In recent years, Japan has experienced frequent major typhoons, intense rainfall events, and record‑breaking heat—phenomena that are no longer “abnormal,” but “normal.” These are unmistakable effects of climate change. Now more than ever, each of us must reconsider how we use energy and resources, and choose more sustainable options.

What is a carbon footprint?
A carbon footprint is the total amount of greenhouse gases emitted from your daily life. It’s expressed in CO₂e (carbon dioxide equivalents), allowing you to quantify your environmental impact. Use this tool to understand how your actions affect the Earth, and begin your steps toward a sustainable future.

On average, a person in Japan has a carbon footprint of about 7,000–7,500 kgCO₂e per year ^{(ref. 30, 31),} which is relatively high compared to many countries worldwide. Country‑to‑country differences are significant, but Japan’s per‑capita footprint is particularly high.
Learn your personal footprint and start taking action toward a sustainable future.
