Is Manchester doing enough to fight its air pollution crisis?

In June 2018, think tank IPPR released a report calling Greater Manchester’s pollution levels “lethal and illegal”. The report called on mayor Andy Burnham to urgently ramp up measures to improve air quality and for central government to give him the tools to do so.

Yet one year on, the Northern Quarter Forum has had to fight tooth and nail to close Stevenson Square to traffic for just five hours to celebrate Clean Air Week. This, coupled with the Great Ancoats Street fiasco – a multi-million pound plan to create a “European style boulevard” without any cycle infrastructure – raises red flags.

So what’s actually being done to fight Manchester’s air pollution crisis – and is it enough?

An ambitious pledge

Andy Burnham has pledged to make Manchester a leading green city in Europe. It’s an ambitious goal, considering central Manchester currently has the highest rate of emergency admissions for asthma in England – over double the national average – and Manchester is the second-worst council area in England for inhalable particulate matter. Greater Manchester is also the most congested region outside of London, with 152 roads in breach of legal NO2 levels.

All in all, 1,200 lives are lost each year due to air pollution. If that number is to be brought down to zero, Manchester better look for inspiration.

Oslo, European Green Capital 2019, prioritises pedestrians and cyclists in the city centre, and is transitioning to a completely car-free city centre. All public transport will run on renewable energy from 2020, and over 700 on-street parking spaces were removed, replaced with cycle lanes, pocket parks, and seating areas. Since the 1980’s Oslo has had tolled ring roads, and in 2017 introduced a further congestion charge.

The message is clear: becoming a leading green city means reducing the number of vehicles on the road. Switching to electric cars won’t be enough to save us, because worn tyres and brakes produce particulate matter, the micro plastic particles penetrating the deepest parts of our lungs and bloodstream.

What’s required, instead, is improved public transport – currently often both less convenient and more expensive than driving – as well as prioritising walking and cycling.

So with Burnham’s ambitious – and worthy – pledge in mind, let’s see what Manchester is doing.

Is enough being invested in public transport?

Last year, Burnham revealed his “Congestion Deal”, which includes a £122m Bus Priority Package (shepherding 9,000 more passengers a week) and spending £83m on 27 new trams. The deal also commits 40,000 more seats on commuter trains, and trebles the number of electric vehicle charging points in the region to 1,000.

Manchester’s Clean Air Plan also includes £116m government funded schemes for HGV’s, buses, taxis, and businesses upgrading to cleaner vehicles, as well as loans with preferential rates for those taking advantage of the funds.

While that may look like a lot of investment, it pales in comparison to the nearly £6bn being considered on road schemes. Moreover, research has repeatedly shown the benefits of road expansion are short-lived, “inducing” more car journeys leading to increased congestion and pollution overall.

The biggest cue for public transport in Manchester is Burnham’s recent proposal to franchise buses, bringing them back under public control. This will allow GMCA to develop a truly integrated public transport system and ensure all communities are served, not just those that are most profitable. It will also allow them to set the fares, bringing them in line with those in London; whereas it costs £4 in Greater Manchester for a single bus fare, the rate is currently capped at £1.50 in the capital.

That being said, there’s still a pressing need for more funding. When I asked the Clean Air Plan folk at Transport for Greater Manchester (TfGM) what’s the one thing government could do to help, they told me this: “To agree a devolved multi-year transport funding settlement with Greater Manchester” that includes ongoing funding, “to help us to transform public transport services to meet modern expectations as people experience in other cities across Europe.”

Despite the progress being made, as long as central government doesn’t provide new funds – and the bulk of existing funding is pumped into motorways instead – Manchester won’t become a leading green city.


Is walking and cycling being prioritised?

Burnham’s Congestion Deal also outlined a “Streets for All” approach, in which streets would be designed “for all road users” to enable alternatives to driving.

Chris Boardman became Greater Manchester’s first Walking and Cycling Commissioner in 2017 with an initial £160m earmarked to begin creating “Bee Network” safe cycle routes throughout the city – making Manchester a truly European city. That funding has now been allocated, and the first projects are coming to fruition.

However, it only accounts for 11 per cent of the £1.5bn needed to complete the Bee Network, and Boardman along with five other leading cycling commissioners are demanding government commit long-term funding to safe cycle infrastructure.

Boardman calls painted bike lanes a “waste of public money”, which encourage drivers to speed up, endangering cyclists. “Actual” bike infrastructure is needed, such as segregated cycle lanes.

He’s pointed out that government has recently agreed to spend £1.4bn on upgrading a roundabout near Bedford and building a new 10-mile dual carriageway – two projects that together may save drivers 10 minutes of travel. For the same price, Manchester could have a fully integrated cycle network that would revolutionise the way people travel around the city. Central and local government simply aren’t prioritising the measures needed to reduce air pollution.

That’s why Manchester City Council’s announcement of the £9.1m “Great Ancoats Street improvement scheme” – maintaining five lanes of motor traffic with no cycle infrastructure along one of the city’s most polluted and dangerous thoroughfares – has provoked anger and despair.

The council’s justification – “This scheme does not incorporate a segregated cycleway, as we need to balance the needs of different road users” – Illustrates a business-as-usual mindset of car dominated planning. It’s completely at odds with the scale of the challenge Manchester faces in turning around its air quality crisis.

There’s also a long way to go towards prioritising walking and cycling in the city centre. When Manchester City Council refused permission to close Stevenson Square to traffic for just five hours for the community to celebrate Clean Air Week, Northern Quarter Forum members took matters into their own hands.

They developed a plan to reroute the 13 buses that traverse Lever Street and presented it to the Highways department (essentially having done their job for them). Then it was actually Labour party councillor Angeliki Stogia who took the reins and pushed the request through.

Apart from Stogia, this lack of support for a resident’s group advancing what should be the council’s agenda is troubling. This, along with Great Ancoats Street, suggests a council not taking a “Streets for All” approach seriously, wand lacks the will to prioritise alternatives to driving in the city centre.

Is a congestion charge being introduced?

In the past year, the main focus has been developing a “Clean Air Zone”, covering all of Greater Manchester. The scheme would charge the most polluting buses, taxis, heavy and lights goods vehicles entering the zone.

This Clean Air Zone isn’t a congestion charge because it doesn’t charge polluting private vehicles. However, congestion charges are shown to be highly effective.

When Stockholm introduced its congestion charge 11 years ago, it was dubbed “the most expensive way ever devised to commit political suicide.” The charge began with just 25 per cent public approval – but when congestion dropped by 20 per cent, public opinion changed rapidly. After a seven month trial period, a referendum made the scheme permanent, and public approval now stands near 70 per cent. Revenue from the scheme has funded new metro lines and active travel improvements.

TfGM argue that charging private cars will hurt the poorest in society. However, ONS data show that while nearly all households in the richest 10 per cent by income own a car, just a third of those in the lowest 10 per cent own one. And nearly all homeowners have at least one car, compared to less than half of households in social housing.

In reality, households on lower incomes are far more likely to rely on public transport, and are disproportionately impacted by poor air quality.

The elephant in the room: the airport

Burnham has pledged to make Greater Manchester carbon neutral by 2038.

It’s difficult to imagine how this is possible, considering that Manchester Airport – 65 per cent owned by Manchester City Council – is expanding. Over the next 20 years, it plans to double passenger numbers.

Globally, aviation emissions are growing so quickly that by 2020 they’re projected to be 70 per cent higher than in 2005 and are currently 26 per cent higher than in 2013. If it were a country, global aviation emissions would be within the top 10 emitters. Here in Manchester, Pete Abel of Manchester Friends of the Earth says the current airport expansion plans would blow “our carbon budget twice over”.

A lack of follow-through

The stakes are high, the consequences dire. Strong, decisive action is required to rid Manchester of its poisonous air.

While Burnham has the vision, he doesn’t have the power. Without buy-in and consistent action from the 10 councils as well as central government, there’s only so much that can be accomplished – and it won’t be enough.

Public transport must become convenient and cheaper than driving. All city streets must enable walking and cycling. Mancunians – as well as city dwellers around the country – must hold elected representatives to account, let them know "business as usual" is no longer acceptable, and demand action to match the rhetoric.

Green roofs improve cities – so why don’t all buildings have them?

Rooftops covered with grass, vegetable gardens and lush foliage are now a common sight in many cities around the world. More and more private companies and city authorities are investing in green roofs, drawn to their wide-ranging benefits which include savings on energy costs, mitigating the risk from floods, creating habitats for urban wildlife, tackling air pollution and urban heat and even producing food.

A recent report in the UK suggested that the green roof market there is expanding at a rate of 17 per cent each year. The world’s largest rooftop farm will open in Paris in 2020, superseding similar schemes in New York City and Chicago. Stuttgart, in Germany, is thought of as “the green roof capital of Europe”, while Singapore is even installing green roofs on buses.

These increasingly radical urban designs can help cities adapt to the monumental challenges they face, such as access to resources and a lack of green space due to development. But buy-in from city authorities, businesses and other institutions is crucial to ensuring their success – as is research investigating different options to suit the variety of rooftop spaces found in cities.

A growing trend

The UK is relatively new to developing green roofs, and governments and institutions are playing a major role in spreading the practice. London is home to much of the UK’s green roof market, mainly due to forward-thinking policies such as the 2008 London Plan, which paved the way to more than double the area of green roofs in the capital.

Although London has led the way, there are now “living labs” at the Universities of Sheffield and Salford which are helping to establish the precedent elsewhere. The IGNITION project – led by the Greater Manchester Combined Authority – involves the development of a living lab at the University of Salford, with the aim of uncovering ways to convince developers and investors to adopt green roofs.

Ongoing research is showcasing how green roofs can integrate with living walls and sustainable drainage systems on the ground, such as street trees, to better manage water and make the built environment more sustainable.

Research is also demonstrating the social value of green roofs. Doctors are increasingly prescribing time spent gardening outdoors for patients dealiong with anxiety and depression. And research has found that access to even the most basic green spaces can provide a better quality of life for dementia sufferers and help prevent obesity.

In North America, green roofs have become mainstream, with a wide array of expansive, accessible and food-producing roofs installed in buildings. Again, city leaders and authorities have helped push the movement forward – only recently, San Francisco created a policy requiring new buildings to have green roofs. Toronto has policies dating from the 1990s, encouraging the development of urban farms on rooftops.

These countries also benefit from having newer buildings, which make it easier to install green roofs. Being able to store and distribute water right across the rooftop is crucial to maintaining the plants on any green roof – especially on “edible roofs” which farm fruit and vegetables. And it’s much easier to create this capacity in newer buildings, which can typically hold greater weight, than retro-fit old ones. Having a stronger roof also makes it easier to grow a greater variety of plants, since the soil can be deeper.


The new normal?

For green roofs to become the norm for new developments, there needs to be buy-in from public authorities and private actors. Those responsible for maintaining buildings may have to acquire new skills, such as landscaping, and in some cases volunteers may be needed to help out. Other considerations include installing drainage paths, meeting health and safety requirements and perhaps allowing access for the public, as well as planning restrictions and disruption from regular ativities in and around the buildings during installation.

To convince investors and developers that installing green roofs is worthwhile, economic arguments are still the most important. The term “natural capital” has been developed to explain the economic value of nature; for example, measuring the money saved by installing natural solutions to protect against flood damage, adapt to climate change or help people lead healthier and happier lives.

As the expertise about green roofs grows, official standards have been developed to ensure that they are designed, built and maintained properly, and function well. Improvements in the science and technology underpinning green roof development have also led to new variations on the concept.

For example, “blue roofs” increase the capacity of buildings to hold water over longer periods of time, rather than drain away quickly – crucial in times of heavier rainfall. There are also combinations of green roofs with solar panels, and “brown roofs” which are wilder in nature and maximise biodiversity.

If the trend continues, it could create new jobs and a more vibrant and sustainable local food economy – alongside many other benefits. There are still barriers to overcome, but the evidence so far indicates that green roofs have the potential to transform cities and help them function sustainably long into the future. The success stories need to be studied and replicated elsewhere, to make green, blue, brown and food-producing roofs the norm in cities around the world.
