Some environmental groups, including the Union of Concerned Scientists and Friends of the Earth, had hoped that more permits would be auctioned from the start and that a greater proportion of auction revenues would be dedicated to renewable energy investment and international climate mitigation and adaptation efforts.
Ilang environmental group, kabilang ang Union ng mga Nag-aalala siyentipiko at mga Kaibigan ng Earth, ay inaasahan na ang higit pa permit ay auctioned mula sa simula at ang isang mas mataas na bahagdan ng kita sa auction ay nakatuon sa renewable enerhiya investment at pang-internasyonal na pagpapagaan ng klima at mga pagsusumikap sa pagbagay.
