WordWeb 5.0 Free version licence
Please note a new version is now available - see the download page
WordWeb 5.0 may be freely used only by people who meet the conditions below.
Global greenhouse gas emissions are currently around 5 tonnes per person per year, and need to be reduced by about 80% have a good chance of avoiding catastrophic warming. Most computer users are responsible for far more emissions than is sustainable. For example one medium distance return flight can be equivalent to over 1 tonne of emissions1: more than an average person should be emitting in an entire year. A typical SUV causes about twice as much warming per mile as a typical normal European car: 10,000 miles of travel in an SUV is responsible for about 5 tonnes of emissions. Offsetting emissions is no substitute for direct cuts.
You may use the program free of charge indefinitely only if
- You take at most 4 flights (2 return flights) in any 12 month period
- AND you do not own or regularly drive an SUV (sports utility vehicle).
If you do not qualify you must uninstall the program after the 30-day trial period or purchase WordWeb Pro. The licence is designed to provide a small incentive for people with massively unsustainable emissions to cut down.
Whenever a user no longer meets the above requirements, and they have installed
the product for more than 30 days, they must uninstall the product or purchase WordWeb Pro; otherwise it is software theft.
There are two exceptions to the above: not-for-profit educational establishments may install
WordWeb for the use of their students (regardless of whether their students meet the
"sustainable user" requirement), and the registered disabled who require an SUV for transport may use the program freely if they take at most four flights per year.
Please note that even if you meet the above requirements you are probably still unsustainable: turn down the heating (or reduce the amount of air conditioning), use energy efficient lighting, insulate your house and travel by public transport whenever possible.
See additional licence discussion.
1 Flights are be particularly bad because of additional non-carbon emissions and cloud formation at high altitude: the short-term warming effect is estimated to be many times worse than the same CO2 emission at ground level, perhaps a factor of two worse on a twenty-year timescale, but it could be much worse.
