CO2 Emissions and Indicators up to 2020 and Necessary Scenario for Compliance with the 2-Degree or 1.5-Degree Target

A scenario compatible with the 2-degree and 1.5-degree targets up to 2050 for the USA is shown in Fig. 3.1. The decrease in 2020 is primarily due to the Corona pandemic. The corresponding course of the indicators is depicted in Fig. 3.2. The trend of energy efficiency (energy intensity) must be maintained at least until 2030, and that of the CO2 intensity of energy, especially for the 1.5-degree target, needs to be significantly improved. Analyzed are also Canada, Mexico, Rest of Central America, Brazil and Rest of South America
