Another thumping good read dropped onto the doormat this morning in the shape of New Civil Engineer magazine. The problem of air pollution is brought into sharp focus by an OECD graph which shows that air pollution currently accounts for 3 million premature deaths globally every year, with that set to rise to 9 million by the year 2060. The EU and Russia are the only regions charted which show a significant fall in predicted air pollution deaths, whilst India and China deaths are predicted to more than double.
Another chart shows that UK CO2 emissions arising from power generation have fallen from 180 metric tonnes in 2005 to 100 metric tonnes in 2015. However transport hasn’t improved, with 130 Mt in 2005 and 130 Mt in 2015. So it is not surprising that other articles focus on how transport can be made greener.
There is an interesting piece on aviation with an eye-catching photo of a blended wing aircraft being developed by Boeing and NASA. The idea seems to be that by making the aircraft virtually all wing, and putting the seats in the wing, you end up with something much more efficient. Other, perhaps less ambitious developments, include making the drink and food carts lighter as well as other items like seats.
Of course we don’t have to be aircraft engineers to save a life. We can avoid unnecessary car journeys by walking or cycling where possible. Apparently just 20 minutes brisk walking a day brings us significant health benefits, yet only a third of Londoners report achieving this much activity. In Scotland physical inactivity results in 2,500 premature deaths a year, seven a day. There is a great article describing how we can make our city streets more pedestrian friendly through simple things like de-cluttering pavements to remove extraneous signs, improving crossings, providing seating and public toilets on walking routes.
I checked the front cover, when I wondered if I was the victim of an April fool story, but no, putting cat litter into concrete really is a way to cut CO2 emissions. There is a Bath University research project showing that the absorbent granules present in cat litter can be used to carry a material which can absorb or release heat depending on temperature, thereby helping to keep a building at a constant temperature.
In the editorial, civil engineers are asked to open their (our) minds and learn more quickly what people need; to be focussed on outcomes rather than outputs. Sounds like Project Sponsorship to me.
