Impact on the EU 2030 climate target of including LULUCF in the climate and energy policy Framework. Report prepared for Fern and IFOAM
The European Union (EU) has a target to reduce emissions by at least 40 per cent by 2030. This is an economy-wide target and therefore includes the Land Use, Land Use Change and Forestry (LULUCF) sector. The EU is currently consulting stakeholders on how to integrate LULUCF into the EUâs 2030 Climate and Energy Framework.
The LULUCF sector has several particularities and differs from energy, industrial processes, waste and agriculture (non-CO2) emissions in a number of ways.2 Adequate rules are therefore essential to reflect the changes in LULUCF and to assess progress towards targets. The most specific particularity is that the sector includes activities that cause emissions but also can lead to carbon being taken up and stored (e.g. through biomass accumulation), referred to in this report as a âremovalsâ, though the removal is not permanent. Currently LULUCF is a net sink in the EU, i.e. it removes more carbon than it releases, though this sink is projected to decline by 2030. Another particularity is that not all emissions and removals are directly human-induced. This is especially true for removals from forest management. One more general particularity is data uncertainty.
Average uncertainty ranges reported by Member States that are associated with estimates of the level of emissions and removals are relatively high (32 per cent) compared to emissions from fossil fuel combustion (1 per cent) for EU-15 countries
How to achieve reliable, transparent and independent monitoring of greenhouse gas emissions from land activities for policy support
On fair, effective and efficient REDD mechanism design
The issues surrounding 'Reduced Emissions from Deforestation and Forest Degradation' (REDD) have become a major component of continuing negotiations under the United Nations Framework Convention on Climate Change (UNFCCC). This paper aims to address two key requirements of any potential REDD mechanism: first, the generation of measurable, reportable and verifiable (MRV) REDD credits; and secondly, the sustainable and efficient provision of emission reductions under a robust financing regime
Setting priorities for land management to mitigate climate change
<p>Abstract</p> <p>Background</p> <p>No consensus has been reached how to measure the effectiveness of climate change mitigation in the land-use sector and how to prioritize land use accordingly. We used the long-term cumulative and average sectorial C stocks in biomass, soil and products, C stock changes, the substitution of fossil energy and of energy-intensive products, and net present value (NPV) as evaluation criteria for the effectiveness of a hectare of productive land to mitigate climate change and produce economic returns. We evaluated land management options using real-life data of Thuringia, a region representative for central-western European conditions, and input from life cycle assessment, with a carbon-tracking model. We focused on solid biomass use for energy production.</p> <p>Results</p> <p>In forestry, the traditional timber production was most economically viable and most climate-friendly due to an assumed recycling rate of 80% of wood products for bioenergy. Intensification towards "pure bioenergy production" would reduce the average sectorial C stocks and the C substitution and would turn NPV negative. In the forest conservation (non-use) option, the sectorial C stocks increased by 52% against timber production, which was not compensated by foregone wood products and C substitution. Among the cropland options wheat for food with straw use for energy, whole cereals for energy, and short rotation coppice for bioenergy the latter was most climate-friendly. However, specific subsidies or incentives for perennials would be needed to favour this option.</p> <p>Conclusions</p> <p>When using the harvested products as materials prior to energy use there is no climate argument to support intensification by switching from sawn-wood timber production towards energy-wood in forestry systems. A legal framework would be needed to ensure that harvested products are first used for raw materials prior to energy use. Only an effective recycling of biomaterials frees land for long-term sustained C sequestration by conservation. Reuse cascades avoid additional emissions from shifting production or intensification.</p
An assessment of monitoring requirements and costs of 'Reduced Emissions from Deforestation and Degradation'
<p>Abstract</p> <p>Background</p> <p>Negotiations on a future climate policy framework addressing Reduced Emissions from Deforestation and Degradation (REDD) are ongoing. Regardless of how such a framework will be designed, many technical solutions of estimating forest cover and forest carbon stock change exist to support policy in monitoring and accounting. These technologies typically combine remotely sensed data with ground-based inventories. In this article we assess the costs of monitoring REDD based on available technologies and requirements associated with key elements of REDD policy.</p> <p>Results</p> <p>We find that the design of a REDD policy framework (and specifically its rules) can have a significant impact on monitoring costs. Costs may vary from 0.5 to 550 US$ per square kilometre depending on the required precision of carbon stock and area change detection. Moreover, they follow economies of scale, i.e. single country or project solutions will face relatively higher monitoring costs.</p> <p>Conclusion</p> <p>Although monitoring costs are relatively small compared to other cost items within a REDD system, they should be shared not only among countries but also among sectors, because an integrated monitoring system would have multiple benefits for non-REDD management. Overcoming initialization costs and unequal access to monitoring technologies is crucial for implementation of an integrated monitoring system, and demands for international cooperation.</p
Dynamics of the land use, land use change, and forestry sink in the European Union: the impacts of energy and climate targets for 2030
Twenty-three unsolved problems in hydrology (UPH) â a community perspective
This paper is the outcome of a community initiative to identify major unsolved scientific problems in hydrology motivated by a need for stronger harmonisation of research efforts. The procedure involved a public consultation through on-line media, followed by two workshops through which a large number of potential science questions were collated, prioritised, and synthesised. In spite of the diversity of the participants (230 scientists in total), the process revealed much about community priorities and the state of our science: a preference for continuity in research questions rather than radical departures or redirections from past and current work. Questions remain focussed on process-based understanding of hydrological variability and causality at all space and time scales.
Increased attention to environmental change drives a new emphasis on understanding how change propagates across interfaces within the hydrological system and across disciplinary boundaries. In particular, the expansion of the human footprint raises a new set of questions related to human interactions with nature and water cycle feedbacks in the context of complex water management problems. We hope that this reflection and synthesis of the 23 unsolved problems in hydrology will help guide research efforts for some years to come
