All plants take up carbon dioxide when they grow, but when they are harvested or cut down, they release the greenhouse gas back into the atmosphere.
Traditional market transactions ignore the costs of greenhouse gas emissions. An emissions trading scheme is a tool to put a price on emissions and to influence us to choose lower-emission options.
New Zealand is small and generates a tiny fraction of global greenhouse gas emissions, but investment in cutting emissions is important and could influence other, larger countries.
Plants live off carbon dioxide, but a higher level of the greenhouse gas in the air doesn’t necessarily lead to more biomass production.
Do you have a question about climate change? This collaboration between The Conversation, Stuff and the New Zealand Science Media Centre gives you the chance to ask – and we’ll provide expert answers.
