This publication is the fourth in a series of pocketbook compilations on energy statistics designed to highlight the availability of data on various aspects of energy production, transformation and use and its linkages to other key statistics. Energy is central to the achievement of the 2030 Agenda for Sustainable Development and the Paris Agreement on climate change, and sound energy statistics are the basis for the reliable measurement of progress, thereby assisting the formulation of policy measures to achieve international and national sustainable development goals.

This outlook highlights climate-safe investment options until 2050, policies for transition and specific regional challenges. It also explores options to eventually cut emissions to zero.

The International Recommendations for Energy Statistics (IRES) have been prepared by the United Nations Statistics Division in close cooperation with countries and other international/regional organizations and adopted by the United Nations Statistical Commission in February 2011. IRES was developed to assist countries in the establishment and strengthening of their energy statistical programmes. In particular, IRES provides data compilers with a complete set of recommendations covering all aspects of the statistical production process from basic concepts, definitions, classifications and measurement units to data sources, institutional and legal framework, data compilation strategies, energy balances, data quality and statistical dissemination. It also contains the Standard International Energy Product Classification (SIEC) which is the first internationally agreed classification of energy products. IRES is a multipurpose document intended to address the need of various user groups including data producers and data users

The World Energy Outlook series is a leading source of strategic insight on the future of energy and energy-related emissions, providing detailed scenarios that map out the consequences of different energy policy and investment choices. This year's edition updates the outlooks for all fuels, technologies and regions, based on the latest market data, policy initiatives and cost trends. In addition, the 2019 report tackles some key questions in depth: (i) What do the shale revolution, the rise of liquefied natural gas, the falling costs of renewables and the spread of digital technologies mean for tomorrow's energy supply?; (ii) How can the world get on a pathway to meet global climate targets and other sustainable energy goals?; (iii) What are the energy choices that will shape Africa's future, and how might the rise of the African consumer affect global trends?; (iv) How large a role could offshore wind play in the transformation of the energy sector?; (v) Could the world's gas grids one day deliver low-carbon energy?
