The forecast for the US government’s environmental R&D budget from 2024 to 2028 indicates a slight decline as a percentage of total government R&D expenditure. Starting at 0.31% in 2024 and steadily decreasing to 0.29% by 2028, this forecast represents a gradual reduction. This decreasing trend reflects a shift in funding priorities or possible budgetary constraints. In 2023, the level was presumably higher than the values observed in 2024.

Future trends to watch for include:

Potential shifts in political climate that may impact funding priorities.
Emergent environmental challenges that could necessitate increased R&D investment.
Technological advancements that could drive changes in spending focus.
