Sustainability Week: The first three days

February 8, 2017 /

With Sustainability Week now in full swing, it is time to recap what happened so far, and what events you can still get involved in.

We asked students what they would do if they were Principal for the day

On Monday and Tuesday we took over the space outside the Great Hall at Strand with our Sustainability Roadshow. Representatives from King’s Money Mentors, Hubbub, Veolia, Thames Plastic, RSPB, EcoSoc, Abe & Cole and Amey joined us for this, and we got the chance to chat to students about sustainability at King’s. Among other things, such as our popular recycling game, we asked students to write down what they would do if they were Principal of King’s for a day. Ideas included switching to clean energy, providing recycling training and banning non-recyclable coffee cups. We will take this feedback and see what we can do about these suggestions to make King’s more sustainable!

Highlights of other events include our Vegfest, which saw around 100 students try plant-based food (including Sheese!). We also held a bike auction at Strand, during which 16 second-hand bikes found new homes. Dr Bike were also on site to provide bike checks, and will travel with us to the other campuses over the next two days. King’s Careers & Employability ran two successful events on how to start a career in the sustainability sector, giving students the chance to ask sustainability professionals for advice.

If you have missed our events so far, you still have the chance to take part! Sustainability Week lasts until Friday the 10th February, and there are still lots of events coming up.

Tonight, there will be a panel debate on whether overconsumption or overpopulation is the biggest problem we face.

On Thursday, we will take our Sustainability Roadshow to Waterloo Campus. There will also be a Clothes Swap Shop at Waterloo in the morning. In the evening, you can attend a free screening of Tomorrow (2015), or pitch your idea on how to make King’s more sustainable at the Geography Department’s Sustainability Challenge.

Finally, on Friday we move to Denmark Hill for a seminar on why healthcare professionals should care about climate change, and we will bring our Roadshow, bike fixing sessions and Clothes Swap Show with us.

For more information, check out the full schedule here. We are looking forward to seeing you at the remaining events!

“Space to Breathe” at Somerset House

January 31, 2017 /

Last weekend, visitors to Somerset House could enjoy a series of interactive installations around the topic of air pollution. Pollution in London regularly exceeds legal limits, often due to the heavy traffic. The Space to Breathe exhibition aimed to raise awareness of this important issue by making it accessible to people.

BackPack2SmallThe exhibition was curated by Cape Farewell and Shrinking Space, in partnership with the Environmental Research Group (ERG) here at King’s College London. The ERG also run the LondonAir website, giving Londoners up-to-date information about the air we are breathing on a daily basis.

Wearing the “Voyage on the Planet” backpack

One of the most striking pieces of the exhibition was Chih Chiu’s “Voyage on the Planet”: a glass backpack with a plant inside, connected to a facemask to block out surrounding pollution. Visitors were encouraged to try it out themselves, and to take it outside to the streets of London. Cape Farewell and Shrinking Space posted photos of this throughout the weekend. I also got the chance to try one of the backpacks, which did make me think about what I breathe in every day – even when just crossing Waterloo Bridge!

CycleSmall

Cycling to run the bar

By using VR headsets, the exhibition also offered to experience what the Aldwych could look like in a greener future: think lorries and cars replaced by pedestrians and green space. Artist Caroline Wright asked people to sing a single note to see how where they live affects their lung volume, and to collate the voices of visitors in a single Sounding Scape. On the Terrace, Solar Sound System ran a bar powered on solar energy and bicycles: two people cycle to keep the music on, while to more cycle to get the juice presses working.

Air pollution is something that is largely invisible, especially when it comes to NO₂. Throughout the weekend, the artists and experts at Space to Breathe made it visible through the different installations. Photos of the whole weekend can be found by visiting Cape Farewell, Shrinking Space, Cultural King’s and LondonAir.

Part 3 of 3: What can I do about air pollution?

November 21, 2016 /

Welcome back to our series on air quality! In previous posts, we focused on why pollution matters and what the main causes are in London. In this final part, Timothy Baker from the Environmental Research Group (ERG) at King’s offers his advice on how individuals can protect themselves from pollution, and what they can do to help clean up London’s air.

Living in London, we are exposed to varying levels of pollution every day. As Tim Baker discussed in the first part of this series, the places where we are most exposed might be surprising – such as inside our cars or taxis. Although walking or cycling may be better for our health than being inside a car, we are still exposed to pollution. We asked Tim Baker what the method for reducing this exposure was, and he suggested planning routes carefully:

“It’s actually all common sense. If you avoid the traffic when walking or cycling somewhere, you will dramatically reduce your exposure levels. Even just going one street back from the main road will probably halve your pollution exposure. It’s as simple as that.”

To make this easier, the ERG’s London Air website offe_DSC6991rs street-by-street pollution maps, enabling Londoners to plan a route avoiding the most polluted areas. The team is also planning a mapping service that would automatically give users the least polluted route to their destination. Those most at risk, such as people suffering from existing respiratory problems, should check pollution forecasts before undertaking strenuous tasks outside, and potentially wait if pollution is expected to clear later in the day.

There is also a range of things our expert Tim Baker believes individuals can do to contribute to tackling pollution in London. As a large proportion of pollution is due to transport, the first step is not using a car to get around the city. Cycling or walking to work would reduce traffic, often get people to their destination quicker, and even though cyclists are exposed to pollution, Tim Baker claims the health benefits of cycling offset the risk of exposure. Another option is to take public transport. Responding to a recent initiative to publish air quality data on polluted days at bus stops, the expert welcomed the idea and said:

“At the end of the [air quality] message they should add ‘Thank you for doing something to help’. Because if someone sees it at a bus stop, they are already helping the problem by using public transport.”

If driving is necessary, people should think carefully about what kind of cars to get.
While cars powered by alternative fuels may be more environmentally friendly than those powered by petrol or diesel, they are still expensive. Engine size should also be kept in mind. “If you’re looking for what is going to have the least impact [on air quality], and is a cheap vehicle, it’s probably currently going to be a small petrol engine”, says Tim Baker. Finally, something that King’s, businesses and even households should reconsider is the necessity of having items delivered as soon as possible. Many deliveries are not required immediately, and instructing companies to wait until several items can be delivered at once is an easy way to reduce traffic on the roads. At London Bridge, local businesses suggested to have consolidated deliveries at night, and have campaigned to keep their streets pedestrianised during the day. As more and more businesses get involved and even help fund measuring equipment, the expert says everybody else will hopefully follow soon to help combat pollution in London.

We would like to thank Timothy Baker for taking the time to answer our questions and share his advice with us.

Part 2 of 3: The causes of London’s pollution problem

November 14, 2016 /

Welcome back to our series on air quality! Last time, we talked about why air pollution matters. Today, the focus will be on the main causes of air pollution in London – and why the Volkswagen emissions scandal might have had some positive consequences after all. Again, Timothy Baker from the Environmental Research Group (ERG) at King’s has shared his knowledge with us, and given us his expert view on what governments should do to tackle pollution. 

When it comes to the causes of pollution, many might be quick to blame large vehicles such as lorries. But according to Tim Baker, one of the main culprits for air pollution in London are diesel cars. They were often seen as the more environmentally friendly option compared to petrol cars, but while technology in petrol has improved rapidly in recent years, diesel cars have lagged behind. “The Department for Transport tested the 15 most popular diesel vehicles, and on average they were 4 to 7 times over the legal limit”, says Tim Baker in our interview. Petrol cars on the other hand only achieve somewhere around 10% of the emissions they are legally allowed to achieve, he claims. ITF066044RGB75Under certain conditions, many diesel cars will also switch off their emission controls. Legal loopholes enabled them to do this when the outside temperature falls below 18°C. While manufacturers claim this is to protect the engine, average temperatures in London mean this causes significant problems for the city’s pollution levels, as cold periods are often when pollution builds up. This is made worse by the rising number of diesel vehicles on London’s roads.

“What we have seen is that the advances in technology in some vehicles have been massively offset by the change in fleet, especially in London. 10 years ago, probably around 15% of cars on the road were diesel. The year before last, more than half of the registered new cars were diesel.”

Some weather conditions can also contribute to higher pollution levels. Pollution can build up when it is not windy, and some of the worst pollution episodes happen on cold, foggy mornings when pollutants are trapped close to the ground. In addition to this, London’s geographical location means it may also be exposed to pollution from continental Europe. This is usually the case during spring, when wind carries pollution from the Netherlands, Belgium or France to London. However, the opposite is true for large parts of the year, carrying emissions from South East England to continental Europe. IND053Therefore, even local pollution might require cross-border efforts to be tackled effectively. “It’s also someone else’s local emissions. And where are our local emissions going when they are not causing us a problem? They are going to somebody else”, says Tim Baker.

To solve London’s pollution problem, he says governments need to be brave, and not afraid to make difficult decisions. “Everyone says it’s the lorries. But if you actually want to solve the urban pollution problem in London, in a stroke, it’s ban diesel cars”, Tim Baker tells us in the interview. While this might be a drastic measure, he believes the public is now more aware of just how bad diesel vehicles are for air quality. “The Volkswagen emissions scandal did more for publicity than anything that has been done in the previous years of trying to get the story across”, the expert tells us, explaining that when the first London sites exceeded annual limits earlier this year, the press coverage had changed compared to previous years. “Usually they are calling us to explain why air pollution is bad for you. That didn’t happen this time – they actually started their articles with ‘We know air pollution is bad for you, it’s diesel that is causing it’.” As much of the changes to London’s car fleet have happened in the last 10 years, Tim Baker believes these changes should be reversible over the next 10 years. However, he is not sure governments are ready to do this:

“Is it likely to happen? Probably not. It should be possible, but I suspect there isn’t the bravery. I hope I’m proved wrong”

1917496_212679981259_3444746_nThe next and final part of our air pollution series will focus on the actions each individual can take to both protect themselves from pollution, and to help clean up London’s air. In the meantime, you can follow us on Twitter and Facebook for more updates, as well as the ERG’s Twitter and website for regular pollution updates and forecasts.
