In the energy domain, we provide municipalities and citizens' associations with expertise in order to promote a sustainable and safe energy system with minimal greenhouse gas emissions. We provide consultations, publish awareness-raising materials, organise thematic workshops, conferences and excursions. We have established an online database on renewable sources of energy www.zdrojeenergie.cz, a website dealing with climate change www.zmenaklimatu.cz and a webpage with information on nuclear energy www.temelin.cz.

Calla focuses on nature protection, particularly in South Bohemia. We actively oppose projects that might damage valuable natural sites, and help people who want to defend nature around them. We promote near-natural restoration of mining sites, especially sand pits, and we take care of some sites ourselves (www.calla.cz/piskovny). We protect old trees and animal species that live attached to each other (www.calla.cz/stromyahmyz). In addition, you can adopt the Sand Martin through us (www.calla.cz/brehule).

Besides ordinary environmental consultancy issues, we offer help in the following areas: sustainable energy, nature and landscape protection and environmentally friendly reclamation of mining sites, in which we specialise.

Eco-consulting

An electronic monthly magazine provides information on Calla's activities and projects. It contains opinions, thematic essays, invitations, notices and other important information. In cooperation with Hnutí DUHA, Calla organises regular discussion evenings known as "Green Thursdays" on various topics related to environmental issues. For several years now, we have been organising a series of guided natural scientific walks for the public in and around České Budějovice.
