The global climate change summit starts soon, Newsroom reports. Commitments by governments might disappoing, but civil society, the private sector and new technologies might not, says Adrian Macey, the former veteran New Zealand climate diplomat. “What is your transition plan should be a much more important question to ask countries,” Macey says. “Not how much money you’re giving to developing countries…or what are your targets by year X or Y?” Cutting short-lived methane is only valid if there are simultaneously large reductions in C02, because it is the levels of that long-lived gas which will determine our climate future, he adds.
