At the peak of the claim and counter-claim thrown around over Amazongate Simon Lewis a forest researcher at the University of Leeds emerged briefly at its centre. Lewis’ defense of the actions of the IPCC helped the organization avoid confronting its use of advocacy and environmental pressure group material from the WWF. A little-examined fact at the time was that Lewis’ parent department was involved along with contributions from the University of East Anglia (UEA), the Royal Society, the David and Lucille Packard Foundation and other non-governmental organizations in a UN REDD+ pilot project in Tanzania. Called ‘Valuing the Arc’, it was designed to work out putting a ‘price on carbon’ to provide ”input to the policy process, … including PES mechanisms”. ‘PES’, is payment for ecosystem services, i.e., REDD. The most prominent NGO at the the centre of the project? WWF-Tanzania.
