Bangladesh, a party to the United Nations Framework Convention on Climate Change (UNFCCC), is one of the most vulnerable countries to climate change and one of the least GHG emitter. The Bangladesh Government understands the urgency and relevance of collective action to achieve the Convention’s goal of stabilizing greenhouse gas concentrations in the atmosphere at a level that would minimize the risk of severe anthropogenic interference with the climate system. As part of its global obligations, Bangladesh is going to submit this First Biennial Update Report (BUR1) to the UNFCCC.
