The correct option is indeed 1 and 2 only. The Global Climate Change Alliance (GCCA) is primarily an initiative of the European Union aimed at supporting developing countries in addressing climate change challenges.

Understanding these nuances in international environmental initiatives is crucial for UPSC aspirants, as they reflect the global commitment to sustainable development and climate action.
