The Economic Damage of Environmental Destruction - A Historical Perspective

The Economic Damage of Environmental Destruction - A Historical Perspective

The Situation in 2008
In 2008, the economic damage caused by environmental destruction was reported to have reached approximately US$660 billion (about 530 trillion yen), which is equivalent to about 11% of global GDP. Major causes include overuse of natural resources by human activities, deforestation, soil degradation, water pollution, and air pollution. In particular, the loss of carbon sequestration capacity and degradation of ecosystem services due to deforestation had a major impact.

At the time, the United Nations Environment Programme (UNEP) warned that if no action was taken, the damage could exceed four times the current level by 2050. It was predicted that the progressive collapse of ecosystems would have a serious impact on food production and the use of water resources, and there were calls for the introduction of sustainable energy, the strengthening of laws and regulations for ecosystem conservation, and the urgent implementation of a system to internalize the environmental costs of companies.

Current Status in the 2020s
In the 2020s, the economic damage caused by environmental destruction is becoming even more serious: data for 2022 report that the total global damage caused by environmental destruction exceeds US$10 trillion, or about 13% of global GDP. This increase is particularly pronounced in Asia, where urbanization and industrialization are progressing rapidly, and in China and India, air pollution and water resource depletion are serious issues.

In Japan, the effects of environmental destruction are becoming apparent in coastal areas such as Tokyo Bay and the Seto Inland Sea. Plastic waste is a particular problem. By 2021, the concentration of microplastics collected in Tokyo Bay will reach 5,000 per cubic meter, raising concerns about the impact on the ecosystem. Furthermore, heavy metal pollution is also serious, with cadmium concentrations in Kasumigaura, Ibaraki Prefecture, found to exceed twice the standard value at some sites.

Companies are also responding to the situation. Toyota Motor Corporation has set the "Toyota Environmental Challenge 2050," which aims to reduce CO2 emissions from new vehicles to zero by 2050, and is accelerating the introduction of renewable energy and the spread of electric vehicles. In addition, Sumitomo Chemical is focusing on product development with an emphasis on ecosystem conservation and promoting the use of bioplastics. Meanwhile, the EU has set a target of reducing greenhouse gas emissions by 55% from 1990 levels by 2030 under the European Green Deal, and is promoting measures such as the introduction of a carbon tax.

Conclusion
From 2008 to the 2020s, the economic damage of environmental destruction continues to increase. However, progress has also been made in measures taken by corporations and the international community, and this is a critical time for the transition to a sustainable society. It is essential that corporations, local governments, and the international community continue to work together to take concrete measures to address this issue.
