Gas spent 20 years owning the evening peak. Batteries took a year to crash the party. That's disruption. Not gradual, but a rapid shift in who supplies grid's most valuable hours. The battle was never about total generation. It was about the peak & batteries are winning it. #Bettrification #BESS

In line with an emerging strand of research showing that 'green grievances' translate into far-right support, I find suggestive evidence that potential losers increased their support for minor far-right parties.

Claudia Zwar @claudiazwar.bsky.social · 03/03/2026
I find that potential losers in export communities resoundingly rejected the pro-climate party (~ 4.6 pp per polling station), despite not being targeted by the proposed policies. Actual losers, who were offered compensation, did not.

Claudia Zwar @claudiazwar.bsky.social · 03/03/2026
I test this argument in Australia, focusing on 2019, when a major party proposed an ambitious climate agenda. Leveraging heterogeneity in the coal industry, I estimate voters' responses in communities reliant on domestic ('actual losers') and export coal ('potential losers') in a DID design.
120
Claudia Zwar @claudiazwar.bsky.social · 03/03/2026
These voters present a strategic dilemma for the pro-climate party. Offering compensation to all potential losers may be infeasible and could signal the scale of the losses. But this provides an opening for rival parties to exploit policy uncertainty to mobilise uncompensated potential losers.
130
Claudia Zwar @claudiazwar.bsky.social · 03/03/2026
I argue that, ex-ante, a key constituency are 'potential losers': those who do not face clear costs under proposed policies but are vulnerable to the knock-on or future consequences of the green transition.

Claudia Zwar @claudiazwar.bsky.social · 03/03/2026
Much research on the political consequences of structural change analyses how voters punish parties for impacts like job losses and energy price hikes. How do voters respond to a proposed climate agenda whose costs have not yet materialised?

Why are we observing a 'green backlash' when serious efforts to decarbonise have scarcely begun? I'm happy to share my working paper, 'The Political Consequences of Climate Ambition: Evidence from Australia', which analyses how voters respond prospectively to proposed climate policies. Brief 🧵:

This has been a tumultuous week in Australian climate politics! And a good example of how target setting becomes a focal point for agenda-setting on climate, as per @jacobedenhofer.bsky.social, @chflachsland.bsky.social and my paper (below) www.theguardian.com/australia-ne...

Bowen says cutting emissions by more than 70% ‘not achievable’ as 2035 target criticised from all sides
Albanese says 62% to 70% range represents ‘the sweet spot’ as Coalition rejects ‘economy wrecking’ target while Greens label it a ‘betrayal’

work with @claudiazwar.bsky.social on climate institutions. Policy instruments span market-based tools (e.g. carbon pricing, ETS) and non-market approaches (e.g. standards, subsidies). Instrument design structures distributive outcomes and thus reshapes coalitional politics. bsky.app/profile/clau...

🚨Global public action (climate!) is most effective when countries do it together yet we're in a period of IO backlash rooted in left-behind places Does it mean all left-behind regions hate IOs the same? @patrickbayer.bsky.social & I have a paper accepted @bjpols.bsky.social abt this🧵 osf.io/rtymv
Climate Policy Costs, Regional Politics and Backlashagainst International Cooperation by Patrick Bayer and Federica Genovese.

This paper investigates the conditions under which subnational concerns shape public assessments of international climate governance. In line with existing literature, we maintain that costly policy adjustments fuel negative views of international cooperation in policy exposed regions. At the same time, we argue that the more resentful relations are with the national center of politics, the more sympathetic these regions areto international institutions and global governance. Based on geographically targeted survey data from theUnited Kingdom, we find that fossil fuel-intensive regions with strong, institutionalized regional politics have more positive assessments of international climate cooperation than structurally similar regions where regional political institutions are less pronounced. The findings show that regional politics characteristics are key for understanding climate policy beliefs among citizens that bear the brunt of adjustments to international climate agreements

We also demonstrate how policymakers can use the CIAF to create or reform climate institutions in their own countries, learning from comparative analysis. This matters because CIs are easier to reform than macro-political institutions (e.g. electoral rules) (5/5)
132
Claudia Zwar @claudiazwar.bsky.social · 04/09/2024
We apply the CIAF to analyse CIs in DEU, GBR, SWE, and AUS. We find CIs in these countries tend to address knowledge and attention-related strategic challenges, while failing to deliver compensation for affected groups or ex-ante accountability (4/5)
132
Claudia Zwar @claudiazwar.bsky.social · 04/09/2024
We propose 2 novel theoretical tools: (i) an encompassing + replicable definition of CIs and (ii) a framework to analyse their effects. The CIAF sees CIs as addressing a series of 'strategic challenges' in climate policy and engendering effects via 'stylised causal chains' (3/5)
122
Claudia Zwar @claudiazwar.bsky.social · 04/09/2024
CIs - including framework climate legislation, climate advisory bodies, and climate ministries - have proliferated globally. Yet, compared with policy instruments, we know relatively little about them and the role they play in effective climate change mitigation (2/5)
