Harmonized Methods for Assessing Carbon Sequestration in European Forests

The MASCAREF (Study under EEC 2152/2003 Forest Focus regulation on developing harmonized methods for assessing carbon sequestration in European forests) project was conducted by a consortium of 10 European institutions coordinated by IFER ¿ Institute of Forest Ecosystem Research, Czech Republic. The overall objective of this project was to contribute to the development of a monitoring scheme for carbon sequestration in forests of the European Union (EU). Specifically, the project aimed at i) strengthening and harmonizing the existing national systems to better meet the requirements of international monitoring and reporting of greenhouse-gas (GHG) emissions and sinks and ii) improving the comparability, transparency and accuracy of the GHG inventory reports of the Land use, land-use change and forestry (LULUCF) sector of the EU Member States, as implemented in the EC Monitoring Mechanism. This project represents a step towards addressing the challenges of GHG inventories and the reporting under the United Nations Framework Convention on Climate Change (UNFCCC) and its Kyoto protocol related to forest land and forest activities. Reflecting the heterogeneity in land use, natural conditions and monitoring data availability, there is a wide variety in greenhouse gas reporting practices within the European Community, which becomes clearly apparent from an overview of the current GHG reporting practices prepared by MASCAREF. The particular tasks of the project were based on available data from regional, national and EU-wide projects and relevant activities that took place over the last decade. The project elaboration was conducted within several major tasks, followed by selected regional case-studies. Firstly, the currently available data and methodological approaches to estimate carbon stock and carbon stock change for emission inventories were analyzed. Secondly, the project conducted an analysis of ICP Forests health monitoring and Forest Focus programs. Similarly, it assessed the potential of utilizing data from the European National Forest Inventories for the purpose of emission inventory under UNFCCC and the Kyoto protocol. Related to this, the JRC AFOLUDATA website on biomass functions and conversion/expansion factors http://afoludata.jrc.ec.europa.eu/index.php/public_area/home) was complemented by adding new factors from the European member states. Also, the methodologies to aggregate the forest carbon stock data based on the National Forest Inventory plots to a 10x10 km grid were explored. Finally, several of the above tasks were elaborated and/or applied in case studies in the selected regions of Europe. The MASCAREF project fulfilled its main objectives and its results should facilitate a further development of monitoring schemes for carbon stock change assessment in forests of the European member states, hopefully leading to an improved GHG reportingJRC.DDG.H.2-Climate chang

Review of existing information on the interrelations between soil and climate change. (ClimSoil). Final report

Carbon stock in EU soils – The soil carbon stocks in the EU27 are around 75 billion tonnes of carbon (C); of this stock around 50% is located in Sweden, Finland and the United Kingdom (because of the vast area of peatlands in these countries) and approximately 20% is in peatlands, mainly in countries in the northern part of Europe. The rest is in mineral soils, again the higher amount being in northern Europe. 2. Soils sink or source for CO2 in the EU – Both uptake of carbon dioxide (CO2) through photosynthesis and plant growth and loss of CO2 through decomposition of organic matter from terrestrial ecosystems are significant fluxes in Europe. Yet, the net terrestrial carbon fluxes are typically 5-10 times smaller relative to the emissions from use of fossil fuel of 4000 Mt CO2 per year. 3. Peat and organic soils - The largest emissions of CO2 from soils are resulting from land use change and especially drainage of organic soils and amount to 20-40 tonnes of CO2 per hectare per year. The most effective option to manage soil carbon in order to mitigate climate change is to preserve existing stocks in soils, and especially the large stocks in peat and other soils with a high content of organic matter. 4. Land use and soil carbon – Land use and land use change significantly affects soil carbon stocks. On average, soils in Europe are most likely to be accumulating carbon on a net basis with a sink for carbon in soils under grassland and forest (from 0 - 100 billion tonnes of carbon per year) and a smaller source for carbon from soils under arable land (from 10 - 40 billion tonnes of carbon per year). Soil carbon losses occur when grasslands, managed forest lands or native ecosystems are converted to croplands and vice versa carbon stocks increase, albeit it slower, following conversion of cropland. 5. Soil management and soil carbon – Soil management has a large impact on soil carbon. Measures directed towards effective management of soil carbon are available and identified, and many of these are feasible and relatively inexpensive to implement. Management for lower nitrogen (N) emissions and lower C emissions is a useful approach to prevent trade off and swapping of emissions between the greenhouse gases CO2, methane (CH4) and nitrous oxide (N2O). 6. Carbon sequestration – Even though effective in reducing or slowing the build up of CO2 in the atmosphere, soil carbon sequestration is surely no ‘golden bullet’ alone to fight climate change due to the limited magnitude of its effect and its potential reversibility; it could, nevertheless, play an important role in climate mitigation alongside other measures, especially because of its immediate availability and relative low cost for 'buying' us time. 7. Effects of climate change on soil carbon pools – Climate change is expected to have an impact on soil carbon in the longer term, but far less an impact than does land use change, land use and land management. We have not found strong and clear evidence for either overall and combined positive of negative impact of climate change (atmospheric CO2, temperature, precipitation) on soil carbon stocks. Due to the relatively large gross exchange of CO2 between atmosphere and soils and the significant stocks of carbon in soils, relatively small changes in these large and opposing fluxes of CO2, i.e. as result of land use (change), land management and climate change, may have significant impact on our climate and on soil quality. 8. Monitoring systems for changes in soil carbon – Currently, monitoring and knowledge on land use and land use change in EU27 is inadequate for accurate calculation of changes in soil carbon contents. Systematic and harmonized monitoring across EU27 and across relevant land uses would allow for adequate representation of changes in soil carbon in reporting emissions from soils and sequestration in soils to the UNFCCC. 9. EU policies and soil carbon – Environmental requirements under the Cross Compliance requirement of CAP is an instrument that may be used to maintain SOC. Neither measures under UNFCCC nor those mentioned in the proposed Soil Framework Directive are expected to adversely impact soil C. EU policy on renewable energy is not necessarily a guarantee for appropriate (soil) carbon management

Assessing Investment in Future Landsat Instruments: The Example of Forest Carbon Offsets

We extend the theory of quality-adjusted expenditure indices to estimate benefits from public investment. In particular, we model the selection of new instruments (in the form of remote-sensing devices) to enhance the longest-operating U.S. satellite-based land-observing program, Landsat. We then apply the model to the use of Landsat in measuring global forest carbon sequestration. Improving measurement of the role of forests in storing carbon has become a prominent concern in climate policy. By characterizing the value of Landsat data in forest measurement, the expenditure function allows us to help inform public investment decisions in the satellite system. The expenditure function also makes explicit the sensitivity of the selection of instruments for the satellites to the value of Landsat information, thus linking instrument choice explicitly to policy design.value of information, satellite data, forests, carbon, sequestration, Landsat

Trading schemes for greenhouse gas emissions from European agriculture: A comparative analysis based on different implementation options

A rational negotiation strategy for coming multilateral negotiations regarding climate change requires knowledge about possible social, economic and environmental effects of policy instruments for the abatement of greenhouse gas emissions. With this purpose, an agricultural sector model is expanded to cover greenhouse gas emissions from agricultural sources in Europe and policy instruments for their reduction. This modelling approach concentrates on the application of a permit trade scheme for emission abatement within the Kyoto Protocol ‘first commitment’ baseline. The effects derived of three alternative schemes are described in detail: the EU ‘burden sharing’ agreement option defined as regional emission standards, emission trading between regions inside each Member State, and finally, emission trading between all European regions. The analysis shows the importance of selecting an adequate combination of instruments of emission abatement for the design of efficient emission reduction policies.Kyoto Protocol, agricultural policy, economic modelling, tradable emission permits
