The International Energy Agency (IEA) is a Paris-based autonomous intergovernmental organisation, established in 1974, that provides policy recommendations, analysis and data on the entire global energy sector. The 31 member countries and 13 association countries of the IEA represent 75% of global energy demand.
Climate change mitigation is action to limit climate change by reducing emissions of greenhouse gases or removing those gases from the atmosphere. The recent rise in global average temperature is mostly due to emissions from burning fossil fuels such as coal, oil, and natural gas. Mitigation can reduce emissions by transitioning to sustainable energy sources, conserving energy, and increasing efficiency. It is possible to remove carbon dioxide from the atmosphere by enlarging forests, restoring wetlands and using other natural and technical processes. Experts call these processes carbon sequestration. Governments and companies have pledged to reduce emissions to prevent dangerous climate change in line with international negotiations to limit warming by reducing emissions.
Biomass, in the context of energy production, is matter from recently living organisms which is used for bioenergy production. Examples include wood, wood residues, energy crops, agricultural residues including straw, and organic waste from industry and households. Wood and wood residues is the largest biomass energy source today. Wood can be used as a fuel directly or processed into pellet fuel or other forms of fuels. Other plants can also be used as fuel, for instance maize, switchgrass, miscanthus and bamboo. The main waste feedstocks are wood waste, agricultural waste, municipal solid waste, and manufacturing waste. Upgrading raw biomass to higher grade fuels can be achieved by different methods, broadly classified as thermal, chemical, or biochemical.
The German Advisory Council on Global Change is an independent, scientific advisory body to the German Federal Government, established in 1992 in the run-up to the Rio Earth Summit (UNCED).
The Potsdam Institute for Climate Impact Research is a German government-funded research institute addressing crucial scientific questions in the fields of global change, climate impacts, and sustainable development. Ranked among the top environmental think tanks worldwide, it is one of the leading research institutions and part of a global network of scientific and academic institutions working on questions of global environmental change. It is a member of the Leibniz Association, whose institutions perform research on subjects of high relevance to society.
Jørgen Randers is a Norwegian academic, professor emeritus of climate strategy at the BI Norwegian Business School, and practitioner in the field of future studies. His professional field encompasses model-based futures studies, scenario analysis, system dynamics, sustainability, climate, energy and ecological economics. He is also a full member of the Club of Rome, a company director, member of various not-for-profit boards, business consultant on global sustainability matters and author. His publications include the seminal work The Limits to Growth (co-author), and Reinventing Prosperity.
Carbon dioxide removal (CDR), also known as carbon removal, greenhouse gas removal (GGR) or negative emissions, is a process in which carbon dioxide gas is removed from the atmosphere by deliberate human activities and durably stored in geological, terrestrial, or ocean reservoirs, or in products. In the context of net zero greenhouse gas emissions targets, CDR is increasingly integrated into climate policy, as an element of climate change mitigation strategies. Achieving net zero emissions will require both deep cuts in emissions and the use of CDR. CDR can counterbalance emissions that are technically difficult to eliminate, such as some agricultural and industrial emissions.
Kevin Anderson is a British climate scientist. Anderson has a decade of industrial experience, principally as an engineer in the petrochemical industry. He regularly provides advice on issues of climate change across different tiers of governance, from local and regional through to national and the European Commission.
The economics of climate change mitigation is part of the economics of climate change related to climate change mitigation, that is actions that are designed to limit the amount of long-term climate change.
Katrina Brown is a Professor of Social Sciences, at the University of Exeter. From 1991–2012, she was a Professor of Development Studies at the University of East Anglia.
Climate change scenarios or socioeconomic scenarios are projections of future greenhouse gas (GHG) emissions used by analysts to assess future vulnerability to climate change. Scenarios and pathways are created by scientists to survey any long term routes and explore the effectiveness of mitigation and helps us understand what the future may hold this will allow us to envision the future of human environment system. Producing scenarios requires estimates of future population levels, economic activity, the structure of governance, social values, and patterns of technological change. Economic and energy modelling can be used to analyze and quantify the effects of such drivers.
The Grantham Institute – Climate Change and Environment is one of five global institutes at Imperial College London and one of three Grantham-sponsored centres in the UK. The institute was founded in 2007 with a £12m donation from the Grantham Foundation for the Protection of the Environment, an organisation set up by Hannelore and Jeremy Grantham.
An energy transition is a significant structural change in an energy system regarding supply and consumption. Currently, a transition to sustainable energy is underway to limit climate change. It is also called renewable energy transition. The current transition is driven by a recognition that global greenhouse-gas emissions must be drastically reduced. This process involves phasing-down fossil fuels and re-developing whole systems to operate on low carbon electricity. A previous energy transition took place during the industrial revolution and involved an energy transition from wood and other biomass to coal, followed by oil and most recently natural gas.
Marie Corinne Lyne Le Quéré is a French-Canadian scientist. She is Royal Society Research Professor of Climate Change Science at the University of East Anglia and former Director of Tyndall Centre for Climate Change Research. She is the chair of the French High Council on Climate and member of the UK Climate Change Committee. Her research focuses on the interactions between the carbon cycle and climate change.
The contributions of women in climate change have received increasing attention in the early 21st century. Feedback from women and the issues faced by women have been described as "imperative" by the United Nations and "critical" by the Population Reference Bureau. A report by the World Health Organization concluded that incorporating gender-based analysis would "provide more effective climate change mitigation and adaptation."
James "Jim" Ferguson Skea CBE FRSE sk-EE is a British academic. He is currently Chair of the Intergovernmental Panel on Climate Change (IPCC) for its seventh assessment cycle, and a Professor of Sustainable Energy at Imperial College London. Before being elected as Chair, Skea was Co-Chair of Working Group III of the IPCC. He was a founding member of the UK Government's Committee on Climate Change and currently chairs Scotland's Just Transition Commission. He was a co-author of the IPCC 2018 Special Report on Global Warming of 1.5 °C. In July 2023, Skea was elected as Chair the IPCC.
Pete Smith is Professor of Soils and Global change at the University of Aberdeen where he directs the Scottish Climate Change Centre of Expertise, ClimateXChange.
Alice Larkin is Head of the School of Engineering at the University of Manchester and a Professor of Climate Science and Energy Policy. She works on carbon budgets and cumulative emissions. She leads the Engineering and Physical Sciences Research Council (EPSRC) consortium project Stepping Up Nexus.
