By Hans Nilsson / Published on Wed, 2007-07-11 07:00

A few of the really big companies speak with a different voice from that of the others and, for that matter, different from that which they used themselves a few years ago. The CEO of Royal Dutch Shell recalls in three "hard facts":

Voluntary Carbon Offsets - still a long way to go

By Hans De Keulenaer / Published on Sat, 2007-04-21 12:33

Stories mushroom of individuals and organisations offsetting their carbon emissions by purchasing credits. With increasing demand for carbon offsets, several dozens of companies now offer such credits [1]. Prices vary, but typically you can go carbon-free for a price of 5 to 10 $/tonne CO2. A typical European with a carbon footprint of 10 tonne could go carbon-neutral for less than 100$.

Are you an Atoner, a Goddess or a Boomer?

By Hans Nilsson / Published on Fri, 2007-04-20 07:00

Or would you rather be something else? The British Energy Saving Trust has made a green barometer that basically shows we think better of ourselves than we actually live up to, but also that there is hope for improvements.

The rest of us, not being subjects of the Queen, may nevertheless take some impression of this profiling. It clearly illustrates that sustainable energy is not an issue of technology improvements only but also a change in life-style. And one of the habits hard to give up is air-travelling.

Not a "Global Warming" rant

By Hans De Keulenaer / Published on Mon, 2007-03-26 22:24


This is not going to be rant on the global warming movement, nor a rant on its believers and non-believers. But by now, you probably have heard about Channel 4's 'The Global Warming Swindle':

A good laugh helps the medicine go down

By Hans Nilsson / Published on Thu, 2007-03-01 10:04

Monty Python are British, aren't they? And it is in U.K. that the campaign for Flying to the end of the world was invented. Good laughs with a deep meaning. The people behind the campaigns have a solid business background that they have put into the service of climate care.

It is important to note that it is not travelling itself that is in the line of fire but the travel where the purpose is obscure or non-existing.

The EU Action Plan heats the normally cool Finns

By Hans Nilsson / Published on Fri, 2006-09-29 11:11

The power struggle in Brussels over the missing efficiency action plan is taken to new heights! The Finnish presidency threatens to cancel the next council meeting with energy ministers if the action plan is not put on the table. A thing that has never happened before in the EU history!

Climate change - from tidal wave to tsunami?

By Hans Nilsson / Published on Mon, 2006-09-04 05:18

One of the explanations, that political actions to prevent climate change are so slow, is that the observed physical changes also are slow. We gradually get used to the changes just in the same way as eye-sight is reduced and we only discover one day that maybe we should have seen a doctor earlier to get medical help or at least glasses. In the film "An inconvenient truth" the phenomenon is illustrated with a frog that sits in water that is gradually warmer and does not observe that it will soon be boiled.

Action, not talk

By Hans Nilsson / Published on Thu, 2006-02-02 06:15

Members of the European Parliament and some national Parliaments have taken an initiative for action on energy efficiency and forming an “Energy Efficiency Watch”. They show not only that energy efficiency is the biggest energy source in Europe but that Europe stands the risk of lagging behind in development. Even more important, they give a long list with concrete examples of what they as legislators can do This is certainly contrary to what we normally think and say about politicians! They act and they act across the party lines. Energy efficiency is a citizens’ and not a political partisan issue. Every day that the efficiency resource is left without consideration is a day when valuable resources are wasted.
