                Multiple Benefits of Energy Efficiency for Business The business value of energy efficiencyThe business value of energy efficiency

                Energy efficiency is often described as the “first fuel” because the cheapest and most secure energy is the energy that is not used. For businesses, this begins with a straightforward benefit: lower energy bills. In many cases, efficiency investments can pay back quickly through reduced energy costs alone, improving margins and reducing exposure to price volatility.However, the value of energy efficiency extends beyond energy savings. By improving how equipment, buildings and processes operate, efficiency measures deliver wide-ranging benefits that strengthen business competitiveness across several dimensions: Operational benefits Efficient and electrified equipment operates more reliably and with less stress…

                Outlook for Biogas and Biomethane Introduction to biogas and biomethaneIntroduction to biogas and biomethane

                Biogas is a mixture of methane, CO2 and small quantities of other gases produced by anaerobic digestion of organic matter in an oxygen-free environment. Its precise composition depends on the type of feedstock and the production pathway. The methane content of biogas typically ranges from 45% to 75% by volume. Biogas is usually produced using the following technologies: Biodigesters: These are airtight systems (e.g. containers or tanks) in which organic material is broken down by naturally occurring micro-organisms. Contaminants and moisture are usually removed before use of the biogas. Landfill gas recovery systems: The decomposition of municipal…

                Prospects for Natural Gas Certification Executive summaryExecutive summary

                Governments and industry are working to improve resource efficiency and reduce emissions from natural gas supply – from both domestic production and imports – to help deliver on their climate goals, while also looking to improve energy security. One emerging approach is natural gas certification, which can help buyers make more informed decisions by providing independently verified greenhouse gas (GHG) intensity data at select stages of the supply chain, from production and processing to storage and transport, but excluding final consumption. This can support the implementation of best practices throughout the entire supply chain, and help importing countries and regions better understand…
