Efficient but Overhyped: A Local's Disappointment

I've lived in Flachau all my life, and while I applaud Holzwärme Flachau GmbH's efforts to reduce their carbon footprint, my personal experience with them has been underwhelming. As someone who's passionate about environmental causes, I was excited to learn more about their operations and potentially switch to their services. However, after visiting their facilities, I was struck by the lack of transparency regarding their actual wood sourcing practices. The tour guide seemed evasive when I asked about the sustainability of their wood chip suppliers, which raised some red flags for me. Moreover, despite their claims of being CO²-neutral, I've noticed an increase in local air pollution during peak production times, which contradicts their eco-friendly image. Perhaps it's just a matter of growing pains, but as a customer, I expect more than just a sleek marketing campaign. Until they address these concerns and provide clearer information about their practices, I'll remain skeptical about their commitment to true sustainability. For now, I'll have to look elsewhere for my energy needs.
