The most obvious global link to this theme is Climate Change as this, the most serious environmental problem of our time, is intrinsically linked to energy use. The problems associated with Climate Change are vast, and they impact both the environment and people all over the globe, in particular people in developing countries. The Global Citizenship approach you will take throughout this theme will help you to discover how your efforts to reduce energy and tackle inequalities contribute to a global movement for more sustainable livelihoods, systems, and practices everywhere.
