A tax credit is a dollar-for-dollar reduction in a taxpayer’s tax liability. Green tax credits, also known as clean energy tax credits or renewable energy tax credits, are government incentives designed to encourage individuals and businesses to invest in environmentally friendly technologies and practices. By lowering the cost of clean energy and energy-efficient upgrades, green credits encourage investment in renewable energy, energy efficiency, and other environmentally beneficial projects. A sustainable business, or a green business, is an enterprise that has (or aims to have) a minimal negative (or potentially positive) impact on the global or local environment, community, society, or economy.
