🚨✈️ New paper on support for carbon taxation targeting air travel in Denmark 🇩🇰 We ran a discrete choice experiment with oversampling of top-income individuals to examine how policy design, information, and individual characteristics shape support. 🧵 (1/3) papers.ssrn.com/sol3/papers....

🌍 New megastudy on what motivates people to engage in climate advocacy 🥳 We tested 17 theory-driven behavior change interventions to increase public, political, and financial #climate advocacy in the United States (N = 31,324). academic.oup.com/pnasnexus/ar...

New study finds that emphasizing collective efficacy (people's ability to catalyze large-scale change) is very effective in catalyzing behavioural change. As you can see from my pinned post, I'm a big fan of simple messages that can mobilize public support for climate action!

Speaker Spotlight: Kristian Nielsen How do individual behavior change & broader systems change interact? How can behavioral science realize its full potential to address climate change? We're excited to have @kristiansn89.bsky.social help us tackle these questions! ⏳ Apply until Jan 26: acscc.nl

1/ Yes the globally wealthy have outsized emissions, and yes that’s a massive problem But it’s actually only a small part of their devastating influence on the conditions that support life 🧵

4/ In fact, as @kristiansn89.bsky.social, @kimberlynicholas.bsky.social & colleagues show, 'high-socioeconomic-status' people collectively work to prevent serious action on climate in a range of ways both conscious and unconscious www.nature.com/articles/s41...

Noam Chomsky has repeatedly called the U.S. Republican Party the most dangerous organization in the world. It gets harder and harder to disagree. www.bbc.com/news/av/worl...

🔥How can behavioral science contribute more to tackling climate change? This question has been on my mind for years, and I have often written rather critically about the state of behavioral science research (including my own). Here I will share six recommendations🧵 www.nature.com/articles/s41...

Adds evidence about the false (in my opinion) dichotomy between support for individual actions and for systems change

What better way to end 2025 than getting our paper published in Global Environmental Change 🥳💚 We studied perceptions of the feasibility of climate-relevant behavior change and how these perceptions connect to income differences and climate policy support. Let me tell you all about it🧵👇

Being serious about planetary boundaries means transforming towards less and slower mobility. This contradicts the current paradigms, making it difficult to gain legitimacy for such policies. Slow mobility also means more active and healthy mobility. High time to link health psychology and mobility.

Vi har i Klima- og Omstillingsrådet en kronik i @altingetdk.bsky.social om, hvorfor Danmark bør arbejde langt mere aktivt med vores forbrugsbaserede klimaaftryk 🇩🇰 Her adresserer vi også den ensporede kritik, som klimaministeren fremfører. @jenslund.bsky.social www.altinget.dk/klima/artike...

Walk and chew, people. Walk and chew.

This is the problem with trying to inspire hope using the message "we have the solutions": such a message may inspire the kind of techno-optimism that actually fosters political *dis*engagement. 1/n

Nearly every panel I spoke on this year ended with the same question: "What gives you hope?" My friends, that question expired years ago. (If you need receipts, my book Saving Us is literally a 300-page answer.) The real question is: How are you PRACTICING hope? Because Greta is right ..

⚠️ When “technology will save us” becomes a climate risk! A new paper from great colleagues takes a careful look at techno-optimism — the belief that technology will largely solve climate change — and what it means for real-world climate action. (1/4)👇 osf.io/preprints/ps...

For at oversætte forskningen til almindeligt dansk: Sorter endeligt dit affald, men tro ikke, at det har nær samme effekt som at skære ned på flyrejserne og de røde bøffer. #dkpol #dkgreen

✈️🥩♻️ How accurately do people perceive the #climate impact of different lifestyles — and how do those perceptions relate to their own behavior and policy preferences? Our new study investigated exactly this in China, Germany, and the US.🧵 www.sciencedirect.com/science/arti...

A great thread I had previously missed 👇

Data shows wealthiest 0.1% of the US burn carbon at 4,000 times the rate of the world’s poorest 10% www.theguardian.com/environment/...

A must read for anyone who wants to understand behavior change as a part of climate action 👇

⭐ After quite some time in the making, I’m excited to share our new paper!🌿⭐ We examined people's climate-relevant behaviors (driving, air travel, public transport use, and meat consumption) and their perceptions of how feasible it would be to change them (+ expected wellbeing impacts). 🧵(1/4)

This! 🔥👇 Couldn't agree more, thank you @kristiansn89.bsky.social

Systems change is brought about by the collective actions of individuals. So individual actions, when supporting systems change, is absolutely fundamental to climate action.

This is spot on. Taking action in my personal life also provides me with a sense of purpose and progress when the broader world often disappoints. Always remember, you make a difference.

So in short… personal change will never save the world on its own, but it is indispensable if we want the systemic change that can! That is why the head of the OPEC has also claimed individual actions to be their biggest enemy! They know this!

I cannot agree more Kristian! I think you miss one thing though... Western democracy is build short term renewed power intervals. That means power needs to take notes of what the people wants. And when people show power that they want change, by changing, change can happen. If they dont. It wont!

This is a really important point. Changing these behaviours now does two things: 1.Makes a start on the drastic lifestyle changes and gets communities thinking creatively and in solidarity 2. Sends a strong political message to #government and #business

A much more eloquently put thread on a point I continually find myself trying to make! #individualaction #lifestylechangenotclimatechange #flightfree

Excellent thread. I agree 100% with this set of actions. Every item I recycled, every option to avoid fossil fuel use, every alternative to electricity use, adds up over the years. Multiply by millions of people, it quickly adds up. Paper packaging, aluminum containers, plant based cleaners… 1/

🔥 The never-ending narrative… This week, I’ve once again heard prominent climate researchers dismiss individual action as either irrelevant or a distraction instigated by the fossil fuel industry. Here’s a 🧵 on why this argument frustrates me to no end and why I think it misses the bigger picture.

♻️ New paper in Journal of Environmental Psychology 🙌 We examined subtraction neglect — the tendency to prioritize additive over subtractive climate strategies (e.g., buying an EV vs. flying less) when thinking about effective personal actions. Check it out! 🙃 www.sciencedirect.com/science/arti...

🌿🦋 Biodiversity conservation is, at its core, about changing human behavior. Whether it’s the consumer choices driving unsustainable demand, land managers clearing habitats, or policymakers failing to act – #biodiversity loss is tightly bound to human behavior🧵 www.sciencedirect.com/science/arti...

🌍🇩🇰 Nyt indlæg i @altingetdk.bsky.social Danmark kaldes ofte et grønt foregangsland. Men vores forbrugsbaserede klimaaftryk er ca. 50% højere end de territoriale udledninger. Hvis vi vil være et ægte grønt foregangsland, kræver det et forbrugsbaseret klimamål og en strategi for adfærdsændringer...

This is an amazingly helpful resource for guiding you to take meaningful and effective #climate action in your context 😍🌎

🦋🌱 Most people care about #biodiversity, yet we often underestimate how concerned others are about its loss. This “pluralistic ignorance” can silence people, weaken action, and make ambitious policies seem less popular. In a new paper, we outline a research agenda to study and reduce this gap (1/2)

"Changing what we demand and how we live could reduce global emissions by 40–70%" This is why we encourage individual behaviour change – not in place of system change and government action, but as a vital part of it. Take the Flight Free Challenge today: flightfree.co.uk#take-the-cha...

🌍🚨 We cannot solve the climate crisis without demand-side solutions! The @ipcc.bsky.social is crystal clear: changing what we demand and how we live could reduce global emissions by 40–70% by 2050. This is not a marginal add-on. It must be at the heart of climate policy🧵 www.ipcc.ch/report/ar6/w...

🌏 𝗪𝗵𝗮𝘁 𝗺𝗼𝘀𝘁 𝗼𝗳 𝘂𝘀 𝗴𝗲𝘁 𝘄𝗿𝗼𝗻𝗴 𝗮𝗯𝗼𝘂𝘁 𝗻𝗮𝘁𝘂𝗿𝗲 𝗰𝗼𝗻𝘀𝗲𝗿𝘃𝗮𝘁𝗶𝗼𝗻 It’s not that people doubt biodiversity is declining—it’s that we underestimate how many others already share this concern. In our new Perspective, we review work on pluralistic ignorance and set out a research agenda to:

"Scientists and modelers have not merely warned of the #ClimateCrisis - they have also, often unwittingly, contributed to it by reinforcing an uncritical faith in technological salvation & sidelining more structural social transformations" www.sciencedirect.com/science/arti...

The Department of Energy hired five academics to raise doubts about climate change. 85+ climate experts (organized by @andrewdessler.com) reviewed their report. Our conclusion, detailed in 450 pages of analysis: it is biased, full of errors, and not fit to inform policy making.
