A história do CO2 até mete nojo, daqui a bocado andamos todos cancerosos mas não interessa porque o CO2 é pouco [:vm)]
Só por causa das cócegas eu quando for grande vou andar aí a emitir umas 500g/Km.

Daqui a pouco ficamos proibidos de respirar, praticar exercício físico ou ir para a cama com a mulher para não emitirmos dióxido de carbono...

Como é que têm o desplante de pensar pela própria cabeça?O CO2 tem sido a mina de ouro a nível mundial para muita gente, mesmo com a comunidade científica à perna a dizer que é uma fraude o lobby é demasiado grande neste momento.
Eles não querem saber da poluição, sabem sim que é a desculpa do século para sacar impostos. Monstruosidades de impostos e a consciência ECO de cada um de nós não se revolta nem se sente vigarizada, porque afinal convenceram-nos que é por causa da natureza ( e ela própria produz quase todo o CO2). Curioso não é? Asa próprias vacas produzem mais CO2 que os carros.

Por exemplos os NoX (óxidos de azoto) são brutalmente mais perigosos que o CO2. Provocam as chuvas ácidas que (curiosamente) disparam os valores de CO2, matam as plantações, contaminam as águas e tudo em que tocam. Toda a gente está com medo da radiação na água causada pela central nuclear mas esquecem-se que temos cá chuvas ácidas em abundância, principalmente em países onde abundam veículos diesel. O mesmo para as partículas tóxicas. Isto são factos detalhados com estudos médicos de cancros, asma, bronquite e outros danos à saúde mais que comprovados. Alguém se importa? Pois, mexe com interesse instalados e ia entrar em rota de colisão com os veículos que declaram menor consumo, ou seja, que emitem menos CO2...

Isto é um jogo de interesses e não querem saber da nossa saúde nem da do planeta. Agora que os estados têm engordado à grande com a consciência do CO2, lá isso têm! E prepararem-se que querem taxa-lo ao km, quando mais andam de carro mais taxa de CO2 pagam []
Cada um vê o que quer ver e sobre o CO2 bem podem enfiar a teoria num sítio que eu cá sei, daqui a pouco ficamos proibidos de respirar, praticar exercício físico ou ir para a cama com a mulher para não emitirmos dióxido de carbono...
espero bem que não
e que não alterem o ciclo de medição.
Economic with the truth

I’m just back from a very interesting trip to the Hyundai Kia European Research and Development Centre. Based in Opel’s home town of Rüsselsheim, it’s home to a substantial powertrain development centre, as well as a big design studio.
We were shown around some of the centre’s test beds by Dr Joachim Hahn, including the lab where the NEDC (New European Driving Cycle) fuel economy tests are replicated. Like most drivers, I’ve long been suspicious of the NEDC figures, which don’t seem to relate to the real world.
So I asked Dr Hahn about the NEDC and the conditions in which the test are carried out. Incredibly, cars are tested in ambient temperatures of 25degC (77degF) after being ‘pre-conditioned’, or warmed up. Of course, warm summer days are rather better for fuel consumption that freezing conditions, when oil is thicker and internal friction greater. Hahn said tests at -10degC showed real-world consumption was ‘much worse’ than in normal conditions.
Dr Hahn also revealed that the car industry was currently in negotiations with the European authorities about changing the parameters for the NEDC, by ‘starting the test at a cooler temperature and making it more dynamic’. Which, translated, means making the tests just a little more like real-world conditions.
The downside to this outbreak of reality is that the stated fuel economy of virtually every car on sale will get worse and the all-important Co2 figures will rise. Changing the NEDC test then raises the problem of how car makers will then hit the fleet average Co2 targets that the EU is demanding.
Remember, that by 2020, a car maker’s average Co2 output, across its entire range, has to be just 95g/km. If the NEDC test is changed, car makers may not be able to hit the agreed target. So either the test changes, or the EU’s targets do.
Still, the appliance of science by the car industry, in the pursuit of fuel economy remains impressive. Even accounting for the unrealistic NEDC test, the 85g/km-rated Kia Rio 1.1-litre diesel is an amazing achievement. With the diesel motor meeting EU5 pollution regulations, the case for conventional, costly, hybrids is further undermined.
Interestingly, Hahn suggested that a battery electric vehicle, when charged up in continental Europe, should be awarded a Co2 rating of around 75g/km. Of course the EV’s 75g/km is ‘real world’ because driving conditions do not affect the Co2 emissions of the power station supplying the juice.
So, although this Kia’s 85g/km won’t quite be repeated in the real world, it shows just how much life there is left in the internal combustion engine.
Ferrari is making the most significant progress of Europe’s high-end supercar makers in reducing its fleet CO2 emissions, Autocar has discovered.
Ferrari recorded an average of 326g/km in 2010, down 46g/km, according to figures from JATO Dynamics in its yearly report into the European industry’s progress towards a 130g/km fleet average.
Ferrari’s cut is equal to 12 per cent, about half the total reduction that volume car makers are expected to manage by 2015. “Manufacturers have made significant improvements in 2010, and it will be fascinating to see how they respond as emerging high technology goes more mainstream,” says JATO.
Figures are calculated around the mix of sales of individual cars, so Ferrari is benefiting from the larger proportion of Californias in its sales. Averaging 301g/km, the California contributed 46 per cent to Ferrari’s sales last year, versus 33 per cent in 2009.
Among the competition, Aston Martin managed a 0.6 per cent reduction, Bentley 1.9 per cent and Lamborghini 1.5 per cent. Aston’s fleet average dropped to 357g/km, Bentley’s to 397g/km and Lambo’s to 372g/km.
For Bentley, the new Mulsanne was a major contributor; its CO2 output of 393g/km is a big improvement over the old Arnage’s 465g/km.
Only Lotus managed more at 3.2 per cent, aided by greater sales of the Elise and a significant reduction in its tailpipe carbon from 204g/km to 198g/km.
These figures show the importance of a sports car maker being owned by a major manufacturer, whose fuel-efficient superminis can offset its supercars.
That applies to Fiat-owned Ferrari, VW-owned Bentley and Lamborghini and Proton-owned Lotus, but not Aston Martin. This is why Aston is launching the Cygnet city car, whose 99g/km average will help balance out its model range.
The EU will fine car makers for missing targets, starting at five euro per car for the first gram/kilometre and rising to 95 euro for the fourth. Fines could run into millions.
