Boeing — Phil Angel philangel72 March 11, While some international airlines and governments grounded the MAX 8 planes, a day after the crash US airlines, the Federal Aviation Administration and Boeing had not. Ethiopian Airlines and Cayman Airways both grounded the planes of that model they were operating.
China and Indonesia grounded MAX 8 planes in operation in both countries. The announcement acknowledged that investigators had not yet determined the cause of the Ethiopian crash or whether it was the same cause as the earlier crash, last October. The FAA says it has a team on site in Ethiopia "collecting data. Boeing released a statement Monday describing the software upgrade, which said in part:.

Boeing has been working closely with the Federal Aviation Administration FAA on development, planning and certification of the software enhancement, and it will be deployed across the MAX fleet in the coming weeks. The update also incorporates feedback received from our customers. It is important to note that the FAA is not mandating any further action at this time. Passengers can look up the model of plane they are flying on for any given flight. It's often listed on boarding passes or tickets, or passengers can call and ask the airline.

If they see they would be flying on a MAX 8 and they choose not to take that flight because they feel unsafe, American Airlines and Southwest Airlines both said their standard flight change policies would apply. For American, each passenger is charged an additional fee if a change is made to the flight. For Southwest, passengers can change their flights with no charge. Passengers pay only the difference in fare when they change flights on Southwest.

Legally, passengers do not have much recourse when it comes to changing flights free of charge or getting full refunds. FAA regulations say airlines are able to change planes "jet for jet," meaning that if it is the same class of plane and they change the specific model at the last minute, they are not required to provide any kind of refund, according to aviation attorney Mary Schiavo, a CNN transportation analyst and former inspector general at the US Department of Transportation.
The extra impact of nitrogen oxides, ozone, water vapor, soot and sulfurs released by planes is called the Radiative Forcing Index. The IFEU model assumes that this additional global warming effect comes into play when flying at a height of 9 kilometers or higher. High-speed trains run on electricity, so the IFEU estimates their greenhouse gas output based on the emissions involved in generating power.
These vary by country : Poland, for example, generated 89 percent of its electricity through coal, gas or oil in , whereas in Germany the figure was 58 percent. It's not hard to understand the time and money involved in a trip.
But how are we supposed to decide whether kilograms pounds of carbon dioxide is a reasonable price to pay for our weekend minibreak? Enter the social cost of carbon. Economists have been working on this idea for years. The theory is simple: If we can estimate the cost of climate change on society — and we know that greenhouse gases lead to climate change — we can put a price on carbon emissions.
The main purpose is to help governments decide whether spending money on carbon-reduction measures is worth it. But we can also apply the social cost of carbon to our journeys.

There is no academic consensus as to how much the social cost of carbon should be. But some researchers say those figures fail to capture the potential consequences of catastrophic climate change and the number should be at least 10 times higher. This represents the high end of estimates of the social cost of carbon. Adding the social cost of carbon to our train and plane ticket prices means things start to look quite different:.
Planes are cheaper on three of the routes. If you add the social cost of carbon, the actual figure is much higher — especially for planes, which become the way-more-expensive option to travel. We've presented all the data in one diagram showing the ticket price, journey time and carbon emissions for each route.
When factoring in all the above-mentioned aspects, the chart shows that the overall cost of a train trip is now lower than that of a flight for nearly all of the journeys. With a more realistic assessment of travel times and the social cost of carbon factored in, the cost of train travel generally runs lower than that of flights, with the blue triangle appearing almost fully within a red triangle. Of course, this is just an experiment, and there's no academic consensus as to how much the social cost of carbon is, or whether it is the right approach to environmentally friendly decision-making.
But adding a levy to ticket prices based on emissions — a carbon tax — could be an effective way of decreasing the contribution of consumer air travel to climate change and encourage people to find more environmentally friendly ways of making their journeys. David Hodgkinson, an associate professor of law at the University of Western Australia, argues that a carbon tax is needed, especially given the complexity of other cross-border strategies for reducing emissions.
Most people, and even the airline industry, would accept that there needs to be some form of price on aviation emissions. Read more: Buy your right to pollute. Hodgkinson is critical of existing initiatives to tackle aviation emissions, including a carbon offsetting model drawn up by the International Civil Aviation Organization. Emissions will likely increase year on year," he said. Roger Tyers, a behavioral scientist who has researched carbon offsetting approaches at the University of Southampton, believes that increased costs alone may not be enough to reduce the demand for air travel.

He said more investment in high-speed rail would help close the gap in journey time, and that people need cultural signals to encourage them to change their behavior. Tyers said, however, that European leaders have been unwilling to confront the proliferation of consumer aviation.
Many aviation companies offer an option to offset carbon emissions. But where does that money go, and how effective is this contribution?
Though air travel is more popular than ever, the vast majority of people in the world have never been on a plane. As that dynamic slowly changes, the environment stands to suffer. Is flying less the only solution? Germany's long-awaited high-speed rail link between Berlin and Munich has finally been inaugurated. People are now aware of climate change. But almost no one wants to do without a holiday flight or cruise. The UN's scientific body on climate change highlights in a new report the strong connection between land use and climate change.
