ECE’s overarching vision is to provide evidence-based, scientific roadmaps for feasible systems transformations that simultaneously meet the Sustainable Development Goals (SDGs) and ambitious climate change mitigation targets.

Emphasis is placed specifically on local policy decisions and actions required in the short term to put the world on track to achieve long-term targets while assuring human health, wellbeing, and the reduction of social inequalities in a socially and economically sustainable manner. The program’s systems analytical tools enable it to act as an objective scientific broker in support of sustainable transformational processes. ECE combines the research portfolios of the former Air Quality and Greenhouse Gases, Energy, and Transitions to New Technologies programs.

How we choose to end deforestation will impact future emissions

The Glasgow Leaders’ Declaration on Forests and Land Use signed at COP26 represents a commitment by leaders representing over 85% of the world’s forests to halt and reverse deforestation and land degradation by 2030. But could the declaration’s ambitions be too ambiguous? An international team of researchers looked into this question.

The concept of nexus thinking has gained traction amongst the applied research community to examine cross-sector linkages between land, water, and energy strategies. A nexus approach identifies the interactions among sectors to better understand the synergies and trade-offs involved in meeting future resource demands in a sustainable way.
