#1 NEW YORK TIMES BEST SELLER • In this urgent, authoritative book, Bill Gates sets out a wide-ranging, practical—and accessible—plan for how the world can get to zero greenhouse gas emissions in time to avoid a climate catastrophe. Bill Gates has spent a decade investigating the causes and effects of climate change. With the help of experts in the fields of physics, chemistry, biology, engineering, political science, and finance, he has focused on what must be done in order to stop the planet's slide to certain environmental disaster. In this book, he not only explains why we need to work toward net-zero emissions of greenhouse gases, but also details what we need to do to achieve this profoundly important goal. He gives us a clear-eyed description of the challenges we face. Drawing on his understanding of innovation and what it takes to get new ideas into the market, he describes the areas in which technology is already helping to reduce emissions, where and how the current technology can be made to function more effectively, where breakthrough technologies are needed, and who is working on these essential innovations. Finally, he lays out a concrete, practical plan for achieving the goal of zero emissions—suggesting not only policies that governments should adopt, but what we as individuals can do to keep our government, our employers, and ourselves accountable in this crucial enterprise. As Bill Gates makes clear, achieving zero emissions will not be simple or easy to do, but if we follow the plan he sets out here, it is a goal firmly within our reach.

This publication highlights the use of wood for energy and includes the most recent statistics on wood energy markets across the UNECE region. It aims to communicate the relevance of wood energy in the region and help bridge information about the forest and energy sectors. It also intends to offer some of the best-available information on the role that wood energy can play in various sectors to support environmental, energy, and socio-economic strategies toward a greener economy. It focuses on commercial wood energy uses in the UNECE including energy generated for cooking, heating and electricity generation.

Biochar is the carbon-rich product which occurs when biomass (such as wood, manure or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its persistence in soil and nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with potentially major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process. The first edition of this book, published in 2009, was the definitive work reviewing the expanding research literature on this topic. Since then, the rate of research activity has increased at least ten-fold, and biochar products are now commercially available as soil amendments. This second edition includes not only substantially updated chapters, but also additional chapters: on environmental risk assessment; on new uses of biochar in composting and potting mixes; a new and controversial field of studying the effects of biochar on soil carbon cycles; on traditional use with very recent discoveries that biochar was used not only in the Amazon but also in Africa and Asia; on changes in water availability and soil water dynamics; and on sustainability and certification. The book therefore continues to represent the most comprehensive compilation of current knowledge on all aspects of biochar.

Analysing the interaction between energy and climate change mitigation issues requires the adoption of a long-term perspective - looking up to fifty years ahead. The future cannot be predicted, particularly over longer periods. However, strategic planning and political decisions demand that we explore options for the future - and these are best developed through scenarios (conjectures as to what might happen in the future based on our past and present experience of the world and on plausible speculation about how these trends may further evolve). This volume looks at different types of scenarios, evaluating how they can be used to analyse specific aspects of the interaction between energy and environment over the longer term. It examines "exploratory scenarios" (based on different expectations of technical and/or policy developments over the next 50 years) and "normative scenarios" (based on a set of desirable features or "norms" that the future world should possess). These long-term scenarios complement the IEA's World Energy Outlook, which presents a mid-term business-as-usual scenario with some variants.

As climate disruption intensifies the world over, Californians are finding solutions across a diversity of communities and landscapes. Though climate change is a global existential threat, we cannot wait for nation-states to solve the problem when there are actions we can take now to protect our own communities. In Climate Stewardship: Taking Collective Action to Protect California, readers are invited on a journey to discover that all life is interconnected and shaped by climate and to learn how communities can help tackle climate change. Climate Stewardship shares stories from everyday people and shows how their actions enhance the resilience of communities and ecosystems across ten distinct bioregions. Climate science that justifies these actions is woven throughout, making it easy to learn about Earth's complex systems. The authors interpret and communicate these stories in a way that is enjoyable, inspiring, and even amusing. California is uniquely positioned to develop and implement novel solutions to widespread climate challenges, owing to the state's remarkable biogeographic diversity and robust public science programs. Produced in collaboration with the UC California Naturalist Program, Climate Stewardship focuses on regenerative approaches to energy, agriculture, and land and water use across forested, agricultural, and urban landscapes. The authors' hopeful and encouraging tone aims to help readers develop a sense that they, too, can act now to make meaningful change in their communities.
