Emma Harvey, The Head of Sustainability for Virgin Atlantic, has authored an article published by 2Degrees, indicating that the company is pushing for biofuels to replace traditional fossil fuels in aircraft. She quotes a target of 60% reduction in aviation carbon emissions on 19% of the world's aircraft. So that's about 20% reduction in emissions from the world's aircraft, assuming no increase in air travel (which is unlikely). That's good news overall, but I wonder if it goes far enough. Emissions from air travel, per passenger- or freight-kilo-mile, and in aggregate, are still an issue compared with other forms of transport. Click the link here to my blog post "Impact of food transport by air", where I compare freight miles travelled on various modes of transport. There is a big question remaining over what level of total air travel is sustainable.

I like what Repowering London had to say at this conference at the Birmingham NEC today. They are doing great work in implementing community renewable energy. The picture is of one of their slides which highlights the main outcomes from their . I think in the bottom-right of the slide there is a small typo - "50 kWh" should be "50 kWp" (ie the abbreviation should be the one for "kilowatt peak" not "kilowatt hours"). |
