Carbon Farming Gets A Nod At Paris Climate Conference

• News & Highlights

This week, world leaders are hashing out a binding agreement in Paris at the 2015 U.N. Climate Change Conference for curbing greenhouse gas emissions. And for the first time, they've made the capture of carbon in soil a formal part of the global response to the climate crisis.

"This is a game changer because soil carbon is now central to how the world manages climate change. I am stunned," says André Leu, president of IFOAM — Organics International, an organization that promotes organic agriculture and carbon farming worldwide.

Leu is referring to the United Nations Lima-Paris Action Agenda, a sort of side deal aimed at "robust global action towards low carbon and resilient societies." On Dec. 1, countries, businesses and NGOs signed on to a series of new commitments under the agenda, including several on agriculture.

Currently, the Earth's atmosphere contains about 400 parts per million of carbon dioxide. Eric Toensmeier, a lecturer at Yale and the author of The Carbon Farming Solution, a book due out in February, says the atmosphere's carbon dioxide levels must be cut to 350 parts per million or lower to curb climate change.
