Christy Clark is the premier of British Columbia, which has had a revenue-neutral carbon tax since 2008. She spoke ahead of the UN Secretary-General's Climate Leadership Summit about the impact of carbon pricing on the economy.

We often hear claims that a carbon tax would destroy jobs and growth. Yet the evidence from a Canadian province that actually passed such a tax – British Columbia – tells a very different story.
The latest numbers from Statistics Canada show that B.C.’s policy has been a real environmental and economic success after six years. Far from a “job killer,” it is a world-leading example of how to tackle one of the greatest global challenges of our time: building an economy that will prosper in a carbon constrained world.
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.
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.
For those plugged into the climate change conversation, land use and “climate-smart agriculture” (CSA) are hot topics, especially in the lead up to September’s UN Summit on Climate Change.
There is tremendous urgency in moving this agenda forward. We are now beyond discussing whether we need sustainable intensification. To enhance food security in the face of climate change, we will need agriculture systems that are more productive, use inputs more efficiently, and are more resilient to a wide and growing range of risks. This will mean changing the way land, soil, water, and other inputs are managed. But because agriculture varies from place to place, and climate change will impact each location differently, climate-smart agriculture needs to respond to local conditions. It is not a one-size-fits-all approach to agriculture, but rather a framework to be applied and adapted – a paradigm shift in thinking and action.
On the occasion of the release of the new Intergovernmental Panel on Climate Change (IPCC) report on the Mitigation of Climate Change last week, I had an opportunity to hear from some of the leading experts and policymakers and to zoom in on one of CSA's three goals, along with increasing productivity and building resilience: meeting global food needs with lower emissions.
Unfortunately, global agriculture systems have a long way to go before they can be considered sustainable by any reasonable standard. And we are certainly far away from being a sector that has a reduced or low footprint: The way we manage our agricultural landscapes globally produces a quarter of global greenhouse gas emissions. Agriculture poses a bigger emissions problem than transport and other sectors that are traditionally viewed as the big emitters.
While many may have heard the statistic “Cities are home to 50% of the world’s population”, few realize that it leads directly to a sobering and much less hyped conclusion: we face an urgent need to understand how our cities work.
Cities are now the defining human organizational structure on earth, but what do we know about these creations? Sadly, not enough. Which is why collecting and disseminating high-quality data about cities and how they function is of critical importance.
Carbon Disclosure Project (CDP) has recently taken a giant step in this direction by making our 2013 data set on over 100 large cities, their greenhouse gas emissions, and their actions on climate change available for free download in CSV files via our website. This effort—made possible by a grant from Bloomberg Philanthropies and our long-term partnership with C40—brings our voluminous data into the public domain for the first time.
Climate change is a threat to global development and to poverty alleviation. And yet, reducing greenhouse gas emissions is proving difficult because all players in an economy contribute to the problem. To make a difference, we must reduce our emissions in a coordinated manner.
This is no easy task. So where do we go from here?
One approach involves pricing the “externalities” that are contributing to climate change. Pricing externalities into the costs of production is nothing new. A classic textbook example is the paper mill that sits upstream from a fishing village.
Discharge from the mill pollutes the river, diminishing the fishermen’s catch. The mill freely uses the water of the river in its production of paper, but does not pay for the damage of the negative externality that it causes. To remedy the situation, regulations can be put in place to stop waste from going into the river – or the mill can pay a fine equivalent to the loss of the fishermen’s revenue.
The latter is an example of an externality priced into the cost of production. The same can be done to combat climate change.
In this case, carbon emissions are the externality that must be priced. Doing so provides a cost-effective and efficient means to drive down greenhouse gas emissions as the cost of such pollution goes up.
Cities are the world’s engines of economic growth, but they also account for 70 percent of global greenhouse gas emissions and many metropolitan areas struggle with traffic congestion, lost productivity, public health problems and traffic deaths due to inadequate public transportation.
How can we make our cities livable, inclusive, prosperous and green?
Last month, I drove through dust on bumpy dirt roads from Nairobi to visit the Oloirowua Primary School in Suswa, 140 kilometers northeast of the Kenya capital. The school sits on the vast savannah near Hell’s Gate National Park, an area with substantial geothermal potential.
At the school, classes are being taught outdoors and kids sit under a few trees with notebooks in their laps. Their old and crumbling school will soon be replaced by a new building that will accommodate 200 students. Their faces light up when they talk about the new school, and I feel thankful for being able to work with projects like this where I see the direct effects of our work on kids’ education.
