The GLOBE Climate Legislation Study examines how climate change is being addressed through legislation, to varying extents, in major economies. Although the approach differs, according to national priorities and circumstances, the study fins that overall country aims – to reduce GHG emissions and prepare the country for the impacts of climate change – are consistent. Given the projected increase in the global population, the authors of the report find it encouraging that much of the legislative activity is taking place in developing countries that, together, will represent 8 billion of the projected 9 billion global citizens in 2050.
