Each G-20 meeting has created its own Web site of documents, with varying degrees of comprehensiveness. No central repository exists of G-20 documentation, but some recent initiatives might help.
Bloomberg Law has started a G-20 Declarations library under the “Global Law” tab. It includes declarations from the G-20 summits since 2008. http://www.bloomberglaw.com

Climate ChangeS provides researchers with a timely and accurate update of new research papers on the Economics of Climate Change. On a weekly basis, links to the most recent and interesting working papers are aggregated from a variety of sources for easy and convenient reference. The focus is on research at the frontier, with most contributions appearing just a few days after having been released. For this reason, journal articles are not tracked.
Global Warming Policy Foundation is a UK based climate change site (more Bjorn Lomborg than Al Gore)
From the Web Site’s Information Page
The Global Warming Policy Foundation (GWPF) is an all-party and non-party think tank and a registered educational charity
Our main purpose is to bring reason, integrity and balance to a debate that has become seriously unbalanced, irrationally alarmist, and all too often depressingly intolerant.
The GWPF’s primary purpose is to help restore balance and trust in the climate debate that is frequently distorted by prejudice and exaggeration
Our main focus is to analyse global warming policies and its economic and other implications. Our aim is to provide the most robust and reliable economic analysis and advice.
We intend to develop alternative policy options and to foster a proper debate (which at present scarcely exists) on the likely cost and consequences of current policies.
We are funded entirely by voluntary donations from a number of private individuals and charitable trusts. In order to make clear its complete independence, it does not accept gifts from either energy companies or anyone with a significant interest in an energy company.
