Since entering office on Monday, Trump has already:

• Withdrawn from the Paris climate agreement
• Declared a national energy emergency, promising to “unleash” US energy production, roll back restrictions on drilling in Alaska and increase gas exports
• Ended the Green New Deal, a series of Biden measures that were aimed at boosting green jobs, regulating the fossil fuel industry and limiting pollution
• Revoked electric vehicle targets, which would have made half of all new vehicles sold in 2030 electric
• Left the World Health Organization
