eliciting discussion, collaboration, and information sharing among network members. Although research is still needed in nearly all aspects of bioenergy, much is known, in general, about growing and managing trees and forests. In addition, the understanding of how to effectively convert woody biomass to heat, power, and liquid fuels is growing by leaps and bounds. What aren’t very clear, however, are the standards and guidelines that are needed to craft management systems that produce biomass while sustaining thriving, healthy forest ecosystems. The research and knowledge that is most lacking, however, is that relating to biomass markets and economics. Specifically, better information is needed on biomass availability, regional pricing, harvesting and management costs, and the market-creating potential of policy incentives. The lack of reliable information on these topics itself appears to be a substantial disincentive for investment in forest bioenergy projects and businesses. Thorough, multi-layered regional biomass assessments could be conducted to include much of this information and provide an important tool to communities and individuals interested in creating energy from sustainable forestry.

November 29, 2007 - Conference Call - This discussion, among forest ecologists and silviculturists, focused on the impacts of increased biomass utilization on forest structure, ecological dynamics, and overall environmental health. The group all agreed that guidelines, best management practices, or certification schemes need to be developed to ensure that biomass harvesting is done sustainably. Existing guidelines are either vague on biomass extraction (FSC, SFI) or contain numbers that are either suspect or supported in only one location (For instance, Minnesota’s voluntary standards for biomass harvesting). The group felt that a market for biomass could affect silvicultural decision-making in a number of ways, including an increased usage of whole-tree harvesting and more widespread stand-improvement thinnings. In the west, expanded biomass markets would likely increase the incidence of fuel reduction thinnings and restoration of dangerously overstocked stands. Where site quality is too low to grow sawtimber, a high value placed on forest biomass could result in clearcutting on relatively short rotations (~30 years). This occurred about 50 years in low quality hardwood stands in Tennessee in response to the establishment of a wood-based chemicals industry. Because of the complexity of this issue and the strong differences in different forest types, it was suggested that some kind of block-funding given to states could be effective. This funding could then be used to establish programs or fund projects to assist landowners and forest managers in developing forest management systems that include sustainable extraction of low-grade forest biomass.

November 8, 2007 - Conference Call - This discussion was among a group of people actively involved in sustainable forest management and/or energy production from forest biomass. There was a consensus that increasing the use (and consequently, the value) of forest biomass has the potential to boost the quality of forest management on both private and public land. In either case, a common theme throughout the discussion was the importance of obtaining community buy-in for a project to be successful. Those projects that obtained this buy-in had two important commonalities: A) community groups were actively involved in each step of the planning and implementation processes, and B) projects were located in communities that had a history of industry and/or rural enterprises. Once again, scale was pointed out as being an important consideration. In order to be acceptable and successful, projects need to be tailored to meet the needs AND resources of the community involved – more often than not, this means small scale utilization of biomass for thermal energy or combined-heat-and-power (CHP) as opposed to large power generating facilities. There were a number of issues relating specifically to the extraction of biomass from federal forestland. Thinning is a key component of management on many federal forests, especially those at risk from catastrophic wildfire, but thinning and fuel removal treatments are costly treatments and therefore are left undone on many acres. Stewardship contracts are one possible solution. These are contracts between federal managers and private companies in which a mix of merchantable and unmerchantable trees are harvested, with the value of the services rendered offset by the value of the material removed. This is a low cost, even no cost, approach to federal management. Another suggested approach would be a federal subsidy for wood-based energy enterprises willing to undertake thinning operations. In addition to these suggestions, the group stressed the need for solid, scientific sustainability guidelines and a need to equalize the incentives for all forms of biomass energy. For instance, thermal energy is not eligible for the same incentives as electric energy, even though it is a more energetically efficient process (one ton of wood will displace more fossil fuels if used to produce heat than if used to produce power).

October 18, 2007 - Conference Call - In this initial discussion, we brought together a group of academics and researchers interested in bioenergy production from forest materials. There was general agreement that an increase in active forest management, especially pre-commercial thinnings, is desirable in many, if not most, forests in this country from a standpoint of forest health. There seems to be two main obstacles to this thinning. The first is that we are facing a situation of domestic wood surplus and it difficult for a land manager to justify costly intermediate (pre-commercial) forest treatments when the demand for low-grade and small diameter material is essentially non-existent. The second barrier is a general wariness that the environmental community feels for both bioenergy and forest management. To address this concern, the consensus was that it is necessary to stress the co-benefits of using forest biomass for energy – not only is this a clean source of low carbon energy, but by adding value to forest thinnings it can make better forest management possible, including restoration forestry, pre-commercial thinning, wildlife habitat improvement, and much needed fire mitigation thinning across much of the western states. Uneven-aged silviculture, popular with private landowners and in areas managed for aesthetics and recreation, will also be feasible in more situations as the value of thinnings and low grade material is increased. Despite these positives, the group also came to a general consensus that we need to determine in greater detail the possible social, economic, and environmental impacts of using forest biomass for energy. In particular, we need to develop a model that allows us to determine the life-cycle climate change impacts of using forest biomass for energy (similar to the GREET model for agricultural crops). Finally, there was a discussion about scale and locations. In order to avoid negative impacts and overcome NIMBY feelings, it is key that both forest management and energy production sites are selected carefully and developed at a scale that is appropriate for both the local environment and the community.
