Reliance on negative-emission concepts locks in humankind's carbon addiction
The Copenhagen Accord reiterates the international community's commitment to 'hold increase in global temperature below 2 degrees Celsius'. Yet its preferred focus on emission peak dates and longer-term reduction targets, without recourse cumulative budgets, belies seriously scale scope of mitigation necessary meet such a commitment. Moreover, pivotal importance emissions from non-Annex 1 nations shaping available space for Annex pathways received, continues receive, little attention....
Despite three decades of political efforts and a wealth research on the causes catastrophic impacts climate change, global carbon dioxide emissions have continued to rise are 60% higher today than they were in 1990. Exploring this through nine thematic lenses—covering issues governance, fossil fuel industry, geopolitics, economics, mitigation modeling, energy systems, inequity, lifestyles, social imaginaries—draws out multifaceted reasons for our collective failure bend curve. However,...
The 1992 UN Framework Convention on Climate Change commits signatories to preventing 'dangerous anthropogenic interference with the climate system', leaving unspecified level of global warming that is dangerous. In late 1990s, a limit 2°C above preindustrial temperature was proposed as 'guard rail' below which most dangerous impacts could be avoided. 2009 Copenhagen Accord recognized scientific view 'that increase in should 2 degrees Celsius' despite growing views this might too high. At...
The Paris Agreement establishes an international covenant to reduce emissions in line with holding the increase temperature 'well below 2°C … and pursue 1.5°C.' Global modelling studies have repeatedly concluded that such commitments can be delivered through technocratic adjustments contemporary society, principally price mechanisms driving technical change. However, as continued rise, so these models come increasingly rely on extensive deployment of highly speculative negative technologies...
A cumulative emissions approach is increasingly used to inform mitigation policy. However, there are different interpretations of what '2°C' implies. Here it argued that cost-optimization models, commonly policy, typically underplay the urgency 2°C mitigation. The alignment within many scenarios optimistic assumptions on negative technologies (NETs), with implausibly early peak emission dates and incremental short-term mitigation, delivers outcomes commensurate commitments. In contrast,...
Since the mid-1990s, aim of keeping climate change within 2 °C has become firmly entrenched in policy discourses. In past few years, likelihood achieving it been increasingly called into question. The debate around what to do with a target that seems less and achievable is, however, only just beginning. As UN commences two-year review target, this article moves beyond somewhat binary debates about whether or not should will be met, order analyse more fully some alternative options have...
The Copenhagen Accord (and Cancun Agreement) commits the international community to "hold increase in global temperature below 2°C, and take action meet this objective consistent with science on basis of equity." This article explores implications these commitments for shipping sector. It outlines how climate change places stringent constraints sector's emissions at level while equity dimension tightens still further industry's space Annex 1 nations. mitigation potential proposed...
As nations develop policies for low-carbon transitions, conflicts with existing and planning tools are leading to competing demands land other resources. This raises fundamental questions over how multiple can best be managed. Taking the UK as an empirical example, this paper critiques current practices explore interdependencies at water-energy-food nexus. It considers uses related affect UK's resilience climate change, setting out agenda research practice relevant stakeholders in land-use...
The Paris Agreement, which entered into force in 2016, sets the ambitious climate change mitigation goal of limiting global temperature increase to below 2°C and ideally 1.5°C. This puts a severe constraint on remaining GHG emissions budget. While international shipping is also contributor anthropogenic emissions, CO2 particular, it not included Agreement. article discusses how share budget over twenty-first century could be apportioned shipping, and, using range future trade scenarios,...
Following high-profile United Nations climate summits in Glasgow and Paris, sub-national regions cities are increasingly seeking to set targets policies line with the Paris Agreement's goals. Downscaled carbon budgets a useful framework for setting local mitigation related specific global temperature change. However, doing so presents range of methodological issues, including: choices on appropriate goals set, scope emissions sectors, allocation approaches apply, whether offset credits...
Hydropower is a renewable source of electricity generation that common feature Nationally Determined Contributions (NDC), especially in developing countries. However, far from benign, research shows significant greenhouse gas (GHG) emissions emanate shallow reservoirs when they are sited the tropics. Ghana provides case study for exploring implications hydro reservoir within future energy system consistent with Paris climate objectives. Being fast-developing country, needs to generate...
