Change in Climate

I’m doing a science experiment of different octane levels in gas and how much greenhouse gases each put out. What device can I get to measure this. If none, than something that measures just CO2?

Doing a research project on different energies.

“If Diesel fuel was fully implemented, estimate the reductions in greenhouse gas emissions nationwide.”

Having only just discovered this interesting new feature, and having read some of the answers given about climate change I thought I’d ask my own. Why are some people so against reducing greenhouse gas emissions? Surely it makes complete sense to use as little energy as possible and to generate energy by means which are renewable and do not rely on fuel of which there is only a finite amount? I mean, surely that makes perfect economic sense? Whether or not you dispute the science of climate change (and from my experience that vast majority of genuine scientists do not) I can see no logical argument against trying to reduce greenhouse gas emissions.
