Carbon tax becomes a peculiar piece of legislation when viewed from Pirate Party&#x27;s perspective (not necessarily that I agree with it, no <i>ad hominem</i> please). According to Rick Falkvinge [1] legislation must:<p><pre><code>  * Be targeted at a problem
  * Solve the problem
  * Not create other problems in best case, worse problems in worst case
  * Be evidence based

Carbon emission is considered a problem because it contributes to climate change. For carbon tax to be considered targeting a problem we must accept that climate change is a problem.<p>Does it solve a problem? At least not directly. Taxes on tobacco and alcohol do not eliminate consumption, prohibition in US created a Mafia, jail-time for drug possession does not eliminate consumption, we have hard evidence confirming that.<p>Such tax hinders accessibility, though. Since at least transportation is fossil fuel dependant, more or less everything (commodities including: food, public transportation) will get more expensive, thus less accessible.<p>Do we have hard evidence (numbers, not general economic speculation) that x level carbon tax will lower carbon emissions by y?<p>[1]: <a href="http:&#x2F;&#x2F;falkvinge.net&#x2F;pirate-wheel&#x2F;principles&#x2F;quality-legislation&#x2F;" rel="nofollow">http:&#x2F;&#x2F;falkvinge.net&#x2F;pirate-wheel&#x2F;principles&#x2F;quality-legisla...</a>
