CLIMATE CHANGE AND ENERGY

Key Message
By 2030, the world's energy needs are expected to be 50 per cent greater than today. At the same time, scientists are calling for a 25 per cent reduction in greenhouse gas emissions by 2050 to avoid serious changes in the Earth's climate system. Reconciling these demands while simultaneously adapting to the impacts of climate change is one of the fundamental challenges of the 21st century.
