Lessons in sustainability from the city that touches the clouds



The year is 2000 and Jan Levy is in Bolivia. A year into his MBA course, he had become disillusioned.

Fed up of the share price-obsessed budding bankers and consultants, he had made the trip to South America in his summer break to do some volunteering.

He is standing looking down on the capital La Paz, home to nearly 900,000 people. Some 3,650 metres above sea level, the city sits in what looks like a giant crater beneath the Altiplano, a vast plain 4,000 metres high.

Its central business district, with its skyscrapers and shiny buildings, stands out like a sore thumb. But what struck Levy as he surveyed the sprawling urbanisation were the bits outside of the thriving economic hub.

He saw the community, the poverty, the shacks. As the city had expanded, its modest new houses had been built on hillsides, packed in like sardines to make the most out of the usable land.

For Levy, La Paz served as a graphical representation of business and society – and the disconnection between the two.

He returned to Barcelona’s IESE Business School to complete the remaining year of his two-year MBA. His Bolivian experience had changed his outlook, and he set about putting together a business plan.

His idea – which would later in his career turn out to be very useful – was around a concept of employee volunteering. He wanted to make it strategically important, and to turn it into a leadership development experience.

This led him to Business in the Community (BITC), the membership organisation that specialises in social change. He then met Simon Hamilton, the founder of the consultancy Three Hands, which he soon joined.

Fast forward to the present day, Levy is still with Three Hands. It has grown from one man working in his attic, to two men working in their attics, to what it is now – a healthy small business.

The firm specialises in community engagement. It helps its clients – generally big corporates like British Gas, Sky, IBM and Lloyds Banking Group – revive their place in society. It’s about reminding them of their core purpose.

It’s not always obvious to the public what businesses are doing”, Levy says.

It’s not even obvious to many people inside corporate organisations what they’re doing, but more importantly, why they’re doing it. If people in the organisation don’t get it, why should the general public?

The benefits of being actively engaged with communities are huge – none more so than employee development. A successful business has a motivated, inspired workforce; and a workforce becomes motivated and gets inspired when they are given opportunities to do great things and feel they are part of something special.

Levy uses the example of a big insurance firm which he was working with to help it better understand its underserved markets. Three Hands set up a project for a group of people in the company’s communications department to spend two days with a charity that specialises in helping ethnic minorities on low incomes.

From that, they got a real feel about how they could possibly engage that kind of demographic in the future and what their needs are”, he says.

Some call it sustainability; others call it corporate social responsibility – or CSR. But Levy calls it helping companies serve a social purpose – and not just a financial one.

That said, there is evidence to suggest that those companies with well-formed approaches to CSR do perform better. One study, by academics in the US, said in January that investors who focused almost exclusively on a business’s financials estimated its fundamental value to be around 25% higher when a firm had a strong CSR record.

Meanwhile, 93% of CEOs surveyed by Accenture said they see sustainability as important to their company’s future success.

To those who say CSR – as a term or a concept – has passed its sell-by date, Levy says, “I don’t think it has. What’s confusing is this morphing from CSR to sustainability, but I don’t think we should get hung up on terminology.

With sustainability evolving almost as a new era of business, I think CSR and community is actually more relevant than ever.”

This belief is one he learned 14 years ago while standing overlooking La Paz, Bolivia’s city in a bowl, and one that could be vitally important in reconnecting business with its historical, socially-orientated roots.

Will Self-Driving Cars Be Better for the Environment?

Technologists, engineers, lawmakers, and the general public have been excitedly debating about the merits of self-driving cars for the past several years, as companies like Waymo and Uber race to get the first fully autonomous vehicles on the market. Largely, the concerns have been about safety and ethics; is a self-driving car really capable of eliminating the human errors responsible for the majority of vehicular accidents? And if so, who’s responsible for programming life-or-death decisions, and who’s held liable in the event of an accident?

But while these questions continue being debated, protecting people on an individual level, it’s worth posing a different question: how will self-driving cars impact the environment?

The Big Picture

The Department of Energy attempted to answer this question in clear terms, using scientific research and existing data sets to project the short-term and long-term environmental impact that self-driving vehicles could have. Its findings? The emergence of self-driving vehicles could essentially go either way; it could reduce energy consumption in transportation by as much as 90 percent, or increase it by more than 200 percent.

That’s a margin of error so wide it might as well be a total guess, but there are too many unknown variables to form a solid conclusion. There are many ways autonomous vehicles could influence our energy consumption and environmental impact, and they could go well or poorly, depending on how they’re adopted.

Driver Reduction?

One of the big selling points of autonomous vehicles is their capacity to reduce the total number of vehicles—and human drivers—on the road. If you’re able to carpool to work in a self-driving vehicle, or rely on autonomous public transportation, you’ll spend far less time, money, and energy on your own car. The convenience and efficiency of autonomous vehicles would therefore reduce the total miles driven, and significantly reduce carbon emissions.

There’s a flip side to this argument, however. If autonomous vehicles are far more convenient and less expensive than previous means of travel, it could be an incentive for people to travel more frequently, or drive to more destinations they’d otherwise avoid. In this case, the total miles driven could actually increase with the rise of self-driving cars.

As an added consideration, the increase or decrease in drivers on the road could result in more or fewer vehicle collisions, respectively—especially in the early days of autonomous vehicle adoption, when so many human drivers are still on the road. Car accident injury cases, therefore, would become far more complicated, and the roads could be temporarily less safe.


Deadheading is a term used in trucking and ridesharing to refer to miles driven with an empty load. Assume for a moment that there’s a fleet of self-driving vehicles available to pick people up and carry them to their destinations. It’s a convenient service, but by necessity, these vehicles will spend at least some of their time driving without passengers, whether it’s spent waiting to pick someone up or en route to their location. The increase in miles from deadheading could nullify the potential benefits of people driving fewer total miles, or add to the damage done by their increased mileage.

Make and Model of Car

Much will also depend on the types of cars equipped to be self-driving. For example, Waymo recently launched a wave of self-driving hybrid minivans, capable of getting far better mileage than a gas-only vehicle. If the majority of self-driving cars are electric or hybrids, the environmental impact will be much lower than if they’re converted from existing vehicles. Good emissions ratings are also important here.

On the other hand, the increased demand for autonomous vehicles could put more pressure on factory production, and make older cars obsolete. In that case, the gas mileage savings could be counteracted by the increased environmental impact of factory production.

The Bottom Line

Right now, there are too many unanswered questions to make a confident determination whether self-driving vehicles will help or harm the environment. Will we start driving more, or less? How will they handle dead time? What kind of models are going to be on the road?

Engineers and the general public are in complete control of how this develops in the near future. Hopefully, we’ll be able to see all the safety benefits of having autonomous vehicles on the road, but without any of the extra environmental impact to deal with.

New Zealand to Switch to Fully Renewable Energy by 2035

New Zealand’s prime minister-elect Jacinda Ardern is already taking steps towards reducing the country’s carbon footprint. She signed a coalition deal with NZ First in October, aiming to generate 100% of the country’s energy from renewable sources by 2035.

New Zealand is already one of the greenest countries in the world, sourcing over 80% of its energy for its 4.7 million people from renewable resources like hydroelectric, geothermal and wind. The majority of its electricity comes from hydro-power, which generated 60% of the country’s energy in 2016. Last winter, renewable generation peaked at 93%.

Now, Ardern is taking on the challenge of eliminating New Zealand’s remaining use of fossil fuels. One of the biggest obstacles will be filling in the gap left by hydropower sources during dry conditions. When lake levels drop, the country relies on gas and coal to provide energy. Eliminating fossil fuels will require finding an alternative source to avoid spikes in energy costs during droughts.

Business NZ’s executive director John Carnegie told Bloomberg he believes Ardern needs to balance her goals with affordability, stating, “It’s completely appropriate to have a focus on reducing carbon emissions, but there needs to be an open and transparent public conversation about the policies and how they are delivered.”

The coalition deal outlined a few steps towards achieving this, including investing more in solar, which currently only provides 0.1% of the country’s energy. Ardern’s plans also include switching the electricity grid to renewable energy, investing more funds into rail transport, and switching all government vehicles to green fuel within a decade.

Zero net emissions by 2050

Beyond powering the country’s electricity grid with 100% green energy, Ardern also wants to reach zero net emissions by 2050. This ambitious goal is very much in line with her focus on climate change throughout the course of her campaign. Environmental issues were one of her top priorities from the start, which increased her appeal with young voters and helped her become one of the youngest world leaders at only 37.

Reaching zero net emissions would require overcoming challenging issues like eliminating fossil fuels in vehicles. Ardern hasn’t outlined a plan for reaching this goal, but has suggested creating an independent commission to aid in the transition to a lower carbon economy.

She also set a goal of doubling the number of trees the country plants per year to 100 million, a goal she says is “absolutely achievable” using land that is marginal for farming animals.

Greenpeace New Zealand climate and energy campaigner Amanda Larsson believes that phasing out fossil fuels should be a priority for the new prime minister. She says that in order to reach zero net emissions, Ardern “must prioritize closing down coal, putting a moratorium on new fossil fuel plants, building more wind infrastructure, and opening the playing field for household and community solar.”

A worldwide shift to renewable energy

Addressing climate change is becoming more of a priority around the world and many governments are assessing how they can reduce their reliance on fossil fuels and switch to environmentally-friendly energy sources. Sustainable energy is becoming an increasingly profitable industry, giving companies more of an incentive to invest.

Ardern isn’t alone in her climate concerns, as other prominent world leaders like Justin Trudeau and Emmanuel Macron have made renewable energy a focus of their campaigns. She isn’t the first to set ambitious goals, either. Sweden and Norway share New Zealand’s goal of net zero emissions by 2045 and 2030, respectively.

Scotland already sources more than half of its electricity from renewable sources and aims to fully transition by 2020, while France announced plans in September to stop fossil fuel production by 2040. This would make it the first country to do so, and the first to end the sale of gasoline and diesel vehicles.

Many parts of the world still rely heavily on coal, but if these countries are successful in phasing out fossil fuels and transitioning to renewable resources, it could serve as a turning point. As other world leaders see that switching to sustainable energy is possible – and profitable – it could be the start of a worldwide shift towards environmentally-friendly energy.
