Sarah Williams, associate professor of Technology & Urban Planning at MIT, is a fan of sharing data. We are a fan of her book Data Action: Using Data for Public Good (published by MIT Press), a guide for working with data in more ethical and responsible ways. #OpenData #DataSharing

"So now, the question becomes, 'How do we actually make it so that these [data and tools] aren't just sitting in servers somewhere without people using them?" - Brittany Janis Grateful to be featured in @time.com , alongside some incredible collaborators in data pres! time.com/7344773/wome...

OpenAQ strives to make air quality data accessible to all, including people with disabilities. In this blog, our rockstar Medieinstitutet intern Maria Jonasson describes the work she undertook to audit and fix our site. link.openaq.org/a11y #a11y #WebAccessibility #DigitalAccessibility

EPA Administrator Zeldin's decision to stop considering the financial benefits of reducing asthma, heart disease, and premature deaths from soot and smog pollution is another reckless, dangerous attempt to deny the impacts of their polluters over people--and children--agenda. #ZeldinMustGo

OpenAQ has a new strategic plan. The heart of our work is to make #AirQuality data universally accessible. The soul is to engage with changemakers to provide the tools, training & leadership opportunities they need for data-driven #CleanAir action. See documents.openaq.org/strategy/Ope...

Among other takeaways in this spot-on report, Invest in Open Infrastructure found that "direct investment in open infrastructure delivers exceptional returns. Each dollar can enable anywhere from 2 to 50 times that amount in research activity that builds on or uses that infrastructure."

This #WorldChildrensDay, let's remember how important #CleanAir is for children. As pediatric infectious disease specialist Dr. Paul Lewis (Oregon, U.S.) stated, “Children are like hummingbirds; they breathe quickly and, for their size, end up with more #pollution in their lungs than adults.”

For the first time, #SoGA2025 includes air pollution's impact on dementia. Growing evidence suggests poor #AirQuality can progress and worsen neurological diseases - diminishing people's quality of life and causing premature death. @heisoga.bsky.social#SoGA2025#AirQuality Read the report: https://bit.ly/42PslPQ

This #AirQualityMonitoring project in Côte d’Ivoire, supported by the EPIC Air Quality Fund, has an innovative approach: deploying sensors at pharmacies to ensure consistent power & increased security (and because pharmacists are trusted messengers). link.openaq.org/AQ54 #AirPollution #DataforGood

#ThrowbackThursday! Winter 2016 - 12 OpenAQ Community members from 10 countries + anonymous co-authors shared OpenAQ’s view on the importance & power of open air quality data in the Clean Air Journal. "To combat air inequality, governments & researchers must open their data." bit.ly/48R7vDu

Visualising historical changes in air pollution with the Air Quality Stripes Website: airqualitystripes.info And paper led by @kirstypringle.bsky.social and @jimmcquaid.bsky.social now published which visualises trends in air quality across many global cities: gc.copernicus.org/articles/8/2...

Some good news. London is meeting legal limits for toxic NO2 pollution for the first time – almost 200 years earlier than predicted – following the Mayor’s "world leading air pollution policies," City Hall announces. The Ultra Low Emissions Zone - and similar policies - really do work.

Throwback Thursday! In this blog from 2016 we describe the difference between “open data” and “open-source.” Read "Is That ‘PM2.5’ on Your Grocery Store List?" at openaq.medium.com/is-that-pm2-...

#ThrowbackThursday! In one of our very first blogs, 10 years ago, OpenAQ made the statement below. Has OpenAQ played a transformational role in YOUR use of #AirQuality data? Read "Filling The Air Quality Data Gap" at link.openaq.org/aq-data-gap

99% of people breathe air that’s considered polluted. 😷 It damages health, lowers crop yields, deepens inequality and fuels climate change. For this #CleanAirDay, here are 10 things you should know about air pollution and what can be done about it: www.unep.org/news-and-sto...

What are the latest trends in air pollution, where is it worst, and how is forecasting improving? Released for #CleanAirDay, @wmo-global.bsky.social’s latest Air Quality and Climate Bulletin 2025 has the answers: bit.ly/4gho8Ki

We'll be here! Let's meet up during Climate Week!
