Climate and Equity: a bird’s eye view

7 Climate challenge … in the midst of a development crisis? Nearly 2 million per year die from lung diseases due to cooking smoke About 800 million people chronically undernourished More than 1 billion have poor access to fresh water 2 million children die per year from diarrhea 30,000 deaths each day from preventable diseases 3 billion people without access to clean cooking fuel, electricity, or both

When do emissions have to peak and start falling? No. America/W. Eur AsiaLatin America Middle East/Africa Economies Japan/Aus/New Z in Transition Emissions peak, globally and in all regions, in next ~10 years in the “likely 2°C” category of paths. → Broad low-GHG transformation underway in all regions. 8 IPCC AR5 WGIII, Ch. 6 Figure 6.7

 No single country can protect “its own” climate by reducing its own emissions  No country can solve its own climate problem for itself.  Countries must persuade other countries to help it solve its climate problem  A country thus reduces its own emissions – and cooperates in other ways – for the sake of inducing reciprocal effort (that is, getting other countries to do likewise).  A country is more likely to be successful if it is perceived as doing its fair share of the effort.  So, international cooperation with equitable effort-sharing is more likely to be agreed and successfully implemented. “Outcomes seen as equitable can lead to more effective cooperation.” [IPCC, Summary for Policy Makers, 2014] Why a global climate response must be fair to be effective:

“The Parties should protect the climate system for the benefit of present and future generations of humankind, on the basis of equity and in accordance with their common but differentiated responsibilities and respective capabilities.” Principles, Article 3.1, UNFCCC,

Principle 7, Rio Declaration, 1992 “In view of the different contributions to global environmental degradation, States have common but differentiated responsibilities. The developed countries acknowledge the responsibility that they bear in the international pursuit of sustainable development in view of the pressures their societies place on the global environment and of the technologies and financial resources they command.” 12

13 “Countries will be asked to meet different requirements based upon their historical share or contribution to the problem and their relative ability to carry the burden of change. This precedent is well established in international law, and there is no other way to do it.” Al Gore

23 Summary Comments The science is unambiguous. The climate is changing, and it presents severe risks. It is technically and economically possible to reduce emissions rapidly enough to keep warming below 2°C. It would mean carbon-based development is no longer an option in the North, nor in the South. A global transition to low emission future is likely to be achieved only if it is done cooperatively and in a way that is widely perceived to be fair. In the developed countries, deep emissions reductions are important and necessary. But only part of the story… Earnest efforts to enable the climate transition to occur globally, through cooperation with the developing countries through technology & financial support are equally crucial. (And won’t ruin our economies.) This isn’t just about equity and justice… it’s about being realistic about what is needed to preserve our own futures.

24 Some questions Trade-offs or interdependencies? Where are there indeed trade-offs between environmental sustainability and equity? Where is one dependent on the other? Is there a “tech-fix?” Can questions of lifestyle, behavior, and distribution be put aside? Can an environmentally sustainable world co-exist with radical disparities in consumption? (Does environmental sustainability look like hydrogen-fueled Hummers driving between elite enclaves)? Is there a “policy tweak”? Can we avoid questions of political and economic structure? Do disparities in political and economic power need to be corrected? (Can we achieve environmental sustainability with a nominal carbon tax and better informed consumers?) Cooperative or competitive futures? At what point does a cooperative global solution move out of reach? What will make us tip toward a “we’re all in this together” response versus “devil take the hindmost” response? What do we do now that is setting the stage for one future or the other?
