How Bratislava Is Turning Business into a Partner for Change

2025-12-09T12:08:36+01:00December 8th, 2025|

Author: Barabara Jarkiewicz Bratislava is redefining how cities and businesses can work together to tackle climate change. Through the Bratislava Mayor’s Climate Challenge, the Slovak capital is showing that real progress on emissions requires shared responsibility, trust and transparency.  “The city has a direct influence on only about 11% of emissions in Bratislava,” says Marián Zachar, project manager of the Bratislava Mayor’s Climate Challenge. “Companies, residents and private transport are responsible for about a third of the rest. The city wants to lead by example through its own investments and policies, but at the same [...]

‘We were lucky’: Twin City interview with Lund

2025-12-04T08:35:06+01:00December 4th, 2025|

The Swedish city of Lund has a unique perspective in the EU Cities Mission – how has it shaped its climate activities and learning? In a recent interview, Tommy Bengtsson and Juliet Leonette from the city’s climate team explain.  Of the many valuable opportunities available through the EU Cities Mission Cities, the chance to learn from peers in other cities is unique. Over 180 cities have already participated in peer-learning programmes through the Mission, collaborating not only with near neighbours but across more distant European borders too.   Lund, a mid-sized city on the southern tip of [...]

GUEST BLOG: Pedal Power: the COP Bike Ride crossed 19 Mission Cities and delivered a strong message on cycling at COP30 in Belém

2025-12-03T10:26:04+01:00November 27th, 2025|

When cities embrace bike-friendly design, they not only reduce emissions but encourage healthier communities, calmer streets and a culture of sustainability. Acting EU Cities Mission Board Chair Paulo Ferrão and board member Françoise Guaspare reflect on the significance of a citizen-driven initiative to promote the European Declaration on Cycling at COP30. Not all roads to COP30 in Belém, Brazil were created equal. This was especially true for hundreds of riders in the COP Bike Ride, a citizen initiative that carried ten proposals to leverage cycling for climate protection to November’s  UN Climate Conference in Belém. The [...]

Climate-Neutral Cities in Albania: Cross-country collaboration via a national platform?

2025-11-21T08:29:59+01:00November 21st, 2025|

What happens when you bring together Albanian municipalities, a Mission City, national institutions, academia, and NetZeroCities representatives? A great co-creation process begins! Natalia Lewandowska from ICLEI Europe writes that the stage is now set for establishing an Albanian national platform to accelerate climate neutrality.  Albania’s path toward EU accession has placed sustainability, climate action, and urban development high on the national agenda. As the country aligns its policies with the European Green Deal and the EU’s climate objectives, cities have a central role to play in driving this transformation – but mobility remains one of Albania’s [...]

Preparation vs prevention? How cities can find a balance as they face challenges of climate change

2025-11-10T12:06:21+01:00November 10th, 2025|

Will we run out of the materials we need for clean energy generation? How do we balance adapting to a changing climate with mitigating and preventing its worst effects?  And what role could AI play in achieving climate neutrality? These are some of the key questions facing cities and, in three upcoming papers introduced in this post, NetZeroCities  partners Dark Matter Labs, Demos Helsinki and Polimi take a deeper look. Anticipating future problems and opportunities should be a priority for organisation’s risk management and to inform their decision making – and cities are no exception.  Yet [...]

Molecular Milan: Tapping the power of super-local climate action

2025-10-07T14:02:50+02:00October 7th, 2025|

Can a single neighbourhood become a testing ground for a city’s net-zero future? Milan’s Climate City Contract team is putting the theory into practice in the northeastern district of Adriano-Crescenzago-Lambro and report here on how urban experimentation, social equity, and ecological regeneration can work hand in hand to accelerate the climate transition.  Molecules of change  When facing a huge challenge, ‘start small’ can be helpful advice: breaking the problem down into manageable chunks can help to avoid becoming overwhelmed, while the mini successes of each completed task can build momentum and make progress more noticeable.  But [...]

Everybody needs good neighbours: How four nearby European cities are taking on big climate challenges together

2025-09-23T14:59:57+02:00September 23rd, 2025|

One began their Mission City journey from ‘less than zero,’ while another is a former European Green Capital – but all share a similar need to meet their climate ambitions. They told a meeting of experts from across Europe how they’re changing their cities.  What does it take to become a European Green Capital? Measured on seven indicators, including air quality, biodiversity, and climate change mitigation, any winning city will be pursuing high environmental and sustainability standards.   Yet, even with the knowledge acquired through this work, the challenge of climate neutrality requires another level of ambition [...]

Building for the Future: How Warsaw’s Green Building Standard is Changing the City

2025-09-25T12:33:43+02:00September 16th, 2025|

Author: Ayden Maher A library that set the tone  Before it even opened its doors, the new public library in Warsaw’s Białołęka district was winning awards. Designed with solar panels, natural lighting, and spaces shaped by greenery, it became the first municipal building to be certified under the Warsaw Green Building Standard (WGBS). For the city, the library was more than just a local success; it was proof that climate ambition could be translated into tangible, physical spaces.  “We cannot have a strategy that says we will protect biodiversity and then build as business-as-usual,” says Jacek [...]
