While the Government delays, cities are taking radical steps to cut carbon

Cities are where the biggest experiments can take place; look to them to see the future of the UK.

Our cities are the R&D facility for the country. From 4G rollout to community energy, they let us experiment with what’s possible. This is useful, because we’ve just agreed to change everything. The recent Energy Bill accepts how inevitable a low carbon future is for the UK. It also guarantees the money to deliver it on time – all we have to do now is actually do it.

Of course, some don’t seem to realise this. Some ministers hang desperately onto a gas over renewables strategy, like a hipster to a mini disc player, convinced its time will come again. No evidence will dissuade them back into reality. This wouldn’t be a problem, but the indecision and delay they introduce makes it harder to ensure that the UK will get the maximum benefit from a low carbon future – to own the patents, build the factories and get exporting to the others following behind. Luckily, we don’t need to wait for national government to get its story straight, because our cities are set to leap ahead.

A city has traditionally been something that demands a lot from a country and gives back money and jobs. London has around the same working population as Scotland, Wales and Northern Ireland put together, and so it soaks up more electricity than any of those nations. Without freight coming in from the rest of the world, it would run out of food in four days. Sure, cities pay for this stuff, but it’s the rest of the country that has put up with its infrastructure: the power stations, water reservoirs, and industrial waste facilities all put into the countryside to serve the cities. However, this is changing.

The density of the population and the buildings make for a unique testing ground for the new kind of infrastructure we’re developing - the low carbon, resource efficient approaches to heating and power generation, transport and waste management. They all work best if done where the demand is greatest, and that means at the city scale.

This is what Green Alliance’s new report argues – cities are morphing themselves and what they do ahead of the rest of the country and they are well placed to get the economic reward for doing so. The recent city deals process, initiated by the Cabinet Office transfers new powers, control over funding and approaches to financing to the cities. The first eight cities have thought about what this means to reverse employment trends and attract inward investment which is why most have used their deals to grow their low carbon economy.

Newcastle is going for £0.5bn of investment in offshore energy, bringing eight thousand jobs. Liverpool plans to accelerate £100m in wind and offshore energy, bringing three thousand jobs to the area. Manchester is using its ambitious emissions reduction targets to attract an additional £1.4bn into the UK’s economy and Birmingham has secured a £3m injection to its housing retrofit programme.

Many of these projects, which are central to how our country will work in the future, are already real in the cities. London will have 1,300 different electric vehicle charging points by next year and, in the capital, a Prius seems a more common sight that an Escort. Islington is rolling out council-owned Combined Heat and Power to 700 homes, a power station set up not miles away, but amongst the people that will benefit, protecting them from soaring bills. Meanwhile, Birmingham council is doing the same, trying to reduce the energy it imports every year at a cost of £1.5bn and replace it with energy they make themselves. In the centre of the city, on Broad Street, Birmingham’s CHP serves the ICC, the town hall, the new library and local hotels and theatres. Nottingham too, aims to double its district heating network in five years.

This is where the future is happening. It proves that green infrastructure is the model that keeps costs down for the public and profits up for businesses. All we need now is for Westminster government to realise this. As it plans a big push on renewing our national infrastructure, it should learn from and work with our cities, who are demonstrating that a modern, sustainable approach, employing ideas that reduce energy, reuse waste and simplify our public transport, will bring the biggest rewards.

#Match4Lara: Lara has found her match, but the search for mixed-race donors isn't over

A UK blood cancer charity has seen an "unprecedented spike" in donors from mixed race and ethnic minority backgrounds since the campaign started. 

Lara Casalotti, the 24-year-old known round the world for her family's race to find her a stem cell donor, has found her match. As long as all goes ahead as planned, she will undergo a transplant in March.

Casalotti was diagnosed with acute myeloid leukaemia in December, and doctors predicted that she would need a stem cell transplant by April. As I wrote a few weeks ago, her Thai-Italian heritage was a stumbling block, both thanks to biology (successful donors tend to fit your racial profile), and the fact that mixed-race people only make up around 3 per cent of international stem cell registries. The number of non-mixed minorities is also relatively low. 

That's why Casalotti's family launched a high profile campaign in the US, Thailand, Italy and the US to encourage more people - especially those from mixed or minority backgrounds - to register. It worked: the family estimates that upwards of 20,000 people have signed up through the campaign in less than a month.

Anthony Nolan, the blood cancer charity, also reported an "unprecedented spike" of donors from black, Asian, ethcnic minority or mixed race backgrounds. At certain points in the campaign over half of those signing up were from these groups, the highest proportion ever seen by the charity. 

Interestingly, it's not particularly likely that the campaign found Casalotti her match. Patient confidentiality regulations protect the nationality and identity of the donor, but Emily Rosselli from Anthony Nolan tells me that most patients don't find their donors through individual campaigns: 

 It’s usually unlikely that an individual finds their own match through their own campaign purely because there are tens of thousands of tissue types out there and hundreds of people around the world joining donor registers every day (which currently stand at 26 million).

Though we can't know for sure, it's more likely that Casalotti's campaign will help scores of people from these backgrounds in future, as it has (and may continue to) increased donations from much-needed groups. To that end, the Match4Lara campaign is continuing: the family has said that drives and events over the next few weeks will go ahead. 

You can sign up to the registry in your country via the Match4Lara website here.
