Opinion: Any #Technology can be judged by how helpful it could have been for ordinary people pre-1900s. I picked the period for the overlap of being after the Industrial Revolution, but before Henry Ford drowned us in cars. Any technology of minimal or no help to people back then can be challenged.
A local authority said it was on track to meet the previous 30 µg/m³ limit (set in 2021) by the end of this year. The Oxford City Council stated its priorities for 2026-2030 were on continuing the reduction of transport emissions. Examples include traffic filters and expanding the ZEZ.

Excellent to hear that @oxfordcitycouncil.bsky.social is reinforcing its commitment to clean air by adopting the interim @who.int target for nitrogen dioxide of 20 µg/m³ by 2030.

We're looking forward to a very clear commitment to the same from @london.gov.uk. #AirPollution #Health

The upgrade entails enhanced treatment capacity, resilience, solar panels, daylighting, LED lighting controls, an odour control system, a best-in-class grit washing & dewatering system and a vertically designed layout that conserves space.

Good read. #AirQuality is a multi-faceted problem. Namely that new 2.5 micron Particulate Matter can form from gaseous pollutants like SOx, NOx & ammonia emissions. Also, the problem has to be tackled at the regional level, because air pollutants emitted from far away can still become your problem.

🌬️ High indoor CO₂ = poor ventilation = higher COVID risk.

We breathe out both CO₂ and viral aerosols when the air’s stale, viruses can linger.

💡 Keep CO₂ under 800 ppm, open windows, and use purifiers.

"As of November 2024, the pollution index exceeded 500 points, forcing the temporary closure of schools, construction sites, and factories."

Causes mentioned include stubble burning, Diwali festival fireworks and urban emissions.

"The Rapide 3 itself is capable of top speeds of 80 km/h and has a range of up to 180km on a single charge. In terms of capacity, it can hold 150 small parcels (or 200kg) – which [...] is a 400 per cent increase in capacity over its outgoing Honda motorbikes."

Fascinating study. Note that this is 1 in 10 adults. Factor in children and the percentage of non-driving Americans is much higher. Cities and towns need to account for their mobility needs too.
1 in 10 Americans rarely or never drive a car
Among U.S. adults, those who live in the Northeast (17%) are more likely than those in the South (10%), West (8%) and Midwest (7%) to be nondrivers.

With living conditions, better resilience often means some sacrifices or idle potential, even with good management. Is it more comfortable to live in better conditions that is more likely to collapse than in more humble conditions you could depend in the face of disturbances or black swan events?
Aside from electric vehicles, batteries are increasingly becoming a viable pick for storing solar energy for peak demand periods. Europe would do well to do more onshoring or friend-shoring of supply chains for such an increasingly critical technology.
