Abstract At COP26, India announced strong climate commitments of reaching net-zero greenhouse gas emissions by 2070. Meeting this target would likely require substantial deployment of CO 2 capture and storage (CCS) to decarbonize existing large-point sources of CO 2 . This study attempts to evaluate opportunities for deployment of CCS in India in the forthcoming decades. A geographic information system-based approach was adopted for mapping existing sources of CO 2 with the sinks. The results show that regionally-appropriate ways of moving towards CCS at scale exist in both the power and industrial sectors. Coupled analysis of these sectors with sinks shows that eight clusters may be developed throughout the country to sequester 403 Mt-CO 2 annually. These clusters are concentrated near Category-I oil basins and the Category-I coalfields (Damodar Valley), which may also create suitable financial incentives by incremental oil and coalbed methane recovery, respectively. Furthermore, a first-order costing analysis evaluates that the cost of avoidance across basins may range from –$31 to $107/t-CO 2 , depending on the type of storage reservoir and the proximity to large-point sources. A total of 12 suitable hubs and clusters were created based on annual emissions above 1 Mt-CO 2 of each large-point source and their proximity with geological sinks.

Abstract Many might say that it could not be a worse time to live in the Asia–Pacific region. In the past few years we have not only experienced the 2004 Indian Ocean tsunami, but also the 2006 Java, 2007 Solomon Islands, 2009 New Zealand, 2010 Chilean and the 2011 Tōhoku (Japan) earthquakes and tsunamis. We should not forget either the seemingly endless list of other natural hazards such as tropical cyclones and typhoons (e.g. 2010 Fiji and Philippines), volcanic eruptions (2010 Indonesia), river floods (2010 Pakistan), wildfires (2009 Australia), amongst many others. For a variety of reasons, an increasing number of people in the Asia–Pacific region are either choosing to live, or are finding themselves living, at the coast ( Sieh 2006 ). This in itself is not a problem except when they are exposed to hazards such as tsunamis and cyclones. It is in this coastal zone, though, that we have seen the recent effects of devastating natural hazards. The value of the work carried out by natural hazards researchers has recently been brought to the forefront of public awareness. It is not always easy to recognize the hazards that a low-lying coastal area faces either because there may be no previous historic records of large-magnitude, destructive tsunamis from which we might learn valuable lessons ( Satake & Atwater 2007 ) or because people are, for various reasons, unaware of the area's geological past ( Normile 2011 ). As we write this editorial, the ongoing troubles faced by the Fukushima nuclear power plant are broadcast to us daily. While it is true that the first reactor was completed there in 1971, an expert panel reviewed the plant's sesimic resistance in 2008 ( Normile 2011 ). By this time Japanese scientists were well aware of the Jogan tsunami of 869AD, an event that they concluded could recur at about 1000 year intervals. This had not been factored into the orginal design plans for the Fukushima plant, but the opportunity existed to address this issue in 2008 – it was not ( Normile 2011 ). The people of Japan and the rest of the world are now living with the aftermath of that decision.
