Anthropogenic (human-caused) emissions of global greenhouse gases, including carbon dioxide (CO2), methane (CH4), nitrous oxide (NO2) and F-gases, lead to an increase of the concentration of greenhouse gases in the atmosphere, which in turn causes atmospheric warming by trapping heat in the atmosphere (greenhouse gas effect). Atmospheric warming leads to climatic changes causing more frequent and extreme weather events and higher temperatures globally, leading to large impacts across the globe and particularly in developing countries that often have a limited means to adapt and build resilience. The international scientific community has warned that emissions need to decline to net zero by the middle of the 21st century to limit global warming to well below a 2deg C increase and help avoid the most consequential climate change impacts. 

Climate change is having a disproportionate impact on developing countries and if unabated will not only reverse past development progress and hinder poverty reduction but will also make future development more costly. Country level assessments of the potential climate change impacts on specific developing countries, performed as part of the World Bank’s Country Climate and Development Reports (CCDRs), show that climate change will have a significant impact on developing countries’ economies, ranging from about 0.5% of GDP for higher income developing countries to over 13% for the lowest income developing countries. The costs of partial adaptation to these changes will be significant as well -- ranging between 1 and 10% of developing countries’ GDP.
