Sure, here are the main ideas expressed in 30 words:
A. Aviation - refers to the transportation of people and goods by airplanes, which contribute significantly to greenhouse gas emissions that cause climate change.
B. Climate change - the long-term changes in Earth's temperature and weather patterns caused by human activities, including aviation emissions.
C. Measuring impact - understanding the magnitude of aviation's contribution to climate change through emissions inventories and impact assessments.
D. Proposing measures - developing and implementing solutions to mitigate aviation's impact on climate change, including technological and operational advances.
E. Green technologies - technologies that reduce or eliminate emissions, like electric and hybrid planes, or using biofuels instead of traditional jet fuels.
F. Eco-labeling - certifying products and services with environmental labels that indicate their eco-friendliness and help consumers make sustainable choices.
G. Source 3 by Gössling et al. - a research article that examines aviation's impact on climate change and proposes measures to mitigate it.
H. Examining impact of aviation on climate change - assesses the extent to which aviation contributes to climate change and identifies the most significant emissions sources.
I. Suggesting measures to mitigate the impact - proposes solutions to reduce emissions from aviation, such as green technologies, improving fuel efficiency, and eco-labeling schemes.
