What is the geographical distribution of CO2 emissions? This column identifies the Earth’s “polluting centre of gravity” since 1970. It is heading east faster than GDP, which suggests that Asian production is getting more carbon-intensive.

US climate change policy seems likely to include border measures to address competitiveness concerns. This column warns against such measures, arguing that they will do little to protect US industries, expose the US to retaliatory trade restrictions, and significantly burden the global trading system. The US would be better served by addressing its competitiveness concerns in international negotiations.

The future of climate change policy is very uncertain due to economic, environmental, and political complexities. This column quantifies the economic cost of delaying action to reduce carbon emissions and argues that the best strategy is to hedge our bets by adopting a mild emissions reduction policy now rather than naïvely waiting for the uncertainties to be resolved.

Since the 1970s, US manufacturing output has risen by 70% but air pollution has fallen by 58%. Was this due to improved abatement technology or shifting dirty production abroad?

Targets and trading must be at the heart of a global agreement to reduce greenhouse gas emissions, according to Sir Nicholas Stern delivering the Royal Economic Society’s 2007 annual public lecture today, ahead of next week’s world summit on climate change in Bali.

Quantitative emission targets for the 21st century must be set sequentially, a decade at a time, within a long-term framework. A good analogy is the GATT, which produced 50 years of trade liberalisation, the specifics of which the original signers could only have guessed.
