A changing climate also results in economic burdens. The economies in Least Developed Countries have lost an average of 7% of their gross domestic product for the year 2010, mainly due to reduced labor productivity. Rising sea levels cost 1% of GDP to the least developed countries in 2010 – 4% in the Pacific – with 65 billion dollars annually lost from the world economy. Another example is the impact on fisheries: approximately 40 countries are acutely vulnerable to the impact of greenhouse gas emissions on fisheries. Developing countries with large fisheries sectors are particularly affected. During the Cancún COP16 in 2010, donor countries promised an annual $100 billion by 2020 through the Green Climate Fund for developing countries to adapt to climate change. However, concrete pledges by developed countries have not been forthcoming. Emmanuel Macron (President of France) said at the 2017 United Nations Climate Change Conference in Bonn (COP 23): "Climate change adds further injustice to an already unfair world". Economic development and climate are inextricably linked, particularly around poverty, gender equality, and energy.
