Lady Worthington was the lead author in the team which drafted the UK's 2008 Climate Change Act. This landmark piece of legislation requires the UK to reduce its carbon emissions to a level 80% lower than its emissions in 1990. At the time Worthington was working with Friends of the Earth working on their Big Ask campaign, but was seconded to government to help design the legislation.
Sandbag
Lady Worthington launched Sandbag in 2008 to raise public awareness of and improve the European Union's Emissions Trading Scheme. Initially Sandbag provided members of the public with a way of tackling climate change, enabling them to buy ETS permits and cancel them, meaning that European companies covered by the ETS would have to emit fewer greenhouse gasses. Since that time, Sandbag has changed and grown. With a general remit to 'defend against climate risk', Sandbag now focuses on researching and suggesting improvements to the ETS, how to phase out coal-fired power stations in Europe, and how governments and the EU can work to support Carbon Capture and Storage. Lady Worthington has been Sandbag's Director since its foundation.
Other Campaigning
Nuclear Power
The Baroness was once "passionately opposed to nuclear power," but came to advocate the adoption of Thorium as a nuclear fuel following the 2009 Manchester Report, where she met Kirk Sorensen who presented arguments for using Thorium. She has said: "the world desperately needs sustainable, low carbon energy to address climate change while lifting people out of poverty. Thorium based reactors, such as those designed by the late Alvin Weinberg, could radically change perceptions of nuclear power leading to widespread deployment." Worthington was patron and trustee of The Alvin Weinberg Foundation, a British non-profit, non-governmental organization dedicated to the promotion and development of molten salt reactor technology. In response to an open letter published in The Ecologist in 2015 criticising her position on nuclear power, Worthington wrote: "It is clear that as is the case with every technology, there are more appropriate and less appropriate ways of using it and I am no apologist for the mistakes that have been made in the nuclear industry. As a proven source of reliable low carbon energy it would, however, be reckless to rule it out in the fight against climate change just as it would be reckless to rule out large scale hydro, solar, biomass, wind and carbon capture and storage. Nuclear power is the most concentrated source of power available today with the smallest footprint. It is not without its challenges but these are not insurmountable."
