Jerry Brown is the governor of California. He spoke ahead of the UN Secretary-General's Climate Leadership Summit about politics and the value of his state's emissions trading system in building a healthier, cleaner future. The state's economy is growing, and its climate work is setting a pace for the nation.

Carbon pricing – delivering economic & climate benefits

A dangerously warming planet is not just an environmental challenge – it is a fundamental threat to efforts to end poverty, and it threatens to put prosperity out of the reach of millions of people.  Read the recent Fifth Assessment Report from the Intergovernmental Panel on Climate Change if you need further evidence.

If we agree it is an economic problem, what do we do about it?  There is general agreement among economists that a robust price on carbon is a key part of effective strategies to avert dangerous climate change. A strong price signal directs finance away from fossil fuels and toward a suite of cleaner, more efficient alternatives.

This logic is not lost on governments and companies.  Momentum is building around the globe to put a price on carbon.  Consider these facts:

Carbon Partnership Facility: Innovation in Scaling-up Emission Reductions

We’re about 16 months away from the 2015 UN climate meeting in Paris, intended to reach an ambitious global agreement on climate change. Now, more than ever, there is a need for innovation to scale up climate action.

The Bank’s Carbon Partnership Facility (CPF) is helping blaze that trail.

The role of the CPF is to innovate in scaling up carbon crediting programs that promote sustainable, low-carbon economic growth in developing countries. In its first set of programs, the CPF moved past the project-by-project approach to larger scale through the Clean Development Mechanism’s Programme of Activities, catalyzing investment in methane capture from landfills, small-scale renewable energy, and energy efficiency.

Be the Movement: 14 Ways to Advance Climate Action

Max Thabiso Edkins's picture

For World Environment Day, Connect4Climate just released a new collection of ideas for invigorating climate action, drawn from the hundreds of you who attended our international workshop on climate action and from the leaders who inspire you.

Curbing climate change will take bold action – that's a given. What we wanted to learn from the Be the Movement workshop on the sidelines of UN climate talks in Warsaw was what we can all do to encourage bold action now.

Here’s a sneak peek at the outcome. You can read more in Knowledge4Climate Action, our new report on energizing the global movement for action to tackle climate change.

More than 500 participants identified and discussed five vital needs for the climate change movement: messaging for new audiences, empowering educators, innovating campaign strategies, considering costs, and leading for solutions. These 14 key recommendations emerged:

Carbon Bubbles & Stranded Assets

Packing an extraordinary amount of energy in little space, fossil fuels helped propel human development to levels undreamed of before the Industrial Revolution, from synthesizing fertilizers to powering space flight. But alongside energy, they produce health-damaging air pollutants and greenhouse gases.

Today, greenhouse gas emissions are higher than at any time in at least 800,000 years and rising, causing climate changes that threaten to reverse decades of development gains. Disruption of livelihoods, loss of food security, loss of marine and coastal ecosystems, breakdown of infrastructure, threats to global security: these are just a few of the risks identified in recent scientific reports.

In the absence of technology to permanently remove greenhouse gases and restore atmospheric concentration to safe levels, there is only one realistic solution: limiting additional emissions. It is estimated that to avoid the most damaging effects of climate change, over the next few decades we can at most emit a quantity equal to about 20 percent of total proven fossil fuel reserves.

Given fossil fuels’ omnipresence in our economies and lives, leaving them in the ground will have important implications, starting with the value of the very assets.

A New Generation of Carbon Warriors, New Wave of Climate Action

I knew there was something different about Carbon Expo this year as I looked up during the opening ceremony and noticed the room was packed, with standing room only for late arrivals. 

That is when I first asked myself: I know why I am here, but why are you here? I felt like a veteran carbon warrior among a sea of young fresh-faced carbon players.

I started coming to Carbon Expo in 2004, and this year, for the first time, there are plenty of people I don’t recognize. So today I took some time to ask people what they were doing here and why there seems to be a growing interest in carbon markets.

Sustainable Development Gains Require Greater Climate and Disaster Resilience

Average economic losses from natural disasters are rising, despite considerable efforts to better manage risk from natural hazards over the last few decades. Data from Munich Re shows a sharp rise, from $50 billion a year in the 1980s to just under $200 billion annually in the last decade. Population growth, rapid urbanization, and climate change are compounding these losses. Securing prosperity in the midst of growing hazards is an enormous challenge that demands a new approach to development.

The international community is rising to meet this challenge head-on. Last week in Oslo, Norway, I had the privilege of participating in the 15th Consultative Group Meeting for the Global Facility for Disaster Reduction and Recovery (GFDRR), where 75 representatives from partner countries and international development organizations met to help scale up and better mainstream efforts to build climate and disaster resilience in some of the most vulnerable communities around the globe.

With the importance of this effort in mind, I co-authored an article with Norwegian Minister of Foreign Affairs Børge Brende, in which the minister and I argue that sustainable development gains require a new approach towards mitigating risk from climate change and natural hazards. After the recent days spent with my colleagues in Norway, I’m encouraged by the shared enthusiasm of GFDRR and its partners for the task ahead. It’s time to get to work.

Diesel: Emissions, Health, and Climate Impacts

Playing charades with my nine-year-old over the weekend, I was surprised when he gave black smoke as a clue for diesel. When I was his age, I probably would have given bus or truck as a clue.

The word diesel derives from the inventor Rudolph Diesel, who developed a heavy-duty engine in Germany in the late 1800s. Diesel fuel is any fuel used in diesel engines. The combustion of diesel fuel provides the power to move heavy-duty vehicles, such as buses and trucks. It also results in emissions of fine particles, often in the form of black smoke, along with a number of other chemical compounds.

In 2012, the World Health Organization (WHO) declared the emissions from diesel combustion to be carcinogenic. Last month, the WHO released data showing that more than 7 million deaths are caused by indoor and outdoor air pollution. The black smoke from diesel engines is a part of outdoor air pollution contributed by buses and trucks, as my son would tell me after we finished our game.

What he does not know as yet is that a study by a team of international scientists in 2013 noted that diesel smoke consists primarily of black carbon, which has a strong global warming impact on the climate; nearly 3,300 time more than that of carbon dioxide over a 20-year time period.

The one simple and clear message from the triangulation of current scientific evidence is that reducing diesel emissions provides health and climate benefits.
