Climate Changer

Recently in Heiligendamm (Germany) was the latest G8 summit. Probably many of you will be interested in the declaration of the G8 summit, which was agreed yesterday by the leaders of the G8 countries. As usual we refrain from a political analysis, but as scientists we note that it is rewarding to see that the results of climate science are fully acknowledged by the heads of state. The leading industrialised nations (G8) aim to at least halve global CO2 emissions by 2050. The Heads of State and Government agreed at Heiligendamm to achieve this goal together as part of a UN process. The big emerging economies are also to be incorporated in the process.The so-called IPCC Report found that global warming is largely the result of human activity. Only by limiting CO2 emissions will it be possible to stop global warming. In order to avoid wide-ranging consequences, the international experts believe that it is absolutely essential that global warming be limited to 1.5 to 2.5°C (UN Climate Report: Joint global action is required). The Group of 8 industrialised nations recognise the statements and goals in the IPPC Report. “Now we need to work together to get as many countries as possible across the world to undertake to do something,” the German Chancellor said.

The declaration states:

CLIMATE CHANGE

48. We take note of and are concerned about the recent UN Intergovernmental Panel on Climate Change (IPCC) reports. The most recent report concluded both, that global temperatures are rising, that this is caused largely by human activities and, in addition,that for increases in global average temperature, there are projected to be major changes in ecosystem structure and function with predominantly negative consequences for biodiversity and ecosystems, e.g. water and food supply.

Fighting Climate Change

49. We are therefore committed to taking strong and early action to tackle climate change in order to stabilize greenhouse gas concentrations at a level that would prevent dangerous anthropogenic interference with the climate system. Taking into account the scientific knowledge as represented in the recent IPCC reports, global greenhouse gas emissions must stop rising, followed by substantial global emission reductions. In setting a global goal for emissions reductions in the process we have agreed today involving all major emitters, we will consider seriously the decisions made by the European Union, Canada and Japan which include at least a halving of global emissions by 2050. We commit to achieving these goals and invite the major emerging economies to join us in this endeavour.

50. As climate change is a global problem, the response to it needs to be international. We welcome the wide range of existing activities both in industrialised and developing countries. We share a long-term vision and agree on the need for frameworks that will accelerate action over the next decade. Complementary national, regional and global policy frameworks that co-ordinate rather than compete with each other will strengthen the effectiveness of the measures. Such frameworks must address not only climate change but also energy security, economic growth, and sustainable development objectives in an integrated approach. They will provide important orientation for the necessary future investment decisions.

51. We stress that further action should be based on the UNFCCC principle of common but differentiated responsibilities and respective capabilities. We reaffirm, as G8 leaders, our responsibility to act. We acknowledge the continuing leadership role that developed economies have to play in any future climate change efforts to reduce global emissions, so that all countries undertake effective climate commitments tailored to their particular situations. We recognise however, that the efforts of developed economies will not be sufficient and that new approaches for contributions by other countries are needed. Against this background, we invite notably the emerging economies to address the increase in their emissions by reducing the carbon intensity of their economic development. Action of emerging economies could take several forms, such as sustainable development policies and measures, an improved and strengthened clean development mechanism, the setting up of plans for the sectors that generate most pollution so as to reduce their greenhouse gas emissions compared with a business as usual scenario.

52. We acknowledge that the UN climate process is the appropriate forum for negotiating future global action on climate change. We are committed to moving forward in that forum and call on all parties to actively and constructively participate in the UN Climate Change Conference in Indonesia in December 2007 with a view to achieving a comprehensive post 2012-agreement (post Kyoto-agreement) that should include all major emitters.

53. To address the urgent challenge of climate change, it is vital that major economies that use the most energy and generate the majority of greenhouse gas emissions agree on a detailed contribution for a new global framework by the end of 2008 which would contribute to a global agreement under the UNFCCC by 2009. We therefore reiterate the need to engage major emitting economies on how best to address the challenge of climate change. We embrace efforts to work with these countries on long term strategies. To this end, our representatives have already met with the representatives of Brazil, China, India, Mexico and South Africa in Berlin on 4 May 2007. We will continue to meet with high representatives of these and other major energy consuming and greenhouse gas emitting countries to consider the necessary components for successfully combating climate change. We welcome the offer of the United States to host such a meeting later this year. This major emitters’ process should include, inter alia, national, regional and international policies, targets and plans, in line with national circumstances, an ambitious work program within the UNFCCC, and the development and deployment of climate-friendly technology. This dialogue will support the UN climate process and report back to the UNFCCC.
