Environment macroeconomics, sometimes called environmental macroeconomics, is an interdisciplinary field that examines how environmental factors such as natural resources, climate change, and pollution influence aggregate economic performance, and how macroeconomic policy and institutions shape environmental outcomes. It combines macroeconomic theory with environmental accounting and ecological economics to analyze the links among gross domestic product, inflation, unemployment, investment, and the stock of natural capital.

Key concepts include natural capital and environmental depreciation, green accounting, carbon intensity, and resilience to environmental shocks. Economists study positive and negative externalities, resource constraints, and the uncertainty surrounding climate risks. Measurement challenges arise from valuing ecosystem services, nonmarket goods, and the depreciation of natural assets over time.

Policy tools and mechanisms include carbon pricing (taxes or cap-and-trade), subsidies and standards for clean energy and energy efficiency, regulation of pollution, and public investment in green infrastructure and research and development. Macroeconomic policy interacts with environmental policy through stabilization, debt sustainability, and long-run growth via productivity gains from technological change and resource efficiency. Transition risk and climate adaptation are increasingly incorporated into macro models, including at the international level.

Challenges and research directions include data limitations, attribution problems, and balancing growth with environmental protection and equity. There is ongoing work to integrate climate-economy models with macroeconomic frameworks (such as integrated assessment models) and to improve environmental data, forecasting, and policy evaluation under uncertainty.
