The true cost of carbon offsetting. A plant owned by India’s energy giant Reliance Power may become the largest coal power project awarded carbon credits under the UN’s Clean Development Mechanism (CDM) — which lets industrialized countries offset their pollution by investing in greenhouse gas reducing projects in developing nations. But village communities are displaced to make way for plant construction; villagers are excluded from decision making and promises made to villagers of free education, employment and health care are never delivered. Critics say the project shifts investment away from renewable energy and supports coal – a leading cause of carbon emissions. A report by The Ecologist Film Unit.
