The Importance of Enterprise Power in Climate Change Measures

Implementation of the Paris Agreement requires drastic reduction of greenhouse gases (GHGs) produced by social and economic activities as well as adaptations to the impacts of existing climate change. In order to achieve the "2℃ target" as described in the Paris Agreement, pursuing the global reduction of GHGs through innovative enterprises is absolutely critical. Promoting investments and enhancing cooperation to ensure climate financing through various non-state stakeholders such as private sectors, local governments, and civil societies are essential to the success of this global mission.

The international trends and aspirations for a low-carbon society are indisputable. Japanese companies have recognized these trends and have contributed to tackling climate change and realizing sustainable society through their own goods and services. The Ministry of Foreign Affairs (MOFA) is introducing several measures taken by Japanese companies, which can be found on this page. The pivotal role of the private sector was reviewed at the One Planet Summit (held in France, December 2017) and it was determined that although public finance will continue to be an important player in future ventures, the development of a sustainable society resilient to climate change is increasingly depending on the mobilization of private funding. Minister Kono, who participated as a panelist, expressed Japan's determination to lead the international community in increasing the scale of climate finance through its advanced technology and innovation. The Japanese Government is continuing to foster its partnership with the private sector to ensure the steady implementation of the Paris Agreement.
