Cycling is kind to the environment so it is an excellent way to take in the city. Here are 4bike-friendly cities having adopted this green mode of transport to reduce greenhouse gas emissions.
Montréal, Canada
Montréal has already established protected bike paths since the 1980s. BIXI is the city’s bike-sharing system with 9, 600 bikes and almost 800 stations. Cyclists can make their visit to the Tour de L’lle Montreal, a yearly bike ride where cyclists take to the streets for a day without any other vehicles being allowed on the roads.
Malmö, Sweden
Cycling in Malmö is enjoyable due to the relaxed and easy-going manner of most cyclists. The calming atmosphere makes it a great experience, even for nervous riders. A highly recommended bike route is from Ribersborg park to Limhamn Harbour, where riders can take a few good photos of the famous Oresund Bridge.
Beijing, China
In the 1970s, bicycles were the main mode of transportation for people in Beijing. However, dedicated (专用的) cycle paths for cyclists were limited. Only in May 2019, did the city launch its first specific cycle path. This achievement in cycling facility is worth a shout-out for a city with over 21 million people.
Bogota, Colombia
Bogota first introduced the concept of cycle path in 1974. The idea sees cars being banned from city roads every Sunday from 7 a.m.to 2 p.m., helping cyclists, runners and walkers exercise safely. Since then, the city has slowly but steadily expanded the program, including setting up dedicated cycle paths. As a result, Bogota now has 550km of bike paths and is the most bike-friendly city in Latin America.

2 . Electric cars are already greener than petrol cars in almost every part of the world today, according to researchers. They say electric vehicles are “a no-regret choice” even in places where power nets haven’t gone fully green.
Some previous comparisons suggested petrol cars produce lower net carbon emissions (净碳排放量) over their lifetime than battery- powered cars. Yet these analyses have often compared only two fixed models of cars.
Instead, the researchers from Radboud University looked at the average emissions across many classes of car to get a clearer global picture. It includes during its production, while it is being driven and when it is broken, for all the petrol and electric cars sold in 59 areas across the world in 2015. They connected with information of those areas in the following years and found that the electric vehicles are greener than the new petrol cars. Electric vehicles already have lower net carbon emissions in 53 of those 59 areas. Only in some countries that use coal heavily, such as India and Poland, are electric car emissions worse than those of petrol cars.
The researchers say that the differences between petrol and electric cars on the carbon emissions will grow bigger as power stations get greener. By 2030, they expect the carbon emissions of electric cars to be 20 percent lower than that in 2015, and 30 percent lower by 2050. The suggestions for governments are clear, says Knobloch.“There is no need to wait. Don’t be confused by all those different results out there. It’s a no-regret choice already.”
