Lamb WF, Wiedmann T, Pongratz J, et al., 2021, A review of trends and drivers of greenhouse gas emissions by sector from 1990 to 2018, Environmental Research Letters, Vol: 16, Pages: 1-31, ISSN: 1748-9326
Global greenhouse gas (GHG) emissions can be traced to five economic sectors: energy, industry, buildings, transport and AFOLU (agriculture, forestry and other land uses). In this topical review, we synthesise the literature to explain recent trends in global and regional emissions in each of these sectors. To contextualise our review, we present estimates of GHG emissions trends by sector from 1990 to 2018, describing the major sources of emissions growth, stability and decline across ten global regions. Overall, the literature and data emphasise that progress towards reducing GHG emissions has been limited. The prominent global pattern is a continuation of underlying drivers with few signs of emerging limits to demand, nor of a deep shift towards the delivery of low and zero carbon services across sectors. We observe a moderate decarbonisation of energy systems in Europe and North America, driven by fuel switching and the increasing penetration of renewables. By contrast, in rapidly industrialising regions, fossil-based energy systems have continuously expanded, only very recently slowing down in their growth. Strong demand for materials, floor area, energy services and travel have driven emissions growth in the industry, buildings and transport sectors, particularly in Eastern Asia, Southern Asia and South-East Asia. An expansion of agriculture into carbon-dense tropical forest areas has driven recent increases in AFOLU emissions in Latin America, South-East Asia and Africa. Identifying, understanding, and tackling the most persistent and climate-damaging trends across sectors is a fundamental concern for research and policy as humanity treads deeper into the Anthropocene.

Di Lucia L, Peterson S, Sevigné-Itoiz E, et al., 2020, Using participatory system dynamics modelling to quantify indirect land use changes of biofuel projects, Journal of Land Use Science, Vol: 16, Pages: 111-128, ISSN: 1747-423X
The use of biomass to produce biofuels can lead to both direct and indirect Land Use Change (LUC). While the causes underlying LUCs are complex their quantification is a scientific challenge that hinders decision-making. Here we demonstrate the application of participatory modelling in combination with System Dynamics techniques to the analysis of the land-change dynamics associated with biofuel supply chains. The ambition is to provide decision-makers with useful and credible knowledge of direct and indirect LUCs. We illustrate the application of the approach by applying it to a real‐world project for the production of advanced biofuels in Sardinia (Italy). The results show that the land use displacements vary in intensity and persistence depending on the crop management regime applied and the future development of the market of sheep cheese. The results were considered credible by actors with direct knowledge of the ‘real’ system and useful by decision makers .
Halttunen K, Staffell I, Slade R, et al., 2020, Global assessment of the merit-order effect and revenue cannibalisation for variable renewable energy, Publisher: Elsevier
The rapid growth of wind and solar power has been a major driver for decarbonisation worldwide. They tend to reduce wholesale electricity prices, both the time-weighted average (the merit‑order effect) and their own output-weighted average (price cannibalisation). Whilst these effects have been widely observed, most previous studies focus on single countries. Here, we compare 37 electricity markets across Europe, North America, Australia and Japan and explore variations between them.Merit-order and cannibalisation effects are observed in nearly all countries studied. However, only in Germany, Spain, Poland, Portugal, Denmark and California can renewable output explain more than 10% of variation in wholesale electricity prices. The global average merit‑order effect is €0.68±€0.54 /MWh per percentage point increase in variable renewable energy penetration, and this falls with higher penetration. Revenues captured by wind farms decrease by 0.23% (€0.16 /MWh) for each percentage point increase of wind penetration and by 1.94% (€0.90 /MWh) for solar PV.
Gibson MF, Rao ND, Slade RB, et al., 2020, The role of energy in mitigating grain storage losses in India and the impact for nutrition, Resources, Conservation and Recycling, Vol: 163, ISSN: 0921-3449
Globally, India's population is amongst the most severely impacted by nutrient deficiency, yet millions of tonnes of food are lost along the supply chain before reaching consumers. Across food groups, grains represent the largest share of daily calories and overall losses by mass in India. This study quantifies energy input to minimise storage losses across India, responsible for up to a quarter of grain losses. In doing so, we explore links between three Sustainable Development Goals-SDG2, SDG7, and SDG12-, and provide insight for development of joined up agriculture and health policy in the country. Focusing on rice, wheat, maize, bajra, and sorghum, we quantify one route to reduce losses in supply chains, by modelling the energy input to maintain favourable climatic conditions in modern silo storage. We quantify key nutrients (calories, protein, zinc, iron, vitamin A) contained within these losses, and calculate roughly how much deficiency in these dietary components could be reduced if grain losses were eliminated. Our modelling indicates that maize has the highest energy input intensity for storage, at 110 (18) kWh per tonne of grain (kWh/t), and wheat the lowest, at 72 (14) kWh/t. This energy cost represents 8%-16% of the energy input required in grain production. We estimate if grain losses across the supply chain were saved and targeted to India's nutritionally deficient population, average protein deficiency could reduce by 46±4%, calorie by 27±2%, zinc by 26±2% and iron by 11±1%.
Di Lucia L, Sevigne-Itoiz E, Peterson S, et al., 2019, Project level assessment of indirect land use changes arising from biofuel production, Global Change Biology Bioenergy, Vol: 11, Pages: 1361-1375, ISSN: 1757-1693
The use of land resources has a strong influence on the sustainability of biofuel production. An assessment of both direct and indirect changes in land use is necessary if an accurate assessment of sustainability is to be made. An increasing number of studies have developed approaches to estimate the Indirect Land Use Change (ILUC) impacts of biofuels at global, national or regional level, but assessing ILUC remains a challenging task and estimates vary widely. In this study, we suggest that a socially motivated, project level approach can provide robust insight into the conditions affecting land use change dynamics. We developed a causal‐descriptive approach named ILUC Project ASsessment Tool (ILUC PAST) for project level assessment of ILUC. It uses a tiered multitool analysis—from local to global—combined with extensive stakeholder engagement. A real‐world project for the production of cellulosic ethanol in Sardinia (Italy) was used to evaluate the tool and benchmark the results against two alternatives for project level assessment: the ‘Low Indirect Impact Biofuel’ methodology and the ‘iLUC Club’ method. The results of the case study of advanced biofuels suggest that the quantitative estimates of ILUC combined with the in‐depth understanding of the cause‐and‐effect dynamics provided by ILUC PAST are sufficiently credible, salient and legitimate to support project level and local decision‐making.
Albanito F, Hastings A, Fitton N, et al., 2019, Mitigation potential and environmental impact of centralized versus distributed BECCS with domestic biomass production in Great Britain, Global Change Biology Bioenergy, Vol: 11, Pages: 1234-1252, ISSN: 1757-1693
New contingency policy plans are expected to be published by the United Kingdom government to set out urgent actions, such as carbon capture and storage, greenhouse gas removal and the use of sustainable bioenergy to meet the greenhouse gas reduction targets of the 4th and 5th Carbon Budgets. In this study, we identify two plausible bioenergy production pathways for bioenergy with carbon capture and storage (BECCS) based on centralized and distributed energy systems to show what BECCS could look like if deployed by 2050 in Great Britain. The extent of agricultural land available to sustainably produce biomass feedstock in the centralized and distributed energy systems is about 0.39 and 0.5 Mha, providing approximately 5.7 and 7.3 MtDM/year of biomass respectively. If this land‐use change occurred, bioenergy crops would contribute to reduced agricultural soil GHG emission by 9 and 11 urn:x-wiley:17571693:media:gcbb12630:gcbb12630-math-0001/year in the centralized and distributed energy systems respectively. In addition, bioenergy crops can contribute to reduce agricultural soil ammonia emissions and water pollution from soil nitrate leaching, and to increase soil organic carbon stocks. The technical mitigation potentials from BECCS lead to projected CO2 reductions of approximately 18 and 23 urn:x-wiley:17571693:media:gcbb12630:gcbb12630-math-0002/year from the centralized and distributed energy systems respectively. This suggests that the domestic supply of sustainable biomass would not allow the emission reduction target of 50 urn:x-wiley:17571693:media:gcbb12630:gcbb12630-math-0003/year from BECCS to be met. To meet that target, it would be necessary to produce solid biomass from forest systems on 0.59 or 0.49 Mha, or alternatively to import 8 or 6.6 MtDM/year of biomass for the centralized and distributed energy system respectively. The spatially explicit results of this study can serve to identify the regional differences in the potential capture of CO2 from BECC

Pearce P, Slade R, 2018, Feed-in tariffs for solar microgeneration: Policy evaluation and capacity projections using a realistic agent-based model, Energy Policy, Vol: 116, Pages: 95-111, ISSN: 0301-4215
Since 2010, over 700,000 small-scale solar photovoltaic (PV) systems have been installed by households in Great Britain and registered under the feed-in tariff (FiT) scheme. This paper introduces a new agent-based model which simulates this adoption by considering decision-making of individual households based on household income, social network, total capital cost of the PV system, and the payback period of the investment, where the final factor takes into account the economic effect of FiTs. After calibration using Approximate Bayesian Computation, the model successfully simulates observed cumulative and average capacity installed over the period 2010–2016 using historically accurate FiTs; setting different tariffs allows investigation of alternative policy scenarios. Model results show that using simple cost control measures, more installation by October 2016 could have been achieved at lower subsidy cost. The total cost of supporting capacity installed during the period 2010–2016, totalling 2.4 GW, is predicted to be £14 billion, and costs to consumers significantly exceed predictions. The model is further used to project capacity installed up to 2022 for several PV cost, electricity price, and FiT policy scenarios, showing that current tariffs are too low to significantly impact adoption, and falling PV costs are the most important driver of installation.
Slade RB, Di Lucia L, adams P, 2018, How Policy Makers Learnedto Start Worrying and Fell Out of LoveWith Bioenergy, Greenhouse gas balances of bioenergy systems, Editors: Thornley, Adams, Publisher: Academic Press (Elsevier)
Bioenergy has come to be given a prominent role in national energy strategies in more than 60 countries around the world. The impetus for these policies draws on a range of motivations: improving energy security, diversifying agricultural production stimulating rural development, job creation, and reducing greenhouse gas (GHG) emissions. Arguably GHG reductions was never the main driver for bioenergy policy, yet controversy over the extent, timing and duration of carbon savings threatens to derail policy initiatives to drive up deployment. This paper analyses current controversies around bioenergy in the context of historic developments in the United States, Brazil or European Union. It addresses two key questions: “how did we end up in this policy mess?” And, “how do we get out of it?” Policy makers have faced three broad challenges to whether policies introduced to support bioenergy can genuinely contribute to GHG mitigation. The first is that carbon accounting frameworks misrepresent the carbon saving benefits of bioenergy, potentially leading policy makers to support policies that have unintended and undesirable consequences. The second is that increasing biomass production on agricultural land can directly, or indirectly, lead to increasing carbon emissions. The third challenge is that increased use of forest biomass does nothing to reduce emissions in the short term but can only reduce carbon emissions in the distant future. We examine the evidence around each of these challenges and critically evaluate the policy responses. We argue that the greatest risk lies in political loss of confidence and institutional paralysis. Whereas the greatest opportunity lies in the co-evolution of bioenergy production and governance systems, drawing on the collective judgment of stakeholders involved in experiential, interactive and deliberative decision making processes.

Dale VH, Kline KL, Parish ES, et al., 2017, Status and prospects for renewable energy using wood pellets from the southeastern United States, GCB Bioenergy, Vol: 9, Pages: 1296-1305, ISSN: 1757-1693
Global Change Biology Bioenergy Published by John Wiley & Sons Ltd. The ongoing debate about costs and benefits of wood-pellet based bioenergy production in the southeastern United States (SE USA) requires an understanding of the science and context influencing market decisions associated with its sustainability. Production of pellets has garnered much attention as US exports have grown from negligible amounts in the early 2000s to 4.6 million metric tonnes in 2015. Currently, 98% of these pellet exports are shipped to Europe to displace coal in power plants. We ask, ‘How is the production of wood pellets in the SE USA affecting forest systems and the ecosystem services they provide?’ To address this question, we review current forest conditions and the status of the wood products industry, how pellet production affects ecosystem services and biodiversity, and what methods are in place to monitor changes and protect vulnerable systems. Scientific studies provide evidence that wood pellets in the SE USA are a fraction of total forestry operations and can be produced while maintaining or improving forest ecosystem services. Ecosystem services are protected by the requirement to utilize loggers trained to apply scientifically based best management practices in planning and implementing harvest for the export market. Bioenergy markets supplement incomes to private rural landholders and provide an incentive for forest management practices that simultaneously benefit water quality and wildlife and reduce risk of fire and insect outbreaks. Bioenergy also increases the value of forest land to landowners, thereby decreasing likelihood of conversion to nonforest uses. Monitoring and evaluation are essential to verify that regulations and good practices are achieving goals and to enable timely responses if problems arise. Conducting rigorous research to understand how conditions change in response to management choices requires baseline data, monitoring, and

Aviation is responsible for an increasing share of anthropogenic CO2 emissions.Decarbonisation to 2050 is expected to rely on renewable jet fuel (RJF) derived frombiomass, but this represents a radical departure from the existing regime of petroleumbasedfuels. Increased market deployment will require significant cost reductions, alongsideadaptation of existing supply chains and infrastructure.This article maps development and manufacturing efforts for six RJF production pathwaysexpected to reach commercialisation in the next 5-10 years. A Rapid Evidence Assessmentwas conducted to evaluate the technological and commercial maturity of each pathway andprogress towards international certification, using the Commercial Aviation Alternative FuelsInitiative’s Fuel Readiness Level (FRL) framework. Planned and operational facilities havebeen catalogued alongside partnerships with the aviation industry. Policy and economicfactors likely to affect future development and deployment are considered.Hydroprocessed Esters and Fatty Acids (FRL 9) is the most developed pathway. It is ASTMcertified, has fuelled the majority of RJF flights to date, and is produced at threecommercial-scale facilities. Fischer-Tropsch derived fuels are moving towards the start-up offirst commercial facilities (FRL 7-8), although widespread deployment seems unlikely undercurrent market conditions. The Direct Sugars to Hydrocarbons conversion pathway (FRL 5-7)is being championed by Amyris and Total in Brazil, but has yet to be demonstrated at scale.Other pathways are in the demonstration and pilot phases (FRL 4-6).Despite growing interest in RJF, demand and production volumes remain negligible.Development of supportive policy is likely to be critical to future deployment.

As global population increases, the connections between food, water, energy and the environment at global and regional scales become ever more important. The complexity and inter-connectedness of these relationships challenge policymakers, scientists, businesses andcitizens to find acceptable ways forward, but there are no easy solutions. This is the ‘nexus’.Citizen science can provide a powerful mechanism to help tackle these environmental and social challenges. In this thinkpiece we draw on the experiences of citizen science practitioners, particularly from the environmental sector. Citizens are the guardians of their local environment and, arguably, often know the places where they live better than regulators, policymakers and industry. Local citizens will usuallybe the first to notice changes in their immediate environment, whether instant changes (such as a pollution spill) or gradual (such as species decline). Citizen science can generate and broaden out the kinds of data that are considered in the investigation of environmental issues.Benefits of participating in citizen science include raised awareness, increased education, greater involvement, more participatory democracy, and increased ownership of solutions. Participation may also bring wider social, health and wellbeing benefits. Professionalscientists in turn benefit from the data submitted by volunteers, the value of which can be estimated at many millions of pounds per year.Some of the generic challenges to successful citizen science will be heightened in the context of understanding and dealing with nexus issues. These include extending citizen science (which is normally conducted at local level) to regional and global scales, optimising thecollection of data through better coordination between practitioners, empowering citizens and businesses to take more control of the conception and design of citizen science activities, and understanding the motivations, attitudes and practices of all
McLaughlin O, Mawhood B, Jamieson C, et al., 2015, Rice straw for bioenergy: the effectiveness of policymaking and implementation in Asia, 24th European Biomass Conference and Exhibition, Publisher: EUBCE
Globally, rice straw is the third largest agricultural residue, behind sugarcane bagasse and maize straw.Approximately one billion tonnes of rice straw are produced annually, but only a small proportion of this is used. Theprimary management strategies of rice straw farmers are burning in the fields and mulching. Burning producesharmful carcinogenic and greenhouse gas emissions and mulching releases high levels of methane which have aneven greater greenhouse gas effect than the CO2 released from burning. In comparison, using rice straw for bioenergyhas considerable advantages.This study examines the barriers to the use of rice straw for bioenergy, and the effectiveness of the existing policymechanisms in seven major rice producing nations: Bangladesh, China, India, Indonesia, the Philippines, Thailandand Vietnam.Data on policy effectiveness was obtained from semi-structured interviews with experts on rice straw use, basedat the International Rice Research Institute (IRRI) based in the Philippines. This was combined with a detailedevaluation of existing government policies and a ranking exercise to identify which policy aspects were consideredmost successful to prohibit burning and encourage bioenergy use.Barriers to the widespread use of rice straw which can be categorised into biochemical, logistical andinfrastructural. The biochemical barriers include the low nutritive quality, high lignin and silica content whichcomplicates the breaking down of rice straw into its useful components. The logistical barriers are the wide dispersalof rice straw and intra-annual fluctuations in availability and the resulting issues created in transporting the resourcein sufficient quantity to where it can be utilised at the right time. The final group of barriers include the culturalpractices of rice straw farmers, fossil fuel subsidies skewing the market and the support systems in place forconventional substitutes of rice straw products, such as the infrastructure in place to proces
Mawhood RK, Slade R, Shah N, 2015, Policy options to promote perennial energy crops: the limitations of the English Energy Crops Scheme and the role for agent-based modelling in policy design, Wellesbourne, UK, Association of Applied Biologists: Biomass and Energy Crops V, Publisher: Association of Applied Biologists, Pages: 143-153, ISSN: 0265-1491
The UK government’s bioenergy strategy anticipates the cultivation of between 300,000 and 900,000 ha of energy crops by 2030. Yet policy incentives to promote uptake of perennial energy crops (PECs), notably the English Energy Crops Scheme (ECS), have had little impact. Less than 10,000 ha of PECs were being grown in 2013. To investigate the barriers to deployment a critical literature review and stakeholder interviews were conducted. These identified numerous substantial obstacles regarding PEC economics, alignment with existing institutions and factors affecting risk perception. Many of these are interdependent and involve a broad range of stakeholders. Agent-based modelling is proposed as an approach to explore the cumulative impacts of individual stakeholders’ behaviours under alternative policy and market conditions.
De Jong S, Hoefnagels R, Faaij A, et al., 2015, The feasibility of short-term production strategies for renewable jet fuels – a comprehensive techno-economic comparison, Biofuels, Bioproducts and Biorefining, Vol: 9, ISSN: 1932-104X
This study compares the short-term economic feasibility of six conversion pathways for renewable jet fuel (RJF) production. The assessment combines (i) a harmonized techno-economic analysis of conversion pathways expected to be certified for use in commercial aviation by 2020, (ii) a pioneer plant analysis taking into account technological immaturity, and (iii) a quantified assessment of the merits of co-producing RJF alongside existing European supply chains in the pulp, wheat ethanol, and beet sugar industries. None of the pathways assessed are able to reach price parity with petroleum-derived jet fuel in the short term. The pioneer plant analysis suggests that the hydroprocessed esters and fatty acids (HEFA) pathway is currently the best option; the technology achieves the lowest minimum fuel selling price (MFSP) of 29.3 € GJ−1 (1289 € t−1) and the technology is deployed on commercial scale already. In the short term, nth plant analysis shows hydrothermal liquefaction (HTL) and pyrolysis emerging as promising alternatives, yielding MFSPs of 21.4 € GJ−1 (939 € t−1) and 30.2 € GJ−1 (1326 € t−1), respectively. The pioneer plant analysis shows considerable MFSP increases for producing drop-in fuels using HTL and pyrolysis as both technologies are relatively immature. Hence, further RD&D efforts into these pathways are recommended. Co-production strategies decrease the MFSP by 4–8% compared to greenfield production. Integration of process units and material and energy flows is expected to lead to further cost reductions. As such, co-production can be a particularly useful strategy to progress emerging technologies to commercial scale.

The aviation sector is responsible for an increasing share of anthropogenic CO2 emissions. Wider adoption of aviation biofuels (biojet) is imperative for the reduction of greenhouse-gas emissions, however it represents a radical departure from the existing technological regime of petroleum-based fuels. Further market deployment will require significant techno-economic breakthroughs, as well as adaptation of the existing supply chains and infrastructure.Although a large number of technologies which have the capability to produce such fuels are being developed, many of these are unlikely to be suitable for EU-based production in the short-term. Biojet production pathways vary considerably in terms of their techno-economic features, with the most highly developed being in the very early stages of commercialisation.In this article, the authors map current development and manufacturing efforts within five emerging biojet technological pathways. The research draws upon a comprehensive review of the international academic and grey literature in order to characterise the pathways according to their technological and commercial maturity, as well as progress towards international certification.By implementing the Fuel Readiness Level (FRL) methodology, the authors provide insights regarding not only the current status of the biojet sector, but also potential opportunities for the short-term development of supply chains in the EU.
Speirs J, McGlade C, Slade R, 2015, Uncertainty in the availability of natural resources: Fossil fuels, critical metals and biomass, Energy Policy, Vol: 87, Pages: 654-664, ISSN: 0301-4215
Energy policies are strongly influenced by resource availability and recoverability estimates. Yet these estimates are often highly uncertain, frequently incommensurable, and regularly contested. This paper explores how the uncertainties surrounding estimates of the availability of fossil fuels, biomass and critical metals are conceptualised and communicated. The contention is that a better understanding of the uncertainties surrounding resource estimates for both conventional and renewable energy resources can contribute to more effective policy decision making in the long term. Two complementary approaches for framing uncertainty are considered in detail: a descriptive typology of uncertainties and a framework that conceptualises uncertainty as alternative states of incomplete knowledge. Both have the potential to be useful analytical and communication tools. For the three resource types considered here we find that data limitations, inconsistent definitions and the use of incommensurable methodologies present a pervasive problem that impedes comparison. Many aspects of resource uncertainty are also not commonly captured in the conventional resource classification schemes. This highlights the need for considerable care when developing and comparing aggregate resource estimates and when using these to inform strategic energy policy decisions.

Using biomass to provide energy services is a strategically important option for increasing the global uptake of renewable energy. Yet the practicalities of accelerating deployment are mired in controversy over the potential resource conflicts that might occur, particularly over land, water and biodiversity conservation. This calls into question whether policies to promote bioenergy are justified. Here we examine the assumptions on which global bioenergy resource estimates are predicated. We find that there is a disjunct between the evidence that global bioenergy studies can provide and policymakers' desire for estimates that can straightforwardly guide policy targets. We highlight the need for bottom-up assessments informed by empirical studies, experimentation and cross-disciplinary learning to better inform the policy debate.
