LINKS

This section provides links to other independent work and references to interesting literature on GHG-removal.

Please note that our linking to these initiatives and organisations does not imply in any way that there is a formal association between us, not even that they support what we are doing, we nonetheless wanted to highlight and link to their fantastic efforts.

The Carbon Cycle:

  • The Global Carbon Project’s scientific goal is to develop a complete picture of the global carbon cycle [click here]

Cutting emissions in the first place:

As we keep saying, ways of taking greenhouse gases out of the air should never distract from the need to cut greenhouse gas emissions in the first place right now:

  • Help get emissions reduction activities to a gigatonne scale with the Carbon War Room, who’ve recently teamed up with the Rocky Mountain Institute  [click here]
  • Learn about the science of climate change, the international action being taken and the economic rationale behind a price on carbon through the Climate Commission [click here]
  • Take the Climate Reality Pledge [click here]
  • Organise a screening of Peter Byck’s film: Carbon Nation [click here]
  • Read the IPCC AR5 reports, especially the synthesis report. Right now. Do it. [click here]
  • …and use this ‘Trillonth Tonne’ clock by the University of Oxford to remind people that yes, the clock is ticking  [click here]

…and while you’re at it:

  • Join the B Team in helping businesses realise their potential to deliver strong external social, economic and environmental benefits [click here]
  • Explore Virgin Unite’s community to use business as a force for good [click here]
  • Help the Ocean Elders catalyse the conservation of the ocean and it’s wildlife [click here]
