Berger predicts a 24% CO 2 share for aviation by 2050 if fuel efficiency improves by 1% per year and if there are no electric or hybrid aircraft, dropping to 3–6% if 10-year-old aircraft are replaced by electric or hybrid aircraft due to regulatory constraints, starting in 2030, to reach 70% of the 2050 fleet.

This is the market for shipping pollution. The optimal quantity and the optimal tax per unit of pollution can be found at the intersection of MAC and MD. As the quantity of pollution decreases (emissions), the cost to decrease each marginal unit of pollution increases. Since 2009, UPS deliveries have increased by 65%. [49]

Air pollution can occur naturally or be caused by human activities. [4] Air pollution causes around 7 or 8 million deaths each year. [5] [6] It is a significant risk factor for a number of pollution-related diseases, including heart disease, stroke, chronic obstructive pulmonary disease (COPD), asthma and lung cancer.
Airbus and Boeing are working on 17,000 new aircraft orders, but only 1,254 will have been delivered under current projections (30% less than forecast for 2024). In 2018, for example, airlines ...
Due to air pollution causing more than one effect it is hard to attribute a condition only to air pollution or to say how much a given source is responsible. However, it is believed that around 100,000 to 200,000 human deaths are attributable to air pollution [ 25 ] and at least a quarter are due to transportation. [ 26 ]
