The document discusses the urgent need to address climate change through both mitigation and adaptation efforts. It notes that the world has less than a decade to avoid dangerous climate change. While climate change threatens all of humanity, the poor face the most severe impacts despite contributing least to emissions. The report calls for developed countries to cut emissions by 80% by 2050 and developing countries by 20% to avoid exceeding a global carbon budget. However, international cooperation on climate financing has been inadequate to address adaptation needs.

3. The world has less than a decade to avoid dangerous climate change that could bring unprecedented human development reversals Climate change is a threat to humanity as a whole. But it is the poor , a constituency with no responsibility for the ecological debt we are running up, who face the most immediate and most severe human costs The Human Development Report 2007/2008 calls for a ‘twin track’ approach that combines stringent mitigation to limit 21st Century warming to less than 2 degree centigrade , with strengthened international cooperation on adaptation The forthcoming conference of the parties in Bali is a unique opportunity to put the interests of the world’s poor and future generations at the heart of climate change negotiations

4. The 21st Century climate challenge Three distinctive characteristics: It is cumulative The effects are irreversible Large time lags – today’s emissions are tomorrow’s problems It is global

5. Risin g CO 2 emissions are pushing up sto cks & increasing temperatures In the past 100 years the earth has warmed 0.7 0 C Atmospheric concentrations of CO 2 are increasing at 1.9 ppm each year. It reached 379 ppm in 2005 Between 2000 and 2005 an average of 26 Gt of CO 2 was releases into the atmosphere each year

6. The Globa l carbon account Defining dangerous – keeping within 2°C Establishing a 21 st Century carbon budget Defining a sustainable emission’s pathway The problem of inertia – the case for adaptation

7. Th e 21 st Century carbon budg et is set at 1,456 Gt CO 2 to avoid dangerous climate change

8. The 2 1 st Century carbon budget is set for early expiry

9. Charting a course away dangerous climate change The sustainable emissions pathway is as follows The world – cuts of 50 percent by 2050 with a peak by 2020 Developed countries – cuts of 80 percent by 2050 Developing countries – cuts of 20 percent by 2050 with respect to 1990

10. Halvin g emissions by 2050 could avoid dangerous climate change

11. Some people walk more lightly than others The UK (population 60 million) emits more CO 2 than Egypt, Nigeria, Pakistan and Vietnam (total population 472 million) The state of Texas (population 23 million) has a deeper footprint than the whole sub-Saharan Africa (720 million people) The 19 million people living in New York have a deeper footprint than the 766 million people living in the 50 least developed countries The distribution of current emissions points to an inverse relationship between climate change vulnerability and responsibility

12. How many planets? The 21 st century carbon budget amounts to 1,456 Gt or around 14.5 Gt CO 2 per year Total CO 2 emissions in 2004 stood at 29 Gt If every person living in the developing world would have the same carbon footprint than an average person in the US or Canada, we would need the equivalent to nine planets to absorb the CO 2

13. Climate shocks: risk and vulnerability in an unequal world “ The countries most vulnerable are least able to protect themselves. They also contribute least to the global emissions of greenhouse gases. Without action they will pay a high price for the actions of others.” Kofi Annan “ Like slavery and apartheid, poverty is not natural. It is man-made and it can be overcome and eradicated by the actions of human beings.” Nelson Mandela

14. Risk and vulnerability Climate risk is an external fact of life for the entire world Vulnerability is a measure of capacity to manage climate hazards without suffering a long-term potentially irreversible loss of well-being. The state of human development shapes the process by which risk is converted into vulnerability

15. Disa ster risk is skewed tpwards developing countries 1 in 19 people are affected in developing countries The corresponding number is 1 in 1,500 in OECD countries A risk differential of 79

16. The human development backdrop Poverty, child mortality and malnutrition There are still around 1 billion people living on less than a dollar a day. Around 28 percent of children in LDCs are underweight or stunted. Only 32 countries (of 147) are on track to achieve the MDG on child mortality Inequality More than 80 percent of the world’s population lives in countries where income differentials are widening Underlying inequalities act as a barrier for early recovery after shocks

17. Low human development traps The potential human costs of climate change have been understated Climate related risks force people into downward spirals of disadvantage that undermine future oppurtunities In Ethiopia, childre exposed to a drought in early childhood are 36 percent more likely to be malnourished five years later – a figure that translates into 2 million additional cases of child maknutrition Indian women born during a drought or a flood in the 1970s were 19 percent less likely to ever attend primary school

18. Five h uman development tipping points Reduced agricultural productivity Heightened water insecurity Increased exposure to extreme weather events Collapse of ecosystems Increased health risks

19. Climate change will hurt deve loping country agriculture

20. Heightened water insecur ity – glacial melting Glacial melting posses threats to more than 40 percent of the world’s population. In the arid cost of Peru, 80 percent of fresh water originates from glacial melt. The flow of the Indus, could decline as much as 70 percent In Central Asia, losses of glacial melt into Amu Darya and Syr Darya rivers could restrict water for irrigation and hydroelectric power

21. Ext reme weather events The number of additional people experiencing coastal flooding could range from 134 to 332 million for a 3 o - 4 o increase in temperature. Tropical storms could raise the figure to 371 million by the end of the 21 st century Possible consequences of one meter rise in sea level In Lower Egypt, 6 million people displaced and 4,500 kms 2 of farmland flooded In Vietnam, 22 million people displaced In Bangladesh, 18 percent of land area could be inundated affecting 11 percent of the population In the Maldives, more than 80 percent of land area is less than 1 meter above sea level

22. Avoiding dangerous climate change: strategies for mitigation “ We shall require a substantially new manner of thinking if mankind is to survive.” Albert Einstein “ Speed is irrelevant if you are going in the wrong direction.” Mahatma Gandhi “ Alone we can do so little; together we can do so much.” Helen Keller

23. Avoidin g dangerous climate change – strategies for mitigation Setting mitigation targets: current problems Pricing carbon: the role of markets The role of public policy: regulation and research & development

24. Prob lems setting emission reduction targets Insufficient ambition Insufficient urgency Inaccurate indicators Inadequate sectoral coverage Inconsistent base years Targets are de-linked from policies

25. Pric ing carbon emissions Market failure: Polluters do not suffer the worse consequences of their own pollution Immediate challenge: to push the price of carbon to a level consistent with the sustainable emissions pathway Ways to do it: taxation and cap-and-trade and trade

26. Where should the price of carbon be set? How should the price be generated? Under carbon taxation emitters are required to pay for each tone of CO 2 they produce Under cap-and-trade, the government sets an overall emissions cap and issues tradable allowances to allow business the “right to emit” Taxat ion versus cap-and-trade

27. The r e lative merits of taxation and cap-and-trade Administration Price predictability Revenue mobilization The differences can be exaggerated

28. The critical role of regulation and government action The energy mix The residential sector Vehicle emission standards R&D and deployment of low carbon technologies

29. The Energy Mix Currently energy mix is dominated by fossil fuels Renewable energy is not competitive with coal-fired power – price of carbon and incentives for predicable markets can play a role Germany’ Renewable Sources Act – fix price for 20 years Spain – wind power satisfies around 8 percent of total electricity demand. In 2005 saved 19 million t CO 2 emissions Denmark – tax breaks on capital investments. In two decades wind has increased the share in electricity generation to 20 percent

30. Residential Sector Low cost mitigation In OECD residential accounts for 35-40 percent of national CO2 emissions Appliances alone produce roughly 12 percent Policies on building and appliances could save up to 29 percent emissions (3.9 Gt CO 2 ) by 2020 equivalent to three times current emissions of India Average European household could save 200 to 1000 Euros annually through energy efficiency The best efficiency standards of electrical appliances could save 322 million t CO 2 by 2010 equivalent to 100 million cars off the road (all cars from Canada, France and Germany)

31. Vehic le Emission Standards Personal transportation is the largest consumer of oil In OECD the automobile sector accounts for about 30 percent of total greenhouse gas emissions Improvements in the United States regulatory standards would represent cuttings equivalent to France’s total emissions

32. Incre a sed coal efficiency could cut CO 2 emissions

33. Adapting to the inevitable: national action and international cooperation “ If you are neutral in a situation of injustice, you have chosen the side of the oppressor.” Archbishop Desmond Tutu “ An injustice committed against anyone is a threat to everyone.” Montesquieu

34. By mid-2007, actual multilateral financing delivered through UNFCCC amounted to US$ 26 million This is equivalent to one week spending in floods defences in the UK Amounts are not the only problem. Timing and fulfillment of pledges present further limitations Towa rds adaptation apartheid? Dev eloped country investments dwarf adaptation funds

35. In v esting in adaptation up to 2015 Additional financing needs for climate proofing infrastructure and building resilience are estimated to be at least 86 billion by 2015 - Climate proofing infrastructure - Social protection - Strengthening disaster response

36. The H uman Development Report underscores that: The poo r are suffering and will suffer more with climate change. They are at gr eatest risk to face human development reversals leading to low hum an development traps. Climate change is an urgent matter. We need to act now. Both mit igation and adaptation are needed to truly fight climate change and the threats it poses to humanity. Rich co untries must cut emissions by 30% by 2020 and 80% by 2050. Internati onal cooperation on finance and technology transfer is needed. The report argues for the creation of a Climate Change Mitigatio n Facility. Extreme inequalities in adaptation capacity exist. International coopera tion has been slow to materialize. Adaptation plans needs need to be part of wider strategies of poverty alleviation.
