18 : Solution Governments can tax greenhouse gas emissions, subsidize energy efficiency and renewable energy use, and cooperate internationally, and individuals and institutions can sharply reduce their greenhouse gas emissions. We can slow the rate of climate change by increasing energy efficiency, relying more on renewable energy resources, and reducing greenhouse gas emissions.
