Global Climate Change Regulations
One hundred and eighty-six nations have ratified the 1992 Framework Convention on Climate Change (UNFCCC), responding to the long-term challenge of climate change and the contribution of greenhouse gas emissions from human sources. DuPont has participated in international scientific study of climate change and believes there is need for prudent action. We began taking action to reduce greenhouse gas emissions in the early 1990s, have accomplished major global reductions and set ambitious goals for the current decade. We intend to meet those goals.
The UNFCCC defines the objectives governments have agreed to, and provides a structure for legal agreements to begin to address these objectives. The Kyoto Protocol is one of these legal agreements. Many developed countries are beginning to enact regulations to implement their commitments under the agreement, and HFCs are among the greenhouse gases to be controlled under the Kyoto Protocol.
The primary contributor to global climate change is carbon dioxide emitted to the atmosphere when coal, oil or natural gas is burned to produce energy. When they escape to the atmosphere, HFCs also contribute to climate change. Although a lesser contributor because their net emissions are relatively small, on a kilogram-for-kilogram basis HFCs have larger relative impacts as compared to carbon dioxide. For this reason their emissions to the atmosphere should be controlled. DuPont has participated with others in the industry, as well as national and international organizations, to develop Responsible Use Principles for HFCs. In addition, some governments are beginning to implement regulations to control emissions.
