We are happy to introduce the Handbook of Charcoal-Making, a comprehensive survey written by a competent expert with international experience. The book was prepared by the Commission of the European Communities in the frame of its R + D programme on biomass. In the European Community today the biomass option is only little developed: a huge resource is waiting for use. Actually, there is ample scope for biomass utilisation as it bears promise in some of the vital sectors of modern society. Development of indigenous and renewable energy sources, creation of new employment, recycling of wastes and improvement of the environment, restructuring of European agriculture, development of the Third World, they are all concerned. It is important to note that the exploitation of the biomass resource is largely related to its conversion into a marketable product. However, as many of the conversion technologies are not yet well established or need improvement, R + D is more than ever the critical pathway to get access to the benefits of biomass utilisation. In the European Communities I R + D programme, thermal conversion of biomass is developed with priority. Gasification as well as pyrolysis development projects are being supported by the Commission in European industry and universities. Pyrolysis is particularly attractive because the conversion products charcoal and pyrolytic oil are very convenient in use, technologies are relatively simple and projected pay-back times favourable. -v- Charcoal making is just the simplest and oldest form of pyrolysis.

Charcoal is widely used for cooking and heating in developing countries. The consumption of charcoal has been at high level and the demand may keep growing over the next decades, particularly in sub-Saharan Africa. Some preliminary studies indicate that among commonly used cooking fuels, unsustainably produced charcoal can be the most greenhouse gas intensive fuels and simple measures could deliver high GHG mitigation benefits. Through the Paris Agreement on climate change adopted in 2015, countries set themselves ambitious targets to curb climate change, and forest-related measures have an important role to play in climate change mitigation and adaptation. Over 70% of the countries who have submitted their (intended) nationally determined contributions (NDCs) mention forestry and land use mitigation measures. Despite the importance of woodfuel in many countries, few have explicitly included measures to reduce emissions from woodfuel production and consumption. Many of the NDCs that include forestry do not yet provide detailed information on how mitigation is to be achieved. The overall objective of the publication is to provide data and information to allow for informed decision-making on the contribution sustainable charcoal production and consumption can make to climate change mitigation. More specifically, the publication aims to answer the following questions: - What are the climate change impacts of the current practices on charcoal production and consumption worldwide and across regions? - What is the potential of sustainable charcoal production in GHG emission reductions and how such potential can be achieved? - What are the key barriers to sustainable charcoal production and what actions are required to develop a climate-smart charcoal sector?

The increasing importance of biomass as a renewable energy source has lead to an acute need for reliable and detailed information on its assessment, consumption and supply. Responding to this need, and overcoming the lack of standardized measurement and accounting procedures, this handbook provides the reader with the skills to understand the biomass resource base, the tools to assess the resource, and explores the pros and cons of exploitation. Topics covered include assessment methods for woody and herbaceous biomass, biomass supply and consumption, remote sensing techniques as well as vital policy issues. International case studies, ranging from techniques for measuring tree volume to transporting biomass, help to illustrate step-by-step methods and are based on field work experience. Technical appendices offer a glossary of terms, energy units and other valuable resource data.

Key messagesWoodfuel, particularly charcoal, is an important energy source in urban areas and a livelihood source in rural areas.Actors in the Baringo–Nairobi charcoal value chain get between KES 107 and 613 per bag of charcoal depending on their location and role.In most parts of Baringo County, charcoal is produced from the invasive species Prosopis juliflora (mathenge, also known in some countries as ‘mesquite’).Community members, stakeholders and county officials identified priorities for the production and governance of the mathenge charcoal value chain.Strategies include proper management of biomass, efficient processing and effective utilization, and adequately regulated and supported value chains from production to consumption.Good governance of woodfuel value chains will only be achieved when there are transparent, consistent and coordinated regulatory institutional mechanisms that support and incentivize compliance and penalize illegality along the whole value chain. The County Environment Committee initiated a governance process, whilst community members have been engaged in sustainable mathenge charcoal production in Marigat Sub-county.
