Clearing the Air - Bloomsbury

[Pre-order now] Whilst living in London, sustainability journalist Tim Smedley became concerned by the escalating headlines regarding air pollution levels, and also by how little he knew about it. Outdoor air pollution was shortening his life – and potentially that of his young family – and yet he, and the city around him, carried on oblivious. In a bid to understand more, he travelled to several major world cities dealing with severe air pollution problems, including Delhi, Beijing and Paris, to speak to the scientists and politicians leading the fight against air pollution, and to the people whose lives have been affected by it...

The outrageous plan to haul icebergs to Africa

If towing icebergs to hot, water-stressed regions sounds totally crazy to you, then consider this: the volume of water that breaks off Antarctica as icebergs each year is greater than the total global consumption of freshwater. And that stat doesn’t even include Arctic ice. This is pure freshwater, effectively wasted as it melts into the sea and contributes to rising sea levels. Does it sound less crazy now? This untapped flow of water has enticed scientists and entrepreneurs for over a century...

How to drink from the air

All air, from arid deserts to humid cities, contains water vapour – globally, an estimated 3,100 cubic miles (12,900 cubic kilometres) of water is suspended as humidity in the air around us. That’s five Lake Victoria’s (Africa’s great lake, at 2,700 cubic km). Or a whopping 418 times the volume of Loch Ness. But we’re not talking about clouds. This is the humidity in the air we breathe, that reappears as beads of water on the side of a cold drink, or as morning dew on blades of grass. And a technological race is underway to harvest it as drinking water. If the emerging ‘water from air’ (WFA) devices can crack it, it could go a long way towards solving the world’s freshwater problem.

Air pollution investigation by environmental journalist Tim Smedley in "major" acquisition by Bloomsbury Sigma

Bloomsbury Sigma has signed Clearing the Air by environmental journalist Tim Smedley in a "major" acquisition for the imprint. Jim Martin, publisher at Bloomsbury Sigma, acquired world rights to Smedley's Clearing the Air: The Beginning and the End of Air Pollution from Jenny Hewson of RCW Literary Agency. The title will investigate what pollutants are in the air, "what they do to us" and "what we can do about it". Smedley said: "Air pollution is on everyone's minds right now, with a backlash...

Public speaking fear is limiting your career

Glen Savage is about to go on stage wearing wings and a halo. He’s terrified. The year is 1961 and the five-year old Savage is playing the Archangel Gabriel in the nativity play at St James School in Brisbane, Australia. He has just one line: “Come here baby angels”. Little did he know then, but the fear and anxiety of that moment would go on to shape his entire career. “I just remember thinking that I can’t do it. I can’t speak in front of all those people”, Savage recalls. “I was absolutely

How the world’s biggest cities are fighting smog

For three days in March 2016, 10 London pigeons became famous. Seeing pigeons take to the sky from Primrose Hill in north London was not unusual in itself. But these pigeons were wearing backpacks. And the backpacks were monitoring air pollution. Once in the air, the backpacks sent live air-quality updates via tweets to the smartphones of the Londoners below. In almost all cases, the readings were not good. London’s air pollution problem has been getting worse for years, and it often rises to more than three times the European Union’s legal limit.

Why young Londoners are moving to houseboats

Many Londoners would be envious of the postcodes Matthew Winters has lived in: the likes of Broadway Market, Angel, Camden, and Little Venice are amongst the city’s most hip and expensive. Many more would covet his electricity bill: £600 ($754) for the next 15 years. How, then, is he only 24 and a resident of London for just two years? Winters, an actor, is part of a booming trend for houseboat living among young Londoners. And specifically for what’s known as a ‘continuous cruising’ (or ‘CC-in

The bank boss with an environmentalist bent

Despite becoming the UK’s managing director of Triodos bank this spring, Bevis Watts maintains that he is “first and foremost an environmentalist”. Triodos’s mission is to lend money only to those who promote “positive social, environmental and cultural change”. The Dutch bank, which has €12bn of assets under management, is part of a booming trend. In 2015, the responsible lending market in the UK grew 45 per cent, according to a report by the Community Development Finance Association and PwC. Mr Watts’s CV does not read like that of the average bank executive...

Careers you thought paid megabucks

We all know the type. The architects, property moguls and professors, who drive flashy cars and shower themselves with bank notes. Except the truth is, we only think we know their type. Our image of how much others are earning often doesn’t match the reality. While many professionals bring home above the national average wage, are they really as wealthy as we think given the years of student loans they rack up? BBC Capital set out to investigate...

Why leaders ignore new technology at their peril

Business leaders used to get by without knowing much about technology – they had an IT department to deal with that sort of thing. However, technology products and services now pervade every industry, and businesses that don’t understand them are in danger of being usurped. Uber’s impact on the taxi and automotive industries is a case in point. While established manufacturers and car hire firms continued to focus on hardware – the cars and the user experience – Uber’s simple software app linked...

Developing countries lead in clean energy

Renewable energy used to be deemed unaffordable for developing countries. Wind and solar were rich country luxuries, while 'third world' economies could only be expected to grow on a diet of dirty fossil fuels. As recently as June 2014, Bill Gates blogged: “Poor countries… can’t afford today’s expensive clean energy solutions and we can’t expect them to wait for the technology to get cheaper.” However, the past two years have seen this received wisdom turned on its head...

At Work with the FT: Joanna Jensen, founder and CEO, Childs Farm

Joanna Jensen is having to sell her stables. The former horse breeder who left a career in investment banking says her children’s toiletries business “has just taken over my life — I don’t have time to ride”. Her two daughters Mimi, 10, and Bella, seven, are more into athletics than horses, she sighs. She does, however, have her daughters to thank for the new venture — Childs Farm — which began as a homemade recipe to soothe their sensitive skin in 2010. It is now a fully fledged business with a £2.1m turnover in 2015.

Wearables for babies: saving lives or instilling fear in parents?

Following the success of adult fitness wearables like Fitbit, new companies are connecting babies to smartphone apps and giving parents live information about their baby’s breathing, skin temperature, heart rate and sleeping patterns. The Owlet has adapted pulse oximetry technology (the clip they put on your finger in hospitals to monitor heart rate) to create a baby sock that monitors heart rate and oxygen levels. Sproutling has integrated the same technology into a strap that goes round th

Interview: Fiona Dawson, global president, Mars foods

At the Mars Foods testing centre in rural Leicestershire, Fiona Dawson greets the FT having just tasted new recipes. “We had salad with wholegrain, new dipping sauces, lasagne and stir-fry,” she says. Does she like the taste of Dolmio and Uncle Ben’s sauces? “Thankfully, I’m a big fan! I don’t think you could do a job like mine without loving your products.” As global president of Mars food, drinks, and multisales, one of about a dozen senior executives who report to Grant F Reid, the company president, Ms Dawson’s office is at headquarters in Brussels...

At Work with the FT: James Thornton, ClientEarth

At ClientEarth’s offices in east London, glass walls overlook leafy London Fields. James Thornton, 62, founder and chief executive, is an avid ornithologist, so bird feeders hang outside. The 60 or so lawyers occupied by fossil fuel, fisheries and air pollution law, enjoy fittingly green offices. Mr Thornton, who started the firm from a desk in a one-bedroom flat 10 years ago, greets the FT with warmth, before locking eyes in the manner of a Zen priest — which, incidentally, he also happens to be.

Swings, slides and iPads: the gaming companies targeting kids' outdoor play

Three-quarters of UK children now spend less time outside than prison inmates, according to a new survey, with the lure of digital technology partly to blame. But, in a world where gaming and screen time are an everyday reality, could the right technology actually get more kids to play outdoors? Hybrid Play is a Spanish start-up which uses augmented reality (AR) – patching computer imagery on to real life – to transform playgrounds into video games. A wireless sensor resembling an over-sized cl

Rosabeth Moss Kanter

AS ONE OF the world’s pre-eminent leadership experts, Harvard Business School professor Rosabeth Moss Kanter surprised many – herself included – when she tackled transport infrastructure in her latest book, Move: Putting America’s Infrastructure Back in the Lead. A constant business traveller, both nationally and internationally, she found herself delayed time after time by traffi c jams and airport hold-ups. “To move is to thrive,” she writes. “To be stuck is to lack opportunity.” Unsurprisingly, having written leadership books for some four decades, Kanter also has something to say on the subject in Move, notably what happens in the absence of leadership and a lack of coherent direction

Diversity at the top pays dividends

Does the gender of executives make a difference to business performance? The evidence is mounting that it does. McKinsey, the management consultancy, has published research showing that mixed-gender boards outperform all-male boards. Separate studies found a positive relationship between the diversity of executive boards and returns on assets and investments among Fortune-listed US companies. Sodexo, the outsourcing company, even has data that suggest global companies in which women make up at

Happy workplaces help companies perform better

Companies with a reputation for strong employee engagement and creating a happy workplace generate good publicity and cachet for their chief executives. But these companies are finding that what makes a great employer can also lead to business success. In fact, the link between employee attitudes and business performance has been known for decades. A series of influential experiments from the 1930s, known as the Hawthorne studies, showed the impact of improved workplace environments on overall factory outputs. One finding was that reducing the working day by half an hour saw productivity improve.
