GURGAON, India (Reuters) - An Indian official on Sunday complained about US pressure on India to curb its greenhouse gas emissions, but US Secretary of State Hillary Clinton emerged from their talks upbeat about a solution. There is simply no case for the pressure that we, who have among the lowest emissions per capita, face to actually reduce emissions, Jairam Ramesh, Indias minister of state for environment, told Clinton in their talks. And as if this pressure was not enough, we also face the threat of carbon tariffs on our exports to countries such as yours, he added in a statement he made to Clinton in private, repeated to journalists and then handed out to the media. The comments took some of the shine off an event that Clinton staged at a green building outside New Delhi to show the potential of energy-saving technologies. The red brick building, built by Indias ITC tobacco and hotels conglomerate, maximizes natural light and its glass lets in light but not heat, which respectively reduce the need for artificial light and air-conditioning. Making her first trip to India as secretary of state, Clinton was, however, upbeat about bridging US-Indian differences on how to curb the greenhouse gas emissions that cause global warming. We had a very fruitful discussion today, Clinton told reporters after a one-hour discussion with Ramesh. We have many more areas of agreement than perhaps had been appreciated. The United States wants big developing countries such as India and China, whose emissions are skyrocketing as their economies grow, to agree to rein them in. Developing countries say industrial nations must curb their own pollution and provide funding to help developing nations before they are asked to set limits that could crimp their economic expansion. Both sides appeared to be playing to the Indian domestic audience, with Clinton saying Washington did not wish to do anything that would reduce Indias growth and Ramesh seeking to blunt criticism his government might concede too much. Todd Stern, the US special envoy for climate change, accompanied Clinton and will hold talks over the next few days with senior Indian officials. With a new UN climate treaty due to be agreed in Copenhagen in December, tackling global warming is one of the central issues on Clintons visit to New Delhi.
