The document discusses the United Nations' involvement in addressing carbon emissions and global warming. Specifically:
1. The UN Environmental Programme aims to build green economies powered by clean energy, equip communities with resilience against climate impacts, and sustainably manage forests as carbon sinks.
2. While the UN strives for these goals, many countries take a more practical approach and issues exist with concepts like carbon credits. Carbon taxes could negatively impact car-producing countries or indebted countries with high-emitting industries like space flight.
3. The document provides scenarios about how carbon credit taxes might specifically impact different types of countries.
