Google looks set to play a part in a called-for "new environmental world order" by satellite-monitoring the rates of deforestation of tropical rainforests and pinpointing illegal logging and land misuse, Google's Northern and Central Europe head Philipp Schindler has revealed.
Schindler made the announcement in London on November 19 at a meeting at St James's Palace hosted by the Prince's Rainforests Project about a new climate change reduction mechanism, REDD (Reduced Emissions from Deforestation and Degradation).
An inter-governmental report produced this month by an Informal Working Group (IWG) for Interim Funding of REDD has outlined an initiative to save the CO2 equivalent of the annual emissions of the US over five years by rewarding developing countries for reducing deforestation, with payments on a performance basis.
The felling of forests causes almost a sixth of global carbon emissions. By ensuring that forests are "worth more alive than dead", the money is aimed at encouraging rainforest nations to see the carbon stored in their intact forests as a financial asset and to pursue sustainable forms of economic development.
"To do this, what is needed is a system to monitor changes in rainforests across the world," said Schindler. "Our engineers are now designing a global forest open platform for this. We have access to a large database of historic and current satellite images and while this is something that is going to require huge computing power, that is something Google is very good at."
The REDD initiative has involved negotiations with more than 35 countries and the meeting was attended by heads of state, President Jagdeo of Guyana and President Bongo of Gabon, senior ministers from 18 countries, including the UK Secretary of State for Energy and Climate Change Ed Miliband, arctic explorer Pen Hadow, scores of industry leaders and the world's leading environmental NGOs.
Prince Charles was heartened by the findings of the report on REDD. "It does seem that we have arrived at a consensus on how emergency funding might be deployed in the near future," he said.
An example of how the scheme could work is already underway thanks to Norway, which has pledged $250m to Guyana by 2015 to continue to prevent deforestation and up to $1b to Brazil.
Per Frederik Pharo of Norway's Environment Ministry said that REDD was complicated because the world "was basically asking developing countries not to do what they do naturally – use their forests to develop" but the new incentive structure worked for both Guyana and Brazil and for the world.
He urged other countries to back REDD: "The difference between starting now and not could make the difference between reaching or not reaching the climate change tipping point," he said. REDD, he added, would give the world the opportunity to make a comprehensive land-use programme and ensure global food security: "By getting control of global deforestation, we can address these issues too."
The cost of launching REDD is estimated at 15b and 25b over the next five years and the money will initially be sought from governments. The US pledged $275m at the meeting towards REDD but where the remainder will come from is not certain. It will be discussed at COP15, the crunch UN climate change talks in Copenhagen in December.
Many speakers at the meeting were frustrated at the pace of progress. President Bongo of Gabon, a Central African country that is more than 80% forested with low deforestation rates, said he was in full support of REDD but that "external pressures, such as agriculture and bio-fuel development" were mounting. "With the remarkable exception of Norway's commitment to kickstarting significant action on the ground... the developed countries have not respected their Bali action plan commitments and are spectators, waiting for the rainforest countries to take the plunge," he said. The world's atmosphere and forests had to be seen as a "common good", he added, and to resolve the world's ecological problems, part of the wealth of developed nations would also have to be a "common good": "This calls for a common vision... a new environmental world order," he said.
It was "time for the world to step up", said President Jagdeo of Guyana: "25b is about the bonus pool of Goldman Sachs. We have to walk away from Copenhagen with interim funding for REDD. We want a specific commitment."
The urgency was echoed by speaker after speaker. Ken Lay, treasurer of the World Bank, said the investment was now "a challenge of the first order"; John Sauven, executive director of Greenpeace UK said it was "time to put the money on the table"; Graham Wynne, chief executive of the RSPB, said: "Can we just get on and do the deal?" and Ed Miliband vowed that Copenhagen "would not be just another declaration of hot air."
Prince Charles closed the meeting saying: "This is one of those 'what would have happened if?' moments. The path we choose is critical. Let's not make this an 'if only' moment."
Chatham House is assessing the scale and effectiveness of the response to illegal logging and the related trade around the world. Full details of this work, including analysis and data, will be available online soon.
