Five cities proving that we can quit fossil fuels

Powering a city is a major undertaking: all that economic activity, culture and innovation requires a lot of fuel. As a result, while cities house just over half the world’s population, but are responsible for nearly 80 per cent of the world’s energy consumption.

The result of all this is rising greenhouse gas emissions.  This year looks set to smash all previous temperature records, and cities are no strangers to the consequences of a hotter planet. From rising sea levels, encroaching on coastline properties, to droughts and heatwaves that threaten citizens and businesses, the likes of Bangkok, Paris, New York and countless others know what climate change looks like first hand.

So what can be done about it? Weaning our cities off fossil fuels, the most polluting sources of energy, is key – but this is much more easily said than done. Many city governments lack the ability to directly control the energy mix of their electricity as policies are often set at state or national levels. With few national governments setting ambitious goals to be fossil fuel-free, the odds appear stacked against cities.

Despite these challenges, some major cities are showing that it is possible to reduce fossil fuel usage. This year over 300 cities joined in CDP’s cities programme, sharing information on how they are taking actions to reduce carbon emissions and managing climate risks. Over a third of these cities told us they have some kind of renewable energy goal in place. More promisingly still, some, including the city of Aspen in the US, have in fact already declared themselves fossil fuel-free.

Here are five cities already making the shift to a low-carbon future.

Cape Town, South Africa

Locals in Cape Town, who affectionately refer to it as the Mother City, are familiar with the country’s ongoing issues with energy supply and demand. Over the past six years the price of electricity has jumped by 340 per cent, putting a strain on local businesses and households. The city’s current energy mix is heavily reliant on coal, which supplies up to 72 per cent of its electricity.

However with growing concern over energy security and the city’s high carbon footprint, officials are catalysing a transition to renewables. Cape Town aims to source 10 per cent of the city’s electricity from renewable energy by 2020 – a change that will save greenhouse gas emissions by 1m metric tons. 


Houston, Texas

Texas may be known as an oil-rich state, but its most populous city, Houston, happens to be the largest municipal purchaser of green power in the US. The city estimates it is using almost 623,000 mWh of green power per year, which is equivalent to the amount of energy needed to power over 55,000 homes annually.  

This power plan benefits locals too – Houston reports being able to maintain a relatively flat power price while increasing the amount of renewable energy in its mix, proving that going green doesn’t have to be costly.

Stockholm, Sweden

Sweden’s capital had already set an ambitious goal to be 100 per cent fossil fuel-free by 2050, but decided it should aim to achieve that target ten years sooner. Stockholm is making this task easier by first reducing the amount of overall energy it uses, then replacing fossil fuels with alternative sources such as biogas, biodiesel and solar. It doesn’t have far to go: fossil fuels currently make up just 9 per cent of its energy mix for power.

Sydney, Australia

Sydney proudly boasts one of the most ambitious emissions reduction targets in the country, and is hoping to achieve that in part through obtaining 30 per cent of its electricity from renewable sources by 2030.  It also has the farthest to go compared to other cities on this list in this regard – its current energy mix is dominated entirely by coal.

The city’s renewable energy master plan draws on solar PV, solar thermal hot water, wind energy and geothermal from within the city’s boundary and other technologies (such as onshore wind turbines) to meet its goal. 

Tokyo, Japan

One of the world’s largest mega-cities and among the first to earn that title, Tokyo has a big task in powering its 62 sprawling municipalities. The city is currently heavily reliant on fossil fuels, but officials are aiming to get a fifth of its total energy from renewable sources by 2024.

Part of its plan to achieve this is to establish a system in which consumers can chose clean energy – giving power, literally, to the people.

CityMetric is now City Monitor! Come see us at our new home

City Monitor is now live in beta at citymonitor.ai.

CityMetric is now City Monitor, a name that reflects both a ramping up of our ambitions as well as our membership in a network of like-minded publications from New Statesman Media Group. Our new site is now live in beta, so please visit us there going forward. Here’s what CityMetric readers should know about this exciting transition.  

Regular CityMetric readers may have already noticed a few changes around here since the spring. CityMetric’s beloved founding editor, Jonn Elledge, has moved on to some new adventures, and a new team has formed to take the site into the future. It’s led by yours truly – I’m Sommer Mathis, the editor-in-chief of City Monitor. Hello!

My background includes having served as the founding editor of CityLab, editor-in-chief of Atlas Obscura, and editor-in-chief of DCist, a local news publication in the District of Columbia. I’ve been reporting on and writing about cities in one way or another for the past 15 years. To me, there is no more important story in the world right now than how cities are changing and adapting to an increasingly challenging global landscape. The majority of the world’s population lives in cities, and if we’re ever going to be able to tackle the most pressing issues currently facing our planet – the climate emergency, rising inequality, the Covid-19 pandemic ­­­– cities are going to have to lead the way.

That’s why City Monitor is now a global publication dedicated to the future of cities everywhere – not just in the UK (nor for that matter just in the US, where I live). Our mission is to help our readers, many of whom are in leadership positions around the globe, navigate how cities are changing and discover what’s next in the world of urban policy. We’ll do that through original reporting, expert opinion and most crucially, a data-driven approach that emphasises evidence and rigorous analysis. We want to arm local decision-makers and those they work in concert with – whether that’s elected officials, bureaucratic leaders, policy advocates, neighbourhood activists, academics and researchers, entrepreneurs, or plain-old engaged citizens – with real insights and potential answers to tough problems. Subjects we cover include transportation, infrastructure, housing, urban design, public safety, the environment, the economy, and much more.

The City Monitor team is made up of some of the most experienced urban policy journalists in the world. Our managing editor is Adam Sneed, also a CityLab alum where he served as a senior associate editor. Before that he was a technology reporter at Politico. Allison Arieff is City Monitor’s senior editor. She was previously editorial director of the urban planning and policy think tank SPUR, as well as a contributing columnist for The New York Times. Staff writer Jake Blumgart most recently covered development, housing and politics for WHYY, the local public radio station in Philadelphia. And our data reporter is Alexandra Kanik, whose previous roles include data reporting for Louisville Public Media in Kentucky and PublicSource in Pittsburgh, Pennsylvania.

Our team will continue to grow in the coming weeks, and we’ll also be collaborating closely with our editorial colleagues across New Statesman Media Group. In fact, we’re launching a whole network of new publications, covering topics such as the clean energy transition, foreign direct investment, technology, banks and more. Many of these sectors will frequently overlap with our cities coverage, and a key part of our plan is make the most of the expertise that all of these newsrooms combined will bring to bear on our journalism.

Please visit citymonitor.ai going forward, where you can also sign up for our free email newsletter.


As for CityMetric, some of its archives have already been moved over to the new website, and the rest will follow not long after. If you’re looking for a favourite piece from CityMetric’s past, for a time you’ll still be able to find it here, but before long the whole archive will move over to City Monitor.

On behalf of the City Monitor team, I’m thrilled to invite you to come along for the ride at our new digs. You can follow City Monitor on LinkedIn and on Twitter. If you’re interested in learning more about the potential for a commercial partnership with City Monitor, please get in touch with our director of partnerships, Joe Maughan.

I want to thank and congratulate Jonn Elledge on a brilliant run. Everything we do from here on out will be building on the legacy of his work, and the community that he built here at CityMetric. Cheers, Jonn!

To our readers, on behalf of the City Monitor team, thank you from all of us for being such loyal CityMetric fans. We couldn’t have done any of this without you.

Sommer Mathis is editor-in-chief of City Monitor.
