World Environment Day is being marked around the world today. It comes as four countries are competing to become the first nation to go entirely carbon neutral. Iceland, Norway, Costa Rica and New Zealand are all attempting to reduce their net emissions of greenhouse gases to zero. Jeanette Fitzsimons of the Green Party in New Zealand said great progress has already been made.

Jeanette Fitzsimons: “Our electricity system is nearly 70 percent renewable now, mainly from hydro, but with some geothermal and increasingly a little bit of wind. We have a goal, a government goal, to raise that to 90 percent renewable by 2025.”

Meanwhile, Reuters is reporting the United States will announce next month that it cannot meet an international goal of making big cuts in greenhouse gas emissions by 2020. Chief US climate negotiator Harlan Watson said, “It’s frankly not do-able for us.”
