To help make the case for tackling climate change by:
• Showing detrimental impacts
• Illustrating aspirational low emission pathways.
Ahead of the 2015 negotiations, we want to use the Global Calculator
to make a compelling case on the need to take action
Target audience for tool are business leaders, NGOs
and Governments.
