Greenhouse Gas Reduction


Aiming at solving global environmental issues through our engineering business, TOYO has worked on projects that utilize the CDM (Clean Development Mechanism) and JI(Joint Implementation), which have been established to reduce climate change.


Emissions Trading of Greenhouse Gases

CDM is one of the mechanisms for emissions trading of greenhouse gas that has been agreed upon under the Kyoto Protocol (so-called Kyoto Mechanism). When an industrialized country carries out a project in a developing country that leads to a reduction in CO2 and other greenhouse gases. The mechanism allows the industrialized country to be given a credit for the amount of CO2 reduced in the project, with respect to the emissions of greenhouse gases allocated to each country under the Kyoto Protocol. JI applies the same mechanism among industrialized countries.

Our Efforts

TOYO has worked on CDM/JI projects to reduce nitrous oxide emitted from nitric acid plants. Nitrous oxide is also known as laughing gas, and is represented by the chemical formula N2O. It is not harmful in any way to the human body when emitted at normal levels, but its global warming potential is 310 times that of carbon dioxide. For this reason, there is an urgent need to reduce its emission.
As a technical advisor and system integrator for the project developer on the Japan side, and the plant owner of the host country, TOYO has supported projects for decomposing nitrous oxide using catalysts. Through the several CDM/JI projects in which TOYO participates, over one million tons of emission credit will be generated each year. This helps to achieve Japan's target for the reduction of greenhouse gas emissions.

In addition to reducing nitrous oxide, TOYO has actively pursued emission reductions of greenhouse gases in developing and introduced energy saving technologies and flue gas carbon dioxide recovery technologies.
