How can the financial sector be persuaded to play a role in climate action? This poster offers an overview of my findings regarding work conducted by civil society organisations

Accounting and climate change: the two degrees target and financing the transition to a low-carbon economy

This thesis investigates the emergence of the long-term climate target to hold the increase in global average temperature below two degrees Celsius above pre-industrial levels. This ‘two degrees target’ is shown to be the product of efforts to embed climate science, ‘cost-effective’ GHG control, and national sovereignty in a long-term climate goal, and that it became a foundation for work to align the financial sector with the transition to a lowcarbon economy. This thesis investigates how this target envisages an apparently simple and manageable future for addressing climate change, and comes to orient the strategies of diverse and distributed actors towards a common vision. The empirical core of this thesis is a participant observation of a United Nations and Greenhouse Gas Protocol standard-setting project, which is supplemented by semi-structured interviews and documentary analysis. This thesis studies four interrelated instruments, the two degrees target, the carbon budget, investment roadmaps and an emergent carbon accounting standard. It focuses on the work involved in assembling and adjusting these instruments, attending to the efforts to produce coherent and stable linkages between ideas of climate governance and the local specifics of the financial sector. This thesis shows how a carbon-constrained future with financial sector implications was envisaged. It also traces how ideas stemming from the two degrees target shifted the development of finance-specific carbon accounting practices away from greenhouse gas data and towards metrics for managing risk and monitoring alignment with investment roadmaps. This thesis, as a whole, contributes to our understanding of carbon accounting as a practice that embeds diverse modes of climate governance and coordinates action across multiple entities. It shows the processes through which an apparently simple vision for addressing climate change began to orient diverse and distributed efforts towards financing the transition to a low-carbon economy

2-Substituted agelasine analogs : synthesis and biological activity, and structure and reactivity of synthetic intermediates

2-Substituted N-methoxy-9-methyl-9H-purin-6-amines were synthesized either from their corresponding 6-chloro-9-methyl-9H-purines or 2-chloro-N-methoxy-9-methyl- 9H-purin-6-amine. Great diversity in the amino/imino tautomeric ratios was observed and calculated based on 1H NMR. The tautomers were identified by 1D and 2D 1H, 13C, and 15N NMR techniques, and showed significant variation both in 13C and 15N shift values. Comparison of the tautomeric ratios with Hammett F values revealed that as the field/inductive withdrawing abilities of the 2-substituent increased, the ratio of amino:imino tautomers was shifted toward the amino tautomer. Computational chemistry exposed the significance of hydrogen bonding between solvent and the compound in question to reach accurate predictions for tautomeric ratios. B3LYP/def2-TZVP density functional theory (DFT) calculations resulted in quantitatively more accurate predictions than when employing the less expensive BP86 functional. N-7-Alkylation of the 2-substituted N-methoxy-9-methyl-9H-purin-6- amines showed that when the field/inductive withdrawing ability of the 2-substituent reached a certain point the reactivity drastically dropped. This correlated with the atomic charges on N-7 calculated using a natural bond orbital (NBO) analysis. Biological screening of the final 2-substituted agelasine analogs indicated that the introduction of a methyl group in the 2-position is advantageous for antimycobacterial and antiprotozoal activity, and that an amino function may improve activity against several cancer cell lines

The value of research activities "other than" publishing articles: reflections on an experimental workshop series

Purpose: The purpose of this essay is to explore the opportunities and challenges that early-career researchers (ECRs) face when they seek to contribute to academic knowledge production through research activities “other than” those directly focused on making progress with their own, to-be-published, research papers in a context associated with the “publish or perish” (PoP) mentality. / Design/methodology/approach: Drawing broadly on the notion of technologies of humility (Jasanoff, 2003), this reflective essay develops upon the experiences of the authors in organizing and participating in a series of nine workshops undertaken between June 2013 and April 2021, as well as the arduous process of writing this paper itself. Retrospective accounts, workshop materials, email exchanges and surveys of workshop participants provide the key data sources for the analysis presented in the paper. / Findings: The paper shows how the organization of the workshops is intertwined with the building of a small community of ECRs and exploration of how to address the perceived limitations of a “gap-spotting” approach to developing research ideas and questions. The analysis foregrounds how the workshops provide a seemingly valuable research experience that is not without contradictions. Workshop participation reveals tensions between engagement in activities “other than” working on papers for publication and institutionalized pressures to produce publication outputs, between the (weak) perceived status of ECRs in the field and the aspiration to make a scholarly contribution, and between the desire to develop a personally satisfying intellectual journey and the pressure to respond to requirements that allow access to a wider community of scholars. / Originality/value: Our analysis contributes to debates about the ways in which seemingly valuable outputs are produced in academia despite a pervasive “publish or perish” mentality. The analysis also shows how reflexive writing can help to better understand the opportunities and challenges of pursuing activities that might be considered “unproductive” because they are not directly related to to-be-published papers

Insights into plant biomass conversion from the genome of the anaerobic thermophilic bacterium Caldicellulosiruptor bescii DSM 6725

Caldicellulosiruptor bescii DSM 6725 utilizes various polysaccharides and grows efficiently on untreated high-lignin grasses and hardwood at an optimum temperature of ∼80°C. It is a promising anaerobic bacterium for studying high-temperature biomass conversion. Its genome contains 2666 protein-coding sequences organized into 1209 operons. Expression of 2196 genes (83%) was confirmed experimentally. At least 322 genes appear to have been obtained by lateral gene transfer (LGT). Putative functions were assigned to 364 conserved/hypothetical protein (C/HP) genes. The genome contains 171 and 88 genes related to carbohydrate transport and utilization, respectively. Growth on cellulose led to the up-regulation of 32 carbohydrate-active (CAZy), 61 sugar transport, 25 transcription factor and 234 C/HP genes. Some C/HPs were overproduced on cellulose or xylan, suggesting their involvement in polysaccharide conversion. A unique feature of the genome is enrichment with genes encoding multi-modular, multi-functional CAZy proteins organized into one large cluster, the products of which are proposed to act synergistically on different components of plant cell walls and to aid the ability of C. bescii to convert plant biomass. The high duplication of CAZy domains coupled with the ability to acquire foreign genes by LGT may have allowed the bacterium to rapidly adapt to changing plant biomass-rich environments

Paleocene methane seep and wood-fall marine environments from Spitsbergen, Svalbard

A recently discovered Paleocene seep locality from Fossildalen on Spitsbergen, Svalbard, is described. This is one of a very few seep communities of the latest Cretaceous–earliest Palaeogene age, and the best preserved Paleocene seep community known so far. The seep carbonates and associated fossils have been first identified in museum collections, and subsequently sampled in the field. The carbonates are exclusively ex-situ and come from the offshore siltstones of the Basilika Formation. Isotopically light composition (δ13C values approaching -50‰ V-PDB), and characteristic petrographic textures of the carbonates combined with the isotopically light archaeal lipid are consistent with the formation at fossil hydrocarbon seep. The invertebrate fauna associated with the carbonates is of moderate diversity (16 species) and has a shallow water affinity. It contains a species of the thyasirid genus Conchocele, common in other seeps of that age. The finding sheds new light onto the history of seepage on Svalbard, and onto the evolution and ecology of seep faunas during the latest Cretaceous–earliest Palaeogene time interval
