Transportation represents over one quarter of the world's energy consumption and emissions of greenhouse gases. The number of vehicles on the road (700 million in 2005) [3] has increased tenfold in the last 60 years. The car is the most prevalent form of motorized transportation, ahead of bus and train. Airlines transport over 2.5 billion people a year [4], and represent two to five percent of all global green house gas emissions.
Today's business and leisure travelers face numerous opportunities to reduce their negative impact on the environment. The first step is to understand how each transportation mode affects the environment, and then try to minimize pollution and carbon dioxide emissions by making the best possible choices for your particular travel circumstances and preference.
Some important considerations for your journey are:
When choosing the form of transport, consider the following:
Having explored the various travel options and transportation alternatives, we can now explore each one of them in more detail.
In 2009, 2.5 billion people traveled by plane worldwide. Flying is a time efficient way of traveling, however airplanes are very fuel intensive and produce considerable amounts of carbon emissions, pollution and noise. The airline industry has recognized these environmental concerns and has been actively addressing them for decades. Airlines work closely with:
Although airlines have progressively increased fuel efficiency, reduced noise, pollution and carbon emissions, until an alternative to jet fuel is found, air travel will continue to be the largest part of your travel footprint.
There are nevertheless, several things you can do to travel smarter by air:
Whether you use your own car to embark on a road trip, or rent a vehicle abroad, there are many green driving tips that will assist you to cut down fuel consumption, greenhouse gas emissions and save money on the way
The good news is that the auto industry is continuing to develop more fuel efficient cars, as well as alternative fuel technology. Many car rental agencies are therefore upgrading their fleets, and hybrid and electric vehicles are becoming more widely accepted.
Renting a car with the environment in mind includes:
Some general green driving tips include:
Research has shown that one full coach has five times less carbon dioxide emissions, per passenger per kilometer, than a jet aircraft on the same route. For every full coach, there are 16 fewer cars on the road. This makes bus/coach transport a very environmentally efficient mode of transport [5].
Intercity Coaches are a green alternative to cars as they carry more people across long distances. Modern coaches are fuel efficient and are often equipped with toilets, onboard entertainment, and offer express routes.
Public Buses are often seen as a budget-conscious mode of transport in some countries, but they provide an environmentally friendly option that allows you to learn more about the local community's way of life.
Shuttles allow you to hop aboard mini-vans with passengers headed to the same hotel or attraction. You will save money by sharing the ride and won't have to worry about getting lost.
As a form of mass transport, trains have the potential to be an efficient and environmental way to travel. Many countries have extensive rail networks, which allow for intermodal connectivity between airports and urban centers, substantially reducing car traffic.
As operational efficiencies, route networks, and environmental best practices vary widely around the world, be sure to check train company websites to see what they are doing about sustainability in their country, and choose those that advertise their green efforts.
There are of course other benefits to train travel; it is generally cheaper than flying, it uses less fuel than air travel, cities and regions can be explored in a slower and more relaxed way, it supports national rail systems which employ people from the area, and it is used by locals and tourist alike.
Traveling by sea on a cruise ship, taking a passenger ferry, or lazily drifting on a river boat, are all great ways of exploring the world.
However, the environmental and socio-economic impact of the various marine sectors has not been clearly established. The responsible traveler should research more into sustainable best practices in water transport, especially large cruise ships, if are considering booking a sea-bound vacation.
Over 13.5 million people worldwide took a cruise in 2009, making the cruise industry a mass form of tourism [6]. Inevitably, such high passenger volume raises concerns about the impact of large vessels at sea and in ports. The cruise sector acknowledges the issues related to pollution and waste and is making industry-wide efforts to implement a range of initiatives aimed at minimizing its environmental impact, support conservation of marine ecosystems, and work to improve the livelihood of the communities in which they operate.
These include:
For those who love the sea, there are also small cruise line options, sailing, and yachting.
Bicycles are four to five times faster than walking, and in traffic jams, faster than motor vehicles! Bicycles provide the most efficient human powered form of transport, they are economical, environmentally sustainable, and provide an incredible opportunity to explore off the beaten track and share real life experiences with the locals.
Bike tours have gained popularity in recent years as more people want to keep fit while experiencing a slower and authentic form of travel.
Many cities also offer bike rentals allowing for an economical, clean, and easy way to move about urban areas.
Inquire if your hotel or resort provides bikes for guests and take the opportunity to pedal your way through the local community.
Always be sure to abide by local traffic and safety laws, and respect the dress codes of the places you ride in.
The ultimate in fuel efficiency, with the added bonus of a health benefit! Many destinations are highly accessible on foot. Where possible, try to take the extra time to sightsee, visit a restaurant, go to your hotel, or shop, using the oldest form of transport.
