The new Agenda for Sustainable Development, which aims to end poverty and promote well-being and prosperity while safeguarding ecological systems of the planet by 2030, has placed a much-needed emphasis on energy access and gender equality, elevating them as stand-alone sustainable development goals (SDGs). Similarly, there is now an increasing appreciation in international development discourses of the role of energy as a conduit for redressing historic gender inequities. Yet, energy poverty is still pervasive – one in five people in Africa and South Asia do not have access to electricity, and close to 3 billion people (40 percent of the global population) burn solid fuels such as wood, charcoal, animal waste or crop residues in open fires or inefficient stoves for their daily cooking and heating. As we transition into the 2030 development agenda, serious effort is needed to move beyond understanding the importance of both energy access and gender equality to viewing both as central to questions of sustainability, efficiency and effectiveness in the energy sector.
After decades of regulation and investment to reduce point source water pollution, OECD countries still face water quality challenges (e.g. eutrophication) from diffuse agricultural and urban sources of pollution, i.e. pollution from surface runoff, soil filtration and atmospheric deposition. The relative lack of progress reflects the complexities of controlling multiple pollutants from multiple sources, their high spatial and temporal variability, the associated transactions costs, and limited political acceptability of regulatory measures.
The OECD report Diffuse Pollution, Degraded Waters: Emerging Policy Solutions (OECD, 2017) outlines the water quality challenges facing OECD countries today. It presents a range of policy instruments and innovative case studies of diffuse pollution control and concludes with an integrated policy framework to tackle this challenge. An optimal approach will likely entail a mix of policy interventions reflecting the basic OECD principles of water quality management – pollution prevention, treatment at source, the polluter pays and the beneficiary pays principles, equity, and policy coherence.
Global Trends in Renewable Energy Investment 2017, published on April 6th by UN Environment, the Frankfurt School-UNEP Collaborating Centre, and Bloomberg New Energy Finance, finds that all investments in renewables totalled $241.6 billion (excluding large hydro). These investments added 138.5 gigawatts to global power capacity in 2016, up 9 percent from the 127.5 gigawatts added the year before.
Investment in renewables capacity was roughly double that in fossil fuel generation; the corresponding new capacity from renewables was equivalent to 55 percent of all new power, the highest to date. The proportion of electricity coming from renewables excluding large hydro rose from 10.3 per cent to 11.3 per cent. This prevented the emission of an estimated 1.7 gigatonnes of carbon dioxide.
Transforming the linear economy, which has remained the dominant model since the onset of the Industrial Revolution, into a circular one is by no means an easy task. Such a radical change entails a major transformation of our current production and consumption patterns, which in turn will have a significant impact on the economy, the environment and society. Understanding these impacts is crucial for researchers as well as for policy-makers engaged in designing future policies in the field. This requires developing an in-depth knowledge of the concept of the circular economy, its processes and their expected effects on sectors and value chains. This paper reviews the growing literature on the circular economy with the aim of improving our understanding of the concept as well as its various dimensions and expected impacts. On the basis of this review, it attempts to map the processes involved and their application in different sectors. The paper suggests that research on the circular economy is currently fragmented across various disciplines and there are often different perspectives and interpretations of the concept and the related aspects that need to be assessed.
During the past few years, the term “Blue Economy” or “Blue Growth” has surged into common policy usage, all over the world. For some, Blue Economy means the use of the sea and its resources for sustainable economic development. For others, it simply refers to any economic activity in the maritime sector, whether sustainable or not.
Despite increasing high-level adoption of the Blue Economy as a concept and as a goal of policy making and investment, there is still no widely accepted definition of the term. To fill this gap in shared understanding about what characterises a sustainable Blue Economy, and to help ensure that the economic development of the ocean contributes to true prosperity, today and long into the future, WWF has developed a set of principles.
