The correct answer is 1 and 2 only.

The Global Climate Change Alliance (GCCA) is an initiative of the European Union (EU) to strengthen dialogue and cooperation on climate change with developing countries. Therefore, the first statement is correct.

The GCCA provides technical and financial support to targeted developing countries to integrate climate change into their development policies and budgets. This support is aimed at building capacity and resilience in the most vulnerable countries, particularly those that are most exposed to the negative impacts of climate change. Therefore, the second statement is also correct.

However, the third statement is incorrect. The GCCA is not coordinated by the World Resources Institute (WRI) and World Business Council for Sustainable Development (WBCSD). In fact, the GCCA is coordinated by the European Commission`s Directorate-General for International Cooperation and Development (DG DEVCO).

The GCCA was launched in 2007 and has since supported more than 80 countries in Africa, Asia, the Caribbean, and the Pacific. The initiative focuses on five priority areas: i) adaptation to climate change, ii) reducing emissions from deforestation and forest degradation (REDD+), iii) enhancing capacity to measure, report and verify emissions, iv) supporting access to clean energy, and v) building resilience in the face of climate change.

In conclusion, the Global Climate Change Alliance (GCCA) is an initiative of the European Union (EU) that provides technical and financial support to targeted developing countries to integrate climate change into their development policies and budgets. It is coordinated by the European Commission`s Directorate-General for International Cooperation and Development (DG DEVCO), and focuses on five priority areas aimed at building capacity and resilience in vulnerable countries.
