‘If it’s not economically competitive, we have lost the game’

2026-07-30T16:36:13+02:00July 27th, 2026|

Kozani is part of “a region in transition,” says the Greek city’s climate lead, as it plans for a future without the mining industry that until recently sustained it. Showing citizens the value of clean energy to their finances, as well as to the climate, is crucial – and finance experts from NetZeroCities’ Capital Hub are working closely with the city on the numbers. Michail Kastanaras is “quite new to the struggle” that Kozani began a few years ago, he says, but he and his colleagues are now playing a special role within the local climate [...]

Strategies to make innovation stick in cities

2026-07-03T10:15:11+02:00July 3rd, 2026|

In this second blog on city innovation, NetZeroCities partners TNO show how cities – after identifying their challenges, outlined in part one – can follow five strategies to make innovation not a ‘nice to have’ but an inevitable part of their results. In our first blog, we described 15 recurring challenges that quietly stall innovation in cities, showing up as slow progress, unfinished pilots, fragile initiatives, and innovation that depends on personal energy rather than organisational support. But naming challenges is only half the battle. In our work on addressing complex societal challenges with public organisations [...]

What are ‘negative emissions’ and what do they mean for cities?

2026-07-13T14:45:51+02:00June 18th, 2026|

Cities are trying to rapidly reduce their greenhouse gas emissions and reach net zero, but why ‘net’ zero? This is where negative emissions come in. Paul Barton from NetZeroCities’ partner ICLEI Europe explains how critical these are for cities’ climate neutrality goals. A less considered part of the terms “net zero” and “climate neutral” is that they imply that some carbon emissions can’t be mitigated by 2030. These leftover or “residual” emissions therefore need to be cancelled out through actions that remove carbon from the atmosphere. Why do cities need negative emissions? The removal and storage [...]
