Perspectives for the Energy Transition: Investment Needs for a Low-Carbon Energy System PERSPECTIVES FOR THE ENERGY TRANSITION Investment Needs for a Low-Carbon Energy System About the IEA The International Energy Agency (IEA), an autonomous agency, was established in November 1974. Its primary mandate was – and is – two-fold: to promote energy security amongst its member countries through collective response to physical disruptions in oil supply, and provide authoritative research and analysis on ways to ensure reliable, affordable and clean energy for its Page | 1 29 member countries and beyond. The IEA carries out a comprehensive programme of energy co- operation among its member countries, each of which is obliged to hold oil stocks equivalent to 90 days of its net imports. The Agency’s aims include the following objectives: • Secure member countries’ access to reliable and ample supplies of all forms of energy; in particular, through maintaining effective emergency response capabilities in case of oil supply disruptions. • Promote sustainable energy policies that spur economic growth and environmental protection in a global context – particularly in terms of reducing greenhouse gas emissions that contribute to climate change. • Improve transparency of international markets through collection and analysis of energy data. • Support global collaboration on energy technology to secure future energy supplies and mitigate their environmental impact, including through improved energy efficiency and development and deployment of low-carbon technologies. • Find solutions to global energy challenges through engagement and dialogue with non- member countries, industry, international organisations and other stakeholders. About IRENA The International Renewable Energy Agency (IRENA) is an intergovernmental organisation that supports countries in their transition to a sustainable energy future, and serves as the principal platform for international co-operation, a centre of excellence, and a repository of policy, technology, resource and financial knowledge on renewable energy. IRENA promotes the widespread adoption and sustainable use of all forms of renewable energy, including bioenergy, geothermal, hydropower, ocean, solar and wind energy, in the pursuit of sustainable development, energy access, energy security and low-carbon economic growth and prosperity. www.irena.org This report presents the perspectives on a low-carbon energy sector of the International Energy Agency (IEA) and the International Renewable Energy Agency (IRENA).

  • A Review of Manchester's Carbon Budgets for Direct / Energy-Only
    A Review of Manchester’s Carbon Budgets for Direct / Energy-only CO2 Emissions Client: Manchester Climate Change Agency Document Reference: MCCA DIRECT Version: V.5.3 FINAL Date: February 2019 Prepared by: Dr Christopher Jones NB: All views contained with this report are attributable solely to the author and do not necessarily reflect those of researchers within the wider Tyndall Centre. 1 Introduction In June 2018 the Tyndall Centre for Climate Change Research at the University of Manchester was commissioned by Manchester Climate Change Agency to advise on science-based carbon reduction targets for Manchester. This led to the development of the Agency’s ‘Playing our Full Part’ proposal (http://www.manchesterclimate.com/targets-2018) and the formal adoption of science-based carbon reduction targets for Manchester’s direct1 /energy-only CO2 emissions by Manchester City Council, in November 2018. In November 2019 the Tyndall Centre was commissioned by the Agency to review the city’s climate change targets and recommend revised targets, as required. The review covers four areas of activity: Direct / energy-only CO2 emissions Indirect / consumption-based CO2 emissions CO2 emissions from flights from Manchester Airport Target-setting and reporting methodology for organisations and sectors The full brief is available from http://www.manchesterclimate.com/targets-2020. This report covers the review of direct /energy-only aspect of the brief in Part 1. Part 2 of this report considers a proposal for a 2030 zero carbon target. 1 This definition of ‘direct’ refers to fuel use (Scope 1) and electricity use (Scope 2) within the local authority geographic area.

  • Greenhouse Gas Mitigation in Land Use – Measuring Economic Potential
    Dominic Moran and Kimberly Pratt CHAPTER XI Greenhouse gas mitigation in land use – measuring economic potential INTRODUCTION As noted in other sections the global technical mitigation potential of agriculture, excluding fossil fuel, offsets from biomass is around 5.5–6 Gt CO2eq/year. This can be delivered through a range of technically effective measures that can be deployed in a variety of farm and land-use systems. These measures can be deployed at varying cost, including a range of ancillary environmental and social costs and benefits that need to be taken into account when moving to some consideration of the socio-economic potential of mitigation pathways. This chapter will explore the distinction between the technical and economic potential as applied more generally to land-use mitigation measures. Specifically, the chapter considers how issues of efficiency and equity are important corollaries to the effectiveness of grassland mitigation. The consideration of efficiency is made with reference to a carbon (C) price, which provides a benchmark cost for comparing mitigation options on a cost per tonne basis. The equity dimension then addresses the distributional impacts arising if efficient measures are adopted across different income groups. We demonstrate these points with the example of biochar, a soils additive that is widely considered to offer a low-cost mitigation potential applicable in a wide variety of high- and low-income farm and land use systems. This example is used to illustrate the data requirements for developing a bottom-up marginal abatement cost curve, which is essential for judging the relative effectiveness and efficient of mitigation measures.

  • Carbon City Budget” Or “Climate-Proofed Municipal Budgets”?
    Briefing / April 2020 “Carbon City budget” or “Climate-proofed municipal budgets”? What’s the difference, and how to implement them in my city. “We cannot set the right priorities with the wrong compass” Carbon budget”, “Climate-proofed municipal budgets”, “science-based targets”” are some of many different approaches offered to cities when they want to align their short, medium and long-term policies with the Paris Agreement. These instruments, measuring and monitoring tools, can be complementary. They, in any case, need to be adapted to the local context and to the local available data. Science-based targets can support cities in defining their strategy by identifying and leveraging on their own strengths; on the most impactful actions. 1. CARBON BUDGETS Carbon budgets emerged as a scientific concept from the IPCC’s 2014 Synthesis Report on Climate Change1 and relate to the “cumulative amount of CO2 emissions permitted over a period of time to keep within a 2 certain temperature threshold” . Much like a financial budget, a carbon sets out how much CO2 can be ‘spent’ over a fixed time period; and once it’s gone, it cannot be replenished (unless new technologies are rolled out at scale to extract CO2 from the atmosphere). This framing is used to inform local and national climate strategies using the 1.5°C or 2°C temperature targets as enshrined in international goals. Figure 1 tracks different interpretations given by different institutions. 1 Anderson et al.

  • Negative Emissions”: a Challenge for Climate Policy WP S Oliver Geden and Stefan Schäfer
    Introduction Stiftung Wissenschaft und Politik German Institute for International and Security Affairs Comments “Negative Emissions”: A Challenge for Climate Policy WP S Oliver Geden and Stefan Schäfer The objective of the Paris Agreement is to limit global warming to well below 2 degrees Celsius, and to pursue efforts to limit the temperature increase to 1.5 degrees. The Inter- governmental Panel on Climate Change (IPCC) believes that these targets cannot be reached through conventional mitigation measures alone. The IPCC assumes that in addition to reducing emissions, technologies for removing greenhouse gases from the atmosphere will become indispensable. The preferred technology option combines increased use of bio-energy with the capture and storage of carbon dioxide. To date, climate policy has largely ignored the necessity for “negative emissions” to achieve the temperature targets set out in the Paris Agreement. Discussions on the underlying model assumptions, potentials and risks of imaginable technological options, as well as their political implications, are only just beginning. It would be wise for the EU and Germany to proactively shape this debate and increase funding for research and devel- opment. If the Paris climate objectives are upheld, climate policy pioneers will soon be facing calls to set emission-reduction targets of much more than 100 percent – a notion that today seems paradoxical, but may soon become reality. Global climate stabilisation targets, such be consumed by the mid-2030s, the budget as restricting global warming to 1.5 or 2 for 1.5 °C as soon as the early 2020s. Since degrees Celsius (°C) above pre-industrial, completely decarbonising the world econo- are usually translated into carbon budgets my within a time frame of only 5 to 20 years that show the total amount of emissions is unrealistic, climate models build on the that would still be allowed for meeting the concept of negative emissions.
