Towards a greener flight path

On a single busy day in the summer of 2007, 3.2 million people took to the skies above Europe in 33,000 flights which covered a total distance of 34 million km. That’s 42 billion passenger kilometres generated in just one day of European air traffic movements.

Impressive though these numbers appear, they are in fact expected to double shortly after 2025, assuming that the demand forecasts hold true and that the capacity issues across the European air traffic system are solved.

Voulez-vous un vélo?

If CO2 emissions from transport cause climate change, why not encourage more cycling? This is precisely what places like Brussels, Copenhagen, Vienna and Berlin are starting to do. One much talked about initiative is in Paris. As the home of cycling’s greatest race, the Tour de France, you would be forgiven for thinking the French always loved cycling. Yet until last year, cyclists and bicycle lanes were a rarity in the capital.

Aviation: Responsible growth for a global industry

With aviation growing in terms of the number of planes operating and passengers taking to the skies, the industry is engaged in an important and candid dialogue—how to continue to grow responsibly, while further reducing its impact on the global ecosystem

Ecodriving: More than a drop in the ocean?

The urgency of reducing fuel consumption rates while transport moves towards massive development over the next two decades, notably among developing economies, is clear. Any weapon counts as part of the overall package. Enter “ecodriving”.

Making cars cleaner

Would adding US$1,500 to the price of a new car be enough to help halt climate change? That’s what US and EU experts broadly agree on as the average price tag for new technologies coming on stream to make cars more fuel-efficient and climate friendly. But what does that price tag entail?

Biofuels

As the UN called recently on the world’s governments in an “extraordinary emergency appeal” for some $500 million to avert a food crisis in poor countries, many people were placing some share of the blame squarely on strong demand for grains from the biofuel industry.

Towards integrated policies

Transport is a major contributor to CO2 emissions. But can policymakers make a difference? We asked Anu Vehviläinen, Finland’s minister for transport, and chair of the first International Transport Forum in Leipzig in May 2008.

Solving transport's CO2 problem

Any serious attempt to deal with climate change must involve transport. Transport accounts for 13% of all world greenhouse gas (GHG) emissions, though this figure takes into account CO2 sources other than fuel combustion, such as forestry, land-use and biomass burning. A look at CO2 emissions from fuel combustion only shows the transport sector accounts for about 23% worldwide and about 30% in the OECD area.

Tackling climate change

A 50% rise in global greenhouse gas emissions by 2050, higher temperatures, with more droughts and storms harming people, crops and buildings; more animal and plant species becoming extinct under expanding farmland and urban sprawl; dwindling natural resources; a billion more people living in water-stressed areas by 2030, with more pollution, disease and premature deaths ahead.

#23 Frankie in the dark
In Bali

Secretary-General Angel Gurría led a high-level mission of OECD economists and environmental experts at the UN Climate Change Conference in Bali in December. In this extract from one of his interventions at the conference, Mr Gurría explains some of the reasons why economics and markets must be at the heart of any effective and equitable strategy to tackle climate change.

Uncertain climate

The UN Climate Change Conference in Bali in early December 2007 may have raised new hopes of progress, but as everyone knows, dealing with climate change will require more than just political goodwill. Providing for abundant, affordable, clean energy will require considerable investment in new power generation–more than US$11 trillion to 2030, based on an estimate in the IEA’s World Energy Outlook 2006.

The Bali road map

The United Nations Framework Convention on Climate Change Conference in Bali in December 2007 was high in political stakes as well as emotion. But did it produce a result and what more might be done? New Zealand’s climate change ambassador offers his views.

Climate change special

Welcome to this special online focus on climate change, in view of the UN Climate Change Conference in Bali, Indonesia, 3-14 in December. "Ambitious policies to tackle climate change should lead to a structural shift in the economy – away from carbon-intensive activities. So the question that remains is: how can this transition be managed in an economically efficient and socially responsible manner? We should not exaggerate the cost of change. Action is affordable."

Climate change: Affordable action now

Energy consumption, and in particular the burning of fossil fuels, is the main source of human-induced greenhouse gas emissions. But energy is also a fuel for economic growth, particularly in the fast developing economies of the world. The challenge is to maintain economic growth, while reducing the carbon-content of energy and increasing the efficiency of its use.

Market power: Can Clean Development Mechanisms work?

Market-based credits can help control emissions alongside other instruments, though the system needs more work. And time. 

Eco-innovation, policy and globalisation: Making a world of difference

Investment in clean technologies can help achieve a wide range of environmental objectives, from mitigating climate change, to controlling air and water pollution, and enhancing resource efficiency in general. Indeed, many governments now see technological innovation as a key channel through which they can lift their economies onto a more sustainable path. But what role can public policies play in encouraging such innovation?

Beyond sun roofs

Prof Vaclav Smil's lucid and measured thinking is correct in that we must be realistic about renewable energy's future (No 258/259, December 2006). But I wonder if he is not being too dismissive of solar energy.

Environmental satellites

Satellites are not just about communications or defence, but can help us understand if not resolve some difficult environmental challenges, including climate change. They are investments in innovation whose benefits for humanity should speak for themselves.

Cotis leads top French bureau–
Jean-Philippe Cotis, the OECD’s chief economist, has been appointed as director general of the French national statistics institute INSEE (Institut national de la statistique et des études économiques, or the National Statistics and Economic Studies Institute).

Innovation, globalisation and the environment

Globalisation is exerting pressure on the environment, but it may also provide solutions. Could green be turned to gold? Climate change, melting polar ice, rising sea-levels, unpredictable weather patterns, drought, rampant urbanisation, demographic explosions: the list goes on. Many people blame globalisation for these ills, and it is true to say that increased economic pressures inevitably leave a bigger footprint on our planet.

Renewable promise

Can our insatiable appetite for energy be met efficiently and cleanly by renewable sources?

Coal faces the future

In OECD countries coal has a blackened image. Yet, it remains a key component of any energy mix. Innovation might help make that future brighter.

Oil change

Fighting global warming means reducing dependency on oil. But though supply is insecure, it remains plentiful. Keeping oil in the energy mix makes sense.

Can taxes on energy work?

Can taxation help governments achieve environmental goals with respect to energy use and emissions? Yes, with conditions.

Energy: Finding a new gear

Global warming, finite fossil fuels and geopolitical risks make a shift to renewable energies inevitable. Though it is a challenge fraught with uncertainties, no action would be worse. An alternative, workable energy strategy is within reach.

Fuelling emissions

Transport is the main cause of carbon dioxide emissions, ahead of power generation or industry. While aviation accounts for 14% of transport-based CO2 emissions in the EU, roads have a larger effect. In OECD countries, road transport accounts for over 80% of all transport-related energy consumption, for most of the accidents and the majority of air pollutant emissions, noise and habitat degradation.

21st century energy: Some sobering thoughts

Transition to new energy sources is unavoidable, but here are five sobering first principles to remember along the way.

Energising change

Energy has moved to the top of our policy agendas, and with good reason. First, there is the price of oil, which though easing a little in recent months, remains historically high. This has pushed up costs for producers and consumers alike.

Nuclear energy: Towards sustainable development

OECD countries share the same goals of sustainable development, but differ in their views on the role of nuclear energy in achieving those goals. Indeed, few energy sources have been scrutinised in the public spotlight over the years quite as much. The question is simple: is nuclear really a sustainable energy?
