The most commonly used fossil fuels are coal, oil and natural gas, primarily serving as sources for heating, fuel and electricity production.

When fossil fuels are used, they release gases known as greenhouse gases. When these gases accumulate beyond natural levels, they cause the Earth's atmosphere to warm up, leading to global warming and, consequently, to climate events that threaten the ecosystems of all life forms, including humans.

Supporting initiatives that promote development and widespread use of renewable energy sources and investing in this field to replace fossil fuels with clean energy alternatives such as solar, wind, and wave power are steps that can be taken both individually and globally.
