Ford also states that the UNFCCC has evolved to address ‘exposure to predicted climate change impacts’ by stressing the need to adapt. Vulnerability based policy is regionally or socioeconomically specific policy aimed at reducing the disproportionate impacts of climate change on certain groups. This policy is emerging in developing countries in the global south, where communities are more impacted by climate change and environmental disasters. In the Kyoto Protocol, the Least Developed Country fund and Special Climate Change fund were established to improve development and adaptation in regions least equipped to manage the consequences of climate change. This form of policy has also been linked to sustainable development in developing countries. In vulnerable arctic regions, climate policy has increasingly focused on addressing changing weather patterns, animal demography and sea ice levels. In the late 2000s, the political discourse regarding climate change policy became increasingly polarising. The political right has largely opposed drastic climate policy while the political left has favoured progressive action to address environmental anomalies. In a 2016 study, Dunlap, McCright, and Yarosh note the ‘escalating polarisation of environmental protection and climate change’ discourse in the USA. In 2020, the partisan gap in public opinion regarding the importance of climate change policy was the widest in history. The Pew Research Center found that, in 2020, 78% of Democrats and 21% of Republicans in the USA saw climate policy as a top priority to be addressed by the President and Congress. In Europe, there is growing tension between right-wing interest in migration and left-wing climate advocacy as primary political concerns. The validity of climate change research and climate scepticism have also become partisan issues. Developing nations have commented that climate change and climate change policy disproportionately impact vulnerable states. Ford mentions that international climate policy does not adequately address the different needs and capacities of Annex 1 and Annex 2 states. The New Delhi Declaration of Principles of International Law Relating to Sustainable Development (2002) suggests that developing countries are both more impacted by and less equipped to address climate change. The Declaration also restates the concept of common but differentiated responsibilities. Gupta suggests that these disproportionate impacts justify lowering emission reduction targets for developing nations. Critics of equity-based policy have argued that it is “unfair” to create differentiated emission targets. There is debate over whether policy has addressed the gendered impacts of climate change. Röhr and Hemmati suggest that climate policy does not consider how mechanisms and instruments for change impact women. This inequality is prominent in the global south. A UNEP report suggests that women are more impacted by climate change and climate policy because they have less access to resources and because environmental disasters amplify preexisting 'power imbalances' in the global south.
