As anthropogenic carbon dioxide is being singled out as one of the culprits of global warming and climate change, there is an urgent need to increase and maintain vegetation and to educate the young generation about low carbon dioxide science economy, which will pave the way for a greener and more sustainable community. This paper describes two-fold activities, which are the learning process and the learning content (scientific). The learning process dealt on a problem/project-based learning approach developed by teachers in pilot project sites which focused on the integration approaches across curricula in the context of real-life scientific issues. The learning content, on the other hand, focused on calculation of carbon dioxide and other pollutants sequestration by trees. An experiential and discovery learning approach is a significant driver for shifting one’s perspectives and helps to develop responsible citizens who can manage a more sustaining environment.
