Decarbonisation

Achieving US climate goals requires the development and widespread deployment of all available clean energy solutions. Geothermal energy, while currently only a marginal component of the US energy economy, can contribute significantly to the climate action effort. It has the potential to support deep decarbonization through clean baseload generation, efficient heating and cooling, lithium co-production, and a host of other applications. However, current policy towards geothermal energy has, thus far, prevented the emergence of a vibrant market that would stimulate sector growth. To realize the potential of geothermal energy, public- and private-sector leaders must support policies that encourage geothermal industries and address regulatory, technical, and economic barriers. This report and accompanying two-pager make several recommendations with the potential to optimize US geothermal policy to set the sector up for a central role in the fight against climate change.

Global progress towards tackling climate change is lagging. This paper puts forward a framework to design comprehensive decarbonisation strategies while promoting growth and social inclusion. It first highlights the need of evaluating a country’s national climate targets and current policy mix, in conjunction with facilitating monitoring tools to assess current and future progress, as a key step to design effective decarbonisation strategies. It then provides a detailed comparison of several policy instruments across different assessment criteria, which indicates that no single instrument is clearly superior to all others. This highlights the need for developing decarbonisation strategies based on a wide policy mix consisting of three main components: 1) emission pricing policy instruments; 2) standards and regulations; 3) complementary policies to facilitate the reallocation of capital, labour and innovation towards low-carbon activities and to offset the adverse distributional effects of reducing emissions. However, there is no one-size-fits-all policy mix, as feasible policy choices depend on countries’ industrial structure, social preferences and political constraints. A robust and independent institutional framework, stakeholders engagement and credible communication campaigns are key to managing these constraints and ultimately enhancing public acceptance of climate mitigation policies.

This paper assesses the role of carbon pricing in a sustainable recovery from COVID-19. It tracks the policy changes in carbon pricing within OECD and G20 countries between January 2020 and August 2021 of the COVID-19 pandemic. Carbon pricing as defined here includes emissions trading schemes, fossil fuel support and carbon, fuel excise or aviation taxes. The paper also highlights the need for the recovery to be sustainable and discusses the advantages, limitations and uses of carbon pricing therein. In addition, it describes additional challenges to as well as increased rationale for carbon pricing in the pandemic. It provides evidence on the effects of carbon pricing on the challenges and discusses carbon pricing design elements to help overcome those challenges. The paper concludes that there were more policy changes with an expected negative impact on climate. However, it is likely that the impact of the climate-positive changes – which are broader in coverage and scope - will outweigh the climate-negative changes.

This report presents the modelling work quoted in the EC communication "The Paris Protocol - a blueprint for tackling global climate change beyond 2020” in the EU’s Energy Union package. It examines the effects of a Baseline scenario where current trends continue beyond 2020, and of a Global Mitigation scenario in line with keeping global warming below 2°C. The analysis uses the POLES and GEM-E3 models in a framework where economic welfare is maximised while tackling climate change. In the Baseline, emissions trigger +3.5°C global warming. In the Global Mitigation scenario, all regions realise domestic emission cuts to stay below 2°C, with various profiles in 2020-2050 depending on their national characteristics. A significant transformation of the energy systems and non-energy measures enable regions at all levels of income to move to a low-emission growth pathway. Sectors linked (directly or indirectly) to carbon-intensive processes adjust their investments to be competitive in a low-emission environment. A significant number of regions draw economic benefits from shifting their expenditures on fossil energy imports to investments. GDP growth rates are marginally affected in most regions by global efforts to reduce emissions. Crucially, high growth rates are maintained in fast-growing low-income regions. Economic costs are reduced further when countries use emission permit auction revenues for other tax reductions. Delaying actions to stay below 2°C add large economic costs.

International climate commitments and the global shift towards a decarbonized economy are challenging tried and tested models of development. This presents serious risks and opportunities for countries like Ghana, Tanzania, Guyana and Mozambique, where there are hopes that fossil fuel discoveries will transform their economies. Drawing on discussions with national governments, multilateral development banks (MDBs) and donor agencies, and a series of modelled scenarios, this paper sets out how carbon risk – defined in this paper as the economic risks associated with dependence on or exposure to high-carbon sectors – will affect developing countries with fossil fuels in the coming decades. It also makes recommendations for governments and their development partners that should enhance economic resilience and competitiveness throughout their transition.

Designing a new long-term climate strategy (LTCS) implies decisions about how to deal with important climate policy questions. These decisions will shape the strategy and therefore the European climate policy debate.
Given the different tasks an LTCS will need to perform, several coordinated strategy documents with clearly defined purposes will be needed: a sequence (or suite) of strategic documents that outline the EU’s decarbonisation strategy for different audiences.
Given the wide-ranging implications of the drive for net-zero emissions and the limited power of the European Commission to push through top-down legislation, soft instruments such as the LTCS are crucial. A transparent and participatory process in developing the LTCS is therefore vital to generate the buy-in from stakeholders that is necessary to underpin the climate policies that will meet the ambitious goals of the Paris Agreement.
