Transport accounts for 23% of global CO2 emissions from fossil fuels, making it the second-largest emitter after electricity and heat generation (42%). Transport CO2 emissions have increased by 57% between 1990 and 2012, and the sector has lagged behind in decarbonising. In the EU, transport CO2 emissions increased by 36% from 1990-2007, while other major sectors reduced theirs by about 15%. Recent decreases in transport CO2 emissions had more to do with the economic crisis, rather than a shift to greener forms of transport.

The UN Conference on Climate Change in Paris in November-December is the final crucial step in a year which has set forth several global milestones towards shaping a better common future. Tackling climate change is a determining factor in the 17 Sustainable Development Goals (SDGs) agreed in New York in September 2015 in particular; an agreement in Paris would not only bolster all the efforts that led to the historic SDGs, but lift the hopes of everyone on the planet, especially the most vulnerable.

The human economy is a physical system embedded in society, which itself is embedded in a finite global ecosystem. The primary goal of the economy should be to meet basic human and social needs, now and in the future, without degrading the global ecosystem services upon which all life depends. How can this be done?

"We want to step out of the vicious circle of an economy which is an increasing drain on resources, and enter another circle… Paris is fully committed to combating climate change and determined to move forward as quickly as possible."  –Anne Hidalgo, Mayor of Paris 

An ecological transition has been necessary for many years. It has now become vital. Faced with the prospect of the total destruction of people and the environment, we must send out an equally uncompromising wake-up call on the ties that bind humans and nature.

Oil, gas and coal represent over 80% of energy use worldwide, and are a major cause of greenhouse gas emissions and other unhealthy pollutants. These fossil fuels also drive the likes of transport, industrial output, lighting, heating and construction, and naturally their use is heavily concentrated in urban areas. Roughly half the world’s population live in urban areas, and as towns and cities are an important generator of emissions, they must also play a key role in the fight against climate change.

Faced with heavy pollution and congested roads, Paris is turning to electric vehicles to restore air quality. Its incentive policies for all forms of transport should inspire cities all over the world to follow suit.

A residential site on the rue Saint Charles in the 15th arrondissement of Paris was the first retrofit under the Climate Plan led by the city’s property management agency, Régie Immobilière de la Ville de Paris (RIVP). The project proved complex but exemplary, not just in its implementation and execution, but also in terms of managing relationships.

Over the last century, resource extraction from non-renewable stocks has grown while extraction from renewable stocks has declined, reflecting the shift in the global economy base from agriculture to industry.

Near to the Paris ring road, shielded from the din of the motorway by an apartment block, nestled between two high-rises, lies an oasis of peace. It is a community garden created by Multi’Colors, and is just one of the many “urban sanctuaries” it has created in underprivileged neighbourhoods in and around the French capital.

Already a showcase when it was opened for the 1889 World’s Fair, the Eiffel Tower continues to light the way forward today, with sustainability being a feature on the monument’s new first floor unveiled in 2014.

Freshwater is essential for life, yet makes up only a tiny fraction of all water on earth. In many areas, especially arid and dry regions, underground aquifers are the only source. Even in less arid regions, groundwater provides an essential resource: in fact, some 2.6 billion people worldwide rely on groundwater resources. Farming is one major reason: over 60% of irrigated agriculture in the US uses groundwater, and in Spain more than 70% of irrigation comes from below ground reserves.    

How will workers’ current skills match new requirements for labour in a green economy? So far, few countries have put in place real plans to address this question, yet there is risk of a significant mismatch between skills and jobs. Would you know who to call if your geothermal system crashes? Should construction workers learn new skills for retrofitting buildings?

If the world is to make a dent on climate change, breaking the arm-lock of fossil fuels is inevitable. After all, limiting the rise in global temperatures to no more than 2°C by the end of the 21st century demands curbing greenhouse-gas emissions between 40% and 70% by 2050 compared with 2010 levels, which means replacing fossil fuels–coal, oil and gas–with low-carbon energy sources and developing technologies to capture and store CO2.

Carbon dioxide (CO2) emissions worldwide have been trending upwards for decades. A small group of large countries is responsible for the lion’s share of these global emissions.

In tackling climate change, it makes sense for policymakers to know which sectors greenhouse-gas emissions are coming from. Our chart shows the main sources for European carbon dioxide (CO2) emissions, including electricity supply, manufacturing, households and transportation. Household emissions are largely generated from fossil fuel energy used to heat dwellings, but some of the other industry sources are more complex.

A warming planet and a flat world economy have propelled the issue of investment in clean energy to the top of the policy agenda. The question has become all the more crucial in view of the landmark global summit on climate change to be held in Paris in December 2015. 

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. 

A transition to a low-carbon economy is achievable, but will require a concerted, more consistent effort across a range of policy areas, from tradeable permits to stringent norms.

Challenging free trade orthodoxy is a heavy lift in our political culture; anything that has been in place for that long takes on an air of inevitability. 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. 

The decisive UN climate summit Paris 2015 is approaching. Climate change risks disrupting our economies, our ecosystems and our lives. Everyone is concerned. World leaders and stakeholders meeting at the 21st UN climate summit (called COP21) in Paris from 30 November to 11 December 2015 must forge a new universal agreement to cut emissions and keep global warming at bay.

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.
