About us

Klima-Kollekte serves as a CO2 offset initiative of Christian churches, enabling each individual to actively offset their carbon footprint. These offset payments are strategically directed towards projects in Global South countries, where they not only alleviate local poverty by empowering women, safeguarding health, and fostering opportunities but also contribute to a reduction in CO2 emissions, thereby protecting the climate. These climate protection initiatives are affiliated with church organizations or their partners, ensuring that your contribution to climate protection is utilized with transparency and trust, aligning with the values upheld by the partner houses of Klima-Kollekte.

Established in 2011, Klima-Kollekte is a nonprofit entity committed to this cause. Oversight and decision-making lie with the management and shareholders' meeting of Klima-Kollekte gGmbH, who, after consulting the expert committee, determine the selection of projects.

The dedicated team at Klima-Kollekte is here to support you in adopting environmentally friendly practices, aiding in the preservation of our planet. We offer comprehensive emission calculations and guidance on climate protection management. Any remaining emissions can be effectively offset through projects in the realm of renewable energies and energy efficiency facilitated by Klima-Kollekte.

We eagerly anticipate the opportunity to collaborate with you.

"What are the differences between Klima-Kollekte and other providers?"

The Klima-Kollekte supports climate-friendly action and thus preserves creation. In doing so, it works with the particularly demanding Gold Standard for the Global Goals. Its partner organizations are based in the church context and most of them have many years of experience in development cooperation. The climate protection contributions are used in a transparent and trustworthy manner - this is what the Klima-Kollekte and its partner organizations stand for.
