"Back to the Future" festivities marking 21 October 2015 as the date Marty and Doc travel to the future in the famous film with Michael J. Fox. If only we had a similar time machine allowing us to travel to 2045 to see what the climate has in store to better decide what policies to adopt today. Alas, no time machine has been invented yet but, in the absence of such a cool device, we can rely on climate and economic models...

How have CO2 and greenhouse gas (GHG) emissions changed since 1990? Three different visuals tell three very different stories (click on them to see full size). Which perspective offers the most clarity?

This project is unique in that it explores how national-level policies impact household behaviour. Topics include energy use, food consumption, personal transport choices, waste generation and recycling, and water consumption. Yet the project does not specifically discuss the term “ecological footprint,” and it retains a macro-policy focus, targeting governments interested in learning which policies to implement.

Given the years of preparation – and for some OECD colleagues, a life’s work – my hope was for an enduring, ambitious text, helping us to avoid climate catastrophe. My expectation was far less grand, more closely aligned to the reality of getting 195 countries to adopt an agreement with legal force.

Paris is a beautiful city but has an ugly problem with air pollution. Using 2 wheels to get to work, one becomes acutely aware of this insidious addiction to cars, and the “essence” of the problem, DIESEL.

“If He holds back the waters, there is drought; if He lets them loose, they devastate the land”. To be fair, that was in the days before governments played “a key role in developing targeted policy responses to market failures that impede the mitigation and allocation of drought and flood risks”, as the OECD report on Mitigating Droughts and Floods in Agriculture puts it.

The consequences of degradation of environmental quality as well as the consequences of environmental policies are typically unevenly distributed. In general, poorer countries and lower income households are more severely affected by environmental degradation and at the same time have less capacity to adapt.

A dirty, rundown environment has quantifiable costs for the economy and the well-being of societies. For example, the welfare costs of air pollution from road transport alone are estimated to amount to around 1.7 trillion USD in OECD countries, 1.4 trillion USD in China and 0.5 trillion in India.

Clearly a revolution in the global economy is needed for a heavy reduction of GHG emissions. You may have heard of Carbon Capture and Storage or CCS. This technology prevents CO2 from fossil fuel combustion from accumulating in the atmosphere.

The initials ‘CCS’ usually stand for Carbon Capture and Storage. However, I was with the team in Paris during COP21 promoting the Cap Global Carbon proposal; the mechanism embodied in Cap Global Carbon is Cap & Share, and it occurred to us that the name ‘Carbon Cap & Share’ has the same initials, CCS. Are these two types of CCS complementary or antagonistic? Are they friends or enemies?

A stern warning for climate change, and our health - Shipping brings us 90% of world trade and has increased in size by 400% in the last 45 years. Cargo ships, tankers and dry-bulk tankers are an essential element of a globalised world economy, but they are thirsty titans and they won’t settle for diet drinks. There are up to 100,000 working vessels on the ocean and some travel an incredible 2/3 of the distance to the moon in one year.

The theme of Biodiversity Day this year is “Mainstreaming biodiversity; sustaining people and their livelihoods”. According to World Bank figures, “natural capital accounts for an estimated 30% of total wealth in low income countries compared to only 2% in OECD countries”.

Climate change is not just about a change in climate towards hotter, wetter, and drier conditions, but also about an increase in the variability of the climate, as well as in the number and severity of extreme events.

“National governments must take the lead and do so with a recognition that they are part of a global effort.” Speaking last week at the Munk School of Global Affairs in Toronto, OECD Secretary-General Angel Gurría urged countries not to retreat behind their national borders in dealing with climate change.

This paper details a methodology for calculating the extent of terrestrial and marine protected areas recorded in the World Database on Protected Areas by country, type and IUCN management categories. The method allows the data on protected areas to be summarised in a harmonised and more detailed way than is currently available, without requiring any additional reporting by countries.

Infrastructure resilience requires a coordinated policy response to ensure that infrastructure owners and developers have the incentive and capacity to integrate resilience. The framework is aimed at policy makers in OECD countries, but the underlying messages can be applied to other country contexts.

The wet and verdant expanse of the Mekong Delta’s rivers and farms is a veritable rice bowl for the world. Not only do the region’s paddies produce half of Viet Nam’s rice crop yearly, the country is the world’s third largest rice exporter, with 17% of world exports of paddy rice. Our analysis identifies Viet Nam as facing the world’s fourth highest water risks for rice production.

“We are launching the “Paris Collaborative on Green Budgeting” within the framework of our zero-emission objective,” French president Emmanuel Macron said at the global climate financing summit. The OECD has brought together a cross-disciplinary group of environmental, tax, budget and fiscal affairs experts who will partner with countries to help them assess and improve their budgets and fiscal policies for climate resilience.

We are losing diversity of life on Earth at an alarming rate – one tenth of the world’s terrestrial biodiversity and one third of freshwater biodiversity has been wiped out since 1970. And we’re on course to lose another 10% of terrestrial species by 2050.

Cities with highest average population densities in the world are facing the challenge of urban sprawl. Finding sustainable solutions to reduce sprawl demands rethinking urban space and weighing the private benefits of low density living–my house and garden–against social, environmental and infrastructure costs.

17-22 November 2018, Sharm El-Sheikh, Egypt. The OECD actively participated in this Conference through an official OECD side event and by taking part in a number of workshops, seminars and other events throughout the conference. Read more on the OECD side-event, participation at the High-Level Segment and the OECD work on biodiversity.

Agriculture production is highly dependent on water and increasingly subject to water risks; and is the largest using sector and a major polluter of water. Improving agriculture’s water management is essential to a sustainable and productive agro-food sector.

Embracing new technologies that could enable drastic reductions in GHG emissions will be key to delivering low-emissions pathways for growth, but it is not always obvious what the big breakthroughs will look like. This report looks at how blockchain technology can be applied to support sustainable infrastructure investment that is aligned with climate change objectives.

Developing countries are at the forefront of the ongoing battle to address climate change. Roughly 60% of the new infrastructure built before 2030 will be in the developing world, and it is these investment decisions that will determine our collective ability to address the climate emergency.

A new OECD report presents around 550 measures that support fossil-fuel production or use in the OECD’s 34 member countries and also highlights the successes and challenges in bringing about reform, says this OECD Insights blog post.

As discussions to develop a set of sustainable development goals (SDGs) build momentum, attention is starting to shift towards not only what the world should try to achieve, but also how to go about it.

The rapid pace of development in many developing countries raises the stakes for investments in development, but also begs reflection on the patterns or types of growth that are appropriate for a particular country context.

Health is both a precondition for, and an outcome of, sustainable development. Climate change affects health through a myriad of exposure pathways, each presenting simultaneously both challenges and opportunities for sustainable health and development.

This book discusses scientific and technological tools at the centre of a renewed interest in marine biotechnology that is contributing to a new bioeconomy sector in many countries and offering potential new solutions to global challenges.

The report presents the potential of new nanomaterials and highlights the remaining challenges for their safe and sustainable introduction in the tyre industry.

Let’s be honest, waste reduction doesn’t have much of a ring to it. To many, it’s a complex policy issue without much hope if consumers keep throwing their cans away in the street.

The Green Growth and Sustainable development Forum is an annual event, and the third Forum will take place on 13-14 November 2014. This blog highlights the importance of the Forum, and how, far from being "abstract", this year's Forum offers an invaluable opportunity to address the social implications of implementing green growth strategies.

This will be “the mother of all years for summits on international development". International delegates will gather in Addis Ababa in July to discuss how poorer countries can fund their development. In September, attention will shift to New York, where the UN will sign off on the successors to the Millennium Development Goals (MDGs). In December, Paris will take centre stage to host the global climate change conference, COP21.

Ever plodded through flood waters to get to a conference? In late January, the Green Growth Knowledge Platform (GGKP) held their 3rd annual conference in Venice, Italy. The flooded city reminded attendees about the real world changes that are occurring and the need for continued action towards going green.

A new OECD publication highlights notable economic and environmental benefits of phasing out fossil-fuel subsidies in Indonesia. Interestingly, the study is based on the context that pertained until mid-2014, when international oil prices where high and before the recent phase-out of subsidies by the government.

To mark the opening of the International Transport Forum’s Annual Summit, today’s post addresses three broad issues of the complex and multidimensional triangular relationship between transport, trade and tourism.

With the world welcoming the new comprehensive global climate agreement at COP21 aiming to limit the global average temperature rise to well below 2 degrees Celsius, it is worth noting the significant contribution that the OECD family has made. These contributions were aptly summarized in a useful joint statement by the secretariats of OECD, IEA, International Transport Forum and Nuclear Energy Agency right after COP21 kicked off.

As part of the Better Life Index, Sustainable Development forms a multi-faceted key role in the way the OECD carries out its policy analysis. This latest blog from the OECD's Chief Statistician outlines how this is done.

The OECD defines policy coherence for sustainable development (PCSD) as an approach and policy tool to integrate the economic, social, environmental, and governance dimensions of sustainable development at all stages of domestic and international policy making. This blog details the OECD's PCSD framework and its goals.

The Sustainable Development Goals which world leaders agreed on in 2015 are focussed on people, peace and planet.
