Climate-conscious man travels 13,500 miles to China without taking a single plane

A climate-conscious man from the UK has traveled thousands of miles to China without getting on a single flight.

Setting off from Southampton, England, and heading to China, Roger Tyers opted for a plane-free trip despite traveling a whopping 13,500 miles to the East Asian country.

Roger Tyers documents his train journey from Moscow to Kiev as part of his wider trip to China:

The 37-year-old's journey, which he took in May, involved taking 24 trains across nine countries before he reached his final destination of Ningbo, a port city in China.

Tyers, who refers to himself as a research fellow at Southampton University on his Twitter bio, was traveling to the country in order to conduct academic research. In total, the trip cost more than £2,000 ($2,600 US), which is almost triple the cost of a return flight.

He told CNN that he decided to stop flying when UN climate experts warned last year that the world had less than 11 years to prevent irreversible damage from climate change.

According to Tyers, his train journey to China produced almost 90% less emissions than a return flight.

"It's hard to understand how polluting air travel is and the amount of energy and kerosene it takes to put people in the air and get them across the planet," he told CNN.

Of course, Tyers certainly isn't the only person who has pledged to stop flying. Indeed, Greta Thunberg, the teenage climate activist from Sweden who condemned world leaders for not taking enough action where tackling climate change is concerned, has vowed to reduce her carbon footprint by avoiding flights overseas.

This is the moment Greta Thunberg criticized world leaders at a climate summit at the United Nations in New York:

"People are suffering, people are dying, entire ecosystems are collapsing. We are in the beginning of a mass extinction and all you can talk about is money and fairy tales of eternal economic growth," Thunberg famously said in her profound speech.

"How dare you continue to look away and come here saying that you're doing enough when the politics and solutions needed are still nowhere in sight," she continued. "You say you hear us and that you understand the urgency, but no matter how sad and angry I am, I do not want to believe that. Because if you really understood the situation and still kept on failing to act then you would be evil and that I refuse to believe."

So, will you opted for a train to China on your next trip to Asia?
