How does bioenergy compare with other land-based renewable energy sources globally?
The potential power generation from land-based bioenergy is predicted globally using a computer model. Simultaneous consideration of land use, cost and carbon restrictions enables practical evaluation of net power output. Comparisons are made with wind and solar power, and a sensitivity analysis is used to explore the effects of different policy assumptions. Biomass is shown to offer only moderate power-generating potential, and would satisfy less than half of current demand even if all suitable existing arable land were used to grow bioenergy crops. However, bioenergy can be cheap to generate given current economics, and is able to remove atmospheric carbon in some cases if coupled with carbon capture and storage. Wind turbines are able to provide more power globally, but photovoltaic solar panels are the only source considered with the potential to satisfy existing demand. Since land-based bioenergy is also restricted by the need to grow food for an expanding population, and technological developments are likely to greatly increase the viability of other renewable sources, the role of land-based bioenergy appears relatively limited and short-term
Barriers to European bioenergy expansion
The European Commission has set challenging targets for renewable energy expansion in Europe as part of its strategy to limit greenhouse gas emissions. Expansion of existing bioenergy capacity has a key role to play in ensuring these targets are met. However, significant technical and non-technical barriers to deployment of biomass technologies remain throughout Europe, the latter often being more difficult to address. Non-technical barriers are fundamental obstacles to biomass development. They represent limits or boundaries to the extent of deployment, often related to institutional frameworks, perceptions, socio-economic issues or engagement of and interfaces with related technology sectors. This paper presents an analysis, characterization and prioritization of the current non-technical barriers to thermo-chemical bioenergy expansion in Europe. Policy, economics and stakeholder understanding are strategically important if bioenergy potential is to be realized. Detailed policy evaluation with case study history from 4 European member states shows continuity of policy instruments is critical and specific support instruments work better than more general mechanisms. Improved stakeholder understanding (with the general public as a relevant stakeholder group) is key to increasing the acceptability of bioenergy. This requires different parallel strategies for different sectors/target groups. Promotional campaigns, dissemination of information to key multipliers, provision of independent factual information to the public, appropriate frameworks for handling approvals for new plants, forums for stakeholder interaction and certification schemes all have a role to play in improving bioenergy acceptability
Ex Ante Impact Assessment of Policies Affecting Land Use, Part B: Application of the Analytical Framework
The use of science-based tools for impact assessment has increasingly gained focus in addressing the complexity of interactions between environment, society, and economy. For integrated assessment of policies affecting land use, an analytical framework was developed. The aim of our work was to apply the analytical framework for specific scenario cases and in combination with quantitative and qualitative application methods. The analytical framework was tested for two cases involving the ex ante impact assessment of: (1) a European Common Agricultural Policy (CAP) financial reform scenario employing a modeling approach and combined with a comprehensive indicator analysis and valuation; and (2) a regional bioenergy policy scenario, employing a fully participatory approach. The results showed that European land use in general is less sensitive to changes in the Common Agricultural Policy, but in the context of regions there can be significant impacts on the functions of land use. In general, the implementation of the analytical framework for impact assessment proved to be doable with both methods, i.e., with the quantitative modeling and with the qualitative participatory approach. A key advantage of using the system of linked quantitative models is that it makes possible the simultaneous consideration of all relevant sectors of the economy without abstaining from a great level of detail for sectors of particular interest. Other advantages lie in the incontestable character of the results. Based on neutral, existing data with a fixed set of settings and regions, an absolute comparability and reproducibility throughout Europe can be maintained. Analyzing the pros and cons of both approaches showed that they could be used complementarily rather than be seen as competing alternatives
Mutual Dependence between Sustainable Energy- and Sustainable Agriculture Policies-from the Global and European Perspective
Agriculture is one of the economic sectors to which the EU commitment to reduce emissions of greenhouse gases applies. Like any other economic sector, agriculture produces greenhouse gases and is a major source of the non- CO2 greenhouse gases methane and nitrous oxide. It is also the strong relationship between the sustainable agriculture sector and the renewable energy development possibilities. The sustainable agriculture can be seen as a source of renewable energy
A strategic niche management approach for shaping bio-based economy in Europe
The goal of this paper is to investigate the transition towards a bio-based economy as part of a broader sustainable transition in Europe. To analyse the challenges and opportunities associated with the bio-based economy, we applied the Strategic Niche Management approach to investigate the drivers that boost the emergence of the bio-based economy, the factors hindering it, as well as institutional changes which are at the base of the socio-technological transition. Although considered as just one piece of the sustainability puzzle, the bio-based economy behaves as a socio-technical system on its own, providing valuable hints on systemic transitions
Circular economy for climate neutrality: Setting the priorities for the EU. CEPS Policy Brief No 2019/04, 22 November 2019
The previous Commission policy on resources management was part of the priority for jobs and growth and
economic competitiveness. The circular economy will be no less important for the new political priority of
climate neutrality; it will become one of the indispensable elements for meeting the EU’s ambitions. EU
climate policy and the circular economy are by and large complementary and mutually reinforcing. The
circular economy is more than just another ‘product standards’ policy.
In order for this to happen,
• there is a need for a framework that is able to systematically address trade-offs, such as between the
circular and the bioeconomy, but also between material efficiency and energy use, as well as
• a mechanism to steer and monitor progress, touching upon the question of whether and if so, how to
increase ambition and develop tools to monitor progress, for example via targets, and
• the new Commission will need to develop and then scale up successful products and processes to create
opportunities for new value chains while addressing risks, such as dependency on raw materials.
Circular economy products for the foreseeable future will require both technology push and market pull
policies. Both the circular economy and low-carbon economy will require new and often yet unknown
business models. This will also require new methods of regulation.
The principal challenge will be to create ‘lead markets’ for the circular economy in combination with lowcarbon
products. Many ideas for this exist. They include, for example, ‘carbon contracts for difference’,
carbon budgets for projects, consumption charges, taxes and tax exemptions, sustainable finance, product
standards and public procurement. Ideas now need to be tested to see whether they could work in practice.
Finally, the EU circular economy will need to be underpinned by a robust and transparent carbon accounting
system. If effective, such as system can at the same time act as a catalyst for investment in the circular
economy and low-carbon products and processes
Applied General Equilibrium Analysis of Renewable Energy Policies
In this paper we develop an applied general equilibrium framework for assessing socio-economic impacts of alternative renewable energy policies and apply it to the bioenergy sector. The policy scenarios are assessed in a comparative static analysis. The numerical simulation results allow us to assess and compare welfare and distributional impacts of alternative renewable energy policies. Our empirical findings suggest that the bioenergy sector in Poland would benefit most from an indirect tax reduction. According to our simulation results, reducing the fossil energy sectors’ subsidies would be the second best policy option.Applied General Equilibrium, CGE, Renewable Energy, Bioenergy
CGIAR Research Program on Forests, Trees and Agroforestry - Plan of Work and Budget 2020
There were no significant changes in 2019 to FTA’s theory of change1. FTA plans all its work on the basis of its operational priorities. These, in turn, focusresearch towards major development demands and knowledge gaps, orienting FTA towards the implementation of the SDGs and other global commitments. Three operational priorities were added in 2020 (see list in Appendix 1) to better delineate pre-existing research areas addressing development bottlenecks needing dedicated investment and visibility: smallholder tree-crop commodities, tree seeds and seedlings delivery systems, and foresight. FTA organized in 2019, at the request of its ISC, a joint ISC-FTA workshop on impact assessment methods for the program. Based on the outcomes of this workshop FTA will, inter alia, revisit in 2020 its impact pathways and end of programme outcomes, and if need be, corresponding adjustments to the ToC of FTA and/or of its FPs will be made

The adoption of clean energy in Boston’s buildings and transportation systems will produce sweeping
changes in the quantity and composition of the city’s demand for fuel and electricity. The demand for
electricity is expected to increase by 2050, while the demand for petroleum-based liquid fuels and
natural gas within the city is projected to decline significantly. The city must meet future energy demand
with clean energy sources in order to meet its carbon mitigation targets. That clean energy must be
procured in a way that supports the City’s goals for economic development, social equity, environmental
sustainability, and overall quality of life. This chapter examines the strategies to accomplish these goals.
Improved energy efficiency, district energy, and in-boundary generation of clean energy (rooftop PV)
will reduce net electric power and natural gas demand substantially, but these measures will not
eliminate the need for electricity and gas (or its replacement fuel) delivered into Boston. Broadly
speaking, to achieve carbon neutrality by 2050, the city must therefore (1) reduce its use of fossil fuels
to heat and cool buildings through cost-effective energy efficiency measures and electrification of
building thermal services where feasible; and (2) over time, increase the amount of carbon-free
electricity delivered to the city. Reducing energy demand though cost effective energy conservation
measures will be necessary to reduce the challenges associated with expanding the electricity delivery
system and sustainably sourcing renewable fuels.Published versio
