Global warming and some climate change policies pose additional social risks that necessitate novel responses from the welfare state. Eco-social policies have significant potential to address these challenges, but their wide-scale adoption will depend, among other factors, on public support. In the current article, we theorise how public opinion about eco-social policies is likely to be influenced by a set of contextual and individual-level factors, as well as the perceived welfare deservingness of the target groups. Alongside contributing to the emerging body of literature on eco-social policies, this theoretical framework could help policymakers to anticipate the social groups that will support or oppose eco-social policy agendas and how some of the contradictions could be reduced through policy design.

The year 2020 proved to be a clarion call for global society. There is no longer doubt that increasingly we are experiencing unpredictable events, known as ‘black swans’, ranging from pandemics to financial meltdowns. One of the ’climate black swans’ against which experts have cautioned is the financial crisis caused by climate change. In this context, the Australian case of McVeigh v. Retail Employees Superannuation Trust for the first time tested climate risk and the fiduciary duties of retail pension funds. Settled in November 2020, the case has already raised the bar for climate risk practice in pension funds. In particular, McVeigh suggests that courts, as well as out-of-court settlements, may articulate a duty, rather than grant permission, for pension funds to consider climate-related financial risk in their investment decisions.

The article builds on McVeigh to ask two questions. Firstly, what is the role of climate change litigation in promoting climate regulation by pension funds? Secondly, what is the relative importance of pension funds for the risk management of climate-related financial risk via due diligence compared with risk assessment via disclosure? Fundamentally, the article explains climate-related financial risk as a cultural phenomenon and argues that a discussion on pension fund fiduciary duties must consider disclosure in addition to due diligence. It argues that McVeigh articulated the need for a normative approach to pension fund disclosure duties and an extension of the field of climate-related risk disclosure to embrace climate-related risk due diligence.

Access to affordable, reliable and sustainable energy is a pre-condition for sustainable economic development. This is the case in South Africa, where the workforce and entrenched fossil fuel industry remain sceptical about a transition to renewable energy. This article explores the complexity of energy regulation in countries with a deep-seated economic dependency on fossil fuels. South Africa presents a good case study of the challenge of balancing the environmental, social and economic imperatives of energy. It unpacks the drivers behind directed regulation towards renewable electricity. A painful, but necessary, “just transition” to a low-carbon economy requires laws to phase-out fossil fuels, without exposing public funds to private profit seekers. The South African experience of renewable electricity demonstrates the challenges of regulatory uncertainty. Careful legal reforms are necessary to rid existing electricity laws of their inertia and achieve a low-carbon economy while ensuring access to affordable, reliable and environmentally sustainable energy.

While the intergovernmental climate regime increasingly recognizes the role of non-state actors in achieving the goals of the Paris Agreement (PA), the normative linkages between the intergovernmental climate regime and the non-state dominated ‘transnational partnership governance’ remain vague and tentative. A formalized engagement of the intergovernmental climate regime with transnational partnerships can increase the effectiveness of partnerships in delivering on climate mitigation and adaptation, thereby complementing rather than replacing government action. The proposed active engagement with partnerships would include (i) collecting and analyzing information to develop and prioritize areas for transnational and partnership engagement; (ii) defining minimum criteria and procedural requirements to be listed on an enhanced Non-state Actor Zone for Climate Action platform; (iii) actively supporting strategic initiatives; (iv) facilitating market or non-market finance as part of Article 6 PA; and (v) evaluating the effectiveness of partnerships in the context of the enhanced transparency framework (Article 13 PA) and the global stocktake (Article 14 PA). The UNFCCC Secretariat could facilitate engagement and problem solving by actively orchestrating transnational partnerships. Constructing effective implementation partnerships, recording their mitigation and adaptation goals, and holding them accountable may help to move climate talks from rhetoric to action.

The present article describes the main insights deriving from the papers collected in this special issue which jointly provide a ‘room with a view’ on some of the most relevant issues in climate policy such as: the role of uncertainty, the distributional implications of climate change, the drivers and applications of decarbonizing innovation, the role of emissions trading and its interactions with companion policies. While looking at different issues and from different angles, all papers share a similar attention to policy aspects and implications, especially in developing countries. This is particularly important to evaluate whether and to what extent the climate policies adopted thus far in developed countries can be replicated in emerging economies.

The agriculture and food sectors contribute significantly to greenhouse gas emissions. About 15 percent of food-related carbon emissions are channeled through restaurants. Using a contingent valuation (CV) method with double-bounded dichotomous choice (DBDC) questions, this article investigates U.S. consumers’ willingness to pay (WTP) for an optional restaurant surcharge in support of carbon emission reduction programs. The mean estimated WTP for a surcharge is 6.05 percent of an average restaurant check, while the median WTP is 3.64 percent. Our results show that individuals have a higher WTP when the surcharge is automatically added to restaurant checks. We also find that an information nudge—a short climate change script—significantly increases WTP. Additionally, our results demonstrate that there is heterogeneity in treatment effects across consumers’ age, environmental awareness, and economic views. Our findings suggest that a surcharge program could transfer a meaningful amount of the agricultural carbon reduction burden to consumers that farmers currently shoulder.

This paper analyses the role that companion policies have had in the reduction of emissions regulated by the EU Emissions Trading System (EU ETS) and the related policy interactions, with a view to identifying relevant insights for China's forthcoming Emissions Trading System (ETS). The investigation rests on: (a) the observation of the EU's and China's ETSs and policy mixes; (b) economic theory concerning companion policies and ETS design; and (c) empirical ex-post evidence from the EU ETS. Three main conclusions emerge from the analysis. First, China's ETS, while not imposing a fixed cap on emissions, will not be immune to waterbed effects of companion policies. Second, the European experience stresses the importance of making explicit the objectives pursued by companion policies, and of balancing policies for innovation and policies for adoption of low-carbon technologies. Third, in the presence of a major market surplus, only permanent adjustments to allowance supply can be effective in raising prices.

Finding the ways that work to deliver the innovation needed should be given parity of esteem with getting the prices right as a focus of the economics profession and policy systems. Learn from experience as regards carbon pricing and carbon-reducing innovation; insights from the latter coming mainly from the US, China and Europe; demographically relatively small countries – Denmark (wind) and Australia (solar PV) – can make outsize contributions. A carbon price ceiling is too low to drive innovation; generating carbon-reducing innovation requires that it be explicitly recognized as a priority, and nurtured accordingly: identify the priority area(s) where innovation at scale will be necessary to make progress; baseline the elements of the innovation ecosystem which are already in place, and the gaps that need to be filled. Key elements include institutions and incentives that promote innovation, a research and enterprise community that make it happen, and a supportive public.

Conserving tropical forests has many benefits, from protecting biodiversity, sustaining indigenous and local communities, and safeguarding climate. To achieve the ambitious climate goals of the Paris Agreement, forest protection is essential. Yet deforestation continues to diminish the world's forests. Halting this trend is the objective of the international framework for Reducing Emissions from Deforestation and forest Degradation (REDD+). While previous studies have demonstrated the contribution of tropical forests to mitigate climate change, here we show that tropical forest protection can ‘flatten the curve’ of the costs of transition to climate stability, estimating tens of trillions of dollars in policy cost savings.

Australia has committed to reducing emissions under the Paris Agreement by 2030, in alignment with the United Nations' (UN) Sustainability Development Goal (SDG) climate action. This article investigates the responses of Australian high-emission businesses to Australian government action and legislation in relation to climate change, specifically the carbon tax, and how this knowledge can assist in delineating future carbon legislation. A qualitative study of the responses of 17 high-emission businesses and three industry associations to carbon legislation during the implementation of the carbon tax in Australia identified the use of resistive, reactive or cooperative strategies by the businesses. Issues related to carbon legislation identified by businesses included differences in time orientation, multiple regulations, political uncertainty, international positioning and the need for long-term and consolidated policies. Given these findings, this article argues that well-designed top-down legislative measures are necessary to steer businesses towards a carbon-neutral regime.

A small benefit of the disastrous COVID-19 pandemic has been the temporary reduction in greenhouse gas emissions. Therefore, this paper asks: what strategies can return people to work without returning to the old high-emissions economy? How can we modify the old economic system to reduce environmental impacts while rebuilding employment? Technological change, such as replacing fossil fuels with renewable energy (RE), is necessary but, in an economy that's growing, unlikely to be sufficiently rapid to avoid dangerous climate change. Degrowth in physical consumption, especially by the ‘rich’ 10%, towards a steady-state economy, is needed as well as low-carbon jobs.
