In 1992, governments worldwide agreed to work towards a more sustainable development that would eradicate poverty, halt climate change and conserve ecosystems. Although progress has been made in some areas, actions have not been able to bend the trend in other, critical areas of sustainable development – areas such as those providing access to sufficient food and modern forms of energy, preventing dangerous climate change, conserving biodiversity and controlling air pollution. Without additional effort, these sustainability objectives also will not be achieved by 2050.

Following the United Nations Climate Change Conference in Durban, in 2011, international climate policy has taken a

This paper discusses the method and results of a trend assessment of global CO2 emissions up to 2010 and updates the previous assessment of CO2 emissions up to and including 2009 (Olivier and Peters, 2010). This assessment includes not only fossil fuel combustion on which the BP reports are based, but also incorporates all other relevant CO2 emissions sources including flaring of waste gas during oil production, cement clinker production and other limestone uses, feedstock and other non-energy uses of fuels, and several other small sources.

This report argues that further expansion of the global network of protected areas will be necessary, but will not be sufficient to attain a significant reduction in the rate of biodiversity loss worldwide. Structural changes in consumption and in the efficiency of production are indispensable.

In 2009, for the first time since 1992, there was no growth in global carbon dioxide (CO2) emissions from fossil fuel use, cement production and chemicals production. The recent credit crunch drove many industrialised economies into recession,

In December 2009, an important United Nations climate change conference (COP15) took place in Copenhagen, Denmark. This conference resulted in the Copenhagen Accord, which forms the basis for further negotiations in
Cancun, Mexico, later this year.

This report presents an analysis of, and discussion on, the
environmental, financial and negotiation consequences of
various strategies of dealing with surplus emission allowances
or assigned amount units (AAUs), often known as

This report explores the implications of different possible scenarios on the outcomes of the current climate negotiations.

This report is meant to contribute to the debate between policymakers and research groups on the steps that need to be taken to meet long-term climate targets. This reports shows that the current focus on intermediate targets for the year 2020 needs to be extended to include the long-term targets.

This report focuses on the impact of the evolution of the world oil price on the cost of future GHG mitigation measures. Projections of the cost of mitigation policies are a key input for national and international negotiations on future mitigation of GHG emissions among public policy makers and other stakeholders.
