A new joint statement was released today:
The problem is not yet insoluble, but becomes more difficult with each passing day. A goal of confining global warming to an average of 2 centigrade degrees above pre-industrial levels would be very challenging, and even this amount of warming would be likely to have some severe impacts. . . .
We call on world leaders, especially those meeting at the G8 Summit in June 2007, to:
• Set standards and promote economic instruments for efficiency, and commit to promoting energy efficiency for buildings, devices, motors, transportation systems
and in the energy sector itself.
• Promote understanding of climate and energy issues and encourage necessary behavioural changes within our societies.
• Define and implement measures to reduce global deforestation.
• Strengthen economic and technological exchange with developing countries, in order to leapfrog to cleaner and more efficient modern technologies.
• Invest strongly in science and technology related to energy efficiency, zero-carbon energy resources and carbon-removing technologies.
