In our now published letter in @pnas.org, we raise two wider issues for behavioral science: 1) Intentions are poor predictors of behavior 2) Effects on intentions need not generalize to effects on behavior We join calls for researchers to measure actual behavior: www.pnas.org/doi/10.1073/...

Despite all the negativity in parts of the press: Change is happening. It’s not a straight line but things are moving. More and more people understand that relying on increasingly volatile and expensive fossil fuel imports is not a viable pathway.

Climate literacy is critical for future business leaders—and MBA programs are evolving to meet this challenge, says Professor Bruce Usher.

Understanding these "six truths" - it's real, it's us, experts agree, it's bad, others care, and there's hope - predicts pro-climate attitudes and support for climate policies, @yaleclimatecomm.bsky.social finds. In particular, (see next post) ...

People think they’re more alone in supporting climate-positive action than they really are. That’s a problem, because we know people are likely to take action when they believe others are already doing so.

The ‘final’ evaluation report of the bus fare cap (covering 10 months of the £2 cap) is now out. Lots to digest here but key point is it did what it was meant to: “The evidence suggests… it has reduced the cost of living and has increased bus patronage, particularly for those on lower incomes.”

Net Zero hinges on behavior change ✅ Decarbonization means shifting our energy choices: how much, how efficiently, when and where we use it. "At the end of the day, the cleanest, most sustainable energy is the energy we never have to use."🤌 Poetry @janrosenow.bsky.social 👏 🔗 shorturl.at/1o68I

The energy transition debate heavily focuses on decarbonising supply. But what if we focused on demand instead? By considering how much, how efficiently, and when we use energy, we unlock a much richer debate and a wider range of solutions. More in my new article 👇 medium.com/@jan.rosenow...

Net Zero needs behavior change. For decarbonization, we need to understand how to enable and encourage green choices (fairly). That’s means shifting: how we heat our homes, how we travel, and what we eat and consume. Don’t ask me, check the latest IPCC report ⬇️ 🔗 www.ipcc.ch/report/ar6/w...
