為什麼要關注運輸？
運輸佔全球溫室氣體排放量的16％” 
。 如果我們希望減少個人排放，這是一個很好的起點。
Emissions vary depending on what you use to travel
Flying creates 2.4% of global CO₂ emissions ! But this is only part of the story - over half of its climate impact comes from non-CO₂ emissions .
For example, planes release trails of water vapour which produce clouds that trap energy from the sun, creating a warming effect three times that of CO₂ !
飛行的影響
你如何減少飛行對環境的影響？
對於某些旅程，除了乘飛機外，還有其他選擇，例如乘火車或渡輪。
如果無法做到這一點，那麼經濟艙飛行是下一個最佳選擇。 飛機公務艙的二氧化碳排放量是經濟艙的2至3倍，而頭等艙的二氧化碳排放量是公務艙的2至3倍！ 這是因為高級座位佔用了更多空間。

來自汽車的排放
在歐盟，公路運輸（包括汽車，卡車和公共汽車）佔運輸總排放量的72％！
也就是說，最好的選擇是乘坐公共交通工具，步行或騎自行車。
Riding together can lower your impact!
你應該買一輛電動車嗎？
Electric cars get their energy from electricity in a battery, rather than fuel in a tank .
不幸的是，大多數地方仍然通過燃燒\definition {化石燃料}{fossil fuels} 來發電。
與傳統的汽油車相比，電動汽車在其使用壽命中仍產生較少的排放物。
Electric vehicles have a lower impact than conventional vehicles
Even in the US, where 84.3% of energy is produced by fossil fuels , electric vehicles emit half as much as petrol vehicles .
That said, electric cars still cause the same problems associated with all cars: traffic and road accidents .
Plus, cars release particles called PM₂.₅, which cause air pollution in cities . Most of these don’t come from the exhaust, but from friction in the breaks and the tyres, so occur on any type of car .
Where do emissions from electric cars come from?
結論
We can all play a role in reducing our emissions by limiting how much we travel as well as choosing transportation options with a lower carbon footprint .
You’ll reduce your impact by taking public transport!
現在你可能在想：「我可以減少自己的碳足跡，這很不錯，但是因為我只有一個人，它不會改變任何東西。」 這是一個重要的問題，我們接下來將進行探討！
