In 2023, Japan's government expenditure on R&D in the environment stood at 263.73 million USD PPP. From 2024 to 2028, a consistent upward trend is forecasted, with expenditure increasing modestly each year. Specifically, from 2024 to 2025, there's a projected rise of approximately 1.11%, followed by a similar annual growth pattern until 2028. Over the five-year period, the compound annual growth rate (CAGR) is relatively steady yet conservative.
Future trends to watch for include Japan's potential increase in environmental R&D funding if global environmental policies and agreements demand faster technological advancements or if new green technologies present significant breakthrough opportunities. Additionally, shifts in political priorities or economic conditions could alter funding trajectories.
