Cumulative manmade greenhouse gas emissions

Over 63% of cumulative manmade greenhouse gas emissions have been generated by just ninety companies. Fifty of these companies are Investor owned, 31 are State owned, and 9 are Nation state owned.

Six Canadian companies are in the top ninety: Encana, Suncor, Canadian Natural Resources, Talisman, Husky Energy and Nexen.

Cumulative ManMade Emissions



Focus on Wellhead rather than Tailpipe emissions

Instead of focusing on the emissions generated at the "tailpipe", perhaps we should work to limit the sources of fossil fuels. Proposals for a fee and dividend carbon pricing mechanism are that a fee be applied at the "wellhead" - where the fossil fuel is extracted or imported. Two different mechanisms can achieve this:

  • Fee and Dividend - would apply a fee at wellhead and return this fee to all households. (Citizens Climate Lobby lobbies for this.)
  • Cap and trade also applies to the wellhead. In many ways, cap and trade is more effective since it caps the emissions the source rather than relying on a fee to encourage the reduction in emissions. A hybrid approach could be effective.
