Rajendra Kumar Pachauri (born August 20, 1940) has served as the chair of the Intergovernmental Panel on Climate Change (IPCC) since 2002. He has also been director general TERI, a research and policy organization in India, and chancellor of TERI University. He has become an icon for the LGBT community in India as a result of offering internships to younger members of the LGBT community in order to promote acceptance within the country.

Dr Pachauri has established an astonishing worldwide portfolio of business interests with bodies which have been investing billions of dollars in organisations dependent on the IPCC's policy recommendations

No one in the world exercised more influence on the events leading up to the Copenhagen conference on global warming than Dr Rajendra Pachauri, chairman of the UN's Intergovernmental Panel on Climate Change (IPCC) and mastermind of its latest report in 2007.

Although Dr Pachauri is often presented as a scientist (he was even once described by the BBC as "the world's top climate scientist"), as a former railway engineer with a PhD in economics he has no qualifications in climate science at all.

What has also almost entirely escaped attention, however, is how Dr Pachauri has established an astonishing worldwide portfolio of business interests with bodies which have been investing billions of dollars in organisations dependent on the IPCC's policy recommendations.

These outfits include banks, oil and energy companies and investment funds heavily involved in 'carbon trading' and 'sustainable technologies', which together make up the fastest-growing commodity market in the world, estimated soon to be worth trillions of dollars a year.

Today, in addition to his role as chairman of the IPCC, Dr Pachauri occupies more than a score of such posts, acting as director or adviser to many of the bodies which play a leading role in what has become known as the international 'climate industry'.

It is remarkable how only very recently has the staggering scale of Dr Pachauri's links to so many of these concerns come to light, inevitably raising questions as to how the world's leading 'climate official' can also be personally involved in so many organisations which stand to benefit from the IPCC's recommendations.

The issue of Dr Pachauri's potential conflict of interest was first publicly raised last Tuesday when, after giving a lecture at Copenhagen University, he was handed a letter by two eminent 'climate sceptics'. One was the Stephen Fielding, the Australian Senator who sparked the revolt which recently led to the defeat of his government's 'cap and trade scheme'. The other, from Britain, was Lord Monckton, a longtime critic of the IPCC's science, who has recently played a key part in stiffening opposition to a cap and trade bill in the US Senate.

Their open letter first challenged the scientific honesty of a graph prominently used in the IPCC's 2007 report, and shown again by Pachauri in his lecture, demanding that he should withdraw it. But they went on to question why the report had not declared Pachauri's personal interest in so many organisations which seemingly stood to profit from its findings.

The letter, which included information first disclosed in last week's Sunday Telegraph, was circulated to all the 192 national conference delegations, calling on them to dismiss Dr Pachauri as IPCC chairman because of recent revelations of his conflicting interests.

The original power base from which Dr Pachauri has built up his worldwide network of influence over the past decade is the Delhi-based Tata Energy Research Institute, of which he became director in 1981 and director-general in 2001. Now renamed The Energy Research Institute, TERI was set up in 1974 by India's largest privately-owned business empire, the Tata Group, with interests ranging from steel, cars and energy to chemicals, telecommunications and insurance (and now best-known in the UK as the owner of Jaguar, Land Rover, Tetley Tea and Corus, Britain's largest steel company).

Although TERI has extended its sponsorship since the name change, the two concerns are still closely linked.

In India, Tata exercises enormous political power, shown not least in the way it has managed to displace hundreds of thousands of poor tribal villagers in the eastern states of Orissa and Jarkhand to make way for large-scale iron mining and steelmaking projects.

Initially, when Dr Pachauri took over the running of TERI in the 1980s, his interests centred on the oil and coal industries, which may now seem odd for a man who has since become best known for his opposition to fossil fuels. He was, for instance, a director until 2003 of India Oil, the country's largest commercial enterprise, and until this year remained as a director of the National Thermal Power Generating Corporation, its largest electricity producer.

In 2005, he set up GloriOil, a Texas firm specialising in technology which allows the last remaining reserves to be extracted from oilfields otherwise at the end of their useful life.

However, since Pachauri became a vice-chairman of the IPCC in 1997, TERI has vastly expanded its interest in every kind of renewable or sustainable technology, in many of which the various divisions of the Tata Group have also become heavily involved, such as its project to invest $1.5 billion (£930 million) in vast wind farms.
