Secretary-General Kofi Annan has stressed that developed countries, particularly the United States -- the world's leading emitter of greenhouses gases -- must take the helm in stemming global climate change.
Delivering the commencement address to the Fletcher School of Law and Diplomacy in Medford,Massachusetts, on Sunday, Mr. Annan noted that the US, which produced the most greenhousegases largely because it was the world's most successful economy, must "join in reducing emissions and in the broader quest for energy efficiency and conservation."
