Bank of England Governor speaks out on financial risks caused by climate change

Mark Carney, Governor of the Bank of England, spoke on the topic "Breaking the tragedy of the horizon - climate change and financial stability" at Lloyd's of London on 29 September 2015. He said that there was a growing international consensus that climate change is unequivocal. While there is always room for scientific disagreement about climate change (as there is with any scientific issue), he said that he had found that insurers were amongst the most determined advocates for tackling it sooner rather than later.

Key points he made included:

We don't need an army of actuaries to tell us that the catastrophic impacts of climate change will be felt beyond the traditional horizons of most actors - imposing a cost on future generations that the current generation has no direct incentive to fix.

The horizon for monetary policy extends out to 2-3 years. For financial stability it is a bit longer, but typically only to the outer boundaries of the credit cycle - about a decade.

In other words, once climate change becomes a defining issue for financial stability, it may already be too late.

He concluded is speech by saying:

Our societies face a series of profound environmental and social challenges.

The combination of the weight of scientific evidence and the dynamics of the financial system suggest that, in the fullness of time, climate change will threaten financial resilience and longer-term prosperity.

While there is still time to act, the window of opportunity is finite and shrinking.

Others will need to learn from Lloyd's example in combining data, technology and expert judgment to measure and manage risks.

The December meetings in Paris will work towards plans to curb carbon emissions and encourage the funding of new technologies.

We will need the market to work alongside in order to maximise their impact.

With better information as a foundation, we can build a virtuous circle of better understanding of tomorrow's risks, better pricing for investors, better decisions by policymakers, and a smoother transition to a lower-carbon economy.

By managing what gets measured, we can break the Tragedy of the Horizon.

Open for business, even in severe weather?

Two-thirds of small businesses have been hit by the negative impacts of severe weather in the past three years, says a new report from the Federation of Small Business (FSB) published in July. 'Severe weather - a more resilient small business community' also shows that many small businesses need further support if they are to be resilient to severe weather. Recommendations from the FSB include encouraging small businesses to develop their own resilience plans, and calling on the government to take steps to ensure affordable flood insurance.

According to the report:

  • the financial cost of these severe weather events over this period was, on average, just under 7,000 for each affected business;
  • disruptions to people (customers and staff) and logistics (supply chain, utilities and transport) are the most frequently occurring problems for small businesses during severe weather events;
  • only 25 per cent of microbusinesses (those with fewer than 10 employees) have a resilience plan in place that specifically includes severe weather;
  • small businesses with previous experience of severe weather are more motivated to prepare resilience plans;
  • 93 per cent of small businesses believe severe weather poses a risk to some part of their business.

A cleaner, solar powered future?

The sunlight that hits the earth in an hour contains enough energy to run the global economy for a year
Sustainable Business magazine

According to the International Energy Agency (IEA) the role of renewable sources of energy (solar, wind, geothermal, hydropower, bioenergy and ocean power) in the global power mix continues to increase rapidly as renewables maintain the lead as the fastest-growing power source. As global renewable electricity generation expands in absolute terms, it is expected to surpass that from natural gas and double that from nuclear power by next year (2016), becoming the second most important global electricity source, after coal.

Globally, renewable generation is estimated to rise to 25% of gross power generation in 2018, up from 20% in 2011. The IEA expects solar to become the biggest single source of energy by 2050 and the dramatic falls in cost of solar PV means that the sector in 2014 was around five years ahead of where the IEA had previously thought it would be.

The IEA's 2014 report "Technology Roadmap - Solar Photovoltaic Energy" envisioned that up to 16% of global electricity will be from solar PV by 2050. For bulk power on the grid, PV electricity can already be price competitive at times of peak demand, especially in areas where peak electricity is provided by burning oil products.

A more rapid move towards solar energy has many benefits, especially as improved energy storage technologies are developed. As the IEA points out, solar energy is widely available throughout the world and can contribute to reduced dependence on energy imports. As it entails no fuel price risk or constraints, it also improves security of supply. Solar power enhances energy diversity and hedges against price volatility of fossil fuels (oil and gas), thus stabilising the cost of electricity generation in the longer term.

Once PV panels have been manufactured, solar PV entails no greenhouse gas (GHG) emissions during operation and does not emit other pollutants (such as oxides of sulphur and nitrogen); additionally, it consumes no or little water. As local air pollution and extensive use of fresh water for cooling of thermal power plants are becoming serious concerns in hot or dry regions, these benefits of solar PV become increasingly important.

The faster than expected advancement in the efficiency of renewable energy technologies such as solar PV, has meant renewables are projected to generate more electricity than the UK Government had previously projected. This has in part led to the Government's announcement on 22 July that it planned to reduce or end support for renewable energy. Whether this puts at risk investor confidence and future investments that might otherwise have further accelerated the downward cost of solar PV electricity production remains to be seen.

Industrial nations agree to phase out fossil fuels

Climate change is not an environmental issue, but much more to do with security and economics
- Jonathon Porritt

The G7 leading industrial nations (Canada, France, Germany, Italy, Japan, United Kingdom, and the United States) have agreed to cut greenhouse gases by phasing out the use of fossil fuels by the end of the century at their summit in June. Summit host German Chancellor Angela Merkel said they had committed themselves to the need to "decarbonise the global economy in the course of this century". They also agreed on a global target for limiting the rise in average global temperatures to a maximum of 2C compared to pre-industrial levels.

Whilst G7 leaders did not support Angela Merkel's proposal to agree to immediate binding emission targets, they agreed to back the recommendations of the UN Intergovernmental Panel on Climate Change (IPCC), to reduce global greenhouse gas emissions at the upper end of a range of 40% to 70% by 2050, using 2010 as the baseline.

The United Nations Climate Change Conference, COP21, will be held in Paris from 30 November to 11 December 2015. The objective will be to achieve a legally binding and universal agreement on climate, from all the nations of the world. The G7 commitment on phasing out fossil fuels is a hopeful sign that real progress will be made in Paris.
