Global greenhouse gas emissions from human activity have increased significantly since the preindustrial era, driven by socio-economic progress and population growth. This has led to unprecedented atmospheric concentrations of greenhouse gases (GHGs) recorded over the last 800,000 years (IPCC 2014a). The increase in atmospheric GHG concentrations leads to global warming and climate change. Climate change is increasingly felt around the world, with negative impacts affecting more and more people worldwide. As a result global attention to climate change has increased significantly over the past decades, and more and more countries, businesses and individuals are discussing, demanding, and taking, climate action.
