Japan: Two Decades of Ecological Footprinting

Japan, home to the world’s most populous metropolitan area (Tokyo) and the fourth largest economy (by purchasing power parity), was an early adopter of the Ecological Footprint concept. The Ecological Footprint was first mentioned in an official Japanese government document in 1996, seven years before Global Footprint Network was founded. The early foothold in Japan can be credited to Yoshihiko Wada, Ph.D., a professor of economics at Doshisha University, who collaborated with Dr. Mathis Wackernagel on Footprint research in its early years and today is a member of Global Footprint Network’s National Accounts Committee.

Government Engagement

Most recently, the Japanese Ministry of the Environment’s 2018 Annual Report featured the Ecological Footprint results for Japan and highlighted Global Footprint Network’s Kyoto city project, completed in collaboration with IDEA Consultants and WWF Japan (pages 68-70). The report noted that if everyone in the world lived like residents in Kyoto, we would need two Earths. This metric would drop to 1.4 Earths if Kyoto achieves its goal of reducing greenhouse gas emissions 40% in 2030 from 1990 levels.

Japan’s Ministry of the Environment first included the Ecological Footprint in its 1996 Annual White Paper, which was the first major step by the national government to take action on sustainability. Since then, the Footprint has been a key indicator in several of Japan’s sustainability campaigns. Highlights (in chronological order) include:

  • The major metropolitan area of Tokyo released the “Tokyo Metropolitan Government Environmental White Paper” in 2000 and estimated that Tokyo needed 125 times its area to support its citizens. This report marked the first time a city in Japan used Ecological Footprint accounting to calculate its natural resource consumption and make strides to change its trajectory towards one planet living.
  • Japan’s Ministry of Land, Infrastructure, and Transport and National and Regional Planning Bureaus calculated the Ecological Footprint of Japan’s 47 prefectures in a 2003 joint report. This effort marked the first time the Footprint was used at a subnational level to help regional agencies understand their resource constraints.
  • The Ecological Footprint was adopted by the national government as part of Japan’s Basic Environmental Plan in 2006 and featured strategies for pursuing a more sustainable society and policies for developing diverse energy sources.
  • Global Footprint Network supported IDEA Consultants Inc. in the report released by the Ministry of Environment in 2016. The report, the Comprehensive Assessment of Biodiversity and Ecosystem Services (JBO2: Japan Biodiversity Outlook 2), acknowledged the Ecological Footprint in analyzing ecosystem services and human well-being.
  • Kyoto City became the first local government in Japan to calculate its own Footprint in 2016 as part of a joint project involving IDEA Consultants, WWF Japan, and Global Footprint Network. Results in the report showed that the carbon Footprint accounts for 64 percent of the total Ecological Footprint and that if everyone lived like the average Kyoto resident, we would need two planets. The report also set an ambitious goal for Kyoto to reduce carbon emissions 40 percent by 2030 in order to reduce its Ecological Footprint.

Public awareness

To amplify the efforts of the Japanese government to use the Ecological Footprint in policymaking, Global Footprint Network teamed up with organizations such as WWF Japan to help raise sustainability awareness through several campaigns.

  • The 2010 Ecological Footprint Report found Japan’s Ecological Footprint exceeded the world average by a whopping 50 percent. The report included policy recommendations for decision-makers and tips for consumers to help change consumption patterns and reduce carbon emissions.
  • The 2012 Ecological Footprint Report updated Japan’s data to track its progress toward living within the means of our one planet. The report also tracked Footprint trends to historical milestones, and compared the Footprints of Aichi, Okinawa and Tokyo.The report also analyzed the impact of the Fukushima nuclear disaster on biocapacity, estimating it rendered between 2.7 percent and 10 percent of the country’s biocapacity unproductive. Another striking result was that 20 percent of Japan’s Ecological Footprint is associated with food consumption. The report reiterated the need for governments, nonprofits, and consumers to work together to reduce carbon emissions and resource consumption.
  • “The Ecological Footprint for Sustainable Living in Japan” (2014) was distributed to the general public to inspire individuals to change behavior, such as reducing food waste, and focus attention on policy change, such as a shift to renewable energy, to reduce the country’s Ecological Footprint.
  • In order to raise awareness about the Footprint as a policy-making tool, Global Footprint Network partnered with IDEA Consultants Inc. in 2014 and collaborated on six projects centered on incorporating the Footprint in business, policy-making, and education decisions.
  • The Japanese electric company Fujistu created an environmental education tool with WWF Japan and Global Footprint Network’s support. Research Economist Katusnori Iha also (center image below) has taught students about the Ecological Footprint.

  • The “How many Earths does your city need” (2019) brochure was created for local governments to introduce the Ecological Footprint concept and demonstrate its use in environmental policy and city planning. This brochure builds upon “The Ecological Footprint for Sustainable Living in Japan” from 2015 that focused on the general public.
  • As part of the FEAST Project (Lifeworlds of Sustainable Food Consumption and Production-Agrifood Systems in Transition), Global Footprint Network computed the Ecological Footprint for Japan’s 47 prefectures. The analysis included a breakdown of the Ecological Footprint by demographic or other socio-economic indicators. The FEAST project takes a transdisciplinary approach to explore the reality of, and potential for, sustainable agrifood transition in Asia (Japan, Thailand, Bhutan, and China). Outcomes of the project are detailed in “Decentralization & local food: Japan’s regional Ecological Footprints indicate localized sustainability strategies” recently submitted to the Journal of Cleaner Production (awaiting press). The five-year collaboration (2016-2020) culminates this year, so stay tuned for final highlights from the project!

Business Footprinting

After the Footprint gained traction with government policy makers, businesses began using the concept to help fully understand their environmental impact.

Long-term relationships characterized by mutual respect with our partners have been crucial to the success of Global Footprint Network’s work in Japan. Global Footprint Network looks forward to continued collaboration with these partners in the future and also welcomes inquiries from new potential partners to further amplify our work.
