![]() Similarly, G7 leaders agreed that “ international investments in unabated coal must stop now and we commit now to an end to new direct government support for unabated international thermal coal power generation by the end of 2021”.Ĭanada and the UK were early movers in applying the concept of CO2 abatement in their regulatory frameworks. Continuing “we have committed to rapidly scale-up technologies and policies that further accelerate the transition away from unabated coal capacity, consistent with our 2030 NDCs and net-zero commitments.” The final communique of the Leaders’ Summit stated that domestically, the group would “ commit to achieving an overwhelmingly decarbonised power system in the 2030s and to actions to accelerate this”. Both the meetings of Climate and Environment Ministers and then national Leaders signalled for the first time that G7 is committed to power sector decarbonisation and accelerating actions to move from coal to clean energy. The concept was also prominently featured in the outcomes of the recent G7 meetings convened in the UK. Phase‐out of all unabated coal and oil power plants globally by 2040.Phase‐out of unabated coal in advanced economies by 2030.No new unabated coal plants approved for development in 2021.It applied the definition highlighted above and identified the need for: The IEA’s Net Zero Energy report analysed milestones for emissions reduction and sectoral transformation to enable the world to achieve net-zero emissions by 2050. This regulatory approach puts the onus on power plant owners and operators to either fit CCS technology or retire the power plant. These definitions consistently recognise the purpose of abatement is to reduce CO2 emissions to defined levels additional technology investments are necessary to achieve this in the absence of such measures, coal power generation should cease. In February 2020 the UK announced it would bring forward the date for the end of unabated coal power generation from 2025 to 2024, noting that “Unabated means that the plant has not invested in abating technology, such as carbon capture and storage.”.The G7 press release alongside the 2021 Leaders’ meeting communique stated “Unabated coal power generation refers to the use of coal that isn’t mitigated with technologies to reduce the CO2 emissions, such as Carbon Capture Utilisation and Storage (CCUS)”.The IEA has used this definition for years – for example, in its 2016 World Energy Outlook (p28), it already stated that “ the long-term future of coal is increasingly tied to the commercial availability of carbon capture and storage, as only abated coal use is compatible with deep decarbonisation“ The IEA Net Zero report (p193): “C onsumption of fossil fuels in facilities without CCUS are classified as “unabated””.Indeed, abatement is consistently referred to in these terms, as can be seen in these examples: So in converse, ‘unabated coal’ means coal power plant without CC(U)S technology equipment. In the case of coal power generation, abatement is generally understood to mean the use of Carbon Capture and Storage (CCS), or Carbon Capture, Utilisation and Storage (CCUS) technology. Reducing emissions from ‘unabated coal’ power generation Furthermore, it recognises that no matter how efficient the underlying process may be, it will still result in unacceptable levels of environmental pollution, thereby requiring additional measures to be taken. It requires the application of an additional technology or process that is different to the process that is the source of the pollution. It is important to note that pollution abatement is goal-oriented (reducing harmful pollution to defined levels). So ‘unabated’ refers to the underlying industrial process prior to (or in the absence of) the application of pollution control measures. ![]() The most commonly used technologies are scrubbers, noise mufflers, filters, incinerators, waste-water treatment facilities and composting of wastes.” “Pollution abatement refers to technology applied or measure taken to reduce pollution and/or its impacts on the environment. The concept of pollution abatement has been common in environmental regulation for decades, with the OECD defining it as: To abate = to reduce in degree or intensityĪbatement = the act or process of reducing or otherwise abating something abatement of pollution
