But the problem of population growth and higher overall populations in emerging economies adopting more energy intensive lifestyles remains. These economies and their citizens are likely to use an enormous amount of cheap energy to grow their economies: Global energy demand is forecasted to rise by 30% as of 2040[119] because energy demand and thus per capita carbon footprints increase in proportion to income.
Also, xarbon tariffs (or border carbon adjustments) might prevent some, but not all,[152] carbon leakage and reduce emissions but are very difficult to calculate and lower trade flows and welfare, especially in emerging economies.[153]
