Hot or Cool Institute and partner organisations – the Club of Rome, Sitra, Medwaves, and PS Lifestyles project – are launching their new report “A Climate for Sufficiency: 1.5-Degree Lifestyles” on October 7 2025, at 11.00 CET/10:00 GMT.

The remaining carbon budget is now so limited that, at current burn rates, the planet will cross the critical 1.5°C warming limit within the next five years. But what does approaching or crossing the 1.5°C threshold mean for our consumption and ways of living?
1.5°C is not a random number arbitrarily pulled out of thin air. The 1.5-Degrees Lifestyles report series grounds climate change and its impacts on people’s lifestyles and consumption, and helps governments, civil society and businesses understand what decisions would shape future ways of living in a prosperous direction.
As climate change has progressed so has growing inequality in society, youth anxiety about future prospects, and general decline in wellbeing. Whereas dominant “solutions” towards climate change have focused on technology and economic interventions, climate change is both driven and impacted by consumption and lifestyles. Through consumption and lifestyles, climate solutions can ensure legitimacy, buy-in and contribution from citizens towards radical changes needed as we cross ecological thresholds.
At this threshold, how much can we afford to use the remaining carbon budget in a manner that is fair, to support human flourishing while achieving climate stability? This new report “A Climate for Sufficiency: 1.5-Degree Lifestyles” demonstrates that a sufficiency approach is essential, especially as we appear on course to transgress the 1.5°C environmental ceiling while a large share of humanity remains below the floor of essential consumption.
New and bold recommendations in this report show that there is yet room to avert worse outcomes, granted we make some transformational, and yet possible, shifts today.
