As an international, global organization, Greenpeace focuses its attention on influencing both the public and policymakers of the dangers behind the unrestricted mining and use of fossil fuels. As a regional organization, Greenpeace Southeast Asia focuses on bearing witness to the impacts of global warming, and increasing public awareness of the problems it poses. Greenpeace SEA also seeks to effect changes in the direction of the region's energy policies for the future - moving from fossil fuel dependency towards embracing renewable, clean and sustainable sources of energy.

The Climate and Energy Campaign's tactic is to confront the challenges posed by the fossil fuel industry - in particular, coal-fired power plants and nuclear-based energy - while, at the same time, articulating and pushing for solutions to fossil fuel dependency. For instance, Greenpeace SEA promotes policies and projects that favor energy generated by wind and solar power, and advocates for energy efficient alternatives.
