A green skill or sustainable skill refers to the knowledge and abilities people need to support environmental sustainability in the workplace and the economy. These skills include things like energy efficiency practices, sustainable agriculture, waste reduction, renewable energy technology, and environmental compliance. They are becoming essential across many industries, not just in traditional "green" jobs because of growing demand for environmentally responsible practices in sectors like construction, manufacturing, transportation, and education. Developing green skills helps prepare learners and workers for careers that contribute to a low-carbon, resource-efficient future.
