Alaska Coal and Carbon Dioxide Emissions

Alaska has an enormous coal resource, and if this resource were heavily exploited and Alaska became a "coal superpower", Alaska's coal would make a tremendous contribution to global greenhouse gas emissions, primarily in the form of carbon dioxide (CO2).

2017-5-23 · According to the Alaskan Fire Emissions Database (AKFED) , biomass burning emissions were between 1.0 TgC⋅y −1 and 1.6 TgC⋅y −1 in 2012 and 2014, but reached 11 TgC⋅y −1 in 2013 , with emissions predominantly from boreal forests in interior Alaska. Nonbiogenic carbon emissions cancelled out biogenic carbon uptake in 2012, resulting in a small source of carbon [6.5 (−9.9, 26.2 95% CI)

CO2 emissions - Our World in Data

Carbon dioxide emissions are the primary driver of global climate change. It’s widely recognised that to avoid the worst impacts of climate change, the world needs to urgently reduce emissions. But, how this responsibility is shared between regions, countries, and individuals has been an endless point of contention in international discussions.
