O2 Initiative...

O2 civil initiative is about putting clean environment as priority to the government. We want to see systemic and sustainable solutions for the problem of pollution. We work towards higher environmental budget, higher efficiency in effectuating the change. We demand the local and central government to solve certain issues during their mandate. We want clean air, clean water, clean soil to be guaranteed and possible for us and the future generations. We want to pass the legacy to the next generations who are the ones to live the change we are working for today.
