In my first climate change lecture, nearly two years ago, my key message was that meeting the challenge of climate change required us to achieve zero net greenhouse emissions globally by the end of this century.
The climate is changing–not for the better, but for good. Governments want to limit the global temperature increase to less than 2⁰C, which implies that greenhouse gases (GHG) pumped into the atmosphere by human activity need to decline to around zero or below on a net basis towards the end of this century. GHG emissions in 2050 consistent with this target would be around 40% to 70% lower globally than in 2010. The world’s largest emitters have signalled their willingness to undertake strong collective action. The joint declaration between the US and China signed in Beijing in November 2014 has injected political momentum into the longer range effort to transform to low-emission-resilient economies. The US will cut its emissions from 2005 levels by up to 28% by 2025, while China said its emissions would peak around 2030.
But, critical as these shifts are, they are not enough to lower emissions in time. To do that, we will need to confront a logic even more entrenched than free trade—the logic of indiscriminate economic growth. This idea has understandably inspired a good deal of resistance among more liberal climate watchers, who insist that the task is merely to paint our current growth-based economic model green, so it's worth examining the numbers behind the claim.
It is widely accepted nowadays that climate change affects water supply. After all, it plays havoc with rainy seasons, melts glaciers, and causes drought in normally humid regions.
It’s easy to dream about holidays in far-off exotic islands, especially with current global petrol prices. A sustained low oil price has allowed many of us to put away a little more of that paycheck and think seriously about buying an iWatch or taking that much-deserved break.
The world is still not moving fast enough to fight climate change. Fossils fuels remain the dominant energy source with billions of dollars still being spent on subsidising their use.
In the transition to cleaner and greener economies, the OECD is helping government and business with the tools to get climate finance right for greener growth plus job creation, while treating our environment as a precious resource. See our last video on financing action on climate change.
The total number of deaths attributed to airborne pollution continues to decrease across the OECD world, largely thanks to regulatory policies for transport vehicle emissions and technological improvements. Between 2005 and 2010, pollution-related mortalities fell by 4% from approximately 498,000 cases a year, to just over 478,000. But a closer look reveals a more worrying picture. Outside of the EU, only the US and Israel have successfully attained reductions in deaths, while 14 other member countries–including Australia, Canada and Japan–actually recorded an increase in the absolute number of mortalities.
The River Seine overflowing its banks is not an uncommon sight in Paris, as the winter catchment swells, causing water levels to rise and cover the lower banks, jetties and walkways.
Imagine a house that keeps itself warm in the wintertime. Think of the savings in terms of fuel bills and unfriendly emissions. Such houses in fact exist. Called “passive houses”, the concept of these highly energy-efficient buildings took root in the 1990s, before slowly consolidating as a niche construction concept in the 2000s. Are passive houses now actively moving into the mainstream as sustainable buildings?
The car industry has taken a dent since the recession started to bite in 2008, but even before then, new patterns were emerging that would reshape the sector for a long time to come.
Time for an energy [r]evolution
We can’t use terms like “inclusive” and “green” as window dressing for the pursuit of economic growth as an end in itself. According to Greenpeace International’s chief, Kumi Naidoo, a real and profound change in how we think about growth is needed–one that doesn’t let special interests get in the way of creating a just, fair and sustainable economy with clean energy for all.
Climate change won't wait
The European Union may be facing some difficult economic challenges, but that's no excuse for not acting now to create an economy based on resource efficiency and low-carbon development. The benefits are potentially enormous, including lower greenhouse gas emissions, more efficient use of energy and resources, and rising growth and innovation.
“We’re going to run out of water much much earlier than we’ll run out of oil,” warned Peter Brabeck-Letmathe, chairman of Nestlé, at the OECD Forum in May 2012.
Thomas Edison’s assertion that “genius is 1% inspiration, 99% perspiration” is particularly pertinent to the solar energy sector. This remarkable technology could hold answers to so many of the world’s energy challenges, but only at the cost of hard effort and investment. Solar Energy Perspectives, the first in-depth study dedicated to solar technology from the International Energy Agency (IEA), a sister organisation of the OECD, gives a comprehensive analysis of solar energy’s potential as well as the policies required to increase its capacity in the coming decades.
The continuity of our societies and the sustainability of our planet will necessarily depend on how we, as a collective, can devise the solutions to the paramount and multifaceted difficulties that have arisen from the changes wrought by the Industrial Revolution. In fact, if we are to successfully transform these challenges into opportunities, what we need is nothing short of another revolution. And in today’s revolution the bayonets, unquestionably, need to be green.
While the world focuses on the ongoing economic crisis, the challenge of climate change grows increasingly desperate. A number of lessons still have to be learned.
Economic growth over the past decades has led to improved quality of life, increased prosperity and longer, healthier lives in nearly all countries. Resource constraints are making us realise that to continue to enjoy these benefits we will have to change course towards more sustainable or greener growth.
The Earth is a unique, interconnected system that mankind has always tried to understand. Although there have been great discoveries made in science, there are many aspects of our planet that are beyond our understanding or control. However, there is one fact we know: we need to live in harmony with nature.
Managing risk could absorb more policy time around the world in the 21st century. How can policymakers be prepared?
New York is investing in a greener, cleaner future.
After environmental and economic turbulence, Canada’s fisheries are being reformed. The sector is now undergoing a renaissance, though challenges remain.
One area where governments have been looking to raise revenues is green taxes. And with good reason. Taxes can provide a clear incentive to reduce environmental damage. But while the number of environmentally-related taxes has actually been increasing in recent years, revenues from these taxes have been on a slight downward trend in relation to GDP. The decline in revenue partly reflects the drop in demand for fuel in response to recent high oil prices and other factors, which in turn has led to a reduction in total revenues from taxes on energy products.
WWF’s 2010 Living Planet Report demonstrates that we are currently using 50% more resources than the earth can provide. If we allow current trends to continue, by 2030 we will need two planets to support us. It’s clear that “business-as-usual” is not the pathway to a prosperous future.
World agriculture faces an enormous challenge over the next 40 years: to produce almost 50% more food up to 2030 and double production by 2050. With pressure from increasing urbanisation, industrialisation and climate change also rising, proper water management will be vital.
In the years ahead, the global food and agriculture system will have to provide sustainably for billions more people and meet greater demands on quality, affordability and availability. Farming will be competing with other sectors for land, water and investment, while climate change adds new pressures.
Ministers and stakeholders from OECD member countries and key emerging economies gather in Paris on 25-26 February to discuss how best to respond to the challenges. We asked ministers from five of them–Austria and New Zealand as co-chairs, Canada, Germany and Chile–and leading representatives from Concern Worldwide, the International Federation of Agricultural Producers, John Deere, and the World Trade Organization:
“What actions are you prioritising to prepare the food and agriculture system for the needs of a rapidly changing world?”
