The Working Group III (WG III) contribution to the IPCC’s Sixth Assessment Report (AR6) assesses literature on the scientific, technological, environmental, economic and social aspects of mitigation of climate change. The report reflects new findings in the relevant literature and builds on previous IPCC reports, including the WG III contribution to the IPCC’s Fifth Assessment Report (AR5), the WG I and WG II contributions to AR6 and the three Special Reports in the Sixth Assessment cycle, as well as other UN assessments. Some of the main developments relevant for this report include an evolving international landscape, increasing diversity of actors and approaches to mitigation, close linkages between climate change mitigation, adaptation and development pathways, and increasing diversity of analytic frameworks from multiple disciplines including social sciences. Strengthened collaboration between IPCC Working Groups is reflected in Cross-Working Group boxes that integrate physical science, climate risks and adaptation, and the mitigation of climate change. The Summary for Policymakers (SPM), the Technical Summary and the entire report is available from: https://www.ipcc.ch/report/ar6/wg3/

Integrated assessment models (IAMs) connect trends in future socioeconomic and technological development with impacts on the environment, such as global climate change. They occupy a critical position at the global science‐policy interface. IAMs and associated scenarios have come under intense scrutiny, with critiques addressing both methodological and substantive issues, such as land use, carbon dioxide removal and technology performance. Criticisms have also addressed the transparency of IAM methods and assumptions as well as the transparency of the Intergovernmental Panel on Climate Change (IPCC) assessment of IAMs. This paper, authored by the co‐chairs of IPCC Working Group III and members of the Technical Support Unit, documents activities aiming to enhance the transparency of IAMs and their assessment. It includes a history of IPCC's approach to scenarios covering the formation of the Integrated Assessment Modeling Consortium (IAMC) in 2007 and the emergence of the approach by which IPCC facilitates the development of scenarios, but does not produce them itself. An IPCC Expert Meeting at the start of the current assessment cycle made transparency recommendations targeted at both the research community and IPCC. The community has taken steps to “open the black box” by moving toward open‐source and web‐publishing IAM documentation. IPCC has included an Annex to its next report focusing on scenarios and modeling methodologies. An open call for scenario data linked to the current IPCC report includes an expanded set of input and output variables. This paper ends with suggested criteria for measuring the success of these efforts to improve transparency.

Relations (IDDRI), aims to demonstrate how countries can transform their energy systems by 2050 in order to achieve a low-carbon economy and significantly reduce the global risk of catastrophic climate change. Built upon a rigorous accounting of national circumstances, the DDPP defines transparent pathways supporting the decarbonization of energy systems while respecting the specifics of national political economy and the fulfillment of domestic development priorities. The project currently comprises 16 Country Research Teams, composed of leading research institutions from countries representing about 70% of global GHG emissions and at very different stages of development. These 16 countries are: Australia, Paris. Its objective is to determine and share the keys for analyzing and understanding strategic issues linked to sustainable development from a global perspective. IDDRI helps stakeholders in deliberating on global governance of the major issues of common interest: action to attenuate climate change, to protect biodiversity, to enhance food security and to manage urbanization, and also takes part in efforts to reframe development pathways. The Sustainable Development Solutions Network (SDSN) was commissioned by UN Secretary-General Ban Ki-moon to mobilize scientific and technical expertise from academia, civil society, and the private sector to support of practical problem solving for sustainable development at local, national, and global scales. The SDSN operates national and regional networks of knowledge institutions, solution-focused thematic groups, and is building SDSNedu, an online university for sustainable development. Indian Institute of Management Ahmedabad (IIMA). IIMA, established in 1961, is India´s premier management institute and an eminently recognized international school of management education and research. IIMA's mission is to transform India and other countries through generating and propagating new ideas of global significance based on research and creation of risk-taking leader-managers who change managerial and administrative practices to enhance performance of organizations. IIMA faculty has contributed significantly to the methodological and policy relevant research in the areas such as sustainable development, health, infrastructure, energy and environment.

The anticipated economic and population growth in India will increase demand for material resources, energy and consequently carbon emissions. The global ambition to limit global warming to 1.5 °C by the end of the century calls for rapid and unprecedented action. As the most carbon-intensive sectors, India's steel and cement industry will require a more transformative shift, both on the demand and supply side. Strategies from both supply and demand-side are analysed for steel and cement sector to understand consequences for energy and emissions using two modelling approaches i) energy system and ii) material flow models. A portfolio of technically feasible options to reduce the material, energy and CO2 intensity is explored under four alternate scenarios spanning till 2050 differentiated by their mitigation ambition and development paradigm. Results show that current policies in India will provide adequate incentives for achieving the climate targets India has submitted within its Nationally Determined Contribution (NDC) however, dematerialisation, reuse and recycling will be necessary for achieving the global ambition of 1.5 °C. The study concludes that a stringent carbon policy in combination with strong sustainability principles can reduce CO2 emissions by 68% in the steel and cement sector in 1.5 °C Scenario compared to NDC Scenario.
