Potential gains from improving energy efficiency are substantial — not only in terms of saving energy and combating climate change, but also in terms of contributing to an array of other co-benefits, including improving human health and creating jobs. We asked Tim Farrell, Senior Advisor at the Copenhagen Centre on Energy Efficiency, what works best when it comes to boosting energy efficiency. He stressed that targeted policy measures and sufficient resources to support implementation and compliance are among a number of critical ingredients for success.
Only a decade ago, biofuel production from plants was hailed as an ecological alternative to fossil fuels. Recently, it has come to be seen as competing with food production and not always an effective solution in reducing emissions of greenhouse gases or air pollutants. We talked to Irini Maltsoglou, Natural Resources Officer at the Food and Agriculture Organization of the United Nations (FAO), about biofuel production and agriculture and if and how it can be done sustainably.
European countries consume less energy compared with 10 years ago, mainly due to energy efficiency gains. Europe also relies less on fossil fuels due to energy savings and the faster-than-expected uptake of renewable energy. In the decade 2005-2015, the share of renewables in the EU’s energy consumption nearly doubled, from 9 % to almost 17 %. Some sectors and countries are leading the way towards clean energy. Despite their declining share of the market, however, fossil fuels continue to be the dominant energy source in Europe.
Mitigating and adapting to climate change are key challenges of the 21st century. At the core of these challenges is the question of energy — more precisely, our overall energy consumption and our dependence on fossil fuels. To succeed in limiting global warming, the world urgently needs to use energy efficiently while embracing clean energy sources to make things move, heat up and cool down. The European Union policies play an important role in facilitating this energy transition.
Our quality of life depends, among other things, on a reliable supply of energy at an affordable price. We use energy to heat and cool our homes, to cook and preserve our food, to travel and to build schools, hospitals and roads. We use machines to carry out numerous tasks, contributing to our wealth and wellbeing, and machines need energy. We still burn fossil fuels to obtain most of the energy we use. Moreover, we waste a substantial part of this energy before and during use.
Exposure to harmful chemicals is known to have impacts on human health and the environment. With global chemical production on the rise and new chemicals being developed and put to use, how do we know what is considered safe? We discussed with Xenia Trier, EEA expert on chemicals, different issues linked to a safe use of chemicals in Europe and what the EU is doing to reduce their potential side effects.
To most people the idea of a circular economy remains an abstract if not far-off concept. While ‘going green’ is a growing popular theme around the world, many people are not yet aware of the greater changes to our way of living that will have to be made to ensure a sustainable future, and secure our long-term well-being.
In April, the European Environment Agency will help raise awareness of the growing problem of noise pollution across Europe. We discussed with Colin Nugent, an EEA noise pollution expert, the very real health impacts of noise which are often underestimated.
At all governance levels, public policy making entails making decisions between different options and approaches. Some decisions, such as to invest in fossil fuels or renewables, might involve selecting one option over the other. Others might address the ‘how’ question – we will invest in renewables but which ones are the best for the society? Each policy decision results in outcomes, some of which might be unforeseen, unexpected or even detrimental to those whose lives it is supposed to improve. In the long term, the overall harm can be much larger than gains in the short term. To achieve the positive and lasting results on the ground, policy makers need to be able to make informed decisions, after assessing the benefits and costs of each available option.
Our climate is changing. We must reduce greenhouse gas emissions to limit the rate of climate change, and at the same time, take measures that help us prepare for current and future impacts. Both of these strands of action require unprecedented redirection of investments. This was acknowledged by the climate conferences in Paris and recently in Marrakesh. The finance sector can and will play an instrumental role in supporting Europe’s transition towards a low- carbon, climate-resilient society.
Last month the European Environment Agency (EEA) released its latest ‘Air quality in Europe’ report which showed that while air quality is slowly improving, air pollution remains the single largest environmental health hazard in Europe. We sat down with Alberto González Ortiz, an EEA air quality expert, to discuss the report’s findings and how technologies like satellite imagery are helping to improve air quality research.
Last December in Paris, the world set itself an ambitious target: limiting the global average temperature rise well below 2 degrees, while aiming to limit the increase to 1.5 degrees above pre-industrial levels. At the G20 summit earlier this month, China and the United States announced their formal commitment to join the Paris agreement. This is a major step forward for the international effort to cut greenhouse gas emissions and limit global warming. Nevertheless, the current reduction commitments made so far by signatory countries are not sufficient to meet this ambitious target.
Modern society depends on the movement of goods and people, but our current transport systems have negative impacts on human health and the environment. We spoke to Magdalena Jóźwicka, project manager of an upcoming report on electric vehicles, about the environmental advantages and challenges of using electricity as an alternative to conventional fuels for vehicles.
From walking and electric cars to massive freight vessels and high speed trains, a wide range of transport options exist. Many factors, including price, distance, availability of infrastructure and convenience, can play a role when selecting a transport mode. Car rides are the preferred mode for passenger transport in Europe. But even then, some options are cleaner than others. How can we opt for greener choices?
Transport networks have become a commonplace feature of the European landscape. They connect people, boost economic activity and provide access to key services, but they also introduce barriers between natural areas, while their use emits pollutants and introduces non-local species to ecosystems. Strong policy measures and a network of green spaces can help preserve and protect Europe’s natural wealth.
Ingredients for the meals we eat at home or in restaurants come from near and afar. In an increasingly urbanised and globalised world, the food produced in the countryside needs to be transported to the city. Much focus has been put on reducing ‘food miles’, which can be a relevant but sometimes limited concept. A smarter and cleaner transport system would solve only part of the issue. A wider systemic analysis of the entire food system is in order.
Our cities are under pressure like never before from increasing populations, traffic gridlock and climate change. How can we make them easier to get around, more liveable and sustainable? One urban design firm is helping transform the way we plan cities. We talked to Helle Søholt, founding partner and CEO of Gehl Architects, Copenhagen, to find out.
Despite temporary slowdowns, the demand for transport of both passengers and goods has been growing steadily and is projected to continue. As such, more and more cars are sold in Europe, the majority of which are diesel powered. And while engines are becoming more efficient, this growth means GHG emissions are a major concern.
Flying off for a weekend break, cotton t-shirts made in Bangladesh, roses from Kenya… These are some of the products available to us in a well-connected, globalised world. Aviation and shipping contribute to economic growth, but they also lead to impacts on human health, the climate and the environment. Faced with future projections of growth, these two sectors have started to explore ways to reduce their impact.
Air and noise pollution from transport cause a wide range of health problems, with road transport and diesel vehicles in particular the biggest contributors. The European Union and its Member States are taking a series of measures to reduce the impact of transport on health with some success. Innovative solutions and local action can improve the situation further.
