The new COP21 draft text, published at 15:00 today has dropped aviation and shipping! Under the previous draft, there was an optional clause requiring a limitation or reduction of greenhouse gas (GHG) emissions from international aviation and marine bunker fuels. This clause is nowhere to be seen in the new draft.
Aviation currently accounts for about 2% of the world's GHG emissions and predictions suggest this figure could grow by almost 400% by 2050 in the absence of regulation whilst international shipping is a significant and growing source of GHG emissions, with a predicted 50-250% increase between now and 2050. It goes without saying that the decision to exclude these industries from the global climate agreement substantially undermines its long-term impact.
