Climate | Energy

Climate change brought about by the sharp rise in greenhouse gas emissions since the beginning of the industrial era is a global challenge that the community of nations is hoping can be mastered via an effective international climate protection treaty that is slated to take effect in 2020. The top priority in this regard is greenhouse gas emission reductions. The goal of German energy policy is to reduce such emissions by at least 40 percent by 2020 and by 80 to 95 percent by 2050, relative to 1990 levels. The measures in this regard aim to increase the use of renewable energy and improve energy efficiency.

If we are to have any hope of reducing greenhouse gases, we will need to substantially roll back energy use, improve energy efficiency and at the same time ramp up renewable energy production and use. To leverage this potential, we need to institute efficiency measures and optimize renewable energy technologies. But to do this, it is crucial that economic, infrastructure and political obstacles be overcome.

What is the key to the success of climate protection measures? Timely, sustainable infrastructure investments worldwide that will create conditions early on and in a timely manner that will be conducive to adherence to the two degree ceiling. Hence transformation of our economic systems and their underlying socioeconomic structures (energy systems, urbanization and land use) will need to begin at the national level, and then continue based on an across the board sustainable-development paradigm on the global level. As a society, we need to be very clear about the fact that climate protection cannot and will not be achieved through technical solutions alone, and will instead necessitate fundamental transformation of our lifestyles, "mentalités", and values.

In the interest of moving toward achieving these goals, in 2010 the German government adopted an ambitious energy infrastructure transformation program that sets a long term strategy for German energy and climate policy. We at the UBA are supporting this process through our own investigations of long term scenarios aimed at energy efficiency, the use of renewable energy, and energy-infrastructure transformation monitoring. To this end, we are implementing instruments such as carbon trading, the guarantee of origin register, and the "Blauer Engel" seal of environmental quality.

Rebound effects

Efficiency increase oftentimes reduces product or service costs, which can in turn ramp up consumption (due to reduced prices), thus partly canceling out the original savings. This is known as the rebound effect. read more


Geo-Engineering: Proposals for international governance

atmosphere of the Earth

A number of schemes have been developed in recent years to combat global warming through intervention into the climate system. What these geo-engineering measures have in common is the risks they harbour for man and the environment which can have an impact worldwide and should therefore be subject to global governance. A study done on behalf of the UBA presents appropriate proposals. read more
