Japan’s greenhouse gas declines for the fourth consecutive year in FY17 The goal of the Paris Agreement requires further reduction efforts

On November 30, the Ministry of the Environment and the National Institute for Environmental Studies announced “preliminary figures” that the domestic emissions of greenhouse gases such as carbon dioxide (CO2) in FY2017 were 1,294 million tons (CO2 equivalent). It decreased by 1% from the previous year, the fourth consecutive year of decrease. A ministry official said that while the introduction of renewable energy has been expanded, it is necessary to accelerate emission reduction measures in order to achieve the goals of the Paris Agreement, an international framework for global warming countermeasures. It is said.

According to the announcement, total greenhouse gas emissions in FY2017 were 1,294 million tons (CO2 equivalent, 1.0% decrease from the previous year, 8.2% decrease from 2013, and 6.2% decrease from 2005. In addition to the expansion of the introduction of renewable energy such as power generation and wind power generation, some nuclear power plants have restarted and the ratio of non-fossil fuel to the domestic supply of energy has increased.

The government has set a short-term target of “reducing by 3.8% in FY2020 compared to FY2005,” but this target has been achieved in FY2017. On the other hand, in the Paris Agreement, Japan has set a goal of “26% reduction in 2030 compared to 2013”, and there is still a big difference from this goal.

Looking at CO2 emissions, which account for the majority of greenhouse gases, by emission sector, the energy conversion sector (power plants, etc.) decreased by 4.6%, the largest decrease rate, and the industrial sector (factories, etc.) was 1.5. The transportation sector (automobiles, etc.) was down 0.9%, but the household sector was up 1.8%. Regarding this factor, the Ministry of the Environment cites an increase in the use of petroleum products such as kerosene at home.

The “breaking news” was announced this time, and the “fixed value” was announced in April next year, and the numbers may fluctuate slightly. The final value is the official value to be submitted to the Secretariat of the United Nations Framework Convention on Climate Change.

Regarding the Paris Agreement, the 24th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP24) opens on December 2 in Poland. Discussions will be held on the creation of detailed implementation rules for the agreement.Negotiations are expected to be difficult due to disagreements between developed and developing countries regarding implementation rules.
