Thinking Bigly has changed with the year.  The conversation around flying has changed. My points about hand dryers have come to life.

 Hand dryers are moderately better than paper towels in terms of life cycle energy and waste use, but are significantly worse in maintaining strong hygiene. Partly as people don’t use them properly and partly as the air blows droplets around. Some of them are also too noisy for children’s ears.  But paper towels have more waste and have a higher life cycle carbon footprint. 

Another change is China.  The Chinese have now committed to net zero in 2060. This is a significant new message announced in the last few weeks.
