Widespread diet change is not new. Don't tell me we can't green the food system 🥗 A history lesson ⬇️ 🥔 ~1500s. Potatoes are introduced to Europe: Initially nicknamed ‘devil’s apples’, people suspected potatoes were poisonous. Nowadays, traditional European cuisine is unimaginable without it 🧵⬇️

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.

🧠🌍 Can you correct misperceptions of the impact of different climate actions? In a new @pnasnexus.org paper, we tested whether climate action literacy interventions can shift behavioral commitments toward more effective climate actions. Check out our neat results 🙂 academic.oup.com/pnasnexus/ad...

Climate action literacy interventions increase commitments to more effective mitigation behaviors

Abstract. Reducing lifestyle carbon emissions is a critical component of decarbonizing society. However, people hold substantial misperceptions about the r

✨New✨ climate report makes one thing clear about Net Zero... 🔋Electrification 🔋Electrification 🔋Electrification Behaviorally: 📈 37% of CO₂ reductions come from household behavior changes 📈 72% of these reductions come from electrification: EVs (40%), heat pumps (30%). Chuffed to be cited 😊 🧵⬇️

A pie chart and bar chart illustrating the share of emissions reduction in 2040 that relies on household low-carbon choices. The pie chart shows that 37% of emissions reduction comes from household choices, while 63% does not. The bar chart breaks down household-driven reductions: 42% from electric vehicles, 30% from low-carbon heating, 6% from reduced meat and dairy consumption, 1% from land-use changes due to diet shifts, 6% from maintaining current flying levels, 4% from energy efficiency in homes, 3% from modal shifts, and 8% from other smaller actions (e.g., waste reduction, recycling, efficient appliances).

Study on London 20 mph limits shows: - collisions ⬇️ 35% - casualties ⬇️ 36% - fatal/serious injuries ⬇️ 34% - child casualties ⬇️ 46% - child deaths ⬇️ 75% - walkers, cyclists, motorcyclists killed/seriously injured ⬇️ 28% etsc.eu/20mph-limits...

20mph limits in London linked to sharp fall in road injuries and deaths, new report finds

A new study published by Transport for London (TfL) has shown that the introduction of 20mph speed limits and zones on local authority-managed roads in London between 1989 and 2013 led to significant…

Incredible findings on impact of LEZ & ULEZ ⬇️ significantly reduced PM10 & NO2 levels ⬇️ sick leave reduced by 18.5% ⬆️ improved general health ⬇️ reduced incidence of long-term health conditions and respiratory issues ⬆️ mental well-being & happiness 💷 est. savings exceeding £37 million per year

Air pollution poses a global concern due to its detrimental effects on climate, healthcare, and human capital accumulation. However, there is limited evidence on the health and human capital impacts of clean air transport policies. This study investigates the effects of London’s Low Emission Zone (LEZ) and Ultra-Low Emission Zone (ULEZ) on air quality, sick leave, well-being, and physical health. By exploiting the temporal and spatial variations of these policies – implemented in Greater London (LEZ) in 2008 and Central London (ULEZ) in 2019 – we implement a difference-in-differences approach utilising linked survey and administrative data. We show that the LEZ and ULEZ policies significantly reduced  and levels. Consequently, we observe substantial improvements in labour productivity, with sick leave reduced by 18.5% from pre-LEZ levels. The ULEZ contributed to enhanced mental well-being, as evidenced by increased feelings of happiness, worthiness and satisfaction, along with a reduction in anxiety. These effects are further supported by improvements in physical health, with the LEZ reducing the incidence of long-term health conditions by 6.8% and respiratory issues by 10.2%. A back-of-the-envelope cost–benefit analysis suggests that the policies generated savings exceeding £37 million per year for the overall population.

WHEN do people change their travel habits? ⏰⌛🚗🚌🚴‍♀️ Loved unpacking 'moments of change' with the UK Department for Transport We asked how disrupting habits shifts travel choices: How might moving home change how you commute? Injury tamper cycling⁉️ The list goes on ⬇️🧵 🔗➡️ shorturl.at/alwIj

The image is the cover page of a report from the Department for Transport (UK government). The title of the report is:

"Moments of Change: How to enhance the effectiveness of behavioural interventions in travel"

The publication date is March 2025.

It features a clean, modern design with overlapping geometric shapes in green and grey tones, giving it a professional and governmental feel.

US electricity demand is 𝐬𝐤𝐲𝐫𝐨𝐜𝐤𝐞𝐭𝐢𝐧𝐠 📈⚡ National 5-year forecasts for electricity load are 𝟓𝐗 𝐇𝐈𝐆𝐇𝐄𝐑 than previous predictions Peak demand is set to increase by 𝟏𝟐𝟖,𝟎𝟎𝟎,𝟎𝟎𝟎,𝟎𝟎𝟎 𝐰𝐚𝐭𝐭𝐬 by 2029 That's roughly 𝟏𝟑𝐗 peak demand for NYC today 🗽 This is behavioral, so, what's driving consumption? 🛒

Bar chart titled "U.S. electricity demand is expected to skyrocket after years of flat demand." It shows U.S. summer peak electric demand from 2016 to 2024 as historical data, and a projection for 2029. The demand remained relatively flat from 2016 (716 GW) to 2024 (745 GW). A sharp increase is projected in 2029, reaching 873 GW. The 2029 bar is divided into two colors: gray for 2024-level demand and orange for projected five-year load growth.

This requires fundamental reform: EU households face electrification barriers from taxation and levy policies. EU households pay 130% more taxes, fees, levies and charges for electricity than for gas per MWh.
