Research cutting-edge technologies, enact policies, protect ecosystems, and modernize industry to cut down carbon emissions. Manage your resources well and you might survive. ACCESSIBLE, BUT COMPLEX SIMULATION Will you favor industrial reforms, nature conservation or people initiatives? There are many ways to solve climate change and reduce pollution. But saving the planet is not an easy task. The more carbon emissions you produce the more extreme events you will have to deal with. STEER SOCIETY & INDUSTRY You have to balance the power-generating industry, social reforms, ecological policies and scientific endeavors. Will you transition from fossil fuels as fast as possible? Or will you focus on carbon capture technologies first? Experiment with new strategies and don’t be afraid to start again. 235 UNIQUE CARDS Game cards represent inventions, laws, social advancements, or industries - each designed on the basis of real-world climate science. In addition, partially randomized world events occur, forcing you to adapt your strategy. Gradually unlock new cards in the game encyclopedia and chart your path towards a new future. IMPACTFUL EVENTS, HIGH REPLAYABILITY The world of Beecarbonize reacts to your actions. More emissions mean more floods or heatwaves, investing in nuclear power raises the risk of a nuclear incident, and so on. Learn more with each run and you might overcome environmental catastrophes, social unrest, and even avert the end of life on earth. Beecarbonize is a strategic challenge that lets you experience phenomena shaping our everyday lives hands-on. Just how many seasons can you last? NEW HARDCORE MODE We are introducing Hardcore mode, the ultimate challenge in Beecarbonize for experienced players. In Hardcore mode you will face the harsh reality of climate change.
