The tree-lined path to carbon neutrality

摘要

The Carbon Neutrality Challenge is an initiative to mitigate climate change, in which individuals estimate their C〇_2 footprint and then plant enough trees to offset it. Thousands of trees have been planted by volunteers in Hawaii who took the CarbonNeutrality Challenge.Even with a full implementation of the Paris Agreement, maintaining global warming below 2 oC before 2100 might not be attained. Thus, averting the threat of climate change will require some degree of luck in discovering new technologies, or a considerable improvement of existing methods that reduce and/or capture carbon emissions. Planting trees for carbon offset, as an example, sounds simple, but this approach faces numerous technical problems for it to be successful at globally-relevant scales.
