The report says that advanced countries, which produced most of the greenhouse gas emissions of the past, must act to shape our climate future. If developed countries act now, a ‘climate-smart’ world is feasible, and the costs for getting there will be high but still manageable. A key way to do this is by ramping up funding for mitigation in developing countries, where most future growth in emissions will occur.
"The countries of the world must act now, act together and act differently on climate change," said World Bank President Robert B. Zoellick. "Developing countries are disproportionately affected by climate change – a crisis that is not of their making and for which they are the least prepared. For that reason, an equitable deal in Copenhagen is vitally important."
Countries need to act now because today’s decisions determine both the climate of tomorrow and the choices that shape the future. Countries need to act together because no one nation can take on the interconnected challenges posed by climate change, and global cooperation is needed to improve energy efficiencies and develop new technologies. Countries need to act differently, because we cannot plan for the future based on the climate of the past.
Developing countries will bear most of the costs of the damage from climate change. Many people in developing countries live in physically exposed locations and economically precarious conditions, and their financial and institutional capacity to adapt is limited, says the report. Already, policymakers in some developing countries note that an increasing amount of their development budget is being diverted to cope with weather-related emergencies.
At the same time, 1.6 billion people in the developing world lack access to electricity, the report notes. These developing countries—whose average per capita emissions are a fraction of those of high-income countries—need massive expansions in energy, transport, urban systems, and agricultural production. Increasing access to energy and other services using high-carbon technologies will produce more greenhouse gases, hence more climate change.
The report finds that existing low-carbon technologies and best practices could reduce energy consumption significantly, saving money. For example, the report notes that it is possible to cut energy consumption in industry and the power sector by 20–30 percent, helping reduce carbon footprints without sacrificing growth. In addition, many changes to reduce emissions of greenhouse gases also deliver significant benefits in environmental sustainability, public health, energy security, and financial savings. Avoided deforestation, for instance, preserves watersheds and protects biodiversity, while forests can effectively serve as a carbon sink.
"Developing countries face 75-80 percent of the potential damage from climate change. They urgently need help to prepare for drought, floods, and rising sea levels. They also need to intensify agricultural productivity, contain malnutrition and disease, and build climate-resilient infrastructure," said Justin Lin, World Bank Chief Economist and Senior Vice-President.
China will be one of the countries most affected by climate change. It is projected to have temperatures rising more than the world average, sea levels rising across its dense eastern seaboard, water shortages increasing in the North, weather events increasing in the South, and dramatic melting of Qinghai-Tibet glaciers that feed the country’s major rivers. In terms of managing its emissions, China has made important progress in addressing its rising trend in carbon emissions, particularly in the energy sector. China is also exerting leadership in shaping the global response to the climate change problem, in Copenhagen and beyond.
The current financial crisis cannot be an excuse to put climate on the back burner, the report warns. While financial crises may cause serious hardship and reduce growth over the short- to medium-term, they rarely last more than a few years. The threat of a warming climate is far more severe and long-lasting.
