Has 2021 been a great year for the planet? Well, almost certainly not – and that’s putting it lightly. The climate crisis is worsening and governments around the world are continuing to dither and delay. Despite another year of stern warnings and worrying predictions, we’re all severely and irreversibly damaging the planet.

But things aren’t all bad. There are still plenty of reasons to be cheerful – or if not exactly cheerful, to be not that miserable. Cities are still innovating and doing their best to embark on green initiatives. And all around the world, people, businesses and local governments have found ways to do their bit to be more sustainable.

From mass reforestation projects and sustainable department stores to cooperative housing and revolutionary urban planning, cities are transforming their citizens’ way of life. Indeed, the bright side of the current crisis isn’t just bright: it’s blindingly promising. There are obviously plenty of people around the world who want to create real change, and they definitely deserve a bit of recognition.

As part of this year’s Time Out Love Local Awards, we asked you to name the best green city projects that you heard about in 2021. Here are all the award winners, along with a handful of other standout works that cropped up across the globe this year.

Amazing projects that made cities around the world greener in 2021

1. London’s Restart Project teaches us how to reduce waste

Reducing waste from electronic devices requires a pretty niche skillset, but the Restart Project is trying to rectify that – one community event at a time. It is helping Londoners learn more about sustainable electronics and how to reduce consumption of everything from smartphones and tablets to toasters and vacuum cleaners. This year, the Project went further and launched Materials Matter, an educational site that aims to help children across the UK understand the environmental impact of a smartphone.

2. Making NYC’s gardens greener with the Restoration Project

The New York Restoration Project, founded founded by actress/singer/icon Bette Midler, has been working on regreening NYC for almost a quarter of a century, but in 2021 the team’s programmes really caught our eye. The Jefferson Houses in East Harlem, Cauldwell Youth Garden in the South Bronx and Hill Street Community Garden in Staten Island were just a few of the places spruced up by the NYRP’s trellises, terraces, shrubs, raised beds, composts and rainwater harvesting systems.

3. Superblocks are transforming the city streets in Barcelona

Barcelona’s glorious superilles continue to swallow up greater areas of the city, greenifying and pedestrianising as they go. In 2021, the Catalan capital completed the transformation of streets in Sant Martí, extending the overall superblock area by more than 14,000 square kilometres, and started work on the streets of Rector Triadó and Torre d’en Damians. One of the twenty-first century’s most ambitious urban-planning projects grows more impressive by the year.

4. The pioneering cooling measures in Tokyo

Keeping cities naturally cool reduces the need for air conditioning and so lowers energy consumption. In the lead-up to the 2021 Olympics, Tokyo needed to find ways to make its sweltering, 40C summer more bearable. The result was an ingenious array of cooling tech, from wooden architecture (like the cedar National Stadium) to solar paint (on running surfaces and roads) and water spray systems.
