    How changes in the prices of milk and beef affect deforestation in Brazil

How changes in the prices of milk and beef affect deforestation in Brazil

At first glance, this may seem like a trivial question but in the context of the Brazilian Amazon, heavily deforested over the last half-a-century, understanding the links between commodity prices and deforestation is important given ever-increasing demand for beef and dairy products. Tropical forests host critical biodiversity ‘hotspots’ as well as providing a range of important ecosystem services, in […]

Saving energy when it matters most

Unlike most other goods, electricity cannot be cost-effectively stored even for short periods. Supply must always meet demand, or you have blackouts. In addition, electricity demand is highly variable and inelastic (Ito 2014). As a result, electricity markets clear mostly on the supply side, with production ramping up and down to meet demand (Borenstein 2000, Griffin and Puller 2005). […]

    Theresa May should press President Trump about his actions on climate change

Theresa May should press President Trump about his actions on climate change

On 13 January, the office of the Prime Minister, Theresa May, received a letter signed by 100 members of the climate change research community about the potential threats to, and opportunities for, the UK national interest arising from the recent elections in the United States.

I had signed the letter after becoming concerned by alarming reports of plans that could […]

    Where mining takes place, food production takes a hit in Ghana

Where mining takes place, food production takes a hit in Ghana

The device you are using to read this blog contains at least a dozen different types of minerals, many of which most likely come from modern large-scale mines in developing countries. As these mining operations tend to be located in poor rural locations, the question of how neighbouring populations are affected by their expansion becomes an interesting one. The […]

Why electric cars aren’t always environmentally sound

Electric cars are often advertised as “zero emission vehicles”. Although it is true that they don’t have tailpipes, electric cars are charged from the electrical grid, and most electric power plants release air pollution emissions through their smokestacks. So which is cleaner, tailpipes or smokestacks?

As with real estate valuation, the answer depends on three factors: location, location, location. In […]

Four trends are reshaping the European energy system. Decarbonisation and digitalisation are leading to decentralisation and convergence. Thanks to strong public policy decisions, decarbonisation is reshuffling the European energy mix. Meanwhile, innovation in digital technologies is enabling disruptive changes in the management of energy systems. This is […]

It is in Europe’s interest to foster stability, security and prosperity in North Africa. But so far Europe’s attempts to promote economic and political reform in the region have failed. The aftermath of the so-called ‘Arab Spring’ demonstrated the limitations of the EU’s leverage over economic and political developments in North Africa. But […]

The new UK Government under Prime Minister Theresa May has committed to boosting UK productivity and addressing the widening wealth gap. Achieving all this will require the right investments by both the public and private sectors at a time of heightened economic uncertainty.

The UK Government could improve economic growth by taking advantage of negative […]

The UK will soon break ground on its first new nuclear power plant in more than 20 years now that PM Teresa May has signed off on Hinkley. While clearly a political decision, given the involvement of both French and Chinese companies, my colleagues and I at Bloomberg New Energy Finance […]

    When enough countries lead by example, they create a tipping point for climate agreements

When enough countries lead by example, they create a tipping point for climate agreements

Avoiding dangerous climate change is one of the most complex problems for international cooperation. It requires overcoming several barriers to collective action and success hinges on widespread cooperation by countries faced with incentives to delay costly mitigation and free-ride on the efforts of others.

The United Nations Framework Convention on Climate Change has warned that climate change may be “abrupt […]

    Climate change impacts the economic development of low-income countries

Climate change impacts the economic development of low-income countries

The Earth has warmed on average by about 1 degree Celsius since the late 19th century. Regardless of international commitments to reduce emissions, further substantial warming is now locked in for the next several decades at least. The worst effects of this warming, for societies and economies, will be felt in low-income countries, where livelihoods depend strongly on the […]

    Euro zone crisis and climate change: Addressing two targets with one instrument

Euro zone crisis and climate change: Addressing two targets with one instrument

The threat of climate change requires a transition of society away from fossil fuels towards renewable energies. Such transition cannot be achieved in a context of economic stagnation. The deplorable state of the European economy is the direct consequence not of the financial crisis of 2008/09, but of the seemingly unsolvable euro zone crisis. This places the long-term challenge […]

Africa’s Nile basin countries should invest in rain, not big infrastructure projects

Last month the The African Ministers’ Council on Water (AMCOW) and over 1000 experts gathered in Dar es Salaam during the Africa Water Week to discuss new pathways for development and increased investment in water infrastructure. The challenges are huge; the El Nino of last year showed the exposure of African economies to the vagaries of weather. Climate change […]

How Brexit will affect climate change policy

It is still too early to know all the ways in which the UK’s departure from the European Union will affect the climate change policy of the 28 current Member States, but some things now seem likely if not inevitable.

‘Brexit’ will not be completed for at least two years, particularly as the UK has not yet activated Article 50 […]

    Environmental disclosure: corporate accountability or greenwashing?

Environmental disclosure: corporate accountability or greenwashing?

Nearly all of the 100 largest companies in Japan, France, and the United Kingdom — and the vast majority of such companies in the United States — issue sustainability reports. These very high reporting rates reflect increasing pressure on companies from stakeholders — including investors, consumers, governments, and civil society — to be more transparent about their environmental impacts.

    When disaster strikes, who pays for the impacts of climate change?

When disaster strikes, who pays for the impacts of climate change?

The Paris Agreement on Climate Change calls for further emission reductions, more efforts to increase our resilience to climate impacts, and support for those who are affected by a changing climate. Under the heading ‘Loss and Damage’ this third pillar of the international climate architecture has gained prominence over the last few years and is now an official element […]

    Don’t try to convince your employees to become environmental advocates

Don’t try to convince your employees to become environmental advocates

Improving environmental performance remains a key concern for many organisations, with consumer and NGO expectations regarding sustainability increasing. Whilst much attention has focussed upon adopting new technologies, supply chain innovations and production efficiencies, there has been a growing appreciation of the role that individual employees may play in reducing the environmental impact of an organisation’s activities.

Organisations and academics have […]

    As China uses less coal, its emissions of CO2 may be past their peak

As China uses less coal, its emissions of CO2 may be past their peak

Something quite remarkable is happening in China. The country’s coal use grew at more than eight per cent per year between 2000 and 2013. But, in 2014, coal use barely grew at all and then it actually fell by more than three per cent in 2015.
