• The 10% of households with the highest per capita emissions contribute 34–45% of global consumption-based household GHG emissions. This means that a small number of people are responsible for a disproportionately large share of global emissions. This is because these households tend to consume more energy and goods, which produce more emissions.
• Least Developed Countries (LDCs) and Small Island Developing States (SIDS) have much lower per capita emissions than the global average. This is because these countries are less developed and have lower levels of energy consumption. However, it is important to note that these countries are also the most vulnerable to the effects of climate change.

Overall, it is clear that the historical and current contributions of CO2 emissions vary substantially across regions. This has important implications for climate change mitigation and adaptation efforts. It is important to ensure that all countries take responsibility for their emissions, and that the most vulnerable countries are supported in adapting to the effects of climate change.

Here are some additional things to consider:

• The gap between rich and poor countries in terms of CO2 emissions is widening. This is because the developing world is rapidly industrializing and increasing its energy consumption.
• The poorest countries are the most vulnerable to the effects of climate change, even though they contribute the least to emissions. This is because they often have weak infrastructure and limited resources to adapt to climate change.

It is important to address the historical responsibility for climate change in a fair and equitable way. This means that developed countries need to take the lead in reducing emissions, and that developing countries need to be supported in their efforts to do so.
