The German climate change programme (2000) identified the residential sector as one of the main sectors in which to achieve additional GHG reductions. Our case study compiles results of existing evaluations of the key policies and measures that were planned and introduced and carries out some own estimates of achievements. We show, which emission reductions and which instruments where planned and what was delivered until 2004.
Legal instruments such as the revised building code were introduced later than planned and their effects will - at least partly - fall behind expectations. Other legal instruments such as minimum energy performance standards for domestic appliances etc. were - in spite of the programme - not implemented yet.
On the other hand, substantial financial incentives were introduced. Especially schemes granting low-interest loans for building renovation were introduced. However tax subsidies for low-energy buildings were phased out.
In general we can conclude from our case study that Germany was not able to compensate for the slower or restricted implementation of legal instruments through the introduction of financial incentives. Particularly the efficient use of electricity has been left aside as almost no further policy action was taken since 2001.
Thus energy efficiency in the residential sector will not deliver the GHG reductions planned for in the German climate change programme until 2005. From our findings we draw conclusions and recommendations towards policy makers: Which lessons are to be learnt and what has to be done in order to fully harness EE potentials in residential sector as planned for 2010?
There is an extensive potential for GHG emission reductions in the new EU member states and the EU accession countries by improving energy efficiency, investing in renewable energy supply and other measures, part of which could be tapped by JI. However, the EU Emissions Trading System (EU ETS) and especially the recently adopted "Linking Directive" is probably going to have a significant impact on this JI potential. Especially two provisions are important:
The baseline of a project has to be based on the acquis communautaire, the environmental regulations of which are substantially higher than the Accession Countries' existing ones. Projects, which directly or indirectly reduce emissions from installations falling within the scope of the EU ETS, can only generate certificates if an equal number of EU allowances are cancelled. JI is thus put into direct competition with the EU ETS. In this paper we analyse the impact of these provisions first in theory and then country by country for six Central and East European countries that recently acceded the EU or are candidates for accession. As a result, we give an overview of the potential and the limitations of JI as an instrument for achieving emission reductions in the selected Accession Countries and provide important overview information to policy makers.
Toothless tiger? : Is the EU action plan on energy efficiency sufficient to reach its target?
(2007)
Motivated by, inter alia, the increasing energy prices, the security of energy supply and climate change, the new EU "Action Plan for Energy Efficiency: Realising the Potential" (EEAP), sets out the policies and measures required to be implemented over the next six years to achieve the EU's goal of reducing annual primary energy consumption by about 20 % by 2020. By increasing energy efficiency, the security of energy supply and the reduction of carbon emissions are also improved.
The paper will analyse the 20 % target of the new EEAP for the energy demand side by comparison with different recent energy scenarios for the EU. It will therefore review the recommended policies and measures and examine, in which energy demand sectors energy efficiency may be increased and to which extend. The main focus is whether the recommended policies and actions will be sufficient and which additional measures may be useful, if additional measures are needed.
Phasing out coal in the German energy sector : interdependencies, challenges and potential solutions
(2019)
Relevant aspects of the options and requirements for reducing and phasing out coal-fired power generation have been under debate for several years. This process has produced a range of strategies, analyses and arguments, outlining how coal use in the energy sector could be reduced and phased out in the planned time frame, and determining structural policy measures suitable to support this. This Coal Report studies the existing analyses and provides an overview of the state of debate. It is intended to provide information on facts and contexts, present the advantages and disadvantages of individual courses of action, and reveal the respective scientific backgrounds. It strives to take a scientific and independent approach, and present facts in concise language, making it easy to follow for readers who are not experts in the field, without excessive abridgements or provocative statements.
Using natural gas for fuel releases less carbon dioxide per unit of energy produced than burning oil or coal, but its production and transport are accompanied by emissions of methane, which is a much more potent greenhouse gas than carbon dioxide in the short term. This calls into question whether climate forcing could be reduced by switching from coal and oil to natural gas. We have made measurements in Russia along the world's largest gas-transport system and find that methane leakage is in the region of 1.4%, which is considerably less than expected and comparable to that from systems in the United States. Our calculations indicate that using natural gas in preference to other fossil fuels could be useful in the short term for mitigating climate change.
Based on a comprehensive scenario analysis of the EU's GHG emissions by 2020, we show that the 20% energy savings target set in the Action Plan "Doing more with less" in 2006 is still the most significant and thus indispensable strategy element within an ambitious EU climate and energy strategy targeting at a 30% reduction of GHG emissions by 2020.
The scenario analysis provides a sector by sector projection of potential future energy use and GHG emissions, combined with a detailed policy analysis of the core policies on energy efficiency by the EU and its Member States taken from current research results by the authors and others.
Consequently the paper identifies and quantifies the current implementation deficit in the EU and shows that, despite of sufficient targets, implementation is still significantly lacking in almost all fields of energy efficiency. Some, e.g. transport sector and buildings, are still substantially far from receiving the necessary political impetus. The paper also demonstrates co-benefits of a strong energy efficiency strategy, e.g. the achievability of the targets of the RES directive, which crucially depends on a strong efficiency policy.
We conclude that the efforts of the energy efficiency policy of the EU and its Member States have to be significantly intensfied. As proposed by the EU in case that other developed and key developing countries take up comparable targets in order to fulfil its role in the climate and energy strategy. To achieve this, we offer an analysis of the current weaknesses of EU energy efficiency policy and derive recommendations on how the EU can still reach its targets for 2020.
