While additional capacity has been built since 1998, the inherent slow growth of the animals, and subsequent long production cycles ensure that the current production volumes remain small (180 tonnes in 2000; Table 5), although there are indications that some 500 tonnes will have been produced by the end of 2001.
The £635m the GIB had invested by the end of March had by that date reduced a relatively small 22,498 tonnes of carbon dioxide equivalent.
The result is that the all-told reduction in emissions in 2035 is remarkably small: 160m tonnes of carbon dioxide, rather less than the Netherlands emits today.That more energy is being used than ever before is a welcome sign of economic growth after a sharp downturn.
The primary reason for this is the absence of cost effective, small-scale (∼10,000 tonnes per annum), environmentally sound pulping technology.
There are ships that carry refined oil products, and perhaps some other cargoes like molasses, which tend to be in the smaller 12000 tonnes to 50000 tonnes deadweight range.
In 2011 Nasa calculated the chance of a smaller 6.5-tonne object striking someone was about one in 3,200.
Under chemicals legislation introduced in 2006, manufacturers have since November 2010 had to file information about compounds they put on the market, although compounds produced or imported in small volumes (1 100 tonnes) per year were exempt until last May, and production at even lower levels doesn't need to be registered at all.
It is noted, however, that last year's cereal imports across the monitored border posts were extremely small – under 2 000 tonnes.
Bluefin tuna fishing has never seen so much surveillance as this year.The quota for 2010 is 40% smaller, at 13,500 tonnes, than last year.
Many of the ships involved in the worst crimes, like the Shin Jyi Chyuu 33, are smaller than 300 tonnes and thus exempt from the system entirely.
