Global emissions growth appears to have slowed in the last two years. Rob Jackson and colleagues discuss the causes for this and the potential for emissions to peak in the near future.Learn more »

Limits to negative emissions

To keep global warming below 2°C, many models make extensive use of so-called Negative Emissions Technologies (NETs), which remove CO2 from the atmosphere. Pete Smith and colleagues quantify the limits to such technologies, including the requirements for land, water, nutrients, and energy. Reliance on these technologies to allow us to emit more comes with substantial risks.Learn more »

Fairness and Ambition

We are rapidly depleting the global budget for CO2 emissions determined by a 2°C limit. How do major emitters’ pledges compare to the path we must take?Learn more »

Emissions and Global Temperature Impacts

CO2 emissions are rising at a rate that could raise global temperature 2°C above preindustrial values in about 20 years and 3°C by mid-century.Learn more »

Uncertainty in temperature response to consumption

How much does today's consumption affect long-term temperature change, and how certain can we about these effects? Jonas Karstensen and colleagues present a detailed analysis.Learn more »

Allocation of global temperature change to consumers

In this article Jonas Karstensen and colleagues investigate the effects of consumption on global temperature change. While many studies focus on the well-mixed GHGs (CO2, CH4, etc.), this study includes also the so-called short-lived climate forcers such as SO2 and BC. This extended framing provides a clearer picture of the climate consequences of policy.Learn more »

Betting on Negative Emissions

Bioenergy with carbon capture and storage could be used to remove carbon dioxide from the atmosphere. However, its credibility as a climate change mitigation option is unproven and its widespread deployment in climate stabilization scenarios might become a dangerous distraction.Learn more »

A synthesis of carbon in international trade

In this comprehensive and up-to-date overview of the analysis of carbon embodied in international trade, Glen Peters and colleagues bring together treatments of some of the key issues, and introduce important new analyses. Learn more »

Persistent growth of carbon emissions

Two thirds of the CO2 emission quota consistent with a 2°C temperature limit has already been used, and the total quota will likely be exhausted in a further 30 years at the 2014 emissions rates.Learn more »

Climate Regulation in NZ

book chapter Ausseil, Kirschbaum, Andrew et al. (2014) in: Dymond (Ed.), Ecosystem Services in New Zealand: Conditions and Trends. PDF

In this chapter of a new book about ecosystem services in New Zealand, Anne-Gaëlle Ausseil and colleagues review all stocks and fluxes of carbon in New Zealand, both natural and man-made. Including energy, agriculture, albedo, erosion, forestry, and others, this analysis presents a comprehensive picture of New Zealand’s use of and influence on the global climate-regulating system.Learn more »

Undermining REDD?

Logging in the Amazon rainforest has serious consequences for the climate, and some countries are paying to help reduce deforestration through a process called REDD. But are those same countries driving the same deforestation through their own consumption patterns? Jonas Karstensen and colleagues investigate.Learn more »

New Zealand’s GHG emissions since 1861

webpage

New Zealand’s official greenhouse gas emissions inventory presents territorial emissions since 1990 as required by the UNFCCC. But what were the country’s emissions before 1990? Here Robbie Andrew has estimated emissions right back to 1861 using data scoured from a range of sources to show how New Zealand’s emissions have changed since not long after the country’s European settlement.Learn more »

The GTAP-MRIO

In this article, Robbie Andrew and Glen Peters describe work using an MRIO table derived from the GTAP database. They discuss the historical development and briefly describe its construction. They also find that carbon footprint estimates are likely to be more influenced by differences in satellite accounts than to differences in the underlying economic data.Learn more »

How to build an MRIOT from GTAP

Glen Peters and colleagues lay out clearly the method for constructing a multi-regional input-output table using the GTAP (Global Trade Analysis Project) database. Learn more »

Sharing a quota on cumulative carbon emissions

Any limit on future global warming is associated with a quota on cumulative global CO2 emissions. We translate this global carbon quota to regional and national scales, on a spectrum of sharing principles that extends from continuation of the present distribution of emissions to an equal per-capita distribution of cumulative emissions.Learn more »

Foreign carbon

The global supply chain of carbon emissions, from extraction of fossil fuels, via production through to consumption of goods and services can be long, passing through many countries along the way. Robbie Andrew and colleagues analyse the distribution of global carbon emissions at these three distinct waypoints, and argue that cross-border carbon policy options need further exploration.Learn more »

Staying below 2°C

Global emissions are tracking the most pessimistic scenarios used by the IPCC. Glen Peters and colleagues present a comparison of emissions with all four sets of scenarios used by the IPCC since 1990, and argue that inertia in both human systems and the climate system make a 2°C goal harder with every day of inaction.Learn more »

Drivers of Change in the Arctic

The Arctic is currently undergoing rapid change, to a large degree because of global warming. But how are other drivers of change expected to change in future both because of and independently of the changing climate? This detailed report summarises the current state of knowledge.Learn more »

Mapping ecosystem services

Anne-Gaëlle Ausseil and colleagues map provision of services by the environment across all of New Zealand. They then use the mapping method to assess an afforestation scenario at catchment scale to determine the consequences for the provision of a wide range of ecosystem services.Learn more »

Loss of high-class agricultural land

Development of smallholdings in New Zealand has increased in recent years, as people choose to get back to nature or escape the rat race. Robbie Andrew and John Dymond calculate how much of New Zealand’s best agricultural soils have been ‘lost’ to lifestyle blocks, and discuss what is meant by ‘loss’ in this context.Learn more »

Services from the environment to our culture

reportPDF

The field of ecosystem services describes how we benefit from the environment, including in intangible ways. While there are some established (albeit debated) methods for putting a value on some services, cultural ecosystem services are often placed in the too-hard basket. In this work, Robbie Andrew provides an overview of cultural ES, discussing the difficulties and presenting some potential solutions. Learn more »
