Citizen deliberation in Net Zero governance: learning lessons and looking forward
,Abstract
Since 2019, public and third-sector bodies across the UK have been experimenting with citizens’ juries and assemblies in the context of net-zero governance—collectively referred to in this essay as ‘climate assemblies’. These assemblies bring together a representative sample of citizens to learn about and discuss policy issues, prior to making recommendations for action. With the UK off track to meet it’s 2030 climate targets, advocates hope these fora can drive policy on net zero that is both ambitious and garners public support. This essay draws on social science evidence to appraises the recent wave of climate assemblies against four often-cited objectives for such processes: providing knowledge to policymakers about public preferences and lived experiences; encouraging policy action by demonstrating a public mandate; improving public trust in leaders and governance institutions; and providing a mechanism for oversight and accountability. We show that the first of these objectives has largely been met. Climate assemblies have also succeeded in demonstrating a mandate in terms of proposals being consistently ahead of existing policy, although there are no clear cases of climate assemblies increasing policy ambition. Climate assemblies can help build trust amongst those taking part, but this dissipates if the commissioning body is not subsequently seen to act. Climate assemblies are not widely known about amongst the wider population, and there is a lack of evidence on how they impact trust perceptions amongst those who do hear of them. Finally, there are very few examples of assemblies being tasked with an oversight or accountability role, an area we suggest could benefit from further experimentation. We conclude with a series of recommendations for further embedding climate juries within net-zero governance, aimed at improving their ability to contribute to the net-zero transition. This article is published in the thematic collection ‘The critical role of governance for decarbonisation at pace: learning the lessons from SHAPE research’, edited by Sarah Birch, Hilary Graham, Andrew Jordan, Tim O’Riordan, Henry Richards.

| Climate Assembly UK, 2020 | Commissioned by six Select Committees of UK Parliament. Final report sent to Committees in September 2020. Committees held short inquiry on the uptake of results within government, which reported in July 2021. | Committees scrutinised degree to which government had taken up recommendations. Though only held one evidence session and produced one report (BEIS Committee 2021). There is no compelling evidence that recommendations were a factor in later government decision making (Duvic-Paoli 2022; Carrick & Elstub 2024). |
| Scotland’s Climate Assembly, 2020–1 | Commissioned by the Scottish Government. Secretariat maintained beyond life of assembly to oversee engagement with government officials and members of Parliament. | One third of recommendations that matched existing or planned policies were actioned by government. Others were either abandoned, considered too broad to be actionable, or were deemed to be out of remit (Andrews et al. 2022). |
| Oxford Citizens’ Assembly on Climate Change, 2019 | Commissioned by Oxford City Council as part of Climate Emergency Declaration. | Findings ‘created momentum’ and reassured politicians of public support. Council followed up with a £19 million funding package to support decarbonisation (Wells et al. 2021). |
| Objective | Evidence of success to date | Design considerations |
|---|---|---|
| Knowledge provision | Climate assemblies have proven effective in helping policymakers understand the potential reception and impacts of different policy options. | ∙ Commissioning bodies do not need to be empowered. Civil servants and government agencies can use assemblies as part of evidence gathering. ∙ Coupling with surveys and opinion polls can assist in building a detailed picture of public preferences. ∙ Expectations of participants and stakeholders need to be managed from the outset. |
| Mandate for action | Climate assemblies have been effective in giving confidence to policymakers already intending to bring forward climate policies. They have been less effective at compelling additional action to that already planned. | ∙ The commissioner should be the body empowered to act. ∙ The specific policy or initiative that the assembly is to feed into should be clear from the outset. ∙ The commissioner should make clear how they will use and respond to recommendations. |
| Increased trust | Climate assemblies have increased trust in institutions amongst those taking part, though this has diminished due to lack of follow-through. There has been limited impact on feelings of trust and political efficacy amongst the wider public. | ∙ Commissioners should make clear from the outset how proposals will be used and responded to. ∙ Commissioners should establish clear lines of communication with participants and wider publics/stakeholders, and provide regular updates on how proposals are being used. ∙ Governance structures should continue beyond the life of the assembly, to trace the use of proposals and hold commissioners accountable for commitments made. ∙ A communication strategy should be considered to engage the wider public in the process and findings. |
| Oversight and accountability | Climate assemblies have largely not been tested in an oversight and accountability function. | ∙ Could be instituted ‘upstream’ where policy decisions are made, or ‘downstream’ where decisions are enacted. ∙ Would require governance structures at least partially independent of the body being scrutinised. ∙ Could involve a ‘trigger mechanism’ where civil society groups or publics are able to trigger a deliberative process to evaluate decisions ex post. |

This article introduces the Thematic Collection ‘Decolonising Gender Knowledge in Sub-Saharan Africa: Empirical Insights and Theoretical Innovations from Early Career Researchers’, edited by Alicia Bowman, Evelyn Garwe and Juliet Thondhlana. It highlights the under-representation of Global South scholars, particularly early career researchers (ECRs), in gender knowledge production in the region and advocates for grounding the study of gender in Africa in local realities and knowledge systems, in line with African feminist perspectives. Moreover, the article positions the collection as a powerful step towards decoloniality not simply by amplifying African perspectives, but by actively creating space for African scholars to shape the future of gender studies. The article discusses how the Thematic Collection fostered the co-production of knowledge by empowering African scholars to develop their own research questions and methodologies, free from Eurocentric constraints, thus promoting complete epistemic freedom. It also showcases the interdisciplinary nature of the Thematic Collection, spanning gender studies, higher education, and legal, labour, and urban studies. Overall, the introduction argues that, by centring the research of African ECRs, established power dynamics can be disrupted, and the dominance of Western-centric paradigms can be challenged.
Young people worldwide are engaged in diverse forms of participation which offer a pathway for demanding accountability from governance actors. In contexts with fragile governance structures, young people face a unique set of challenges in their efforts to demand accountability or participate in decision-making. The expected relationship between participation and accountability as understood in liberal, democratic settings is often absent and instead demands for accountability are often made through strategies ‘at the margins’. Using Palestine as a case study, we show how young people look for accountability beyond state institutions and the national scale, using diverse strategies depending on their embedded position in society. This analysis sheds light on the complex reality of youth participation and accountability mechanisms in socially, politically and physically contested spaces and, by extension, points towards challenges and opportunities in implementing the Sustainable Development Goals.
