In cities, the ‘Road to Paris’ began more than a decade ago. In 2015, as we come together as a global community around the COP21 negotiating table, cities are factoring into the climate equation in a big way. This past year has seen the global significance of cities brought to the fore, with much applause for the decisive work of mayors, and the crucial impact the world’s megacities have on our global future.

Cities are – without hyperbole – where the future happens first. This is true on many levels: today, cities command vast resources, consuming more than two-thirds of the world’s energy and accounting for 70 per cent of global greenhouse gas emissions with their booming economies and broad-scale systems. Because they need to deliver services and function on a daily basis, cities are natural breeding grounds for innovation, lending themselves to reinvention and even renaissance.

And this will only continue: by 2050, 70 per cent of the world’s population will live in cities, meaning that the majority of the globe’s human capital will be driving city dynamics in some way.

This concentration of resources may look to some like a concentration of responsibility in cities, because that is where the future will be decided. And, to a large extent, that is true. But I see it not as a daunting challenge, but as a thrilling opportunity – and one that mayors are already stepping up to capitalise upon. As Chair of C40 Cities Climate Leadership Group, I would like to emphasise the power that cities have to implement changes that will impact people’s daily lives.

 

Opportunities to create a low carbon future

Recent research from the Global Commission on the Economy and Climate shows that a group of less than 500 cities – including nearly all of the C40’s member cities – will be responsible for 60 per cent of global economic growth and 50 per cent of greenhouse gas emission increases between now and 2030 (www.c40.org/research).

Additionally, new C40 research indicates that urban policy decisions made before 2020 could determine up to one-third of the remaining safe global carbon budget that is not already locked in by past decisions. These findings are significant in the context of COP21: negotiations for a critical new climate treaty concern action that will be taken after 2020, but we now know that mayors in

office today have the opportunity to ensure a low carbon future for our planet (www.c40.org).The report calculates that moving from a business as usual scenario to low carbon urban development across all the world’s cities would save 45 gigatonnes CO2 by 2030 – equivalent to eight times the current emissions of the United States. And this kind of investment – which cities are already pursuing – also makes strong economic sense: investing in low carbon infrastructure before 2020 will be four times less expensive than having to replace high carbon infrastructure in the future. The even better news is that building our cities smarter – by investing in low emission transport, more efficient buildings and waste management – represents a US$17 trillion opportunity worldwide by 2050 (http://newclimateeconomy.net/news).

 

Support from national governments

Cities hold the key to our future. But that does not mean that national governments have no role to play. Like much of the rest of the world, mayors hope to see heads of state sign an international treaty at the COP21 climate negotiations to cut emissions at the national level. We just want to gently remind them that when they return home – high on the success of international collaboration – that is when the real collaboration begins.

"Since COP15 in Copenhagen, mayors have undertaken more than 10,000 climate actions"

Cities have been committing to reducing carbon emissions through various pathways for well beyond the 10 years C40 has existed. Since the much-cited COP15 in Copenhagen, which the world largely deemed a catastrophe, mayors have undertaken more than 10,000 climate actions.

Research C40 completed in partnership with Arup indicated that – as of September 2014 – 228 cities had committed to reducing their greenhouse gas emissions. Taken together, these commitments alone represent an opportunity to save 13.0 gigatonnes CO2 equivalent by 2050. (Working Together: Global Aggregation of City Climate Commitments, www.c40.org/research).

With support from their national governments, cities can do even more. Separate research with Stockholm Environment Institute demonstrates that cities can make meaningful contributions towards more aggressive national emissions targets, helping bridge the global emissions gap. (Advancing climate ambition: cities as partners in global climate action, www.c40.org, 2014).

 

Mayors are already taking action

Fortunately, from a city perspective, COP21 is not the beginning of the road – nor is it the end. For 10 years, the global network of C40 – representing more than 640 million people and a quarter of global GDP – has been facilitating collaboration and solutions for its members, which now number at 80+.

C40 is an engine for progress on climate change, deploying critical research and facilitating sharing of knowledge and ideas between cities that not only helps reduce carbon emissions, but also makes cities cleaner, safer and more economically prosperous places to live and work.

Increasingly, this means fostering knowledge transfer between cities not just in the developed world, but also in the global South. In fact, in 2015, for the first time, half of C40’s member cities are from the South, an area that is rapidly urbanising and is critical in shaping the future of urban spaces.

And the flow of information is not unbalanced: Latin America is leading globally when it comes to sustainable public transit systems, for example. Earlier this year, C40 held a Latin American Mayors Forum – the first-ever regional forum of its kind – where cities announced the international Declaration on Clean Buses, demonstrating a commitment to reducing emissions and improving air quality by incorporating low- and zero-emission buses in city fleets.

In August, my city – Rio de Janeiro – became the world’s first city to be fully compliant with the Compact of Mayors, the world’s largest common platform for cities to report their emissions, set targets and develop plans to cut emissions and prepare for the effects of climate change (www.compactofmayors.org).

Coupled with the last new membership of Chinese cities in the C40 network – including the addition of Guangzhou and Nanjing in just the last few months – these developments further demonstrate the power of the often-overlooked cities of the global South. With the right support from national governments – including assistance with financing and creditworthiness – and recognition by the global community, cities of this kind can become models of sustainable urban development.

For the past year, governments, businesses and citizens around the world have anticipated COP21 as some kind of last chance to turn the tide of global climate change. And yes, a strong international agreement is an important step towards ensuring a climate-safe future. But no matter what happens, cities and their leaders will continue to move steadily forward on their mandate of making their cities better places to live and work. The decisions mayors make every day to serve their citizens are the same actions driving us toward a brighter future.

Eduardo Paes

Eduardo Paes has dedicated his entire career to public service in Rio de Janeiro. Fresh from law school, he became Deputy Mayor of the Jacarépaguá and Barra districts at age 23. Since then he has been Alderman, Federal Chamber Deputy, the city’s Environment Secretary and State Secretary for Tourism, Sport and Leisure. In 2008, he was elected Mayor of Rio and led the successful campaign to host the Olympics in 2016. Four years later, he was re-elected for a second term and became Chair of the C40 Cities Climate Leadership Group (C40) at the end of 2013

C40 Cities Climate Leadership Group

The C40 Cities Climate Leadership Group, now in its 10th year, connects more than 80 of the world’s greatest cities, representing 600+ million people and one quarter of the global economy. Created and led by cities, C40 is focused on tackling climate change and driving urban action that reduces greenhouse gas emissions and climate risks, while increasing the health, wellbeing and economic opportunities of urban citizens. The current chair of the C40 is Rio de Janeiro Mayor Eduardo Paes; three-term Mayor of New York City Michael R. Bloomberg serves as President of the Board. C40’s work is made possible by our three strategic funders: Bloomberg Philanthropies, Children’s Investment Fund Foundation (CIFF), and Realdania
