Co-benefits

Reducing CO2 would reduce the abundance of air pollutants as well, because a major part of these are co-emitted by the same sources, like coal-fired power plants. Reduced air pollution leads to lower health hazards and lower damage to ecosystems and agriculture. From a different angle, the ‘co-benefits’ of reducing air pollution by reducing CO2 emissions can be an important element of climate policy, making these policies effectively cheaper, by removing the need for policies and technologies to filter out air pollutants. Other co-benefits are also subject to active research, like reduced dependence on fossil-fuel imports as a result of strategies to move away from fossil-fuel use in a transition to higher reliance on renewable energy technology.

Deutschland wird seine nationalen Ziele verstärken und geeignete Maßnahmen ergreifen müssen, um die Ziele des Pariser Klimaabkommens zu erreichen. Dies wird laut der Studie von Climate Analytics, im Auftrag von Agora Verkehrswende, erhebliche Anstrengungen im Verkehrssektor erfordern. Auch das bevölkerungsreichste Land der EU wird sich seiner Verantwortung stellen müssen.  
Climate change will be the greatest threat to humanity and global ecosystems in the coming years, and there is a pressing need to understand and communicate the impacts of warming, across the perspectives of the natural and social sciences. Hoegh-Guldberg et al. review the climate change–impact literature, expanding on the recent report of the Intergovernmental Panel on Climate Change. They provide evidence of the impacts of warming at 1°, 1.5°, and 2°C—and higher—for the physical system, ecosystems, agriculture, and human livelihoods. The benefits of limiting climate change to no more than 1.5°C above preindustrial levels would outweigh the costs.  
Shifting energy supply in South Asia and South East Asia to non-fossil fuel-based energy systems in line with the Paris Agreement long-term temperature goal and achievement of Sustainable Development Goals  
Together with the Australian Conservation Foundation, we have been analysing Australia’s emissions profile and policies. This factsheet focuses on Australia’s vehicle fleet and outlines how it compares with other countries, breaks down the main sources of vehicle emissions and evaluates whether there are policies in place to decarbonise the sector.  
Germany needs to phase coal out of its electricity sector by 2030 to meet its obligations under the Paris Agreement. This is earlier than the dates discussed so far by the Coal Commission, a body established to come up with a coal exit plan by the end of 2018. If Germany follows the Paris Agreement compatible pathway we propose here, it can also make significant steps towards meeting its 2020 emission reduction targets – something seen as impossible at the moment. Under a planned and structured coal phase out, energy security and reliability of electricity supply is not expected to be a major concern and will be manageable. As well as reduced health impacts, a coal exit from electricity generation by 2030 in Germany will bring added benefits in job creation, helping to smooth the transition to a zero-carbon energy system.  

Projects

The project aims to investigate how changes in land cover and land management can help to meet the mitigation and adaptation objectives of the Paris Agreement, as well as the Sustainable Development Goals. The project partners findings will be disseminated through a number of tools, events and products and by closely involving stakeholders and policy-makers, with the aim to support sustainable land use decision-making.
