COP21 daily report: Will we trust governments on climate?

Cabot Institute Director Professor Rich Pancost will be attending COP21 in Paris as part of the Bristol city-wide team, including the Mayor of Bristol, representatives from Bristol City Council and the Bristol Green Capital Partnership. He and other Cabot Institute members will be writing blogs during COP21, reflecting on what is happening in Paris, especially in the Paris and Bristol co-hosted Cities and Regions Pavilion, and also on the conclusion to Bristol’s year as the European Green Capital.  Follow #UoBGreen and #COP21 for live updates from the University of Bristol.  All blogs in the series are linked to at the bottom of this blog.

Whatever comes of the climate summit that kicked off Monday in Paris, the negotiations will be intense. Signatories of the UN’s Framework Convention on Climate Change meet every year, but this year is exceptional. The stakes are high, with governments and their negotiators seeking to finalize a landmark treaty that will guide the world’s actions for many years to come with respect to greenhouse gas emissions and the climate change they cause.

Despite the heat that the negotiations in Paris will surely generate, though, in a sense dealing with climate change could actually be… surprisingly easy. The world’s leading climate economist thinks it would cost only about 2% of GDP to get the world on track to avoid the worst effects. That’s not a lot to pay to solve perhaps the most serious challenge confronting humanity.

Why then is it proving so hard for us to buy a climate-friendly economy?

Part of the problem is that public opinion is pretty hostile to the number one thing that could get us there: making polluters pay taxes if they want to pollute.

The logic is simple. People buy less of something when it gets more expensive. Raising the price of polluting activities is therefore the most effective, direct, and time-tested way of getting people to live–produce and consume–in ways that cause less damage to the environment.
"Raising the price of polluting activities is therefore the most effective, direct, and

In principle, there should be no reason for people not to like the idea. Governments can lower taxes on things that do no harm (income and labour) while raising them on things that do (emitting greenhouse gases, leaching waste into groundwater, driving a car on congested streets at rush hour). Tax shifts of this kind have no net effect on public finance, and at most a very small one on household budgets–but they can make a big dent in environmental degradation.

Take the case of Canada. In 2008, a right-of-centre government in the western province of British Columbia (BC) introduced a C$30/ton tax on carbon emissions. The rest of Canada did not. Over the course of the next several years, consumption of fossil fuels in British Columbia dropped significantly, while consumption elsewhere didn't. Meanwhile, BC enjoyed faster economic growth than the average across the other provinces.

But cases like British Columbia’s are exceptional. In most places, public opinion has been too hostile to new taxes of any kind for governments to raise taxes even on pollution and the use of scarce resources. In 2013, for example, Australians voted out a government that had brought in a carbon tax much like British Columbia’s, and they voted in a government that repealed the tax. Earlier this year, the Swiss voted down new carbon taxes in a referendum.

Perhaps the biggest reason why people around the world don’t want green taxes is political distrust. Even though such taxes have a great track record, people simply don’t trust governments to make good use of taxes–of any kind. They worry that tax revenues disappear into the pockets of politicians and bureaucrats, never to be seen again. Some think it’s unfair to tax people for behaviours that are hard to avoid–like heating your home or catching a flight for the occasional family holiday. So they don’t like green taxes, and that’s true even though most people say they believe in the seriousness of climate change, and of environmental problems generally.

To illustrate the point, in an experiment I conducted in Britain last year, I randomly assigned survey respondents to different versions of a question about their willingness to pay higher taxes to protect the environment. People were much more open to the idea if they were told that other taxes they pay would be reduced to compensate. So it seems that revenue neutrality can win over a lot of people. But telling respondents that the offsetting cuts to other taxes were only a government “promise” reduced much of the positive impact of revenue-neutrality. Clearly, government promises don’t cut much weight, at least with Britons. (Experiments with other populations elsewhere are ongoing.)

Advocates for better environmental policy have typically focussed on getting the word out about the seriousness of the problems the policies are meant to address. But, in another recent study, I conducted a head-to-head test of the scope for expanding public acceptance of environmental taxes if only one of (a) concerns about environmental problems or (b) political trust were to increase. Because there is already a lot of concern about environmental problems, but not a lot of political trust, it turns out that the potential impact of the latter looks much greater in most countries.

For that reason, along with alerting people to all the ways in which people are doing serious harm to the environment globally and locally, it would also be good to get the word out about the many environmental policies that have been tremendously successful. Globally, we've built a regime to stop depleting the ozone layer; many countries have reduced acid rain dramatically; some formerly endangered species are no longer endangered. If more people thought about how much good past environmental policies have done, they might be more inclined to support efforts to do more.

Powering the economy through the engine of Smart Local Energy Systems

How can the Government best retain key skills and re-skill and up-skill the UK workforce to support the recovery and sustainable growth? This summer the UK’s Department for Business, Energy and Industrial Strategy (BEIS) requested submission of inputs on Post-Pandemic Economic Growth. The below thoughts were submitted to the BEIS inquiry as part of input under the EnergyREV project . However, there are points raised here that, in the editing and summing up process of the submission, were cut out, hence, this blog on how the UK could power economic recovery through Smart Local Energy Systems (SLES). 1. Introduction: Factors, principles, and implications In order to transition to a sustainable and flourishing economy from our (post-)COVID reality, we must acknowledge and address the factors that shape the current economic conditions. I suggest to state the impact of such factors through a set of driving principles for the UK’s post-COVID strategy. These factors are briefly explained belo

Farming in the Páramos of Boyacá: industrialisation and delimitation in Aquitania

Labourers harvest ‘cebolla larga’ onion in Aquitania. Image credit: Lauren Blake. In October and November 2019 Caboteer  Dr Lauren Blake  spent time in Boyacá, Colombia, on a six-week fieldtrip to find out about key socio-environmental conflicts and the impacts on the inhabitants of the páramos, as part of the historical and cultural component of her research project, POR EL Páramo . Background information about the research can be found in the earlier blog on the project website . Descending down the hill in the bus from El Crucero, the pungent smell of cebolla larga onion begins to invade my nose. The surrounding land transforms into plots of uniform rows of onion tops at various stages of growth, some mostly brown soil with shoots poking out along the ridges, others long, bushy and green. Sandwiched between the cloud settled atop the mountainous páramos and the vast, dark blue-green Lake Tota, all I can see and all I can smell is onion production. Sprinklers are scattered around, dr

IncrEdible! How to save money and reduce waste

The new academic year is a chance to get to grips with managing your student loan and kitchen cupboards. Over lockdown the UK wasted a third less food than we usually would. This is brilliant, as normally over 4.5 million tonnes of edible food is wasted from UK homes every year. For students, it’s even higher. The average cost of food waste per student per week is approximately £5.25 - that's about £273 per year !  It’s not just our bank accounts that are affected by food waste – it’s our planet too. The process of growing, making, distributing, storing and cooking our food uses masses of energy, fuel and water. It generates 30% of the world’s CO₂ greenhouse gas emissions. The same amount of CO₂ as 4.6 million return flights from London to Perth, Australia! So it makes sense to keep as much food out of the bin as possible, start wasting less and saving more.  Start the new term with some food waste busting, budget cutting, environment loving habits! Here’s five easy ways to reduce
