Key takes
Participating in the Sustainers challenge, gives us the chance to learn about our own consumption behaviours to change habits to make a tangible difference today and into the future. The IPCC have published a new report that shows that Having the right policies, infrastructure and technology in place to enable changes to our lifestyles and behaviour can result in a 40-70% reduction in greenhouse gas emissions by 2050. This offers significant untapped potential. The evidence also shows that these lifestyle changes can improve our health and wellbeing. What’s good for the planet is good for us. Let’s be a part of the change we want to see.
Good intentions quickly disappear in the busyness of the day. This app keeps sustainability simple and visible. The game element makes it fun and ensures it truly becomes a team activity.
"Starting small and staying consistent — supported by the Sustainers app — helped us save 400,000 kg of CO₂, and genuinely changed my personal behavior for good."
“What an eye-opener—an app that gives you insight into the impact of your own daily actions. Simple, effective, and inspiring—it helps you make yourself, your team, and your company more sustainable within your own sphere of influence! No more excuses—just take action.”
“The sustainable transition is ultimately about people and their behavior. Making their own impact visible can be the difference between taking action and not taking action. Sustainers is fantastic at driving this behavioral change in a simple and engaging way.”
Through Sustainers' challenges, Klaverblad has measurably reduced CO₂ at both the organizational and individual level — a meaningful step toward net zero.
"Healthcare institutions are full of green ideas — Sustainers finally gave us the platform to bring those ideas together and turn them into real, rewarded action."
By deleting 60,000 emails alone, I saved an estimated 1,400 kg of CO₂ — Sustainers made our digital footprint visible and gave us concrete steps to reduce it.
Sustainers is one of the most effective tools I've seen for engaging employees in reducing a company's carbon footprint — impactful, practical, and genuinely motivating.
