It is just like some colossally awful house-bidding process. Only here it is not just an attractive three-bed semi-detached residence that is at stake. In the run up to the United Nations Framework Convention on Climate Change (UNFCCC) Conference in Paris in December, each country is submitting its bargaining chip, a so-called Intended Nationally Determined Contribution (INDC).
The levels that countries put forward is part of the complex international climate negotiations – countries are keen to show genuine commitments to climate change action, but very few are willing to rush ahead of other nations.

Today the Lancet Commission on Health and Climate announced the release of their new report “2015 Lancet Commission on Health and Climate Change: Policy Responses to Protect Public Health”.
Following a first report released in 2009, which concluded that “Climate change is the biggest global health threat of the 21st century”, today’s report has a proactive, positive take-home: “tackling climate change could be the greatest global health opportunity of the 21st century.”
Strategically released following the 68th World Health Assembly held last month and in the lead up to the UNFCCC’s COP21, to be held in Paris later this year, the report is the culmination of a second international (predominantly Chinese-European) working group assembled to assess the health impacts of climate change and to identify and accelerate effective mitigation and adaptation policies over the next 5 years.

The term ‘sustainable development’ was first coined in 1987 in the UN’s World Commission on Environment and Development report, Our Common Future. Almost 30 years later, the concept of sustainable development is more relevant than ever.
The definition given in the report is, to this date, the most widely accepted modern definition of the term: ‘Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.’ Climate and society, energy, water, ecosystem health and monitoring, global health, poverty, urbanization, natural disasters, food, ecology and nutrition – these are some of the main problems that need to be tackled when discussing the possibility of sustainable development.
Professor Jo Haigh, Co-director of the Grantham Institute reports back from the Climate Parliament meeting in Lucerne, 12 June 2015.
I have just found a seat on the train from Lucerne to Zurich airport. It is absolutely packed, I suppose, with people going away for the weekend. Staring through the window at the snow-capped mountains, and having spent the day at an inspirational conference set by the beautiful lake, I am wondering quite why anyone would want to leave.
I have been at a meeting of the Climate Parliament. I only learned of this organisation recently but it is rather splendid – a group of legislators from across the world who are concerned about climate change and looking to influence governments to act.

Although both Labour and the Liberal Democrats have pledged to decarbonise the electricity sector by 2030, climate change is unlikely to be a key issue in the run up to the May general election. This reflects a long term decline in political engagement with the problem since the Copenhagen conference in 2009. Although Copenhagen was held in the immediate wake of the global financial crisis, the ongoing recession and drop in living standards have shifted priorities away from tackling climate change. The increasing cost of energy might also have hardened attitudes towards green policies.
This blog post is part of a series on Responding to Environmental Change event, organised by the Natural Environment Research Council (NERC) funded Doctoral Training Partnerships at Imperial (SSCP), and the University of Reading and the University of Surrey (SCENARIO).
A recent event in London brought together emerging environmental scientists (PhD students and early career researchers) with leaders from business, policy and academia to explore the challenges posed by environmental change and opportunities to work in collaboration to respond to these.
Communities today find themselves and the environments they live in under increasing pressure. This is driven by growing populations, urban expansion and improving living standards that place increasing stress on natural resources.

Natural resources are fundamental to human well-being, economic growth, and other areas of human development. Greater demand for food, water and energy resources against the current backdrop of climate change and population growth requires better management and more efficient use of natural resources to reduce the resulting stress on the earth’s natural systems.

Every waking hour, I ingest water. Not always in its purest form, but near enough. Energy is important and right now (and rightly so), carbon is capturing headlines. But water is fundamental to our livelihoods.
The UN has designated 22 March World Water Day: “a day to celebrate water”. And why not? Never mind that it’s essential to all life forms. For modern living, it’s a necessity: we need 10 litres of water to make one sheet of paper; 182 litres to make a kilo of plastic.

It is sometimes claimed that addressing climate change with proper policies is too expensive and could lead to a further decline in the economy. However, the co-benefits of implementation of climate change mitigation strategies for the health sector are usually overlooked. The synergy between policies for climate change mitigation in sectors such as energy use (e.g. for heating), agriculture, food production and transportation may have overall benefits that are much greater than the sum of single interventions (Haines et al, 2009).

This blog forms part of a series addressing some of the criticisms often levelled against efforts to mitigate climate change.
The Twentieth Session of the Conference of the Parties (COP 20) – the latest in a series of meetings of the decision making body of the UN Framework Convention on Climate Change –began in Lima this week. Many in the media are quick to point to the difficulty of obtaining international agreement on greenhouse gas emissions reductions, and to denounce COP 15, which took place in Copenhagen in 2009, as a failure.

This blog forms part of a series addressing some of the criticisms often levelled against efforts to mitigate climate change.
It is often claimed that intermittent renewable sources of electricity (mainly wind and solar photovoltaics), are too expensive, inefficient and unreliable and that we shouldn’t subsidise them.
What are the facts?
Last year, governments spent about $550 billion of public money on subsidies for fossil fuels, almost twice as much as in 2009 and about five times as much as they spent subsidising renewables (IEA, World Energy Outlook 2014). This despite a G20 pledge in 2009 to “phase out and rationalize over the medium term inefficient fossil fuel subsidies” that “encourage wasteful consumption, reduce our energy security, impede investment in clean energy sources and undermine efforts to deal with the threat of climate change”.

The costs associated with reducing emissions in the UK have been discussed recently in the press. In an article in the Mail on Sunday, David Rose made the claim that energy policies shaped by the so-called “Green Blob” – a term coined by Owen Paterson for what he called “the mutually supportive network of environmental pressure groups, renewable energy companies and some public officials” – will cost the UK up to £400 billion by 2030, and that bills will rise by at least a third.
How much will action on climate change actually cost?

Further to previous posts on this blog regarding Owen Paterson’s recent speech to the Global Warming Policy Foundation, I would like to take this opportunity to correct his dismissive statement about biomass energy as a potential contribution to decarbonized energy production in the UK. This is what the former Environment Secretary said:
“Biomass is not zero carbon. It generates more CO2 per unit of energy even than coal. Even DECC admits that importing wood pellets from North America to turn into hugely expensive electricity here makes no sense if only because a good proportion of those pellets are coming from whole trees.
By Dr Simon Buckle, Grantham Institute
Owen Paterson’s remarks on the UK response to climate change miss the point. I do not disagree with him that the UK decarbonisation strategy should be improved. In particular, there is a need for a more effective strategy on energy demand. However, my preferred policy and technology mix would be very different to his and include the acceleration and expansion of the CCS commercial demonstration programme in order to reduce the energy penalty and overall costs of CCS. And without CCS, there is no way responsibly to use the shale gas he wants the UK to produce in the coming decades for electricity generation or in industrial processes, or any other fossil fuels.
