Being the world’s largest greenhouse gas emitter and second largest economy, China’s role in international climate negotiations has been the topic of much heated debate over the past 10 years. However, few studies have sought to understand China ́s role in the Global Environmental Governance and Chinese leadership therefore remains a lacuna in need of further investigation. This generates one central question: How does leadership theory bring insight into China ́s role in the international climate change negotiations? The research is designed as a qualitative case study, applying an analytical framework by Young (1991). A content analysis in conjunction with the analytical framework is applied to policy documents, speeches and official reports produced by the Chinese Government, UNFCCC and IISD as a way to understand China ́s negotiation strategies and climate change goals. The findings suggest that China has shown weak leadership during the climate summit in 2009, since there was a huge lack of leadership capabilities applied in their negotiation strategies. However, in 2015 China met all leadership indicators to a certain degree and can therefore be seen to have exercised strong leadership capabilities. It can therefore be argued, that China has become a leading actor in the climate change regime due to their shift in negotiation approach from 2009 to 2015, through their influence and position in shaping the global climate change agenda.
