Management
Published in Wanda Grimsgaard, Design and Strategy, 2023
An increasing number of countries, organisations and businesses are committing to net zero emissions of greenhouse gases. ‘Some are even moving beyond this, committingto transition to decarbonised and carbon-negative economies’ (Design Council, 2022). In the report ‘The Net-zero Transition: What it would cost, what it could bring’ (2022), McKinsey look at what the economic transformation that a transition to net-zero emissions would entail. The study estimates the changes in demand, capital spending, costs, and jobs, to 2050, for sectors that produce about 85 percent of overall emissions and assess economic shifts for 69 countries. This report, as well as the McKinsey report ‘Net zero & ESG Strategy: Helping leaders and organizations rewrite the climate math equation’ (2021), will be of valuable help when recreating the business strategy.
Electrification and Targets in Developing Countries

Measuring progress on SDG7 should include looking beyond minimal energy access for basic household services to sufficient job creation and income generation levels. Developing countries need sufficient electricity to power businesses and grow their economies, but this electricity needs to come from low-carbon sources to achieve net-zero emissions by 2050 and deliver on development priorities.
Nuclear Renaissance
Published in William J. Nuttall, Nuclear Renaissance, 2022
Over the years the original call by the Royal Commission for Environmental Pollution for a 60% greenhouse gas emissions reduction by 2050 has been followed by ever-tightening requirements. In 2019, the UK government officially committed to the goal of achieving national Net Zero emissions by 2050 [61]. Such a goal pushes the national ambition far beyond electricity decarbonisation, fully bringing in heat and mobility. Furthermore, the requirement to achieve Net Zero forces change on the most difficult to decarbonise sectors and in this author’s opinion, it is this obligation that presents the greatest opportunities for nuclear technologies to make a material difference.
A complex balance: assessing perspectives on decommissioning large dams to restore river ecosystems
Published in Water International, 2023
Joshua Matanzima, Teboho Mosuoe-Tsietsi
Dams such as the Aswan High Dam in Egypt, the Akosombo Dam in Ghana, the Three Gorges Dam in China, the Chandil Dam in India, the Mangla Dam in Pakistan and the Hoover Dam in the United States are all examples of dams constructed for multipurposes, including irrigation, power generation and flood control. Considering the global demands for food security, energy (and, in particular, renewable energy), and the need to contain floods in the context of extreme weather conditions resulting from climate change, dams evidently have a critical role to play, not only in economic development but also in the survival of human beings. They can contribute to the achievement of net zero emissions targets that various countries have set in response to climate change, and prevent the flooding that threatens the lives and livelihoods of multitudes.
Carbon neutral industries and compensation for greenhouse gas emissions
Published in Drying Technology, 2022
Rubén D. Piacentini, Sofía Garro
An increasing number of industries and governments (international, national, regional and at city level) is establishing plans to arrive at a neutral carbon level in a reasonable timeframe. This implies implementing climate change strategies, measuring greenhouse gas (GHG) emissions, setting up reduction goals, implementing actions to reduce emissions, checking if the actions work as expected and correct them if not. An institution has arrived zero emissions condition if no emissions occur in all of its related activities, and consequently it is considered carbon neutral. The path to a net zero emissions scenario involves replacement of all types of fossil fuel consumption with renewable energy such as solar, wind, hydro power, geothermal and renewable fuels, such as bioethanol, biodiesel, biogas and hydrogen. It also means generation of zero emissions in waste disposal and implies zero emissions in the value chain of the company from suppliers to consumers. As this is very difficult to attain in practice, institutions aiming to become carbon neutral need to compensate for their unavoidable emissions. This path includes support of economic projects that result in absorption of the generated greenhouse gases. Some organizations go further and aim to become carbon negative, which means the activities of the organization absorb more greenhouse gases than what it produces. In some situations, organizations not only set future goals, but also compensate for their past emissions by becoming carbon neutral in its whole operation from past to present and even projecting to be carbon neutral in the future.
Toward comprehensive zero energy building definitions: a literature review and recommendations
Published in International Journal of Sustainable Energy, 2021
Javad Taherahmadi, Younes Noorollahi, Mostafa Panahi
Net-zero emissions: A net-zero emissions building produces at least as much emissions-free renewable energy as it uses from emissions-producing energy sources. Maybe it can be said, the two most common definitions in articles are ‘net-zero site energy’ and ‘net-zero source energy’. The meaning of Net-zero site energy is that annual energy production in the site and annual energy demand are similar, and these values are independent of energy production or utilisation. In the definition of ‘net-zero energy source,’ calculation for energy export and import is done by a primary energy conversion factor, which can be useful to create flexibility in the heating fuel usage. For instance, if the primary electricity factor is higher than other heating fuels factor and a building sells electricity to the utility companies, the allowed amount of heating fuel will be more significant because of its smaller primary energy factor.
