Outgoing environment minister Guilbeault questions Carney's market-based climate solutions, defends political career

Steven Guilbeault, Canada's outgoing Liberal environment minister, reflects on his transition from activist to politician, defending his decision to work within government despite criticism. He acknowledges becoming 'a tool to justify some of the things the government is doing' and expresses skepticism about Mark Carney's market-based approach to climate change. Guilbeault argues that carbon markets and offsets have historically failed and that government regulation is essential. He leaves as several major environmental policies he helped develop face uncertainty, but encourages young climate activists to consider entering politics to effect change from within.
