Continued global action on climate change has major consequences for fossil fuel markets, especially for coal as the most carbon-intensive fuel. This article summarizes current market developments in the most important coal-producing and coal-consuming countries, resulting in a critical qualitative assessment of prospects for future coal exports. Colombia, as the world’s fourth largest exporter, is strongly affected by these global trends, with more than 90% of its production being exported. Market analysis finds Colombia in a strong competitive position, owing to its low production costs and high coal quality. Nevertheless, market trends and enhanced climate policies suggest a gloomy outlook for future exports. Increasing competition on the Atlantic as well as Pacific market will keep coal prices low and continue pressure on mining companies. Increasing numbers of filed bankruptcies and lay-offs might be just the beginning of a carbon bubble devaluing fossil fuel investments and leaving them stranded. Colombia largely supplies European and Mediterranean consumers but also delivers some quantities to the US Gulf Coast, and to Central and South America. Future coal demand in most of these countries will continue to decline in the next decades. Newly constructed power plants in emerging economies (India, China) are unlikely to compensate for this downturn owing to increasing domestic supply and decreasing demand. Therefore, maintaining or even increasing mining volumes in Colombia should be re-evaluated, taking into account new economic realities as well as local externalities. Ignoring these risks could lead to additional stranded investments, aggravating the local resource curse and hampering sustainable economic development.

Key policy insights
  • The climate policies of most of Colombia’s traditional trade partners target steam coal as the more emission-intensive fossil fuel, with many countries implementing or considering a coal phase-out.

  • Coal exporters should re-evaluate their operations and new investments taking into account this new policy environment.

  • To prevent a race to the bottom among coal producers that would favour weak regulation, climate policy makers should also consider the local social and external costs of coal mining, including on health and the local environment.

The Paris Agreement is the last hope to keep global temperature rise below 2°C. The consensus agrees to holding the increase in global average temperature to well below 2°C above pre-industrial levels, and to aim for 1.5°C. Each Party’s successive nationally determined contribution (NDC) will represent a progression beyond the party’s then current NDC, and reflect its highest possible ambition. Using Ireland as a test case, we show that increased mitigation ambition is required to meet the Paris Agreement goals in contrast to current EU policy goals of an 80–95% reduction by 2050. For the 1.5°C consistent carbon budgets, the technically feasible scenarios' abatement costs rise to greater than €8,100/tCO2 by 2050. The greatest economic impact is in the short term. Annual GDP growth rates in the period to 2020 reduce from 4% to 2.2% in the 1.5°C scenario. While aiming for net zero emissions beyond 2050, investment decisions in the next 5–10 years are critical to prevent carbon lock-in.

Key policy insights

  • Economic growth can be maintained in Ireland while rapidly decarbonizing the energy system.

  • The social cost of carbon needs to be included as standard in valuation of infrastructure investment planning, both by government finance departments and private investors.

  • Technological feasibility is not the limiting factor in achieving rapid deep decarbonization.

  • Immediate increased decarbonization ambition over the next 3–5 years is critical to achieve the Paris Agreement goals, acknowledging the current 80–95% reduction target is not consistent with temperature goals of ‘well below’ 2°C and pursuing 1.5°C.

  • Applying carbon budgets to the energy system results in non-linear CO2 emissions reductions over time, which contrast with current EU policy targets, and the implied optimal climate policy and mitigation investment strategy.

It is imperative that climate, energy, and sustainability policy researchers and practitioners grapple with the difficulty of decarbonizing heat, which remains the largest single end-use energy service worldwide. In this study, based on a comparative assessment of five original and representative national surveys in Germany, Italy, Spain, Sweden, and the United Kingdom (N = 10,109), we explore public attitudes of household heat decarbonization in Europe. We explore how people conceive of the purposes of low-carbon heat, their preferences for particular forms of heat supply, and their (at times odd) practices of heat consumption and temperature settings. The data reveal four significant challenges to heat decarbonization that are consistent across geographies: 1) High satisfaction with existing, often fossil fuel based, heating systems; 2) Varying and divergent preferences and expectations for thermal comfort; 3) Householders unlikely to change their heating system in the near-term, in part driven by low familiarity and knowledge of alternative systems; and 4) heat satisfaction appears lower as the fuel mix is decarbonized. The paper concludes by connecting these findings with policy and research implications.  相似文献
