Earth's atmospheric carbon dioxide (CO2) sustains all terrestrial vegetation, yet the effects of increasing concentrations of this gas on plant productivity are difficult to predict. The project aims to undertake experiments on the leaf-level processes that underpin plant productivity in multiple global vegetation systems. This could enable the development of a new theoretical approach to predicting plant productivity in changed environmental circumstances at all scales. The results of this project could provide new tools for understanding the vulnerabilities and sensitivities of natural and managed landscapes under environmental pressures associated with increasing CO2.

地球大气中的二氧化碳（CO2）维持着所有的陆地植被，然而这种气体浓度的增加对植物生产力的影响很难预测。该项目的目的是对在多种全球植被系统中支持植物生产力的叶级过程进行实验。这可以使一个新的理论方法的发展，以预测植物生产力在所有规模的变化环境条件。该项目的结果可以提供新的工具，以了解在与二氧化碳增加相关的环境压力下自然景观和管理景观的脆弱性和敏感性。
