The transport sector is consistently responsible for around 30 per cent of carbon dioxide emissions in developed countries and is one of few sectors where emissions continue to increase as a result of apparently insatiable demand for road and air travel. This paper examines how the formulation of transport policy fits into the exposition of UK climate policy, focusing on three principal areas of tension: policy priority (congestion and carbon reduction); strategies to reduce emissions (technological and behavioural solutions) and timescale (short- and long-term vision). We suggest that in overcoming such tensions government ministers will need to devolve significant policy formulation and implementation powers to an appropriate scale of governance – in this case the city-region – to fashion a ‘convergence space’ capable of promoting meaningful action with regard to transport's climate impact.

1. Hydrologically open lakes in temperate regions are not considered as sensitive to climate change as closed-basin lakes in semiarid regions. 2. Oak Mere is an acid lake in lowland UK. It has no surface inflow or outflow but is connected to the regional groundwater. It is a high landscape, hydrologically open lake. 3. This paper describes how Oak Mere responded to drought with rapid and substantial changes in acidity and nutrients. Decreases in pH and catchment-derived nutrients appear to be a response to the relative amount of catchment-derived minerals compared with those received in direct precipitation. 4. The extreme sensitivity of the site appears to be due to negligible groundwater inputs, low buffering capacity and a short retention time. 5. The paper demonstrates that high landscape sites may represent the most sensitive hydrologically open lakes to climate change. This not only has consequences for acidification and eutrophication studies. These sites may also be considered valuable in that they potentially offer an important new archive for palaeoclimate studies, with a sensitivity previously considered unavailable in low altitude temperate regions.
