Jeremy Carl argues that despite India’s lack of a concrete binding target for significant CO2 emissions reductions, India’s climate commitments come through on other fronts.

Sometimes in diplomacy what is not announced is more revealing than what is. Such is certainly the case in India's recent climate and energy negotiations with the US, as both countries prepare to head to global climate talks in Copenhagen. The occasion of Manmohan Singh's state visit to the US brought the announcement of a flurry of energy and climate-related initiatives. These initiatives were a combination of substance and political theatre, with potentially important initiatives on environmental and regulatory capacity-building and technology partnerships buried under a deep layer of bureaucratic niceties.

What was more noticed was what was not announced: any agreement for India to have a binding target for CO2 emissions reductions, something US and European environmentalists have long claimed is necessary as part of a global effort to stave off severe climate change. And while the Indian government has eventually announced a targeted reduction in what is known as "emissions intensity", CO2 emissions per unit of GDP, that wasn't a big stretch, given India's current annual efficiency improvements. Furthermore, Minister for Environment and Forests Jairam Ramesh has made it abundantly clear in Parliament that such targets would be voluntary and not part of a binding international agreement.

With more than 60 world leaders in attendance, we can be assured that Copenhagen will not end in public failure. But the better question is whether the announced success in Copenhagen will have any practical meaning other than determining that diplomats can spin a "success" out of any actual events. Some Indian commentators have seemed to hope for a "success" of that sort - fretting about India being outmanoeuvred on the public stage by China and other developing countries that may be able to strike a more cooperative posture.

While from a tactical standpoint, such concerns are understandable (there is little reason for India to not commit to doing things it would like to do anyway, such as developing more efficient power plants or cars), from the perspective of actually taking leadership in addressing the climate problem, they mean little. In some ways, India is emulating the example of the US from the previous Kyoto climate round: while the US certainly should have been more proactive and engaged, at least the Americans had the integrity not to ratify an agreement that they couldn't keep. Many other nations could not claim that; they either missed their targets entirely, or resorted to bogus accounting tricks to meet their goals.

That India is showing its seriousness by not making climate commitments it won't live by should actually be seen as a mature and responsible decision, not an intransigent one. Does anyone think that China won't walk away from its promise if they have trouble meeting their emissions reduction goals?

As an alternative to the hot air that is likely to come out of Copenhagen, it is instructive to look at the potentially useful energy and climate agreements the US and India did sign during the PM's recent visit. The fact that clean energy was the second item listed behind security issues in the joint communiqué announced by Singh and Obama is clear evidence that both India and the US place a high importance on this aspect of their relationship.

India and the US announced numerous programmes, from the joint deployment of solar electricity in Indian cities to the strengthening of India's environmental regulatory and monitoring capacity - which is sure to be a critical step if India is to make serious and verifiable long-term commitments to emissions reductions. Perhaps most important, at least symbolically, was the announcement of joint scientific R&D work for renewable energy technologies. The Indo-US Clean Energy Research and Deployment Initiative, which promises joint development of new energy technologies and the development of a joint research centre with a public-private funding model, is one such initiative.

Ultimately, despite the bluster of diplomats in Delhi, Washington or Copenhagen, the solutions to the climate change problem must come through a technological revolution in the world's energy infrastructure. And it is here that India, with its burgeoning corps of bright young engineers, could make the biggest impact on climate change mitigation. Circumstances may not permit

India to lead the deal-making in Denmark, but if the Indian government gets serious about turning more of India's brightest young minds towards solving the clean energy problem, then India's contribution to solving the climate change conundrum may be significant indeed.

The ongoing expansion of oil palm plantations in the humid tropics, especially in Southeast Asia, is generating considerable concern and debate. Amid industry and environmental campaigners' claims, it can be hard to perceive reality. Is oil palm a valuable route to sustainable development or a costly road to environmental ruin? Inevitably, any answer depends on many choices. But do decision makers have the information they require to avoid pitfalls and make the best decisions? This review examines what we know and what we don't know about oil palm developments. Our sources include academic publications and ‘grey' literature, along with expert consultations. Some facts are indisputable: among these are that oil palm is highly productive and commercially profitable at large scales, and that palm oil demand is rising. Implementing oil palm developments involves many tradeoffs. Oil palm's considerable profitability offers wealth and development where wealth and development are needed-but also threatens traditional livelihoods. It offers a route out of poverty, while also making people vulnerable to exploitation, misinformation and market instabilities. It threatens rich biological diversity-while also offering the finance needed to protect forest. It offers a renewable source of fuel, but also threatens to increase global carbon emissions. We remain uncertain of the full implications of current choices. How can local, regional and international benefits be increased while costs are minimised? While much important information is available, it is often open to question or hard to generalise. We conclude this review with a list of pressing questions requiring further investigation. Credible, unbiased research on these issues will move the discussion and practice forward.

Recent work has shown that current bio-energy policy directives may have harmful, indirect consequences, affecting both food security and the global climate system. An additional unintended but direct effect of large-scale biofuel production is the impact on local and regional climate resulting from changes in the energy and moisture balance of the surface upon conversion to biofuel crops. Using the latest version of the WRF modeling system we conducted twenty-four, midsummer, continental-wide, sensitivity experiments by imposing realistic biophysical parameter limits appropriate for bio-energy crops in the Corn Belt of the United States. In the absence of strain/crop-specific parameterizations, a primary goal of this work was to isolate the maximum regional climate impact, for a trio of individual July months, due to land-use change resulting from bio-energy crops and to identify relative importance of each biophysical parameter in terms of its individual effect. Maximum, local changes in 2 m temperature of the order of 1C occur for the full breadth of albedo (ALB), minimum canopy resistance (RCMIN) and rooting depth (ROOT) specifications, while the regionally (105W-75W and 35N-50N) and monthly averaged response of 2 m temperature was most pronounced for the ALB and RCMIN experiments, exceeding 0.2C. The full range of the albedo variability associated with biofuel crops may be sufficient to drive regional changes in summertime rainfall. Individual parameter effects on 2 m temperature are additive, highlight the cooling contribution of higher leaf area index (LAI) and ROOT for perennial grasses (e.g., Miscanthus) versus annual crops (e.g., maize), and underscore the necessity of improving location- and vegetation-specific representation of RCMIN and ALB.

I will provide an overview of current ideas for devising a nuclear fuel cycle that minimizes proliferation risks, ranging from alternatives to the current method of spent fuel reprocessing to novel reactor designs.  While the ultimate conclusion should not be a surprise - 'proliferation-proof technology' in indeed an (double) oxymoron - it is nevertheless important to recognize the role that probabilistic risk assessment can and should play in assessing the relative merits of proposed technologies.

Dr. Robert Rosner is a visiting professor at CISAC for 2009-2010.  He is the William E. Wrather Distinguished Service Professor in the departments of Astronomy & Astrophysics and Physics at the University of Chicago.  Dr. Rosner recently stepped down as Director of Argonne National Laboratory, where he had also served as Chief Scientist.

Professor Rosner's research is mostly in the areas of plasma astrophysics and astrophysical fluid dynamics and magnetohydrodynamics (including especially solar and stellar magnetic fields); high energy density physics; boundary mixing instabilities; combustion modeling; applications of stochastic differential equations and optimization problems; and inverse methods.

"I have continued research interest overlap with the DOE/ASCI Flash Center at Chicago (which I led for its first five years); this Center has been a pioneer in the development of computational astrophysics codes with broad applicability to other disciplines; and I have been closely involved in that Center's research activities in flame modeling and interfacial mixing. I have also been involved with a Wisconsin/Chicago/Princeton NSF-supported Physics Frontier Center focusing on problems lying at the boundary of astrophysics and laboratory plasma physics, mostly in areas related to magnetohydrodynamic instabilities in low Prandtl number fluids (such as liquid metals, or stellar interiors).

"In addition over the past 7+ years -- through my work at Argonne National Laboratory - I became heavily involved in issues related to science and technology policy and management, especially in areas related to energy, climate, and modeling and simulations, national security, as well as (via my chairmanship of the Department of Energy National Laboratory Directors' Council as well as my work with the Council on Competitiveness) with national policy issues related to STEM workforce development, nuclear and renewable energy technology development, and the role of national laboratories in scientific, technological, and industrial competitiveness, including the relationship between national laboratories, academia, and industry."

Biofuels from land-rich tropical countries may help displace foreign petroleum imports for many industrialized nations, providing a possible solution to the twin challenges of energy security and climate change. But concern is mounting that crop-based biofuels will increase net greenhouse gas emissions if feedstocks are produced by expanding agricultural lands. Here we quantify the 'carbon payback time' for a range of biofuel crop expansion pathways in the tropics. We use a new, geographically detailed database of crop locations and yields, along with updated vegetation and soil biomass estimates, to provide carbon payback estimates that are more regionally specific than those in previous studies. Using this cropland database, we also estimate carbon payback times under different scenarios of future crop yields, biofuel technologies, and petroleum sources. Under current conditions, the expansion of biofuels into productive tropical ecosystems will always lead to net carbon emissions for decades to centuries, while expanding into degraded or already cultivated land will provide almost immediate carbon savings. Future crop yield improvements and technology advances, coupled with unconventional petroleum supplies, will increase biofuel carbon offsets, but clearing carbon-rich land still requires several decades or more for carbon payback. No foreseeable changes in agricultural or energy technology will be able to achieve meaningful carbon benefits if crop-based biofuels are produced at the expense of tropical forests.

Converting forest lands into bioenergy agriculture could accelerate climate change by emitting carbon stored in forests, while converting food agriculture lands into bioenergy agriculture could threaten food security. Both problems are potentially avoided by using abandoned agriculture lands for bioenergy agriculture. Here we show the global potential for bioenergy on abandoned agriculture lands to be less than 8% of current primary energy demand, based on historical land use data, satellite-derived land cover data, and global ecosystem modeling. The estimated global area of abandoned agriculture is 385-472 million hectares, or 66-110% of the areas reported in previous preliminary assessments. The area-weighted mean production of above-ground biomass is 4.3 tons/ha-1 /y-1, in contrast to estimates of up to 10 tons/ha/yr in previous assessments. The energy content of potential biomass grown on 100% of abandoned agriculture lands is less than 10% of primary energy demand for most nations in North America, Europe, and Asia, but it represents many times the energy demand in some African nations where grasslands are relatively productive and current energy demand is low.

Biofuel development contributes most effectively to rural income growth when you can have vertical integration. People all along the value chain have to be making money. The emerging connections between agriculture and energy markets are complex, but can be advantageous if handled carefully - Siwa Msangi
