Background<\/strong><\/h1>\n

IEA Bioenergy is an international, collaborative research programme on Bioenergy. The primary goal of IEA Bioenergy Task 25 (“Greenhouse Gas Balances of Bioenergy Systems”) is to investigate all processes involved\u00a0 in the use of bioenergy systems, on a full fuel-cycle basis, with the aim of assessing overall greenhouse gas balances. Participating countries are Australia, Austria, Canada, Croatia, Finland, New Zealand, Sweden, United Kingdom, and the\u00a0 USA.<\/p>\n

The Task 25 workshop in Zagreb, Croatia, is part of a series of workshops within Task 25 taking place on a regular basis.<\/p>\n

Scope Of The Workshop, Events<\/strong><\/h1>\n

Demonstration of and hands-on experience with computer tools for greenhouse\u00a0 gas balances of bioenergy and carbon sequestration systems<\/b><\/h3>\n

Carbon\/greenhouse gas models for bioenergy, forestry, wood products, land-use and land-use change have been, or are being, developed by participating countries. 4 models were presented in detail, with time allowed for participants to use the models. The following models were presented at the workshop.<\/p>\n

CO2FIX<\/b><\/h3>\n

CO2FIX is a tool which quantifies the C stocks and fluxes in the forest (whole tree), soil organic matter compartment\u00a0 and the resulting wood products. It was originally designed for even aged monospecies stands in the Netherlands (Mohren and Klein Goldewijk 1990a), but has also been used for a wide variety of (mostly even aged) forest types from all over the world, including some selective logging systems (Nabuurs and Mohren 1993). The latter results have been used in the\u00a0 IPCC 1995 climate change assessment (Brown et al. 1996).<\/p>\n

Compared to the previous version of CO2FIX which was documented in Mohren and Klein Goldewijk (1990b), the present version<\/p>\n

    \n
  • is a user friendly windows-based version.<\/li>\n
  • is more precise in the allocation of harvested wood from thinnings and final fellings to wood product groups;<\/li>\n
  • has an option to choose for recycling;<\/li>\n
  • can directly sum the output of one forest type to larger areas;<\/li>\n
  • directly presents some of the output in a graph.<\/li>\n<\/ul>\n

    The current version is under further development in an EU funded project, “Carbon sequestration in afforestation and sustainable forest management: presentation of a general evaluation tool and generic case studies, CASFOR”.<\/p>\n

    GORCAM<\/b><\/h3>\n

    GORCAM is an Excel spreadsheet model that has been developed to calculate the net fluxes of carbon to and from the atmosphere associated with land use, land-use change, bioenergy and forestry projects. The model considers:<\/p>\n

      \n
    • changes of carbon (C) stored in vegetation, plant litter and soil,<\/li>\n
    • reduction of C emissions because biofuels replace fossil fuels,<\/li>\n
    • C storage in wood products,<\/li>\n
    • reduction of C emissions because wood products replace energy-intensive materials like steel or concrete,<\/li>\n
    • recycling or burning of waste-wood,<\/li>\n
    • auxiliary fossil fuels used for production of biofuels and wood products.<\/li>\n<\/ul>\n

      The model makes use of approximately 200 input parameters. For each scenario a new set of input parameters can be\u00a0 defined. They describe the management regime (harvest cycle, growth rate etc.), the land use before the project, and the way in which the biomass is used for carbon mitigation. Various biomass growth functions are availabe (including Richards function, possibility of precommercial thinning, and selective logging). The soil and litter\u00a0 carbon uptake or release can either be prescribed with exogenous assumptions or a dynamic calculation scheme can be used.<\/p>\n

      The model can be used to assess the future carbon balance for scenarios involving:<\/p>\n

        \n
      • a forest stand,<\/li>\n
      • a forest plantation system (normal forests), and<\/li>\n
      • a forest with a given age-class distribution (to deal with natural disturbances).<\/li>\n<\/ul>\n

        The model output is presented in diagrams with cumulative carbon sequestration in various carbon pools over time. The model also allows to view the individual carbon fluxes. In addition to the regular model\u00a0 output, another mode is available where future carbon fluxes are discounted to give a net present value.\u00a0 The higher the discount rate and the longer the time horizon, the more the results will differ from the basic output.<\/p>\n

        GORCAM is implemented in MS Excel 5.0, and makes use of Visual Basic Macro Programming. Each scenario can be saved as an Excel file, that still carries with it all the model features, including macros, diagrams and equations. GORCAM allows the performance of sensitivity analyses, whereby the impact on any model output of varying an input parameter can be assessed. In combination with Excel-compatible risk analysis tools such as Crystal Ball or @Risk, Monte Carlo Analyses can be carried out to determine the uncertainty of the model results. Probability distributions\u00a0 can be defined or chosen for all input parameters, and the model derives the probability distribution for any model output, for example, the carbon sequestration of a given project after 20 years.<\/p>\n

        ERGO<\/b><\/h3>\n

        The model ERGO has been developed for estimating energy and emissions budgets of bioenergy systems. ERGO was originally developed in the early 1990\u2019s with the primary aim of estimating energy and carbon budgets of bioenergy\u00a0 production from short rotation coppice tree systems. An important secondary objective was to provide a tool that could be used to compare different systems of bioenergy production directly, consistently and fairly. To achieve\u00a0 this ERGO needed to meet three important criteria, specifically the methods of energy and carbon budget estimation needed to be:<\/p>\n

          \n
        1. general: the model can be applied without restriction to the study of widely differing types of bioenergy\u00a0 production system, both annual and perennial, as well as woody and non-woody.<\/li>\n
        2. consistent: although the model is designed to be flexible, offering alternative methods of data input\u00a0 and calculation, at the same time the model imposes an essential discipline and structure on budget\u00a0 estimation, and ensures the use of common data sets where appropriate.<\/li>\n
        3. transparent: assumptions and calculations are described in detail in the input and output files\u00a0 of the model. Gaps in understanding or limitations in data can be readily identified.<\/li>\n<\/ol>\n

          ERGO\u2019s role in providing fundamental calculations of energy and emissions budgets of bioenergy systems may be viewed as underpinning GORCAM\u2019s policy-level projections of carbon sequestration potential and greenhouse gas balance impacts. Currently the estimation of greenhouse gas balances in ERGO is limited to the carbon balance,\u00a0 but extension of the model to represent other gases is straightforward.<\/p>\n

          GEMIS<\/b><\/h3>\n

          GEMIS (Global Emission Model for Integrated Systems) is a computerized life-cycle analysis model, LCA database,\u00a0 and cost-emission analysis system. It offers environmental and cost data for energy, material, and transport systems,\u00a0 including their life-cycles. The environmental data cover air emissions, greenhouse gases, liquid effluents, solid\u00a0 wastes, and land-use. The cost data concern investment, fixed annual, and variable cost, as well as externality\u00a0 factors for air emissions, and GHG. Further data are stored for “meta” information: comments and description,\u00a0 references, data quality indicators, location and statistical group.<\/p>\n

          GEMIS determines full life-cycle impacts of energy, transport, and material technologies. In addition to the totals, GEMIS also gives the individual contributions of all processes to a calculated result (breakdown ), and can determine results for selected system boundaries (e.g. a special location, in- or exclusion of material acquisition, crediting).<\/p>\n

          GEMIS evaluates deviations from multiple objectives (trade-offs), e.g., costs vs. emissions, or emissions vs. land use. It further calculates CO2 and SO2 equivalents, and the total resource use (cumulative energy and material\u00a0 demands). Because of the modular approach of the database (“unit” processes), the sensitivity of any\u00a0 result can be determined quickly by copying original data, and adjusting key parameters – within seconds, GEMIS then calculates the new results which can be compared immediately with the original data.<\/p>\n

          The software is public domain (i.e., free of charge), and updated regularly. More information can be found on the\u00a0 GEMIS websites [http:\/\/www.oeko.de\/service\/gemis (in\u00a0 German), http:\/\/www.oeko.de\/service\/temis and http:\/\/www.oeko.de\/service\/em].<\/p>\n

          Excursion<\/b><\/h3>\n

          A full-day study tour was undertaken to visit wood industry ITC in Varadin. The company has an advanced\u00a0 system of wood waste use, which includes a modern heating plant and mill for briquettes. The company is also known because of children toys and furniture production. Two other interesting visits were made – Veliki Tabor and Trakoscan castles, which are close to the study\u00a0 tour route.<\/p>\n
