Browser games have always offered accessibility and speed. Today, they bring something even more powerful to the table: sustainability. This summer, GameDistribution by Azerion, Playgama.com, and the Playing for the Planet Alliance, facilitated by the United Nations Environment Programme (UNEP), are launching the Green Web Game Jam 2025, the first browser-based spin on the Green Game Jam.
From July 4 to 15, developers worldwide are invited to create impactful HTML5 games with one mission: to raise environmental awareness and drive real-world change through gameplay. GameDistribution proudly supports and amplifies this movement.
A Game Jam With a Global Goal
Since 2020, the Green Game Jam has challenged leading game studios, from Supercell to Microsoft, to embed eco-conscious content into their live games. As a result, the jam has driven impressive impact. In 2024 alone:
- 108M+ daily active users engaged with sustainable gaming content
- 610K trees were planted
- 1.5K ft² of land was protected
- 30K real-world actions were taken by players
- 45 game teams participated across platforms and genres
Now, the Green Web Game Jam reaches an even broader audience: web gamers. As Yuliya Nabieva, VP of Gaming at Azerion, notes, this is a rare opportunity to engage the growing ecosystem of web developers in meaningful, playable experiences that drive both innovation and positive change, a vision that GameDistribution deeply shares.
Moreover, with over 500 million users playing HTML5 games globally, the jam taps into a high-volume, low-barrier format that’s both scalable and sustainable.
“Browser games consume minimal energy and extend device lifespans, making them one of the most sustainable ways to play,” says Dmitry Kachmar, founder of Playgama.
The Structure of the Green Web Game Jam
From July 4–15, developers can join the jam on itch.io. Thanks to its fast-paced format and open access, the jam welcomes everyone, from indie creators to major studios.
Louisa Keight, Project Lead at Playing for the Planet, is greatly looking forward to seeing the range of approaches and innovative ideas the diverse and creative Playgama community will bring to this first web-based edition.
The challenge is to create short-form browser games that raise awareness of pressing environmental issues, including pollution, overconsumption, deforestation, and climate change. The twist? This isn’t just about creating compelling stories. The objective is also to devise gameplay mechanics that encourage responsible behaviors and actions.
✨ The three winners will:
- Be published across GameDistribution’s global network (2,000+ platforms)
- Be featured on the Playgama homepage
- Appear in a global showcase on September 1, 2025
And, best of all, GameDistribution and Playgama will donate 100% of their 2025 revenue share from the winners to On the Edge, a conservation nonprofit focused on biodiversity.
From Gameplay to Global Impact
The theme of the Green Game Jam 2025, “Nurture Yourself With Nature,” invites developers to craft experiences that spark empathy and inspire real-world environmental action. Over the years, the jam has shown how powerful storytelling and smart mechanics can turn gameplay into a measurable impact.
