100% Renewable: TÜV Rheinland recertifies First Climate Eco Electricity Products

2025 audit successfully concluded / “Green by Choice” energy products verified as sustainably sourced

All of First Climate’s Green by Choice products are annually reviewed by TÜV Rheinland Energy & Environment GmbH. First Climate recently successfully concluded this year's TÜV Rheinland audit. The independent audit’s certification confirms that the energy used for First Climate’s electricity products comes from 100% renewable sources.

Over the past few years, both demand for renewable energy and consumer expectations around quality have grown significantly. An increasing number of companies and energy providers are making a deliberate choice to include green electricity products in their renewable energy procurement strategies. Independent certifications play a key role in ensuring the credibility and transparency of these high-quality energy products.

TÜV Certified Green Electricity Quality

All First Climate "Green by Choice" products have been reviewed and certified annually by TÜV Rheinland since 2019. First Climate has now once again successfully completed the audit for its unique “Green by Choice” modular system. The “Green by Choice” system is distinct due to its modular design, allowing customers to tailor their green electricity package to their individual needs. They can choose from four product variants and add a range of optional features: from the country of origin or generation site, to the technology used for production, and even the age of the installation.

The TÜV certification process includes a comprehensive review of origin certificates such as Guarantees of Origin (GoOs), I-RECs, RECs, and others in accordance with the applicable regulations of the respective national certification system or energy market.

As part of the audit process, the “Green by Choice” products “Naturstrom BASIS,” “Naturstrom Wasser und Wald,” “Naturstrom ReInvest lokal,” and “Naturstrom Kind und Zukunft” underwent rigorous quality control. The quality labels are awarded based on specific criteria and minimum requirements that must be met to ensure transparency, credibility, regional relevance, and environmental responsibility which are all key expectations from today’s consumers. A central element of this is the use of 100% renewable sources for clean energy generation. The recent re-certification by TÜV and the awarding of its quality seal confirm the high standards of First Climate’s green electricity solutions.
