REN21 Renewables 2018 Global Status Report (GSR)

More renewables in the energy mix worldwide! Renewable power, in particular, continued to rapidly grow in the last year, and overall accounted for 70% of net additions to global power generating capacity in 2017. However, heating, cooling and transport fuel together account for about four fifths of global final energy demand; but they continue to lag far behind the power sector with view to more widespread implementation of renewables.

The 2018 GSR, as comprehensive annual overview of the state of renewable energy worldwide, is available here on the website of REN21 (Renewable Energy Policy Network for the 21st Century):

Renewables 2017 Global Status Report (GSR)

The 2017 edition of the REN21 Renewables Global Status Report, launched in June 2017 to provide a comprehensive annual overview of the state of renewable energy, reveals that 2016 was another extraordinary year for renewable energy.

As of 2015, renewable energy provided 19.3% of global final energy consumption, of which 9.1% were traditional biomass and 10.2% modern renewables.

In the power sector, solar photovoltaics (47% of newly installed renewable power capacity in 2016) and wind (34% of newly installed renewable power capacity) were the most dynamic areas. Overall, by end of 2016, renewables covered 24.5% of global electricity demand.

2016 was the third year in a row where decoupling of economic growth and energy-related CO2 emissions occurred.

Despite good performance of renewables and significant advancement in the global renewable energy transition, further and faster progress is required. Some areas:

  • Although achieved progress in adoption of renewable energy is highly remarkable, it is not fast enough to reach the Paris Agreement goals.
  • Deployment of renewables for heating and cooling remains strongly underdeveloped.
  • Community-based renewable energy initiatives, which hold potential to make a vital contribution to speed the energy transition, now face less favourable frameworks compared to some years ago in several countries, resulting in slower pace of growth. As a positive trend, community-based schemes diversify their market activities, for example to also include storage and demand-side management.

E-waste and GDP Closely Correlated – New publication

Assessment of WEEE (waste electrical and electronic equipment) generation against the gross domestic product (GDP) data from 50 countries of the pan-European region reveals a very high economic elasticity, indicating that WEEE and GDP are closely interlinked, regardless of the economic developmental stage of individual countries. In this context, GDP at purchasing power parity (GDP PPP) is a more meaningful measure.  In the pan-European region, an increase of 1000 international $ GDP PPP means an additional 0.5 kg WEEE is generated that requires management.

GTTN Call for Experts: Timber Tracking

Curbing illegal logging and timber trade – call for experts in timber tracking (from both supply & user side) to participate in working groups of the Global Timber Tracking Network (GTTN) to further operationalise and promote innovative timber tracking tools:

GTTN Call for Experts in Timber Tracking

The GTTN is comosing its working groups for the second phase, as described in the flyer (pdf):

The Global Timber Tracking Network – In Focus: Illegal Logging and the Associated Timber Trade

Illegal logging and the associated timber trade are a serious threat for precious timber species and for forests in general. It impacts environment (biodiversity loss, soil degradation, climate change) as well as economy (tax evasion, corruption, distortion of timber market).

Timber tracking systems do exist to check tree species and geographic origin of wood. The most common ones, however, can be manipulated as they are paper-based or via electronic tags. That’s why development of timber tracking systems based on characteristics inherent to the wood are essential.

The Global Timber Tracking Network (GTTN) brings together experts in timber identification tools (wood anatomy, stable isotopes and DNA analyses), policy and advocacy specialists to

(i) integrate, optimize and standardize methods,

(ii) develop a global database with reference data,

(iii) raise awareness and train researchers worldwide.

At the start of the second phase of the GTTN, the new IUFRO report “Illegal Logging and Related Timber Trade – Dimensions, Drivers, Impacts and Responses” offers a welcome perspective on the problem of illegal logging and related timber trade. The full report is available via the IUFRO website. Key issues are highlighted by Dr. Nele Schmitz (GTTN; Thünen Institute of Forest Genetics) in her summary of the report:

Pursuit of Sustainability – From Knowledge to Action

The pursuit of sustainability requires more and better knowledge, but it is how knowledge is used that matters most. It is part of knowledge that social-environmental systems are influenced by interacting production and consumption processes. Understanding the dynamics of systems and how they can be influenced remains a key challenge. How can existing governance processes be reshaped so that they are more conductive to achieving social wellbeing? How can knowledge be linked with action?

Co-evolution of Technology, Society and Institutions: Science-Policy Interface Key for 2030 Agenda

The Global Sustainable Development Report (GSDR) 2016, issued in July by the UN Department of Economic and Social Affairs, points out that implementation of the 2030 Agenda for Sustainable Development requires asking new types of questions along the guiding principle of ensuring that no one is left behind. Strengthening the bridge between science and policies is identified as a need and key opportunity.

A nexus approach, looking at the interlinkages between infrastructure, inequality and resilience, reveals that harnessing synergies and addressing trade-offs is critical for policy-making. Processes must be supported by scientific knowledge and cross- and transdisciplinary collaboration. A critical function of the science-policy interface is to bring new and emerging issues to the attention of policy-makers. Identified issues are explored and focused, possibly leading to more timely responses to emerging threats or the exploitation of new opportunities.

As highlighted in the report, design and functioning of inclusive institutions is essential for delivering on the imperative to leave no one behind. Technology has greatly shaped society, economy and environment and vice versa. In achieving the SDGs, technology has a major role to play. One critical point is to take into account how technology, society and institutions co-evolve.

Environment in Europe: UNEP’s GEO-6 Assessment for the pan-European Region

As part of the Sixth Global Environment Outlook (GEO-6), a separate assessment for the pan-European region was launched in June 2016 at the 8th Environment for Europe Conference in Batumi, Georgia. The “GEO-6 Assessment for the pan-European region” provides a comprehensive picture of the current state, trends and an outlook for the environment in the region, and highlights factors that influence prosperity, human health and wellbeing. Focused under the lens of the 2030 Agenda for Sustainable Development (2030 Agenda), the report demonstrates that the challenges, but also the solutions, today are highly interlinked and more systemic.

“Clean air, water, resilient ecosystems and sound management of chemicals and waste are essential for a healthy planet and healthy people. Closing resource-use loops through the promotion of circular economy principles will be a necessary part of the solution, providing much-needed jobs and economic sustainability. The transition towards an inclusive green economy in the pan-European region presents a significant opportunity, which will require the active engagement of a “coalition of the willing” at all levels of society. It demands a fundamental redesign of energy, food, mobility and urban systems, as well as a change in lifestyles. Countries in the region have much to contribute to the shaping of a shared vision of the future.” (Foreword UNEP Executive Director, Achim Steiner, to the GEO-6 Assessment for the pan-European region)

Improving Energy Efficiency: Co-generation Revisited

Although combined heat and power production is already relatively common in Europe, its vast potential to improve energy efficiency is still heavily underexploited. Cleaner production schemes offer suitable frameworks to foster uptake of combined heat and power production by industry. Read more:
