Greenhouse gas emissions from current and enhanced policies of China until 2030: Can emissions peak before 2030?

In June 2015, China announced its post-2020 reduction targets, its central element being the intention to peak CO 2 emissions by 2030 or earlier. China has implemented several policies to reduce its…

Global Carbon Budget 2015

Accurate assessment of anthropogenic carbon dioxide (CO 2 ) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere is important to better understand the global…

Raising the ambition level of INDCs allows for a smoother energy transition

This note presents preliminary calculations on the implications of the INDCs for the long-term international climate goal of keeping global temperature increase below 2 °C, compared to pre-industrial…

Implications of long-term scenarios for medium-term targets (2050)

If fast and substantial reduction of greenhouse gas emissions is postponed further, there are fewer options available to stay below a 2 °C warming at the end of the century. Delayed action is likely…

Landscape restoration: New directions in global governance

Worldwide, though in some regions more than others, the quality of land is degrading, reducing its ability to provide ecosystem services humanity depends on for its existence. In view of this trend…

Exploring resource efficiency for energy, land and phosphorus use: Implications for resource scarcity and the global environment

In this paper, we present four model-based scenarios exploring the potential for resource efficiency for energy, land and phosphorus use, and implications for resource depletion, climate change and…

Trends in global CO2 emissions: 2015 report

After a decade of annual increases of 4%, on average, and two years (2012 and 2013) of slowing down to about 1%, the growth in global CO 2 emissions almost stalled, increasing by only 0.5% in 2014…

CO2 emissions from fuel combustion Part III: Total Greenhouse Gas Emissions; 2015 Edition

To show the changes in energy-related CO 2 emission in response to economic and policy developments, the annual reference publication “CO 2 emissions from fuel combustion” by the International Energy…

Assessing Intended Nationally Determined Contributions to the Paris Climate Agreement

Climate plans submitted by countries in the run-up to the Paris Summit could, if fully implemented, deliver significant reductions in the emission of greenhouse gases. Without new climate policy, the…

Transport: A roadblock to climate change mitigation?

Global emissions scenarios studies, such as those informing the Intergovernmental Panel on Climate Change (IPCC) 5th Assessment Report (AR5), highlight the importance of the transport sector for…
