Great news that HP is #1. But the bigger story for me around the Newsweek rankings is that:

4 of the top 5

5 of the top 10 and

10 of the top 20 companies in the rankings are from one sector: technology.

What story does this tell? A number:

1) Competitive pressures around the environment are proving a real driver to improving sustainability performance in the tech sector.

2) The regulation, mostly stemming from the EU, to control tech companies' environmental impact has spread through out the world and can point to some success stories.

3) That attempts to further clamp down on this sector eg Commissioner Reding's desire to have ICT companies hit the EU's 20:20 early, by 2015, are in fact misplaced.

4) That regulators, instead of looking to constrain technology companies further, should look at other targets. Technology accounts for just 2% of global carbon emissions. But technology can help attack the other 98% through video-conferencing, smart grids, smart buildings and smarter transport. We need smarter policy to help!

In other words, the debate must shift. Technology companies are leading the way (with HP leading the tech companies). We should now look to how this innovation-led industry can help solve the problems of climate change.
