Your main concern may be with the growth of air travel, and the environmental damage it does. This is not only climate change, but also destruction of communities, damage to habitats near airports, noise and local air pollution

Why is air travel uniquely damaging?

Taking into account the x2 multiplier, a return trip for one person by air to New York produces about the same amount of climate changing effect as an average UK car (about 35 mpg) in a whole year's motoring.   A return flight to Rome would produce about as much climate changing effect as all of one person's gas and electricity use for a year.   The longer your flight, the more CO2 emitted into the atmosphere (though the taking off is the worse component of the flight - for emissions).

This demonstrates how easy it is - when flying - to produce a huge % of a person's CO2 output, without ever really being aware of it.  Driving 6,000 miles in a car would take a very long time, and be extremely tiring and boring.  You can produce the same emissions of CO2 in a couple of hours on a plane, comfortably sipping a glass of wine and watching a movie.

The amount of CO2 that each person's activities put into the atmosphere (heating, lighting, car use, travel, use of appliances, things we buy, services we use) is called our carbon footprint.

The UK Government has set itself a target of a 60% reduction in CO2 emissions for the country, by 2050.  With air travel growing at its current rate, (perhaps 7 - 8% per year) we are on target for aviation to contribute a higher and  higher proportion of the UK's total CO2 emissions.  Aviation emissions will continue to grow, under current government policies, while all other sectors of the economy have to cut theirs.   This is nonsense.   The UK's aviation policy, as set out in the 2003 Aviation White Paper (and confirmed at the end of December 2006), is utterly at odds with the Government's policies on climate change.  If ever there was a case of a deplorable absence of "joined up thinking"  - this is one.
