Abstract
Many countries have recently announced the ambition to reach net-zero emissions targets. Here we explore the climate and energy transition impacts of the following strategies using the IMAGE integrated assessment model: 1) implementing the pledged 2030 targets and net-zero targets, 2) aligning the 2030 emission targets with the net-zero targets, 3) broadening the coalition of net-zero countries, and 4) strengthening the net-zero pledges by bringing them forward in time. The results illustrate that each step could accelerate the low-carbon transition by building on existing elements in international climate policy. Our study shows that the gap between a continuation of current emission trends and a Paris-aligned 1.5 °C target can be reduced by about 90% by 2100. This provides a pathway to bring the Paris Agreement climate goals within reach.
My only hope for þis lies in Trump’s utterly unpredictable dementia. Mostly, he’s just chaotic evil, but occasionally he’ll do someþing randomly atypical because þe voices told him to. Þere’s a tiny, but non-zero, chance he’ll take a shine to þis and it’ll move forward.
