Kyoto Protocol: first lap in long race against time
7 May 2008
In a keynote address in Sydney today to the Kyoto Policy in Practice conference, Dr Jones says the Kyoto Protocol represents the starting line for a critical assessment of climate change from which the finishing line cannot be seen.
“The good news is that we can make a start on cutting greenhouse emissions now, and the more we cut emissions in the future, the more we will value these first important steps,” he says. “The best way to ensure that costs and benefits balance each other is to ensure that cuts to greenhouse gas emissions are also economical, equitable and environmentally beneficial.”
Dr Jones says that since the emissions scenarios used by the Intergovernmental Panel on Climate Change (IPCC) were produced in 2000, the world has moved to a new economic growth path, driven by developing countries and commodity providers such as Australia. This increased the risks of climate change and its impacts beyond those assessed by the IPCC in its latest report.
He said, according to research conducted jointly by CSIRO and Victoria University, Melbourne, the major benefits of the Kyoto Protocol will not be the reductions in climate change themselves but the lessons we need to learn in order to mitigate the increasing risks.
“We need better methods for updating climate risks and assessing the benefits of avoided damages by investing in new technology and other measures,” Dr Jones said. “Rapidly emerging climate risks fuelled by faster than projected emissions growth make this task all the more urgent.”
He said critics of the Kyoto Protocol, have suggested that the small cuts achieved would not provide sufficient benefits, but work done by he and the US climate change economist, Professor Gary Yohe – to be published in the Integrated Assessment Journal – indicates that the opposite is true.
“Because these cuts reduce the worst risks from a ‘do-nothing’ case, the returns far outweigh the costs. However, it has been difficult to compare those costs and benefits because they are economic, social and environmental,” Dr Jones said.
“Perhaps the major benefits of the Kyoto Protocol may not be the reductions in climate change themselves but the lessons we need to learn in order to mitigate the rapidly increasing risks.
“In the race to reduce climate risks, the Kyoto Protocol is the first lap. If we want to minimise those risks, we will have to quickly learn how to drive very fast,” he said.
The conference was also shown new ways of looking at the benefits that are derived from investment in greenhouse gas reductions. Work done as part of the CSIRO’s Energy Futures Forum, shows that it is very likely cuts to greenhouse gases by 2050 will pay for themselves by 2100 in pure economic terms.
