Do US GHG Emissions Commitments Pass Ethical Scrutiny? (Ethics and Climate, Jun. 16, 2015)
Now that the Pope’s encyclical has made ethics a major consideration for addressing climate change, the question is asked what level of reduction of carbon emissions is fair and ethical in order to keep the earth’s atmosphere below the accepted 2 degrees of warming? As 5% of the world’s population, the USA’s share of the required 270 gigatons carbon reduction would be 13.5 Gtc compared to the current emission rate of 1.44 Gtc/year and this, in turn, would point to a 95% reduction by 2050, not the 80% pledged by the USA in 2014. And this does not include the ethical issues of responsibility for the fate of developing countries which did not play a significant role by their carbon emissions in getting to the state of the world we are now in. Other developed countries with high emission rates need to consider their fair share as well, in the days and months leading up to the agreement on emission rates expected at the UN’s climate conference in Paris in December 2015.
