Study suggests NZ's ETS could be more effective in emissions reduction if five key sectors are better regulated.

New Zealand's Emissions Trading Scheme (ETS) could have a greater impact on the country's emissions reduction goals if five key sectors—agriculture, transport, energy, petroleum and diesel, and waste—are better regulated, according to a study by University of Auckland researchers. The study finds that while the ETS effectively reduces emissions on a broad scale, it fails to spur economic expansion and curtail emissions simultaneously.
